  • Spring Wildflower Identification and Ecology Course (Classroom, Online and Field)

    • 15 Mar 2026
    • 04 Apr 2026
    • 4 sessions
    • 6908 Belair Rd, Natural History Society of MD, Online via Zoom, Potomac

    Join waitlist

    If you want to start or improve your wildflower identification skills, springtime is a great season to start, since there are fewer species to learn and many are distinctive. The most spectacular wildflower displays in our area are in our woodlands in spring. Many of these flowers are ephemeral, appearing for a short time each spring, so timing to observe them is critical. The class will explore the lives of these blooms from tiny hepatica to riverbanks filled with stunning bluebells. With a focus on plant families, we will also cover how to differentiate between trickier species. Spring wildflowers have many incredible adaptations to overcome seasonal vagaries from low temperatures to short growing seasons, and deserve our admiration.

    The complete course is 9 hours in length, divided over four days and three platforms: in-person, online, and in the field.

    • Sunday, March 15 – Classroom Session (1-4 pm)
    • Two Fridays, March 20 and 27 – Zoom Session  (7-8:30 pm)
    • Saturday, April 4,  Field Trip (9-12 pm)

    The classroom session will cover the basic terminology required for the identification of flowers by examining plant parts. In groups, we will then work through plant identification while comparing Newcomb’s wildflower guide to apps available on your phone.

    The online sessions will continue our exploration of plant families seen in the area and explore their ecological connections. By looking at relationships between these plants and their pollinators and their seed dispersers, you will gain an understanding of each flower’s role in the ecosystem.

    The field trip features one of the area’s best wildflower locations, the Potomac Gorge either the Carderock Recreation Area or Turkey Run Park (depending on which area is at peak early bloom). Both locations are free to access and have large parking areas and bathroom facilities.

    ABOUT YOUR INSTRUCTOR: Clare Walker teaches plant and pollinator identification and classes on natural basketry and more around Maryland, including programs at Nature Forward, the US Botanical Gardens, and Irvine Nature Center. She delights in native plants and especially their relationships to wildlife and people. Her classes encourage us to cherish our local plants, whether through basketry using natural materials, making herbal remedies, enjoying foods from foraged plants, or by gardening with natives. Clare previously worked as a naturalist for Maryland State Parks and then as an environmental outreach specialist for the Maryland Department of Natural Resources.

  • Building Accessible Birding Programs and Places Online Workshop

    • 17 Mar 2026
    • 4:00 PM - 6:30 PM
    • Online via Zoom
    Register

    This extended workshop builds on the introductory presentation, Birding CAN Change the World, and is designed for those who are ready to move from learning into implementation.

    Participants will take a deeper dive into what accessibility in birding truly looks like in practice. Together, we will explore real-world case studies from across the country that show how organizations, municipalities, parks, and nature centers have assessed barriers, made meaningful changes, and created more inclusive birding experiences for people with disabilities and other health concerns.

    Led by Birdability Executive Director Cat Fribley, this session will take participants through Birdability’s approach to accessibility assessment and planning. We will examine common challenges and misconceptions, share practical strategies that work at various scales and budgets, and discuss how to center the voices of disabled birders and the community in decision-making. Participants will learn how to evaluate trails, programs, events, and communication materials through an access lens, and how to prioritize improvements that create lasting impact.

    Attendees will leave with concrete tools, frameworks, and next steps they can use immediately to advance accessibility and inclusion in their own work. By the end of this session, participants will be better equipped to move beyond intention and toward action, helping ensure that birding and nature spaces and programs are welcoming, usable, and meaningful for every body and every mind.

    NOTE: It is advised though not required to attend the March 5, introductory Zoom session on Birdability. This is free, but you must RSVP to have the Zoom details emailed to you.

  • Archaeology Club: Exploring the Buried Past through Archaeology at Hampton National Historic Site

    • 18 Mar 2026
    • 7:00 PM - 8:30 PM
    • Online via Zoom
    Register

    At the center of the once-sprawling Ridgely family property, the Hampton mansion and its surrounding grounds represent the intact core of an 18th-century plantation with remarkable integrity. The house itself, along with numerous outbuildings, an icehouse, quarters for enslaved people, and intact formal gardens, powerfully conveys the stories of one of Baltimore’s wealthiest families as well as those free and enslaved who worked on their lands.  Additionally, Hampton is a wonderfully complex archaeological site, and the features and artifacts there have the potential to inform us further about those people’s daily lives. Archaeology has been going on at Hampton for many years, but recent efforts to rehabilitate some of the standing buildings there, part of a major effort supported by the National Park Service’s Legacy Restoration Fund, have led to a sharp increase in archeological efforts in recent years. These have included a comprehensive geophysical survey of the property and, most recently, a data recovery excavation in the vicinity of the quarters for the enslaved there.

    David Gadsby has been a Chesapeake archeologist since the age of 19, when, as a student at Saint Mary’s College of Maryland, he assisted with his first dig at Historic Saint Mary’s City. Since then, he has gone on to work throughout the region, studying the development of 17th-century Anne Arundel County and urban transformation in Baltimore’s Hampden neighborhood, among other topics. He holds a Master’s degree from the University of Maryland and a Ph.D. from American University. Since 2008, he has worked as an archeologist with the National Park Service. Among other duties, he serves as archeological advisor to Hampton National Historic Site and Fort McHenry National Monument and Historic Shrine.

    This meeting of the NHSM Archaeology Club will take place on Zoom. In order to receive the Zoom link you need to register. It is free and open to the public, although non-members are asked to please donate $5 to support the club.

    When you register for the program, you’ll receive the Zoom link and passcode via email with your registration confirmation. Please contact the community coordinator (rbaldwin@marylandnature.org) with any questions.

    NHSM’s Archaeology Club was founded in 2019 to promote the value of archaeology in Baltimore City, Baltimore County, and surrounding areas. The goal of the club is to educate citizens and residents in the ethics and methods of archaeology and to document, discover, and promote local history. The Arch Club is inclusive of all persons who have an interest in archaeology.

    Although you don’t need to be a member to attend a meeting, membership gives you access to additional experiences. Annual NHSM membership is $35 for individuals, $50 for families; Arch Club membership is an additional $5 for individuals and $10 for families.

  • Thomas Say: An Exceptional American Naturalist

    • 19 Mar 2026
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Thomas Say (1787–1834), a native Philadelphian, led a brief yet extraordinary life marked by adventure, intellectual curiosity, and scientific achievement. A founding member of the Academy of Natural Sciences of Philadelphia in 1812, Say participated in the Academy’s 1817 expedition to Florida and later joined Major Stephen Long’s 1819 journey to the Rocky Mountains. In 1825, he aligned himself with social reformer Robert Owen in the ambitious, though short-lived, experiment to establish a utopian community in New Harmony, Indiana. It was there that Say married and soon embarked on another scientific expedition, this time to Mexico.

    Say’s legacy lies in his foundational contributions to American taxonomy. He described over 1,500 insect species, more than 100 mollusks, and numerous other animals, including the coyote, which still bears the scientific name Canis latrans that Say assigned. Though he likely never set foot in Maryland, Say published the first formal treatise on the state’s fossil shells in 1824, demonstrating his wide-ranging influence.

    Remarkably, Say had only three years of formal education. A self-taught naturalist, he cultivated his expertise through observation, correspondence, and relentless study. The presentation will conclude by exploring how Say educated himself and speculating on his broader views of the natural world—topics on which, intriguingly, he left little written record.

     A native of Turkey, Aydin Orstan has a Ph.D. in chemistry, but his first love is natural history. He is a research associate at the Carnegie Museum of Natural History in Pittsburgh, but conducts research work in the basement of his house in Maryland.

    Register

    Congratulations on persevering through that unseasonal winter. Finally, we’ve made it to skunk cabbage season! But does it still seem too early for wildflowers in Maryland? Surprisingly, no. The Eastern Skunk Cabbage has evolved many traits over the last 72,000 years, and blooming in cold weather is only one of many abilities that make it unique in the plant world. Join us for a hike to learn more about how this remarkable plant has adapted to life in our wetlands with ecologist John Canoles. We’ll also bird to look for wintering guests and local residents and learn about native and invasive plants we see along the way.

    Be prepared for cold weather, mud, and soggy conditions. We will manage our footsteps around the area to leave limited traces of our admiring presence. Hiking poles can help with stability in mucky areas. Hiking distance should be one to two miles.

    John Canoles is an ecologist who focuses on the identification and assessment of natural resources and the creation of natural upland and wetland habitats. He is also involved in nature education, having helped design the nature walk and Butterfly House at Ladew Gardens and the Accessible Trail at Cromwell Valley Park, and has taught “Introduction of Birdwatching” classes for Johns Hopkins Odyssey Program, Community College of Baltimore County, and Cromwell Valley Park. John also writes a monthly Nature Notes column for the Baltimore County Country Chronicle newspaper. He is a member of the Harford Bird Club and the Harford County Land Trust and is on the board of Trustees for Ladew Topiary Gardens.

    Everything has its time, especially when it comes to nature. Phenology is the study of how time and seasonal change affect plants and animals. To see these changes, observations are collected in one specific area over a period of time. Let’s learn how phenology can give your routine walk in your favorite park a purpose.

    We will begin our trip with an indoor presentation given by our leader, Clare Walker, who will teach us the process of what to look for and how to collect and document our observations. We will then practice our observational skills on a short hike. Participants will also learn about the USA National Phenology Network and how one can earn a certification as a local phenology leader to assist with citizen science projects. Phenologists favor using the Nature’s Notebook application, which focuses on long-term monitoring, data collection, and community engagement for science and management.

    Clare Walker teaches plant and pollinator identification and classes on natural basketry and more around Maryland, including programs at Nature Forward, the US Botanical Gardens, and Irvine Nature Center. She delights in native plants and especially their relationships to wildlife and people. Her classes encourage us to cherish our local plants, whether through basketry using natural materials, making herbal remedies, enjoying foods from foraged plants, or gardening with natives. Clare previously worked as a naturalist for Maryland State Parks and then as an environmental outreach specialist for the Maryland Department of Natural Resources.

  • Beavers, Maryland's Master Engineers

    • 22 Mar 2026
    • 4:00 PM - 7:30 PM
    • Forest Hill, Maryland, Near Bel Air

    Join waitlist

    Let’s experience the Maryland landscape through the eyes of its most influential engineer, the American beaver. We’ll begin our deep dive into beaver life and their ecological brilliance with a mini workshop at a local home. We’ll start with the history of beavers in the Mid-Atlantic and move on to explore their unique physiology and unrivaled ability to restore biodiversity and water quality. We’ll learn why these creatures are the keystone of our environment and how we can coexist with them to create a more resilient future.

    As the afternoon sun sets, we will carpool to a nearby active beaver pond. This is where the classroom meets the wild. We will quietly enter the beaver’s realm, observing their dams, lodges, and canals firsthand. If we are still and patient, we may catch a glimpse of the colony members as they emerge at dusk to begin their nightly work.

    To increase our chances of spotting animals and minimize our disturbance, we must arrive prepared and respectful of their heightened senses. Please note these two requirements for attendance.

    • Bring knee-high mud boots to ensure you can comfortably navigate the pond’s edge and soggy terrain.
    • Arrive scent-neutral. Beavers possess an extraordinary sense of smell—it is their primary way of sensing the world around them. Please refrain from using hair products, perfumes, colognes, or strongly scented lotions on the day of the workshop. By arriving scent-neutral, we become invisible guests in their home.

    Our trip leader, Scott McGill, is a professional ecologist with over three decades of experience in nature-based restoration. Scott is the founder of Ecotone, an award-winning ecological firm, and serves on the board of the Beaver Institute. His passion for beaver-mediated restoration is matched only by his deep knowledge of the local landscape.

  • Jelly Fungi and Lookalikes

    • 26 Mar 2026
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    From translucent blobs to coral-like clusters, jelly fungi are among the most visually striking and biologically fascinating organisms found on Maryland’s forest floor. These gelatinous decomposers come in a spectrum of colors—bright orange, inky black, creamy white—and textures that range from rubbery cushions to toothy caps. Often mistaken for slime molds or cup fungi, jelly fungi play a vital role in breaking down dead wood and recycling nutrients in forest ecosystems. Their fruiting bodies emerge under specific moisture and temperature conditions, and their spore dispersal mechanisms are as diverse as their forms.

    In this talk, William Needham—Master Naturalist and former president of the Mycological Association of Washington—will guide us through the science and folklore of these squishy wonders. Topics include:

    • Taxonomy and classification of jelly fungi
    • Spore dispersal and fruiting body development
    • Common Maryland species: white, orange, black, and branching forms
    • Auricularia auricula-judae: culinary uses and nutritional value
    • Witches’ Butter: field uses and cultural superstitions
    • Cup fungi and slime molds that mimic jelly textures

    Whether you’re a curious hiker, amateur mycologist, forager or nature educator, this presentation will deepen your understanding of these organisms and help you distinguish them from their lookalikes in the field.

    William Needham is the former president of the Mycological Association of Washington with extensive field and practical experience with fungi. He is also a Master Naturalist in Maryland. He is active with several hiking and nature groups in the area and writes and co-edits hiking guides for the Potomac Appalachian Trail Club. He co-edited Hikes in the Washington Area, Part A, which includes Montgomery and Frederick Counties. His recently published book, The Compleat Ambler, is based in part on the blog Hiker’s Notebook, which was originally hosted on the Sierra Club Potomac Regional Outings website.

    William, like most of the people who lead NHSM field trips, is a volunteer.

    Horn Point is the first stop in our two-field trip series following the life of an oyster: from spat in a tank, to juveniles in a garden, and finally, to a home in the Chesapeake Bay.
    As the largest hatchery on the East Coast, the Horn Point Lab Oyster Hatchery produces millions of baby oysters each year. We’ll get a behind-the-scenes look at the remarkable process of oyster production. From broodstock conditioning and spawning to larval rearing and algae cultivation, we will see every stage involved in raising oysters from start to finish.
    We will tour the Aquaculture and Restoration Ecology Laboratory. This state-of-the-art facility has greatly expanded the capacity for oyster production and provided quarantine and controlled-environment facilities needed to advance oyster culture and disease research. The hatchery produces a variety of oyster larvae for use in oyster research, oyster restoration, and educational projects. Over the past decade, spawning oysters at the Horn Point Lab Oyster Hatchery has resulted in the deployment of over one billion oyster spat to the waters of the Chesapeake Bay in the hopes of slowing the Chesapeake Bay oyster decline and restoring the health of the Bay. The Horn Point Oyster Hatchery is part of the University of Maryland Center for Environmental Science.

    Explore the transformed farmland of the historic Spocott Farm, now hosting many species of seasonal birds in its restored meadows & buffer zones. We will tour the site with owner George M. Radcliffe, Jr., the seventh grandson of the Radcliffe family who settled here in Dorchester County in 1663. We’ll learn about their restoration efforts, including 30 acres of Conservation Reserve Enhancement Program strips along its waterways and the creation of a 49-acre warm-season grass meadow managed for bobwhite, Eastern meadowlark, Dickcissel, and grasshopper and field sparrows. We’ll be on the lookout for nesting bald eagles, red-tailed hawks, and a rookery of great blue herons.

    We will meet up at the village area to learn about the farm’s 400-year old history, including its windmill, store, and one-room schoolhouse, before carpooling out to the property, spotting birds along the way. Rising sea levels are a concern for the property, and we’ll learn about how it affects the farm and the surrounding areas.

    If you would like to explore more on the Eastern Shore that weekend, join us on Friday as we tour the nearby Horn Point Laboratory Oyster Hatchery on Friday, March 27. Register here: https://marylandnature.wildapricot.org/event-6535392

    Join the Natural History Society of Maryland for a special Founders Day tribute honoring Romeo Mansueti (1923–1963) — one of our own whose scientific legacy continues to shape Chesapeake Bay research today.

    Mansueti’s journey began here as a Junior Naturalist, carried him through years of service as NHSM Curator, and led to pioneering research on fish early life history at the Chesapeake Biological Laboratory. Though his life was cut short at age forty, his work laid foundational ground for future generations of Bay scientists.

    We are honored to welcome Dr. David Secor, Distinguished Professor of Marine Sciences and longtime fisheries biologist at the University of Maryland Center for Environmental Science Chesapeake Biological Laboratory, as our featured speaker. Dr. Secor, a noted expert on fish migration and life history, has continued the research legacy Mansueti began and will share insights into Mansueti’s lasting impact on Bay science and fisheries biology.

    Amy Young, NHSM’s junior historian and author of the forthcoming centennial history of the Society, will share stories and archival details from Mansueti’s years at NHSM. NOTE: If you have any materials, memorabilia, or information about Romeo to share, please email nhsm@marylandnature.org to get in touch with Amy.

    And it wouldn’t be NHSM Founders’ Day without cake!

    Discover how a young naturalist’s curiosity became a scientific tradition that still influences research today.

    • Doors open at 3:45pm. Program will begin at 4:15pm.
    • Free for members, but please RSVP for planning purposes.

    Join the buffet line for newly sprouted delicacies with master forager Nick Spero. Discover locally found plants that can add flavor to your cooking and apply that know-how to your own backyard. We’ll be on the lookout for early springtime plants such as garlic mustard, poke, wild garlic, and perilla. We will discuss collection methods and how to prepare our findings for optimal taste and nutrition. To limit our impact on the park, let’s concentrate on learning to identify and sample taste rather than foraging, which may damage an area when too much is taken.

    Our field trip leader, Nick Spero, spends his retirement outdoors as an avid gatherer, hunter, and fisherman. Primitive technology has piqued his interest since childhood. Nick was featured in an NPR video here.

    Did you get to attend one of our fossil hunting trips this past winter or did you go on your own adventure to find fossils? If the answer is Yes then this is the meeting for you!

    Come share your fossil discoveries, stories from the field, and all the trials and triumphs that went along with the hunt. Whether you traveled far or explored close to home, we’d love to hear about it. Bring your fossils (or photos of them), and if you’re not sure what you found, this is a great chance to get help with identification from fellow club members. We will have the projector set up so you can show photos you may have taken and share them. This will be a great opportunity to meet club members and see what we’re all about, and get ideas for your next fossil hunting adventure.

    This will be an in-person meeting as members will be bringing in fossils they have collected to show attendees, we hope you come and share your recent fossil finds.

    Here are a couple of exciting fossil trips you’ll get to hear about at the meeting:

    • Melissa Madsen’s trips to Lyme Regis, United Kingdom

    • Marla Aron’s fossil adventure in Morocco

    NHSM’s Fossil Club is a group of novice and more experienced collectors who meet to share knowledge and discuss fossil identification, fossil locations, and other fossil-related topics. Monthly meetings feature guest speakers both from within the club and from outside organizations. We also strive to schedule frequent collection trips to various locations. 

    Although you don’t need to be a member to attend a meeting, membership gives you access to additional experiences. An annual NHSM membership is $35 for individuals, $50 for families; Fossil Club membership is an additional $5 for individuals and $10 for families.

    NOTE: THIS TRIP WILL MEET EARLIER THAN USUAL —  815 AM CHECK IN AT STRATFORD.

    How big is your shark tooth collection? If your answer is between zero and a thousand, join us to search for fossil treasures at Stratford Hall. With private beach access and help from expert volunteers, this trip is a unique opportunity for those looking to learn about ancient life in this area and perfect their fossil-collecting techniques.

    Stratford Hall’s cliffs are part of a series of rock layers formed when ancient seas covered the area. Today, the Chesapeake Bay and rivers like the Potomac erode these old sea floor deposits, giving us a window into the past. These cliffs date from about 8 to 16 million years ago, during the Miocene Epoch. This location is one of the most scientifically important exposures of its kind in the Mid-Atlantic region and the world.

    Fossils that could be found include shark teeth from several different species, including Hemipristis or snaggletooth shark, tiger and tiger-like sharks, sand tiger sharks, C. Hastalis or the ancient white shark, and requiem sharks, and shells such as Chesapecten scallop and the Maryland state fossil, Ecphora, a predatory snail. Bones from whales and dolphin-like marine mammals, turtle shell pieces, sting ray dental plates and barbs, crocodile teeth, and fossilized crabs are also possibilities.

    This site is part of the Stratford Hall plantation owned by four generations of the Lee family and is now managed by the Robert E. Lee Memorial Foundation. The estate encompasses 1900 acres of farmland and forests on a high bluff overlooking the Potomac River. Field trip participants have access to tour the estate while at the fossil hunt.

    Travel time: It is an estimated three-hour drive from Baltimore to Montross, VA (on the south side of the Potomac River, adjacent to Westmoreland State Park). Guests are responsible for their own transportation. Many choose to spend the night before or after to break up the drive. Hotels can be found in the towns of King George and Colonial Beach.

    Difficulty: This field trip is moderately strenuous, involving hiking, cold water, and uncertain weather. There will be washed-up trees and debris on the beach that will result in scramble spots. If you do not want to climb over obstacles, you can remain on the beach that is accessible to you. However, please note that you will be wading in the water, and in colder months, we recommend wearing waders. Bare feet are never allowed. This is a rain-or-shine event.

    Age Restriction: The minimum age requirement is eight years old. This age limit is set by Stratford, and there are no exceptions. Please respect this policy when registering your family.

    • 6908 Belair Rd, Natural History Society of MD
    Register

    Each spring, as snowmelt and seasonal rains gather in shallow forest depressions, a hidden world awakens. Vernal pools, temporary wetlands that appear and vanish with the seasons, become vibrant nurseries for some of Maryland’s most fascinating amphibians and reptiles. This talk explores the ecology, biodiversity, complex food webs, and conservation importance of vernal pools in Maryland. Though they may look like simple woodland puddles, these fish-free waters are critical breeding and feeding habitats for species that depend on their brief existence.  For those of you who may have gone on a vernal pool trip or will be soon, this will be a great opportunity to learn more about these unique environments.

    We’ll take a closer look at native amphibians such as:

    • Spotted salamander
    • Four-toed salamanders
    • Marbled salamander
    • Newts
    • Frogs

    This in-person presentation will feature striking images taken by Mark Tegges at vernal pools local to the central Maryland region.

    Mark Tegges was born and raised in Baltimore City. Since childhood, he has been interested in reptiles and amphibians. While growing up in Baltimore, he attended Polytech High School, where he became an active member of the herpetology club, building camaraderie through sharing his appreciation of reptiles with his classmates. While attending Towson State University, he continued to study herps. Mark has been photographing reptiles and amphibians since he was 14, and this passion has taken him all over the world to document these remarkable creatures.

    This presentation will be in person at the Natural History Society of Maryland building at the following address:

    6908 Belair Rd.
    Overlea, MD 21206

    Are you fascinated by reptiles and amphibians? The Natural History Society of Maryland’s Herp Club promotes the proper husbandry, conservation, study, and appreciation of reptiles and amphibians. Amateurs, professionals, and kids of all ages are welcome. Meetings are held on the second Wednesday of every month and are open to the public.

    • 2
    Register

    Digging holes seems like child’s play. But not when you’re the crew at Martin Marietta’s Texas Quarry. Their hole isn’t measured in feet, but rather miles: a mile long and a half mile wide, to be exact. This massive pit was the source of marble that was used to build the walkway to the Capitol in Annapolis and the portico for St. Paul’s Cathedral in NYC. Our Washington Monument in Baltimore and a section of the Washington Monument in D.C. are also made from Texas marble. The history of this quarry goes back even further to 1802 and the first Irish immigrants to the region. On this tour, let’s watch the heavy equipment dig and haul while discovering the stories of those immigrants.

    We will learn the history of the quarry, including past and current ownership, and information on daily operations. This tour is based on a scenic overlook above the quarry. From there, we can view the equipment at work in the distance. There is no public access to the quarry pit or the operations since it is a working job site. The crew is working about a mile away — binoculars are recommended for closer viewing.

    Please note

    • Our meeting location can be found in your registration confirmation email when payment is complete.
    • Watch for additional details in a welcome email a few days before the date.
    • When you arrive, all must sign a Hold Harmless Agreement with Martin Marietta to be on the property.
    • Everyone aged 5 years and older is welcome to attend.
    • Proper outdoor etiquette is required. No climbing, running, or loud voices. Be respectful of our speakers by demonstrating good listening skills.
    • Families are welcome to leave the tour at any time if needed.
    • Photos are welcome.
    • Bring binoculars to see the trucks working across the pit. It is over a mile wide.
    • Picnic tables are available for seating. You may bring lawn chairs.
    • There is no walking except from the parking lot to the viewpoint. No one has access to the interior of the operation except personnel.

    In case of inclement weather, this tour may be canceled by Martin-Marietta, and you will be notified by NHSM. If you do not receive a weather-related email, the trip will proceed as planned.

    Martin-Marietta offers this trip for groups only, not individuals. Please consider our registration fees as a donation to NHSM to cover administrative costs.

  • The Chesapeake Bay Impact and Other Tales from my Life as a Paleontologist

    • 09 Apr 2026
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    After 40 years as a paleontologist, Dr. Lucy E. Edwards retired from the U.S. Geological Survey. Lucy attributes her success to a combination of being in the right place at the right time, a lot of hard work, and a brain that just happened to be wired to think like a paleontologist.

    The fossils she studies are the cysts of dinoflagellates – a type of algae, small, wax-like hydrocarbon structures that are neither plant nor animal – which are most often found in nearshore muddy deposits. They help determine the age and environment of ancient deposits, often as part of groundwater studies.

    The work involved a fair amount of time “sitting on a drill rig,” and much more time looking at the dinoflagellate cysts brought up in the sediments. In all that looking, Lucy has named several new species and one new genus; and has had several species and one genus named after her.

    The highlight of Dr. Edward’s career was her involvement in the discovery and decades-long study of the Chesapeake Bay impact structure, which was formed 35.5 million years ago in what was then a shallow part of the Atlantic Ocean. The fossils in and around the now-buried crater were first a mystery to her and then a series of logical consequences of the massive impact.

    In this presentation, Lucy will share additional vignettes on how to interest others in science, other impact areas and craters, and what else dinocysts can tell us.
     
    Lucy E. Edwards focuses her research on the stratigraphy of the Atlantic and Gulf Coastal Plains. Her specialty is dinoflagellates, and she studies their fossil cysts to reveal the time and environment of deposition and how they came to be preserved in the fossil record. She also specializes in stratigraphic nomenclature and methods of stratigraphic correlation. She received her BA (Honors College) in Geology from the University of Oregon in 1972 and her PhD in Geological Sciences from the University of California, Riverside, in 1977. She has taught courses at George Washington University, Indiana University, University of Kansas, University of Oslo, George Mason University, and Türkiye Petrolleri AO. She is a fellow of the American Association for the Advancement of Science, the Geological Society of America, and the Paleontological Society. As a graduate student, she worked two summers for Exxon Production Research Co. in Houston.

    Register

    People always have been interested in snakes, turtles, lizards, and alligators, as well as frogs and salamanders. Amphibians and reptiles—collectively known as herpetofauna—are increasingly important today as their populations are key indicators of the effects of climate change and habitat fragmentation on wildlife. Presented by certified merit badge counselor, Tom Scollins, herpetology curator and leader of NHSM Herp Club, this class will help you fulfill the following Merit Badge requirements*: 1,2,3,4,5,6,7,10. There will be plenty of live and preserved animals on hand.

    Things to remember to bring for this Merit Badge Class:

    1. Merit Badge Blue Card properly filled out and signed off by your Scoutmaster
    2. Scout Uniform
    3. Supporting documentation or project work pertinent to this merit badge which may also include a Merit Badge Workbook for reference with notes
    4. A positive Scouting focus and attitude

    Pre-Requisite: Read the booklet before class.

    The badge also requires either three months of recorded observation of a reptile or Amphibian in a nature center, zoo or similar location, OR one month care and recorded observations of a reptile or amphibian you keep at home. If you have a pet reptile or amphibian already, then the one month of care is a simple option for you. PLEASE do NOT go out and purchase a pet reptile or amphibian just to complete the badge! Pet ownership is always a long-term commitment for the life of your pet and should only be undertaken after careful consideration. You may make observations at any a nature center, zoo, pet store, or other similar center near your home.

    NOTE: The Mid-Atlantic Turtle and Tortoise Society is partnering with NHSM on this badge, and will make available foster turtles for purposes of fulfilling the merit badge requirements. You may convert the fostering into adoption. 

    Families can foster an adult box turtle in a Rubbermaid tote or a juvenile aquatic turtle such as a slider, in a 10- or 20-gallon aquarium.
    Anyone who wishes to foster, please  email matts_adoptions@hotmail.com as soon as possible to receive recommended reading and an application, to know what to expect or to find out which type of turtle they’d prefer, and to  set up enclosures to go with the turtles.  A refundable $50 deposit is required when fosters pick up the turtle and supplies. The deposit will be returned when the turtle and supplies are returned.
    NEW Payment and Cancellation Policy: Payment is due online at the time of registration. Cancellations made 14 or more days in advance of the event will receive a refund minus a 5% processing fee. Cancellations made within 14 days of the event will not receive a refund. Events and field trips with fees of $25 or less are non-refundable at any time unless canceled by NHSM. NHSM retains the right to update or change these requirements at any time.

    * Most Merit Badges are not designed to be completed in a single session with an instructor, so it is not always possible to walk away with a completed and signed blue card at the end a program. Every badge requires some independent work by your scout. We call this “pre-work” because, if these requirements are performed prior to our program, we can complete and sign the merit badge card. Otherwise we will sign partial cards at the completion of our program and will have qualified counselors review assignments on an individual basis at a later date. Note you will have to contact and schedule an appointment with Tom Scollins. NOTE: The Herp club meets monthly at NHSM on the Second Wednesday of every month at 7PM. 

    The Natural History Society of Maryland is a volunteer-led non-profit organization, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible.

    April is Maryland Archeology Month! This year’s theme is  250 Years, Many Voices: Digging into Maryland’s Story. To go along with the theme this months Archaeology club meeting will be a presentation from Stephanie Soder a Research Archaeologist for the Maryland Historical Trust on the Washington-Rochambeau Military Encampments from the Revolutionary war.

    In the fall of 1781, French and American troops marched south to besiege the entrenched British forces at Yorktown, Virginia. By late summer 1782, they made their way north in victory. The Maryland Historical Trust (MHT), with funding from the American Battlefield Protection Program, is currently undertaking a survey to identify and document the understudied encampment sites and cultural resources associated with these marches in Cecil and Harford Counties. This presentation will provide historical background on the troop movement, a crash course in the types of geophysical surveys MHT has used to study these sites, and the preliminary results of the surveys conducted.
    Stephanie Soder is the Research Archaeologist for the Maryland Historical Trust. She received her Master’s degree in Maritime Studies (Archaeology) at East Carolina University and has experience working on both terrestrial and underwater sites. Her interests include conflict archaeology, maritime history, public archaeology, and geophysical survey techniques. She and other archaeologists at the Office of Archaeology are responsible for researching, documenting, and preserving archaeological sites across the state.

    This meeting of the NHSM Archaeology Club will take place on Zoom. In order to receive the Zoom link you need to register. It is free and open to the public, although non-members are asked to please donate $5 to support the club.

    When you register for the program, you’ll receive the Zoom link and passcode via email with your registration confirmation. Please contact the community coordinator (rbaldwin@marylandnature.org) with any questions.

    NHSM’s Archaeology Club was founded in 2019 to promote the value of archaeology in Baltimore City, Baltimore County, and surrounding areas.

    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Plant-eating plants, or parasitic plants, are among the most misunderstood and fascinating members of the plant kingdom. In this presentation, Dr. Vanessa Beauchamp of Towson University introduces the remarkable diversity of plants that survive by tapping directly into other organisms for resources. This talk will explore how parasitic plants live and how they locate and establish connections with their hosts. Drawing on examples from forests, fields, and local Maryland landscapes, this talk examines what it truly means for a plant to be parasitic and how these hidden relationships influence ecosystems. From dramatic dodders to stealthy root parasites, attendees will gain a new perspective on plant interactions that usually go unseen.

    Dr. Vanessa Beauchamp is a professor in the Department of Biological Sciences at Towson University. She earned her BS in Biology from the University of California, Irvine, and her PhD in Plant Biology from Arizona State University. Her research interests focus on plant community ecology, particularly the effects of invasive plant species on community diversity and successional processes. She also works on projects related to forest and stream restoration and the impact of deer on local forests. A significant portion of her research program addresses practical applications concerning the management, conservation, and restoration of plant communities.

    Nature Connections is back! Be a part of our first Nature Connections since the building renovation! 

    Hawks, osprey, eagles, falcons, owls, kites, and vultures, are all amazing birds of prey that we call raptors! What is a raptor you ask? Hooked beaks, grasping talons, a purely carnivorous diet, and keen eyes define them as a group…it’s not hard to imagine that they descended from dinosaurs. Join us at the museum to visit with live birds with their handlers from rescue organizations, use binoculars and scopes for outdoor viewing with some of our expert birders, see historic taxidermy from our collections, learn to identify raptors through sights and sounds, and play games and do crafts to learn more about these amazing birds with our educators.

    Presentation, 3:00pm: The Farmland Raptors Program by Alex Pellegrini.  Alex will speak about the Maryland Bird Conservation’s Farmland Raptor Program, what they have learned about farmland raptors, how raptors can help farmers, and what people can do to help their declining populations. He may also share some of his experiences working with raptors of all kinds!

    The program is free, but for planning purposes, we ask that you RSVP.

    ABOUT NATURE CONNECTIONS: Nature Connections is a signature program offered to you by the Natural History Society of Maryland with financial support from the Citizens of Baltimore County.

  • Freshwater Bivalves of Maryland

    • 23 Apr 2026
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Maryland is home to at least sixteen native species of freshwater mussels, though that number continues to shift as taxonomic work refines our understanding. These species occur statewide in a wide range of aquatic habitats, and identification can be challenging. Key features often lie inside the shell, and many species show significant variation in shape and appearance. Maryland has also gained two additional species from the Ohio River basin through the movement of host fish carrying mussel larvae.

    In this talk, Matt Ashton, manager of the Freshwater Mussel Assessment Program at the Maryland Department of Natural Resources, will introduce the freshwater mussels of Maryland. We’ll learn what they look like, how to tell them apart, and where they live. Matt has surveyed and monitored mussels across the state since 2007, supporting conservation, habitat restoration, and captive propagation efforts. He brings prior experience working with mussel communities in the Southeast and Midwest.

  • Fossil Club Trip to Centralia, PA

    • 25 Apr 2026
    • 10:00 AM - 3:30 PM
    • Centralia
    • 20

    NHSM Fossil Club members are once again invited to Centralia, PA, to hunt for plant fossils. Centralia was a small coal mining community in central PA that had to be abandoned after the coal beds under it caught fire in the 1960s. Today nothing is left but the streets and sidewalks and some cemeteries. The surrounding area has several strip mines with numerous plant fossils. These are typical Llewelyn formation fossils, some of which are coated with pyrophyllite like the famous St. Clair fern fossils. In addition to fern foliage and seeds, there are also lepidodendron (scale tree) fossils including roots, stems, foliage, and cones.

    Preservation and detail is good. Collecting is typical for plant fossils, splitting relatively soft shale with a hammer and chisel. There will be a half mile walk from the parking area to the collecting area. The terrain is very steep in places with rock faces of 20 to 40 feet and collecting in the scree at the bottom, so a degree of fitness and comfort moving around loose rock is required.

    There are no facilities at the site. In nearby Ashland, PA there is also the Pioneer Tunnel, a drift coal mine that offers underground tours. For questions contact Tom Farrell (33tomfarrell@gmail.com) and/or the community coordinator (rbaldwin@marylandnature.org).

    Details about time and meeting location will be shared with registrants via email before the trip. You must be a current member of the NHSM Fossil Club to sign up for this trip.

    NHSM’s Fossil Club is a group of novice and more experienced collectors who meet to share knowledge and discuss fossil identification, fossil locations, and other fossil-related topics. Monthly meetings feature guest speakers both from within the club and from outside organizations. We also strive to schedule frequent collecting trips to various locations.

    An annual NHSM membership is $35 for individuals, $50 for families; Fossil Club membership is an additional $5 for individuals and $10 for families.

    If you are not yet a member of NHSM, click here to join. When you join as a new member, you can add the club membership(s) of your choice to your registration. Current NHSM members who wish to join any clubs should email the Community Coordinator at rbaldwin@marylandnature.org.

    The Natural History Society of Maryland is a volunteer-led non-profit organization, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible. Learn more about NHSM Clubs: https://youtu.be/pIA7naRjXws

    Join waitlist

    If truffles are out of your price range, morels are the next best thing. Prized for taste and versatility by chefs worldwide, morels emerge for only a short time in spring. Knowing where to look for morels is one important factor in the hunt. Lucky for us, Nick Spero knows all the clues. He knows the rich forests where morels grow and how they are intertwined in a symbiotic relationship with certain trees. We’ll learn how indicator plants can tell us when the morel growing season will start and end. And how the right combination of warmth and rain brings morels popping their heads out of the soil.

    We will discuss collection methods and how to prepare our findings for optimal taste and nutrition. To limit our impact on the park, let’s concentrate on learning to identify and sample taste rather than foraging, which may damage an area when too much is taken.

    Please note that morels are very temperature and moisture-dependent. We will do our best to find them, but like all natural things, we make no guarantees.

    Our field trip leader, Nick Spero, spends his retirement outdoors as an avid hunter and fisherman. Primitive technology has piqued his interest since childhood. Here is a video produced by NPR about Nick.

    • 10
    Register

    Despite the urban development surrounding it, Patterson Park’s natural history remains strong, acting as a migrant trap for birds with over 223 species recorded since 2009. We may see many neotropical migrants and some residents, including green heron, black-crowned night heron, green heron, Cooper’s hawk, ovenbird, Northern waterthrush, black-and-white warbler, common yellowthroat, American redstart, Northern parula, Northern yellow warbler, black-throated blue warbler, prairie warbler, rose-breasted grosbeak, and scarlet tanager. The park is ranked among the top 100 hotspots in Maryland, per species, according to eBird.org.

    This vibrant bird community is sustained through the efforts of native tree plantings and existing tree maintenance managed by the Friends of Patterson Park and City Forestry. The Audubon-Baltimore Program also maintains a flourishing native wetland garden through monthly volunteer events.

    Our birding leader, Bud Poole, will share how planting native species of trees and plants in the park sustains and grows the park’s bird diversity. Bud is a nearby resident and frequent birder, with a total of 201 species documented on his park list. He is a dedicated volunteer with the Friends of Patterson Park, Baltimore City Recreation and Parks’ Forestry Division, Phoenix Wildlife Center, and Audubon. Bud’s mission is to help wildlife thrive among the urban landscape while showcasing nature’s beauty and benefits to park goers of Patterson Park.

  • The History of the Earth, Evolution and its Fossils

    • 06 May 2026
    • 7:00 PM - 8:30 PM
    • 6908 Belair Rd, Natural History Society of MD, Online via Zoom
    Register

    The Earth has a long history, and for most of the time has supported life. We will probe the depths of geological time and how life evolved into its current state. Recent advances in microbiology have suggested that eukaryotic cells (those with nuclei) were a logical and even likely outgrowth of evolution in a group of prokaryotic cells (those without nuclei) known as the Asgard Archaea. The Cambrian explosion, while still important, was not the first eukaryotic biodiversity event. We’ll touch on the importance of extinction events in shaping evolutionary pathways. And get an idea of when and how these events took place. There will be a range of fossils displayed to complement the talk.

    This presentation will be hybrid, in person and on Zoom. To receive the Zoom link, you need to register for the meeting. We encourage you to participate in person to get a first-hand experience with fossils.

     Tom Farrell is an amateur fossil collector and a member of the NHSM Fossil Club as well as several other fossil clubs. He is a Maryland Master Naturalist, and his interest in the current world’s biodiversity extends into the deep past and how we got to this point. He has given several NHSM Fossil Club talks before on the fossils of the Pennsylvania anthracite fields and on beginner fossil preparation techniques.

    NHSM’s Fossil Club is a group of novice and more experienced collectors who meet to share knowledge and discuss fossil identification, fossil locations, and other fossil-related topics. Monthly meetings feature guest speakers both from within the club and from outside organizations. We also strive to schedule frequent collection trips to various locations.

  • Biodiversity in Agricultural Drainage Ditches on the Eastern Shore

    • 07 May 2026
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Agricultural drainage ditches are essential for water management on farms with high water tables, including those on the Delmarva Peninsula. These seemingly mundane agricultural infrastructures are home to insect biodiversity that provides valuable ecosystem services,such as pollination, biological control of pests, decomposition of plant and animal matter, and food support for wildlife. In this presentation, we will learn about phosphorous sequestration by tube-dwelling, non-biting midges that help to clean water before it flows downstream, and parasitoid wasps and other arthropods that eradicate nuisance insects. You’ll never look at a ditch in the same way again.

    Dr. Bill Lamp is a Professor of Entomology at the University of Maryland, College Park.  His research is interdisciplinary, applying Integrated pest management practices within sustainable agriculture systems with a focus on forage-based agriculture. Since starting at the University of Maryland in 1985, his research has included plant-insect interactions, aquatic entomology, non-target risk analysis, and biological control. Dr. Lamp has published three books on forage management, and written15 chapters and 76 refereed articles. He has given 65 invited presentations for his research, and received 78 grants, including 24 from USDA (e.g., Sustainable Agricultural Systems, Sustainable Agriculture Research and Education, Alfalfa and Forage Research, and Biotechnology Risk Assessment Program). He has taught Integrated Pest Management, Plant Protection, Biology of Insects, Sustainability, Insect Biodiversity, Freshwater Biology, and Insect Apocalypse: Real or Imagined over the last 40 years and received a Distinguished Teaching Award from the Eastern Branch Entomological Society of America in 2009. He also received Undergraduate Mentor of the Year in 2002 and the Winston Family Honors Faculty Award in 2021 at the University of Maryland. He has advised 12 Master’s and 14 Ph.D. students. He received the Herb T. Streu Meritorious Service Award for the Eastern Branch Entomological Society of America in 2016 and served as President of the Eastern Branch in 2021-22. During his presidency, he created EntoQuest, an annual meeting focused on informal interactions among students and ESA members in a natural setting, now held four times. Finally, he has served as science editor for 16 National Geographic Kids books.

    Join us for an evening sail on The Lady Maryland. Here is your chance to learn a bit about sailing as well as engage in hands-on marine science from our friends at the Living Classroom Foundation. Activities will include water quality testing, plankton trawling with microscope exploration, trawl fishing for marine life, oyster dissection, birding, setting sail, steering the ship, and local history, too. Bring a light dinner and beverage: alcohol is allowed, too.

    The Lady Maryland is a replica of a pungy schooner, originally built in Maryland and Virginia between 1840 and 1880. Pungies were a significant development in vessel design, uniquely adapted for carrying perishable cargo on the Chesapeake Bay. Pungies have a hull shape similar to the famous Baltimore Clippers, making them extremely fast, an important asset when delivering cargo. The Lady Maryland was built in 1986 to provide a hands-on opportunity to sail a historic vessel and learn about the ecology, history, and economics of the Bay.

    Our time will be spent touring the Inner Harbor and Fort McHenry. In addition to the science, the crew is very knowledgeable about Baltimore sights and local history, and they love to share stories with guests.
    • Ages 18 and up

    Register

    Since the 1940s, scientists have tracked Eastern box turtles at the Patuxent Research Refuge as part of one of the longest-running wildlife surveys in the U.S. This research reveals their movements, survival strategies, and use of habitats. With box turtle populations in steep decline due to habitat destruction, road mortality, and illegal trafficking, information gathered can help researchers work toward solutions.

    Join us to learn about this project and its findings with an overview from Dr. Andy Royle, senior scientist at the Eastern Ecological Science Center. We’ll then head outdoors to search for turtles in the nearby woods. We’ll be hiking about two miles at an easy pace with plenty of stops. May is peak turtle season, so we should be able to sight turtles. We may also meet a captive turtle at the building, too.

    In 2019, Dr. Royle launched the Quantitative Turtle Analysis Project to overcome some of the challenges related to mark-recapture-capture methods. The project investigates how digital images can be used by automated programs to recognize unique individual turtles in place of marking systems like scute notching, and how uncertain individual identifications can be used in capture-recapture methods.  He has authored or coauthored six books on quantitative analysis in ecology, including the recent book, Applied Hierarchical Models, Vols. 1 and 2.

    Join waitlist

    How big is your shark tooth collection? If your answer is between zero and a thousand, join us to search for fossil treasures at Stratford Hall. With private beach access and help from expert volunteers, this trip is a unique opportunity for those looking to learn about ancient life in this area and perfect their fossil-collecting techniques.

    Stratford Hall’s cliffs are part of a series of rock layers formed when ancient seas covered the area. Today, the Chesapeake Bay and rivers like the Potomac erode these old sea floor deposits, giving us a window into the past. These cliffs date from about 8 to 16 million years ago, during the Miocene Epoch. This location is one of the most scientifically important exposures of its kind in the Mid-Atlantic region and the world.

    Fossils that could be found include shark teeth from several different species, including Hemipristis or snaggletooth shark, tiger and tiger-like sharks, sand tiger sharks, C. Hastalis or the ancient white shark, and requiem sharks, and shells such as Chesapecten scallop and the Maryland state fossil, Ecphora, a predatory snail. Bones from whales and dolphin-like marine mammals, turtle shell pieces, sting ray dental plates and barbs, crocodile teeth, and fossilized crabs are also possibilities.

    This site is part of the Stratford Hall plantation owned by four generations of the Lee family and is now managed by the Robert E. Lee Memorial Foundation. The estate encompasses 1900 acres of farmland and forests on a high bluff overlooking the Potomac River. Field trip participants have access to tour the estate while at the fossil hunt.

    Travel time: It is an estimated three-hour drive from Baltimore to Montross, VA (on the south side of the Potomac River, adjacent to Westmoreland State Park). Guests are responsible for their own transportation. Many choose to spend the night before or after to break up the drive. Hotels can be found in the towns of King George and Colonial Beach.

    Difficulty: This field trip is moderately strenuous, involving hiking, cold water, and uncertain weather. There will be washed-up trees and debris on the beach that will result in scramble spots. If you do not want to climb over obstacles, you can remain on the beach that is accessible to you. However, please note that you will be wading in the water, and in colder months, we recommend wearing waders. Bare feet are never allowed. This is a rain-or-shine event.

  • May Lep Club: Carnivorous Butterflies? Unexpected food sources for unlikely predators.

    • 27 May 2026
    • 7:00 PM - 8:30 PM
    • 6908 Belair Rd, Natural History Society of MD, Online via Zoom
    Register

    Did you know that there are some caterpillars that don’t eat plants for food?

    There are numerous butterfly species worldwide that eat other insect larvae or nymphs as their food source during their developmental stages and there are even some species that live here in Maryland. These are primarily members of the Lycaenidae family (Hairstreaks and Blues) and these have very specific relationships with certain ants and with one species consuming wooly aphids.  This lecture will examine the relationship, with specific examples, of different butterfly species with their host ants and explain the reasons of how this is possible as well as their delicate balance of existence.

    Fred Paraskevoudakis (Paras) is a Professor at Baltimore City Community College where he has taught microbiology, as well as biotechnology and environmental science, since 1992. His passion for insects (and natural history) began as a kid growing up in Puerto Rico and has continued to this day. He is the President of the Maryland Entomological Society and the Curator of Shells for the NHSM. He has travelled all over the world, as well as the United States, in pursuit of insects and his other passions of shells, minerals and fossils.

    This will be a Hybrid meeting in person and on Zoom. To receive the zoom link you must register. We encourage you to attend in person to see specimens of the butterflies that will be discussed.

    If you love butterflies and moths, consider joining the NHSM Lep Club. Made up of novice and expert lepidopterists who meet to exchange knowledge and support concerning habitat, threats, food sources, identification, and life cycle of butterflies and moths, the Lep Club encourages the sharing of knowledge for the raising and breeding of moths and butterflies through hands-on lessons and guest speakers.

    The NHSM Lepidoptera Club meets the fourth Wednesday of every month from March-October at 6908 Belair Rd or over Zoom. Club members are also involved in outreach in the greater Baltimore community through educational programs and service projects. If you have questions feel free to email the club coordinator at rbaldwin@marylandnature.org

    Annual NHSM membership is $35 for individuals, $50 for families; Lep Club membership is an additional $5 for individuals and $10 for families. Although you don’t need to be a member to attend our meetings, your membership dues support our programs and give you access to exclusive field trips and other events.

  • What Trees Remember: Climate, Water, and Change in Western Maryland

    • 28 May 2026
    • 7:00 PM - 8:00 PM
    • Online via Zoom
    Register

    Trees are invaluable record-keepers of the past. Since their annual growth is intrinsically related to a combination of environmental factors, tree ring data can be used like a Rosetta Stone. Dr. Karen King will demonstrate how her research in biogeography and climate change is informed by tree-ring data. We will focus on regional examples from western Maryland to learn what tree rings can tell us about temperature, hydroclimate, and ecological variability.

    Dr. Karen King, an assistant professor at the University of Tennessee, Knoxville, runs the Tree Ring Lab in the Department of Geography and Sustainability. She holds both a BS and an MS from Frostburg State University and a PhD from the University of Idaho. As a biogeographer, Karen’s research interests focus on Quaternary landscape dynamics and paleoenvironmental reconstruction from intra-annual to multi-century time scales. She uses dendrochronology and spatial analysis as research tools to investigate landscape‐scale dynamics. Her research integrates present‐day climatic and ecological processes with those that functioned in the past and those that are likely to be altered in the near future due to human‐induced changes.

  • Fossil Club: Asaphid Trilobites from the Western United States, an Exceptional Window into Past Ontogenies

    • 02 Sep 2026
    • 7:00 PM - 8:30 PM
    • Online via Zoom
    Register

    The trilobite family Asaphidae represents a significant part of the taxonomic diversity of the Lower Ordovician in the Great Basin region of the western Laurentia (North American Craton) in the United States. These arthropods are notoriously known for being difficult to study due to their convergent, smooth, and effaced morphology. The trilobites of the Great Basin region, however, have been exceptionally preserved through silicification. This mode of fossilization allows us to recover 3D replicas of the original shell of the animal, preserving all of the exquisite details of the morphology. Silicification also preserves ontogenetic stages, from the smallest larvae to the adult. This exceptional material allows us an extraordinary window into the early evolution of this group, as well as abundant data on the developmental biology of arthropods from 480 million years ago.

    Titouan Camus is a PhD candidate from the University of Iowa, working on Asaphid trilobites since 2024. After earning a bachelor’s in Biology and Geology at the University of Western Brittany in France, he obtained a master’s in Paleobiology from the Universities of Uppsala (Sweden) and Lille (France). His research focuses on the early evolution of Laurentian Asaphid trilobites from Utah and Idaho, with a particular interest in the relationship between ontogeny and phylogeny.

    This meeting will take place over Zoom. To receive the Zoom link, you must register for the meeting.

    NHSM’s Fossil Club is a group of novice and more experienced collectors who meet to share knowledge and discuss fossil identification, fossil locations, and other fossil-related topics. Monthly meetings feature guest speakers both from within the club and from outside organizations. We also strive to schedule frequent collection trips to various locations. 

    Although you don’t need to be a member to attend a meeting, membership gives you access to additional experiences. An annual NHSM membership is $35 for individuals, $50 for families; Fossil Club membership is an additional $5 for individuals and $10 for families.

    Let’s explore the natural sciences beyond the usual tourist stops to experience the whole island of Puerto Rico from coast to coast. This active trip highlights the lesser-known spots as well as offers unique interactions with its endemic flora and fauna. We’ll hike the karst region to explore caves, look for a 1000-year-old tree in the Guánica Dry Forest, and admire a nursery full of young coral and sea urchins. There’s a stop to learn about leatherback turtles and a chance to see turtles in the wild on a snorkel trip in the mangroves. Along the way, we’ll meet park rangers and research scientists who are making a difference every day in protecting the biodiversity of Puerto Rico. Don’t worry, we’ll enjoy the ever-popular El Yunque National Forest on an all-day bird adventure to search for those endemics, too.

    • Small group travel: No more than eight adults will participate, plus two trip leaders.
    • Our itinerary is subject to change. Participants will receive updates before departure.
    • Please note that inclusions, the cancellation policy, and payment terms are described following the itinerary. You may secure your spot today with only a deposit.

    Day 1: Friday, Nov 6

    Welcome to San Juan! Check in to your room any time after 3 pm. Settle in, then let’s get acquainted.

    5 pm – Welcome Meeting at our hotel. We’ll meet up in the front lobby of our hotel for introductions. From there, we’ll walk to dinner as a group.

    Day 2: Saturday, Nov 7

    8:15 am – Meet in the lobby with luggage ready for the van. Remember to check out and pay for any incidentals. Have your day pack ready with any supplies you may need for the day, including your refillable water bottle, snacks, walking shoes, and a lightweight rain jacket.

    We’ll head out for our first stop of the day, a 9 am tour of Old San Juan and the UNESCO World Heritage Site, Castillo San Cristóbal. As the largest Spanish-built fortification in the New World, San Cristóbal was constructed between 1634 and 1783 to defend against land-based attacks. The site covers 27 acres and features complex tunnels, moats, and bastions, protecting the city from English and Dutch invaders. Please note that we will not have enough time to visit its sister fort, El Morro. There may be time on our last day of the tour, or you can add an extended stay to your trip to allow time for a visit on your own.

    We will also wander the streets of Old San Juan to admire the architecture and history that range from native archaeological finds to modern construction.

    Finishing our tour around midday, we’ll grab some lunch, then hit the road for our drive west to the small beach town of Carrizales. We’ll take the scenic route along the ocean, then move inland to experience Cueva Ventana, or Window Cave. We’ll see stalagmites, stalactites, and other cave structures, and we’ll discuss the flora and fauna in this tropical setting. Our walk ends with a picture-window view from the 700-foot-high cliff, gazing out into the forest below.

    After arriving at our hotel for the evening, you are welcome to walk to the beach, a short distance away, and eat dinner at your leisure. Shop for lunch, snacks, and drinks for tomorrow’s hike, too.

    Day 3: Sunday, Nov 8

    7 am – Let’s meet in the lobby with your bag and day pack with lunch, water, and snacks ready for the van. Yesterday’s cave was a bite-sized sampling of today’s adventure. We’re up early to meet our guides and leader, Angel Acosta-Colon, for an all-day hike through the karst hills and valleys to explore four caves in this special section of the island. Breakfast will be at a nearby bakery at your cost.

    The limestone mountains in this region of the island have dissolved over time due to rain and groundwater. This creates a characteristic landscape full of caves, rivers, and springs. We will explore four of these limestone caves as we hike through the karst forest. We will see and learn about cave art created by the Taíno people, view speleothems such as stalactites and stalagmites, and admire a crystal cave. We’ll look for endemic and common plants, trees, and birds along the way, too.

    Our hike will be guided by staff from the Cabachuelas Project, a community-based education and ecotourism project created for the Las Cabachuelas Nature Reserve. Safety equipment provided includes a helmet and flashlight.

    About our Leader: Angel Acosta-Colon works as the Interim Director of the Physics and Chemistry Department at the University of Puerto Rico, Arecibo campus. He has an environmental geophysical background and currently works in the characterization of karst and cave systems in Puerto Rico. His main interest is in LiDAR and photogrammetry applications in geosciences. His projects have been sponsored by the National Science Foundation, NASA, and the EPA.

    After our hike, we’ll relax in the van while we make our way to visit the Museum of Natural History and Conservation of Puerto Rico in Aguadilla. The museum is the first natural history museum in Puerto Rico in more than 100 years and is newly opened. We’ll take a tour with the museum founder and several members of the team, who are all very excited about our visit.

    After the museum, we’ll head to our hotel in Mayagüez, about a 40-minute drive. The hotel is located near the historic center of town, and you are welcome to spend the evening exploring on your own or as a group.

    Day 4: Monday, Nov 9

    8 am – Let’s meet with our gear, ready for a day exploring the coast. We’ll drive about 40 minutes to our first stop, the Institute of Socio-Ecological Research, known as ISER Caribe. This marine nursery, located on a nearby island, focuses on restoring coral reefs through an ecosystem-based approach. It is part of the Center for Research and Restoration of Marine Organisms. We will tour their coral nursery as well as their long-spined sea urchin and Caribbean king crab nurseries to learn how to raise these herbivores, which are released onto reefs to control algae and promote coral health.

    After our time on the island, we’ll have a short drive to our next hotel situated on the Caribbean oceanfront. We’ll settle in for a bit, then grab our snorkeling gear and head to the dock on site. We will take a quick boat ride out to snorkel and explore Gilligan’s Island for the rest of the afternoon. No, this isn’t the set for the ‘60s sit-com, but it is famous for crystal-clear shallow lagoons ideal for snorkeling and for exploring a protected mangrove forest.

    Back at the hotel, you are free to eat dinner, rest, swim, and enjoy the hotel property.

    Day 5: Tuesday, Nov 10

    7:45 am – Today is all about the Guánica Dry Forest. We’ll meet with all our gear and day packs, ready to take a short drive back to town to meet up with our guide. From there, we’ll drive to the trailhead to begin our two-hour hike through the Bosque Seco de Guánica. This 10,000-acre forest tract was designated as a United Nations International Biosphere Reserve in 1981 and is both the best preserved subtropical dry forest and the best example of dry forest in the Caribbean.

    Our hiking destination is to view the Guayacán Centenario, an old-growth guaiacwood tree, estimated to be 1,000 years old. In addition to this historic tree, other plants, animals, and birds thrive here. We will learn about the last remaining natural population of Puerto Rican crested toads, found here in vernal pools. More than half, 9 of 16, of the endemic bird species also occur here, including the Puerto Rican vireo and the Puerto Rican nightjar. Endangered plant species include the sebucan cactus, the violeta tree, and the critically endangered bariaco.

    After our hike, lunch will be fast food on the road as we head out for our longest drive of the week to Centro Educativo Amigos de las Tortugas Marinas, about two hours away. This facility has been dedicated to protecting sea turtles since 2001. We will meet the leatherback turtles and, hopefully, new hatchlings in their care, learn tagging methods, and walk the beach to see nesting sites.

    We’ll say goodbye to the turtles and head to our hotel for the night, it’s just down the street. You are welcome to relax this evening or hang out with the group. There are several restaurants within walking distance.

    Day 6: Wednesday, Nov 11

    7:45 am – Grab your gear and hop in the van: it’s time to shift our focus to tropical forests. We’ll drive for a bit over an hour to the Sabana Field Research Station in El Yunque National Forest. This research station, managed by the US Forest Service, is part of the International Institute of Tropical Forestry. We will learn about the different research projects being conducted in the area, including the Luquillo Experimental Forest. At 28,516 acres, it is the largest tropical forest within the experimental forest and the only experimental forest with the same boundary as a national forest (El Yunque National Forest).

    The Sabana team will share presentations and take us to visit one of their experimental sites as well as give us a tour of the station setup, complete with a demonstration of their field equipment.

    After our tour, we will head to the seaside village of Luquillo for two nights’ accommodation next to the beach. Your afternoon is free. But you may want to take a nap for tonight’s adventure.

    After dinner, we’ll head out to boat the bioluminescent waters of Laguna Grande on an all-electric boat out of Fajardo. We’ll learn what makes the water glow in a one-hour excursion. Please note that the intensity of the bioluminescence directly corresponds to the intensity of moonlight. For this evening, the moon phase will be waning gibbous, not a full-moon bright, but not a waning crescent moon. While the water may not glow as brightly as wished, we’ll enjoy an evening boat ride and learn about the phenomenon.

    Day 7: Thursday, Nov 12

    5:30 am – Early bird gets the worm, rather, it gets the bird! We’ll meet early for an all-day birding tour of two sites with staff from the nonprofit organization Para la Naturaleza. As a part of the Puerto Rico Conservation Trust, this group manages more than 40,000 acres of protected natural areas and historical spaces on the island. Our first stop is Medio Mundo y Daguao, the most extensive Natural Protected Area under their management and the second largest mangrove forest in all of Puerto Rico. The area’s varied ecosystems provide habitats for some 26 species of rare, endemic, vulnerable, and endangered species, including the West Indian Manatee, yellow-shouldered blackbird, Puerto Rican boa, and several species of sea turtles.

    After our hike, we’ll eat lunch at a local restaurant, then make our way to our second stop, Estación Palo Colorado in El Yunque National Forest. Here we will bird along the trails and some sections of the road.

    Endemic birds that we can potentially see are the Puerto Rican oriole, Puerto Rican woodpecker, Puerto Rican flycatcher, Adelaide’s warbler, Puerto Rican tody, Puerto Rican emerald hummingbird, green mango hummingbird, Puerto Rican tanager, Puerto Rican spindalis, Puerto Rican bullfinch, and yellow-shouldered blackbird. Other birds of interest are the scarlet ibis, American flamingo, Caribbean elania, green-throated carib hummingbird, Antillean or Hispaniolan mango hummingbird, and other migratory birds.

    After ending our bird tour, we will head back to our hotel. You are free to enjoy the evening on your own or with the group.

    Our birding tour guides: José Pedrogo has a Bachelor’s degree in Audiovisual Communications and is working toward a Master’s degree in History. He started exploring the island by himself and then pursued a certification as a tour guide. After working in the industry, José decided he needed to offer something more than recreation to the public. He learned about environmental interpretation through his tourism professor and completed the training, leading to his position as an environmental interpreter. He enjoys learning and fulfilling his dream of teaching. Our second guide is José Torres. He graduated from Agricultural Sciences with an emphasis on Entomology. He has been associated with Para la Naturaleza for many years, starting as a volunteer with the Summer Immersion Workshop and then as a mentor. He’s always been involved with nature and has an extensive background, knowledge, and experience.  José has been a pioneer in the work that has been done by the organization in El Yunque, such as the creation of tours.

    Day 8: Friday, Nov 13

    7:30 am – We will meet with luggage and gear ready for another hike in the tropical rain forest of El Yunque. Our trip leader will take us through the rainforest, on the lookout for potential birds, plants, flowers, orchids, amphibians, and fungi on this short hike, ending at the Rio Mameyes. If you choose, wear your swimsuit under your hiking clothes, and bring water shoes and a towel for a cooling dip in the river. After our swim, we’ll walk back up to the El Portal Visitor Center to purchase lunch.

    We’ll spend our early afternoon at the visitor center, learning about the endangered Puerto Rican Amazon parrot with the project leader of the Puerto Rican Parrot Recovery Program, Marisel Lopez. Marisel will explain the program and introduce us to three rehabilitated parrots living there that are unable to live in the wild. Unfortunately, we are unable to tour the aviary this time of year due to the parrot’s breeding season. The aviary is a part of the US Fish and Wildlife Service.

    Our El Yunque hike leader, Mónica Rosario, or Momo, was born, raised, and still lives on the island of Puerto Rico. Originally from San Juan, she now resides in Guaynabo. Momo has a double Bachelor’s in Visual Arts and Education and is currently a full-time art teacher at a private school. Her love of nature is a hobby that gives her an overall sense of peace. She enjoys exploring a place to find the little hidden gems, like fungi, flowers, small critters, and birds; those are all things she loves to see on walks. She draws and paints botanical illustrations, which is why she concentrates on observing flora. She collects specimens when the opportunity arises, too.

    Our Amazon parrot leader, Marisel Lopez, manages the El Yunque National Forest aviary and oversees critical efforts to rebuild the wild population, including managing captive breeding, monitoring releases, and ensuring the survival of this endangered species

    From here, we will head back to San Juan for the final night of our journey together. The afternoon is free. Later, we will meet up for a farewell dinner in the evening.

    Day 9: Saturday, Nov 14

    We will meet after breakfast, then head off for a morning tour of Castillo San Felipe del Morro. The afternoon is free for you to explore.

    OUR NHSM LEADERS:

    Jayne Ash, NHSM’s Field Trip Coordinator, designed this trip to reflect the diversity in landscapes, flora, and fauna that is often overlooked when traveling to Puerto Rico. Her love of all things nature inspired her to fill an itinerary with learning opportunities from experienced leaders on a diversity of topics. Her travel style has been honed over the last 15 years, during which she has extensively traveled to more than 40 countries, often for a month or more at a time. This will be our first trip off the continent for NHSM. She welcomes all those with a spirit of adventure to join her on this new avenue for NHSM.

    Our second NHSM leader is Dave Webb, an editor with Maryland Biodiversity Project, a nonprofit organization dedicated to cataloging the flora and fauna of Maryland. An avid birder for many years, Dave has broadened his interests to anthropods, especially those found in soil. Dave also edits BugGuide.net, vetting the identifications of arthropods photographed by other outdoor enthusiasts, including his own photos.

    WHAT’S INCLUDED:

    • All accommodations in two- to three-star hotels. Double rooms will be shared by two people, with two beds available. For two nights in Luquillo, a couple of us will share a common room with single and bunk-style beds, which may include mixed genders. No upper bunks will need to be used unless a top bed is preferred. Single supplements are not available. Hotel costs are very high, and this is an attempt to keep your price point lower.
    • All activity fees, including guiding fees. Tips will be paid through our tip kitty. See details in the “What you Need to Know” section below.
    • All entrance and admission fees to sites visited.
    • All transportation during the trip is in an 11-passenger van driven by a private driver.
    • Meals included: four breakfasts only. All other meals are at the participant’s expense.

    WHAT’S NOT INCLUDED:

    • Airfare
    • Airport transfer to and from the hotel
    • Food, snacks, water, and drinks
    • Any items of a personal nature

    WHAT YOU NEED TO KNOW: 

    • NHSM requires everyone to have valid travel insurance covering personal injury, medical expenses, and emergency repatriation (minimum $200,000) for the entire duration of the trip. Proof of insurance, including the policy number and 24-hour emergency contact, must be printed and given to the group leader at the Welcome Meeting, or you cannot join.
    • Every participant will be required to sign a Terms and Conditions Agreement before arrival. It will be provided in advance for you to read.
    • A tipping kitty will be created at our Welcome Meeting on Day 1. Every participant will need to add $100 in cash to be used for tipping hotel and restaurant staff and trip leaders, including our driver. A running tally will be kept of expenses, and any leftover funds will be divided equally between participants on the final day of the tour.

    IS THIS TRIP RIGHT FOR YOU?   Moderate Activity Level

    • This itinerary contains many early-morning starts and full-day activities that include moderate hiking, up to three hours a day of van transportation, and snorkeling in tidal waters. Please note that participants may choose not to participate in an activity; however, no refund or alternative activity will be available. Passing on an activity may result in you waiting in the van for the group’s return. The pace for all activities, especially hiking, will be set by the slowest member of the group. You must always remain with the group while in the field. No one will be allowed in front of the leader.
    • As with any travel experience, participants must be open to changes to this itinerary, food options and costs, and other minor inconveniences as may become necessary due to weather, time constraints, or unforeseen circumstances. Being flexible and adaptable to new and changing situations remains a key component to successful travel, even with the best planned vacation.
