Grasses and grass-like plants form a key component of most plant communities yet are notoriously difficult to identify. This is due to many factors, the most prominent of which are that grasses, sedges, and rushes (i.e., “the graminoids”) are usually small, narrow-leaved plants with unassuming, diminutive flowers – and they all look alike!

This course is designed for individuals interested in learning how to tell the difference between these three easily confused groups of plants. It is intended to improve Grass, Sedge and Rush (GSR) identification skills in wetland and adjacent upland habitats with emphasis on key field characteristics of select genera of GSRs. The course will include a combination of in-class lectures, instructor-led keying, and field identification at local habitats.
