Please sign up for the waitlist if this class is full. 

The two-day class will emphasize field character identification of the most common freshwater, estuarine wetland, and associated upland buffer species found in the Puget lowland region of Washington State. The format will be a lecture/laboratory setup. Ample dried material will be available for everyone to practice their keying skills.

Each class will begin with a short lecture covering the terminology and salient morphological characteristics needed for a taxonomic identification of the species of choice, field characteristics, some ecological aspects of the species’ common habitat, commonly associated species, distribution, potential use for restoration purposes, and any special ecological requirements. Lecture materials will include drawings, slides, and dried plant material. The class instruction will be oriented towards the needs of shoreline planners, delineators, OHWM determinations, and restoration ecologists.
