EPP721 - Winter Twig Identification

Course Description

This class will emphasize field character identification of the wetland species and associated upland buffer species found in the Puget lowland region of Washington (approximately 12 trees and 60 shrubs, including willows). The format will be a lecture/laboratory setup. The taxa examined will include common lowland, freshwater (and a few estuarine) species. Fresh material will be provided if in season. Winter characteristics (buds, leaf scars, pith, and bark) will be covered.  The class instruction will be oriented towards the needs of shoreline planners, delineators, OHWM determinations, and restoration.

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 plant material
