Winter Twig Identification Professional Development Class

The class will introduce students to winter twig identification of wetland and riparian species common to central and eastern Washington. This is an important skill for those individuals who conduct wetland delineations as well as stream and wetland restoration, as delineations and site assessments often occur year-round.

The class begins with a presentation covering the terminology needed to identify tree and shrub species in the winter. Then, we will look at live plant materials to become familiar with the structures covered during the presentation. Next, we will head out in the field to identify about 20 different shrubs and trees. Finally, we will return to the classroom and use a winter twig key to identify additional samples.
