Identifying Common Trees and Shrubs in the Eastern U.S.

In this episode of All Things Wetland Plants, Jennifer Goulet, of the U.S. Army Corps of Engineers, describes field features for identifying nearly 50 commonly occurring woody plant species (trees, shrubs, and a few vines) in the Eastern U.S. Species are organized into groups based on leaf characteristics. See below for list of species reviewed and timestamps for each group.
