Welcome to the Urban Tree Key, a resource for identifying common urban tree species with a focus (for now) on Northern California cities. The Urban Tree Key was developed as a component of the
Urban Forest Map project to provide people who are interested in participating, but perhaps not completely comfortable identifying trees, with the information they need. Of course, if you’ve come here by a different route, welcome! We’re glad you’ve stopped by. For this first version, you’ll find a step-by-step guide to identifying the 45 most common urban species in the region. Click the Start Here button above to begin.
