This document provides an introduction to identifying tree species. It discusses why identifying trees is important for land management, enjoyment and education. The document then describes some basic tree anatomy and different methods for identifying trees, such as leaves, bark, and fruit. It introduces the concept of a dichotomous key and provides a basic leaf key to demonstrate how to identify tree species step-by-step based on leaf characteristics. The key asks questions about whether leaves are broad or needle-like, opposite or alternate, simple or compound, and more, to systematically narrow down possibilities.
