Winter strips trees down to their essentials — bark, buds, branching structure, and form. While leaf-on identification gets the spotlight, winter is often the best time to truly learn your trees. Without leaves, you’re forced to slow down, observe carefully, and understand how species differ at their core.
For landowners, restoration practitioners, and anyone managing Midwestern landscapes, winter tree ID is especially valuable for spotting invasive species, planning management work, and learning the native trees that shape our forests and savannas.
Below are some of our favorite Midwest-relevant tree identification books and resources to keep learning all winter long.

- Builds stronger ID skills by focusing on buds, bark, and structure
- Perfect for winter walks and site assessments
