Dichotomous Key:

Identify an Unknown Tree You Found on Campus

This Dichotomous Key can help identify trees covered in other sections of this guide by asking a series of questions. If results here do not match up with your tree well, you can revisit questions that you previously completed to go down a different path. Alternatively, your tree might not be covered in the Pacific University Tree Guide.
