Dichotomous Tree Identification Key


A dichotomous key is a tool that can be used to identify trees. 
 
"Dichotomous" means "divided into two parts." Therefore, a dichotomous key will always give you two choices in each step and following all the steps will lead you to the name of the tree you're identifying.
 
How to use this key
 
1) Use the leaves from a tree or find a picture of a tree you want to identify and click on the most appropriate match to the right.
 
OR
 
2) Click one of the numbers below to identify one of our mystery trees. If you end up with two matching pictures you have identified the tree correctly.
