Dichotomous Tree Identification Key

What is a dichotomous key? A dichotomous key is one tool that can be used to identify trees. This type of key is also used for flowers, animals, rocks, fish, and more!
A dichotomous key contains a series of choices that lead the user to the correct name of an item. "Dichotomous" means "divided into two parts." Therefore, a dichotomous key will always give you two choices in each step.
