What Tree Is It, an online guide to trees commonly found in Ohio, allows users to identify trees using a tool, which follows a dichotomous-key format. You may see an unknown tree. Or perhaps you find part of a tree, and you want to know from what kind of tree it came. Often, you can identify an unknown tree by just one part, such as a leaf or a fruit. This resource leads you through qualities of leaves and fruits from the common trees of Ohio. You may work your way through these choices by selecting images that more closely resemble your sample. To be certain of your identification of an unknown tree, however, you must use as much of the tree as possible. This Ohio tree identification program was created by the Ohio Public Library Information Network (OPLIN) and the Ohio Historical Society (OHS). (author/kt)
