Well, these are the last six trees, you're almost done. The fourth oak species is most similar to southern red oak in appearance. On small trees look for a little fuzz on the buds which indicates a southern red oak, on larger trees northern red oak has long stretches of smooth bark that almost resemble ski tracks running down the trunk (Beware, there are many oaks we aren't covering). Blackgum is a very ambiguous tree, and one of the simplest clues is the little twigs that grow off most of the branches which curl to a single bud (some folks think of them like little pinky fingers all over the tree. Honeylocust is somewhat similar to black locust but has large thorns spread randomly around its branches, as opposed to small pairs of thorns at the base of each leaf. Finally, shagbark hickory has very different bark from mockernut hickory, but the end buds also have hard scales surrounding them which don't come off very easily. On mockernut they fall off easily. Enjoy!
