How to identify a tree by its bark?
Identifying a tree by its bark requires practice. Bark characteristics can change drastically as the tree ages. Bark differs from species to species by color, texture, and pattern. The bark for some species may be more distinct than others, so start with taking serious note of the bark on the trees that are in your immediate surroundings. Use the leaves to confirm the species. Then try to spot this tree species by bark in other places close by. Once you’ve mastered one species of tree, move on to the next, paying special attention to differences with the first.
