Tree Classification Essay

I have to do a Tree Classification project. Next time I'll add some pictures of my projects. It turned out to be a really neat project. We over over 15 types of trees on our property.

I found fifteen different types of leaves to research and do a tree/leaf classification on. I choose four different traits to use to classify each leaf and then out of those four I was able to break them down even further into other categories.

The four traits I picked were; Tree type, shape, texture and arrangement. I felt like some of the traits were very easy to identify, like shape, but others like texture were harder to determine. It was very interesting looking at all the different varieties of leafs, especially when they belonged to the same tree family, like the maple for instance.

I choose four different maple trees. The first was a Japanese maple, then a silver maple, red maple and finally a crimson maple. The interesting thing about that is that some had very similar traits, but others were totally different and had nothing in common, yet they all were maple trees.

I enjoyed this project and hope others especially tree observers will find it as interesting as I did.
Traits (used to classify trees) I think all the traits were easily identified, but shape was the easiest and texture was the most difficult. I feel my classification system is very useful because it is simple and easy for the beginner tree observer to understand. The limits to this tree classification system are that it is solely based on one individual’s perception of the tree and the tree leaf and is only classified by those traits.
