How can I identify trees by their leaves?

First, observe the shape of the leaves. Most tree species have distinct leaf shapes that can help you identify the tree. Additionally, pay close attention to the size and color of the leaves, as this can often be a tell-tale sign of what species the tree is. You can also take note of any unique features, such as leaf veins, which can be a helpful clue as to what type of tree you're looking at. Finally, see if you can find any identifying features, such as thorns, of the tree that can help you narrow down the possibilities of what type of tree it might be.
