When identifying a tree, one must take careful note of at least SIX characteristics of the tree. Every tree has its own branch structure. Willow tree branches sweep in long arcs from the first branching. The White Birch's branches are nearly horizontal. One sure way to concentrate on this aspect of a tree is to take the time to sketch the branch structure.
Tree bark varies in color and texture.
The leaves will be out soon as spring is just around the corner. There are three main ways that leaves are placed on a twig. They can be placed directly across from each other. And they can be placed in sets of three or more at one level. Placement of leaves is also the determining factor in the classification known as simple or compound.
