The method reflects proportions in the number of leaves of different sizes and shapes, which appear in a tree stand.

Differences among all three samples were significant, which indicates different size of falling leaves in the following periods. Thus, only the research carried on at the end of leaves falling allows collecting a sample which represents proportions among leaves of different sizes in the tree stand.
