Drops from trees

Drops from trees are items that you get when chopping trees.

How are drops determined
Drops are defined by Foliage (leafy part of the tree) and Stem (woody trunk of the tree). Each Sapling is a combination of 1 Stem and 1 Foliage.

For example,  foliage gives 1 Protocite and 1 Sapling, and   stem gives 3 Wooden Logs. By cutting a "protoleaves + prototree" tree, you get both.

Furthermore, you don't just get 3 Wooden Logs, this number is multiplied by height of the tree.
