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 get way more than just 3 Wooden Logs, because this number is further increased by the height of the tree.

Making custom trees
If you have two saplings: one with foliage A, another with stem B, then you can use the Cloning Lab to create an A+B sapling.
