The other day, while playing Factorio (0.15.38) I damaged a tree with a grenade. It was almost destroyed, had red health boxes. I went to chop down several other trees and when I got to this one, the health boxes were yellow.

Do trees regenerate after taking combat damage, like the player does?

Do biters, and/or biter nests?

From personal experience, things do heal after being damaged some (trees, biters, biter nests, etc). The only things that don't are structures. Those you have to repair.

    In fact, if you hover you mouse over the tree, you can watch it's health go back up.
