I was thinking along these lines, but I fear too many trees is a bad thing for the game to handle.
I was thinking of some sort of tree canopy tool, or "scenery pieces" that would essentially be a tree roof, of different shapes and sizes, that one could use to fill the inner section of a forest, without having to plunk down 100 trees. If that makes sense?
So, like, you could make an outline of your forest with trees, as if they were walls, and then put tree top roof pieces in the center. It would save a lot of polygons.
