In map editor there's an tool that allows you to place multiple pros with he use of brush. This tool is restricted to "Enviroment" section which allows you to place trees, bushes and rocks without placing them manually one by one.
Trees height changes the scale of the prop, is it's set at 1x then trees (or rocks) will have a size (scale) from 0,8 to 1,2
I reccomend using 4th brush but remember that this tool isn't ideal and when some tree props are collinding you must move them manually.
Because rocks are blocking the vision, they are skipped in this guide.

Anything that blocks AI vision impacts framerate performance. If your area isn't really utilized during the battle, then scrap some trees.
1000 palms will not hit perfomance as much as 1000 Pine trees
