This mod does not work as advertised. It removes all trees and rocks, yes. However, take extreme care as to when you apply it, meaning, it may work as intended on a new map. I used it on an established map and it cleared all my rocks and trees despite me checking the settings for rocks only.
I have since removed the mod and as of yet, still no trees to be found (possibly due to my terrain settings, but doubtful). Rocks have returned and are being spawned.
