Compatibilities with other mods ? Yes it has! I tested and works with Space Exploration but the process is somehow slower compared with a vanilla game. The tests were made with 1 tick span rate and game at 10 time speed.

the script effectively checks the count of type tree entities at a random position in a random chunk on each surface.
it requires at least 2 trees in good shape (not too much polluted) in the given radius to spawn a new tree.
this means if you have a surface with lots of space without trees and/or pollution the chance to hit at least a pair of trees is quite small.

We created this mod having space exploration installed and active, so the preset tick rates in our mod must roughly match the intended in-game behavior. I haven't really test this with vanilla so if the regeneration rates differ we probably need to dig into this.
