I just generated a new map, I have a pretty large selection of mods including most of Bob's and Alien Biomes, and all 4 of your tree mods. I see zero tree expansion and trees are not being marked for removal due to proximity to buildings. All my other mods are functioning great but I cannot tell that any of yours are working at all. I have used your mods in the past with great success so I don't know what changed.
Update: I loaded a new save with nothing but your tree mods and left it open for 20 minutes with zero growth. I also noticed no tree size variance as well as no trees being marked for removal next to a few things I placed.
