Been using this since updated for 17. Just updated and got this:

Failed to load mods:tree-growth-scaled-trees/util/tree.lua:39:attempt to perform arithmetic on field 'emissions_per_second'(a nil value)
Stack traceback:

P.S. I really enjoy this mod. Thank You!

Edit: Seems to be a conflict with Alien Biomes Mod...Error is gone without Alien Biomes.

Hmm. There is an obvious bug in this mod, in that it assumes that all trees consume pollution (or at least, have that defined).
I will address this crash, but it might be that the trees modded by Alien Biomes don't absorb pollution at all, in which case the scaled versions won't either.

Fixed in 2.3.3

Thank you!
