Hey CobaltSky,
Like your mod.
I'd like to add the following, you are kinda doing it, just tweaks.
Trees Dying. Have trees die, but more so in deserts/sand/red soil vs. the green. Kinda like you have the fertility, but the opposite.
Have dead trees be removed. Not as fast as they would die, but eventually they should be removed.
Trees should die faster in polluted areas. (Think you're doing this)
So in a long game, there would be forests in green areas, and deserts would be barren....
Cool mod!
