Forest regrowing formula?

[VetLegion]

What is it? Or at least, does the probability of a tile regrowing a forest depend on number of forests in the vicinity of that tile?

I've done experiements but not been able to work much out alas. Pressing enter a million times is OK when it's about barbarians, but forests just don't hold enough facination on their own.

I do wish they sometimes sprouted from 'nowhere' though.

I've noticed that forests with lumbermills don't seem to spread at all, whereas forests with large un-built spaces around them spread, but only very small amounts and usually only during the beginning of the game. I think putting a road through a forest also cancels its ability to spread.

I think forest growth is tied to 'years' not turns. So by the time you get lumbermills you only have a couple of hundred years to go and have had several thousand so almost all of the forest spread will have happened, plus, many of the possible spread squares will be otherwise engaged.

that makes sense WRT RL; also, consider that a lumbermill-intensive civ (in RL) would /manage/ the forests, preventing spread & encouraging better workable timber - think coppicing & UK Forestry Commission policy as-was
