It´s similar to the Forest Replanting Mod by rezaf. There you had to built an improvement and let your citizen work this title from city screen.
It´s compatible with Civ4 1.09
Version 1.0 changes:
* Made forest plantable with worker after tech paper.
in epic speed, one worker needs 30 turns to plant it
* reduced production gain of forest cut from 30 to 20
* increased forest and jungle cut time (+30%)
* increased forest and jungle regrowth rate (+30%)
* increased forest health to 0.5 (was 0.4)
* increased flooplains health to -0.25 (was -0.4)
* doubled defence multiplier of fortification
* increased whaling boats production to 2 (was 1)
Nobody really uses the fortification improvement, so maybe now it´s more
worth to use it. It should be more likely now that you use forest and
lumbermills, which is better than workshops. And don´t forget: workers also
cost 1 money per turn, so it will be difficult to exploit the forest replanting.
I wish i could change the AI behaivior of cutting every forest. I simply hate
that in all my conquerd land there is no more forest anywhere. But this mod
helps a bit for this problem.
It´s not much but I hope somebody has a use of this. If you don´t like the fact that you can
cut forest to gain production, simply don´t do it!
Have fun!
