Comment 12 for bug 1348800

I looked at this some time ago, there is some systematic (mathematical) problem with poor terrains. Picking of tree type is one thing and speed of growth is second. Algorithm implies that yield of best terrain:poorest terrain is 95:5. Too big difference. More over if I tweaked the parameters to help poor soil, trees grew like crazy on good soil - not balanced.

So what I mean sole parameters change would not do - but I might be wrong of course...
