Comment 49 for bug 654078

Here is a screenshot from an experiment. to give you some impression of the possibilities.
We are 28h into the game and the original map had an evenly mixed, dense patch of all 8 tree species, the size of a ranger's working area, placed in the middle of all terrain samples.
The tree paramenters are modified here already for all trees with the intention to prevent an overgrowth.
So no tree on this map is behaving the way you would expect from your experience.
Tree8 has been made are non-blocking and given a terrain affinity of 222 for all terrains.
Tree8 specimen set by the map maker and their siblings are filled white squares.
Tree8 speciment planted by the ranger are diagonally striped. They do not seed.

Please notice how tree8 is unrivalled on wiese1, while on bergwiese the larch is a superb competitor (terrain affinity of 232)
Also please mark how the tree8 placeholders do not block, and the general sparseness of the wood.
