Trees above the tree line

Just something that bothers me:

There shouldn’t be any trees around Point Barrow, AK. I know the game autogenerates trees, but there shouldn’t be any trees in the Arctic circle.

I agree, it should be a minor adjustment to restrict AI tree generation to below the arctic latitudes, and at specific altitudes, depending on the earth latitude (e.g. Andes 0’-10’, ~11,000 ft, Himalaya 29’-32’, 15,000 ft., Alps 42’ - 46’, 9000 ft., Lapland 68’ 2000 ft.)
