Impassable forest and woodland are placed according to map_gound_types.txt, the type of tree that gets used is effected by the combination of that and map_climates.txt (ie different ones are used in different climates) see the colours listed in the tutorial at the start of this for which colours are which.

Are you trying to place something very specific / or in specific location?
Guess the question wasn't very pointed. :)

Let's say you wanted to create a denser\impassable forest for a stretch along
the steppes just above the Crimea...in our case, to prevent the Bosporans from going north so easily, and in effect funnel them south. It's those files that determine it? And is it just 'hit and miss'? Make a change and then look and see if you got it in the right place. LOL :)
