You are able to do this. There should be some info in either the Fantasy Fridays or some threads (sorry I don't remember off hand). There is dynamic fire in the game, where grass, trees, buildings, wheat, units/animals, etc, start on fire or take damage. Things like wheat and trees will loose their resources when burnt.
The fire when spread through forest or the grass will leave the terrain black. So this is some terrain destruction.
