Growing Trees above ground in Dwarf Fortress

dwarf-fortress

This is in reference to Dwarf Fortress 40d (v0.28.181.40d). Later versions of this game have significantly changed the related mechanics.

I just embarked on a map with 6 trees on it. There is a small (about 100 tiles total) bit of greenery, and the rest is a mix of red sand and felsite.
If I pump water up and turn the ground muddy, will the forest spread? Would the muddy section have to be next to the existing green area?

Best Answer

To answer the question about muddying the area, no. If you muddy an area it will not cause the forest to spread as the areas where the forest grows is determined by the biomes (which are visible when you choose your location to embark to) no soil type.

Though, trees do sprout randomly, so go ahead and cut down the ones that are on your map for now. There really is nothing you can do to increase your fortress's wood production. unless you find an underground river or pool. if you find either of those, muddying an area underground will cause it to grow tower cap mushrooms which can be used as wood.
