I'm on my second fortress, and I've encountered a problem I didn't really expect: I'm chronically short of wood. I embarked into a forested area, so I had plenty to begin with, but now I don't have enough to do all the crazy stuff I want to. There are plenty of saplings on the surface, so I haven't totally killed my supply, but still.
So, how might this have happened, and what can I do about it? When I started this fort, I was thrilled to find that the first few z-levels are rife with iron and copper ores (a lack of iron was why I stopped playing my first fort), so I've been making a lot of steel. Maybe I should cut that out for a while? Is there any way I can plant trees?
Alternatively, how can I reduce my dependence on foreign… er, surface wood? I'm considering the following:
- Digging down for magma
- Digging down for lignite or coal. I'm in a sedimentary layer, so that might be easiest?
- Digging down for tower-caps. Aren't these associated with caverns/fun?
Actually, I guess those are all sort of the same plan. Any other ideas for conservation or alternative energy sources would be great. (What ingredients do I need for solar panels? :D)
