Trees and magma
« on: January 15, 2018, 03:06:58 pm »

How do trees react to getting a magma bath? Will this create endless FPS killing collapses, and leave a bugged surface as an added bonus, or is it a viable way to get rid of excessive tree spawn?

I've had cavern trees that were standing in magma (due to a naturally overflowing magma pipe), and the branches caught fire from time to time to ignite the cavern moss, but he trees didn't die and branches regrew to be set on fire again. Thus, I suspect it won't do much. At best/worst I'd expect the same results as a fire.

Embark in deserts with a rainfall of less than 4 (if I remember correctly) and no new trees will spawn, with rainfall less than 2 (I think) also stopping shrubs from spawning. You can still farm there.

Nah, still too fond of this fort despite the seasonal lags caused by diplomats. Slowly paving the surface to reduce tree growing space. Or eventually, I'll restrict trees to the other side of the walled off river, so I can magma flood the paved surface on my fort's side.

The leaves burn away but the trunk stays as a burnt trunk, so nothing collapses. I'm not sure on the effect magma has on saplings but I'd guess they'd burn.

Normal fire causes a bajillion "Something on the surface has collapsed!" notifications when used in a wooded area. The trunks still endure, albeit horribly burned, but they have a bad tendancy of falling over and horribly crippling your woodcutters if you try to end their misery. The surface collapsing also punches holes in rooms just underneath a flaming tree, which is weird and potentially dangerous. I don't know if magma would get different results, but I suspect not.

In 43.05, magma did not start fires or cause damage unless it entered the tile, so a tree trunk, a constructed wood wall, and a closed wood door, would all block magma without bursting into flames. A sapling does not block magma from flowing into the tile so I suspect it burns. Not sure about paved roads.

Paved wooden roads can burn (my only experience was caused by fire from the only dragon I've seen, though). I would expect magma to set fire to roads made out of materials that can burn, though.

Wait, can you fry elven caravans this way?

Probably. Sounds like far too much work to be worth it, though.

Makes me remember that forumite that made a freeze trap for elven caravans. Freezing biome, run magma underneath depot, flood depot, turn off magma, enjoy your elf icecream.
