Tree growth

Underground trees spawn in newly created suitable locations once their biome is uncovered. So far, this requires a Subterranean tile of soil, with a full soil wall underneath it. They do not spawn on subterranean soil tiles located above rock walls. From Toady's comments, I speculate that they will spawn on subterranean muddied tiles without a full soil wall beneath them. I have not tested this second hypothesis.The Architect 05:53, 26 April 2010 (UTC)

That would be entirely consistent with behavior from 0.28.181.40d. --Quietust 12:52, 26 April 2010 (UTC)

I have the surface level (z 0), then below that I have a whole z level of soil mined out (z -1). Below that I have a whole z level of soil mined out (z -2). Below that I have rock all mined out (z -3). Plants grow on z -1, but not on z -2. I think that confirms what you were saying. Mason ^(T-C) 16:38, 26 April 2010 (UTC)

They will spwan quite happily on muddied areas of soil. This has happened on several maps I've played where I've flooded some farmland and access corridors, then found underground trees. They then grow on the muddied areas not covered by farm plots.--Nimblewright 16:59, 1 May 2010 (UTC)

As of 0.31.25 the comments here might no longer be correct. See also http://www.bay12forums.com/smf/index.php?topic=93501.msg2630579#msg2630579. It seems that trees always grow on soil. No matter what tile is under it. --SGdYy409Ls 12:04, 23 September 2011 (UTC)

Any list yet of the colours of the wood, and the products thereof? I know that at the very least, feather wood and the underground wood have different colours. --AndrDrew 00:13, 6 May 2010

'Saplings will not grow on a tile with items on it' Is this correct? In 40d saplings grew fine in occupied spaces but didn't mature into trees until the tile was cleared. --MLegion 15:58, 17 August 2010 (UTC)

Erosion caused by cutting trees?

So i embarked on a area that had 2 types of sand and was heavily forested. After i chopped down the trees near my wagon, the grass tiles started to turn into sand ones, while the areas with small forest kept the grass.

Erosion took a month or so.

are you sure it's erosion, or is it just dwarves tracking over it often and trampling it, like how they do with saplings/bushes?--75.6.250.65 22:54, 28 November 2010 (UTC)

Glumprongs Missing from New Version

I cannot find Glumprongs anywhere and I only embark in evil areas. Please post if you have evidence that they exist in the new version.--74.77.203.51 10:48, 5 May 2011 (UTC)

See ^Bug:4133, this suggests the addition of grass in 0.31.19 has caused GOOD and EVIL plants to show up rarely or never. Hv 16:35, 22 October 2011 (UTC)
