I don’t know if it’s been decided yet but I’ve been doing my reps on how to make /vnug/ still heavily forested even if it got changed into a tundra. Aspen trees are able to spread further north than many other trees as clonal colonies and thus bypass the temperature requirement for seed germination so maybe that’s how most trees in /vnug/ are (although I can’t find a lot of information on how trees evolve to be clonal)
Another tundra adaptation’s making the roots shallow and widespread but that also leads to the trees being shorter (like shrubs) and that doesn’t really fit with what I’ve envisioned so I don’t know if that’s the approach I’ll be using. One idea I have is that since we know dreamworts can break through soil pan and a bit of permafrost through chuubanite, maybe once dreamwort colonizes part of the tundra, it’ll be able to make the soil go deeper than usual tundra and thus allow trees to grow larger than otherwise? Trees might also be able to absorb residues from dreamwort to make their roots more resistant against winter frost
