Welcome to Arctic Expansion, a plugin which aims to add a bunch of new arctic (or just generally cold) terrain features, like trees and biomes.
...I'm releasing a "beta" version of this, since I've kind of stopped developing this, but I still wish to let others to use this plugin. I've built a bit of hype for this, so it's only fair I release even an incomplete version...
Do note that this version is incomplete. Biome generation, even if implemented, is not properly configured. Use biomes with caution.
