This isn't a biome mod, no new tree generation has been implemented. 99% of the content is a resource pack; the only "mod" mechanic is the reimplementation of pink wood. See below.

!8 different colored wood planks

In order w/changes:

• Bamboo, removed the green hue to match real bamboo plank tones.
• Mangrove, now orange to match real life mangrove. (Yes, mangrove is orange. Only the skin is red).
• Bulnesia, replaces acacia. Mangrove is now orange, changed to avoid repeats.
• Purpleheart, replaces cherry in the overworld. See rosewater.
• Crimson, actually red.
• Rosewater, used to be cherry. Obtained by cooling (right-clicking) crimson in water.
• Malachite, replaces warped only in name.
• Azurite, completely new wood set. Obtained by cooling (right-clicking) malachite in water.

While still 100% usable, this mod is not thought to be backwards compatible with already created worlds. Purpleheart and bulnesia WILL replace your cherry and acacia builds. If this is something you're okay with, you are free to use it on your older worlds, it will otherwise not break anything.
