An old growth birch forest or birch forest mutated is a variant of the birch forest, notable for its trees, which are taller than those found in the normal birch forest.

Generation

Old growth birch forests replace birch forests in positive weirdness and consequently often border rivers as well as their regular biome variant.

Like birch forests, they generate in medium temperature between forests and dark forests in terms of humidity. They can also border taigas and jungles, as well as oceans or temperate mountains. Because of their high humidity, old growth birch forests commonly have lush caves beneath, but not when generated more inland.

Description

The old growth birch forest features birch trees, half of which are significantly taller than normal with trunks up to 14 blocks tall. These tall birch trees are exclusive to the old growth birch forest and cannot be grown with a normal birch sapling. Bee nests can be found on 0.2%‌[JE only] or 0.035%‌[BE only] of the trees. Fallen trees can also be up to 14 blocks long.

Flower patches that naturally generate in the biome include the rose bush, lilac, peony, lily of the valley, and wildflowers cover the ground. Small patches of up to five bushes are also present.

Additionally, trail ruins may generate here as opposed to regular birch forests. Abandoned camps sometimes generate in old growth birch forests.​[upcoming: Third Drop 2026]
