The tall birch hills or birch forest hills mutated biome is a rare variant of the birch forest that no longer generates since Caves & Cliffs: Part II, and was removed in Java Edition.

Description

Old

Like the other hills biomes, the tall birch hills biome had hillier, rougher terrain, along with the taller birch trees of the tall birch forest variant. The hills were steep in this biome, comparable to the windswept hills biome.

Unlike most hills biomes, this biome used to generate as a "modified hills" biome, making it much rarer but also bigger in size.

Current

In Bedrock Edition, tall birch hills in older worlds still received updates. When generated through single biome or behavior packs, they can also generate new blocks.

They appear similarly to the old tall birch hills. Unlike regular old growth birch forests, wildflowers do not generate here, although bushes do. Trail ruins do not generate either, and no birch forest music tracks play.

Mobs

Tall birch hills use the same mob spawning chances as birch forests.

The following mobs spawn naturally here:
