Biome

A biome is a region in a world with distinct geographical features, plants, mobs, temperatures, humidity levels, colors, and more. Biomes separate every generated world into different environments, such as forests, deserts, and oceans.

The biome of a location is determined during world generation rather than by the current environment, even if all blocks in a large area are altered to imitate the terrain of other biomes.

Existing biomes can be located with the /locate biome command. The /fillbiome command in Java Edition, or the "Biome Data Assignment" tool in Bedrock Editor can be used to change the biome in a selected area.
