# Biome Tags

This content applies only to Java Edition.

Biome tags are groups of biomes.

## Usage

Biome tags control structure generation, mob spawning, and many other functions. Commands such as `/locate biome` and `/execute if biome` can also reference biome tags.

### `#has_structure/abandoned_camp_*` (18 tags)
