Biome tag (Java Edition)

A biome tag is a group of biomes. Biome tags are used to control where structures generate, the spawn conditions of various entities, and numerous other gameplay features. See below for the use of each tag. Biome tags can also be used when testing for biome arguments in commands with #<identifier>, which succeeds if the biome matches any of the biomes specified in the tag.

The biome tags are under data/<namespace>/tags/worldgen/biome folder of data pack.

These biomes must be present around a location where a monument is possible to generate.
