Biomes are properties for spawn points that determine what types of Pokemon that spawn point creates. Biome type for a spawn point is determined by the point’s location and terrain. Unlike Nests, which migrate every few weeks, Biomes do not move. Biomes help determine frequent spawn locations for Non-Nest Pokemon. Biomes include: Desert Biome Water Biome Bug Biome Swamp Biome Electric Biome Oceanic Biome Grass Biome Mountain Biome Neutral Biome Please let us know if we missed any information.
