Bioregions

A bioregion is a living place defined by its watersheds, soils, climate, species and cultures rather than by borders. Here are the 185 bioregions of the Earth, with the places, people, organisations and activities we know of in each.

Based on the One Earth Bioregions 2023 framework. Names and codes are One Earth’s; the descriptions are our own, and boundaries here are approximate, so matches near the edges may be off.
