Northern America

Northern America is the lower section of one of the world’s eight major biogeographical realms – the Nearctic – which spans from southern Canada to northern Mexico. This realm division includes 22 distinct bioregions, with a large range of diverse biome types. There are six major groupings of bioregions – the broadleaf forests of the Northeast, the savannas and mixed forests of the Southeast, the great grassland prairies of the Midwest, the deserts and mountain forests of the Southwest, the conifer forests of the northern Rockies and Pacific Northwest, and the Mediterranean region of California. The forested island of Bermuda is included in this realm, but the southernmost tip of Florida is not included as it marks the transition to the Neotropical realm.
