Ecoregions of North America, featuring the 50 United States, the District of Columbia and the 5 inhabited territories The following is a list of ecoregions in the United States as identified by the World Wide Fund for Nature (WWF). The United States is a megadiverse country with a high level of endemism across a wide variety of ecosystems. Terrestrial ecoregions[edit] The United States is unique among countries in that its terrestrial ecoregions span three biogeographic realms: the Nearctic, Neotropical, and Oceanian realms. 50 states[edit] Alaska is the most biodiverse state with 15 ecoregions across 3 biomes in the same realm. California comes in a close second with 13 ecoregions across 4 biomes in the same realm. By contrast, Rhode Island is the least biodiverse with just one ecoregion - the Northeastern coastal forests - encompassing the entire state.[1] The terrestrial ecoregions of the 50 states of the United States are as follows: Realm Biome Ecoregion State Nearctic Boreal forests/taiga Alaska Peninsula montane taiga Alaska Nearctic Boreal forests/taiga Cook Inlet taiga Alaska Nearctic Boreal
