A bioregion is a geographical area, on land or at sea, defined not by administrative boundaries but by distinct characteristics such as plant and animal species, ecological systems, soils and landforms, human settlements and cultures those attributes give rise to, and topographic features such as watersheds. [1][2][3][4][5][6][7][8] The idea of ...
The term bioregion as it relates to bioregionalism is credited to Allen Van Newkirk, a Canadian poet and biogeographer. [28] [29] [30] In this field, the idea of "bioregion" probably goes back much earlier than published material suggests, being floated in early published small press zines by Newkirk, and in conversational dialogue.

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).

A map of the bioregions of Canada and the US. An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of ...
The Cascadia bioregion is the Pacific Northwest as defined through the watersheds of the Columbia, Fraser and Snake Rivers, as defined through the geology of the region. [1] It extends for more than 2,500 miles (4,000 km) from the Copper River in Southern Alaska, to Cape Mendocino, approximately 200 miles north of San Francisco, and east as far ...

The United States is part of North America. The environment of the United States comprises diverse biotas, climates, and geologies. This diversity leads to a number of different distinct regions and geographies in which human communities live. This includes a rich variety of species of animals, fungi, plants and other organisms.
Antarctic (not shown) A biogeographic realm is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions. A biogeographic realm is also known as "ecozone", although that term may also refer to ecoregions.
