Bioregions became a foundational concept within the philosophical system called Bioregionalism.A key difference between an ecoregions and biogeography and the term bioregion, is that while ecoregions are based on general biophysical and ecosystem data, human settlement and cultural patterns play a key role for how a bioregion is defined.
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.

This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
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 map of the Amazon rainforest ecoregions. The yellow line encloses the ecoregions per the World Wide Fund for Nature. 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.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude , elevation , isolation and habitat area . [ 1 ]
The Canadian Shield bioregion extends across the northern portion of the continent, from the Aleutian Islands to Newfoundland. It includes the Nearctic's arctic tundra and boreal forest ecoregions. In terms of floristic provinces, it is represented by part of the Canadian Province of the Circumboreal Region.
