Ecoregions are identified by analyzing the patterns and composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity (Omernik 1987, 1995). These phenomena include geology, landforms, soils, vegetation, climate, land use, wildlife, and hydrology.
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.
Information and downloadable maps and datasets for ecoregions of North America, which are areas of general similarity in the type, quality, and quantity of environmental resources.
Ecoregions have been developed and are being used to study the place dependency of environmental processes, including anthropogenic transformations of the land surface. Ecoregions are also the basis for reporting on the status and trends of land cover and land cover change.
Information and links to downloadable maps and datasets for Level III and IV ecoregions, listed by state. Ecoregions are areas of general similarity in the type, quality, and quantity of environmental resources.
Terrestrial Ecoregions of the World (TEOW) is a biogeographic regionalization of the Earth's terrestrial biodiversity. Our biogeographic units are ecoregions, which are defined as relatively large units of land or water containing a distinct assemblage of natural communities sharing a large majority of species, dynamics, and environmental ...
Ecoregions are identified by analyzing the patterns and composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity (Omernik 1987, 1995). These phenomena include geology, landforms, soils, vegetation, climate, land use, wildlife, and hydrology.
The definition, delineation, and history of ecoregions are intertwined. For the sake of brevity, an ecoregion is defined herein as a land area that varies in size from a few hectares to thousands of square kilometers and has a unified climate, geology, topography, soil, potential natural vegetation, and predominant land use (for examples, see ...
Ecoregions are areas that have similar climate, geology, and soils. These abiotic (non-biological) factors determine what plants and animals can live in the ecosystem. Even though two places might be far apart, if they are part of the same ecoregion, we can predict they will have similar species.
Ecoregions are geographic regions of the world that indicate the distribution of ecosystems (see “ Terrestrial Ecosystem ”) and plant and animal communities. They have been variously defined according to the specific purpose of specific regionalization approaches.
