	Terrestrial ecoregion - Wikipedia, the free encyclopedia
		Ecoregions are defined by World Wildlife Fund as "relatively large units of land or water containing a distinct assemblage of natural communities and species, with boundaries that approximate the original extent of natural communities prior to major land-use change".
		Terrestrial ecoregions are land ecoregions, as distinct from freshwater ecoregions and marine ecoregions.
		Ecoregions are classified by biome type, which are the major global plant communities determined by rainfall and climate.

	Terrestrial ecoregion Information - TextSheet.com
		The terrestrial ecoregions are, in ecology, those ecoregions of land, as distinct from those in the oceans and fresh water.
		This conflicts slightly with traditional usage of terrestrial as a synonym for "terran" ("of Earth" in general, whether land or oceans).
		There are 867 terrestrial ecoregions organized into 8 major ecozones.

	Terrestrial ecoregion - Simple English Wikipedia
		In ecology, a terrestrial ecoregion is a certain area of land which is different from the area near it.
		Or for example, an ecoregion could be a tropical forest It would have warm temperatures all day, a lot of rainfall all year, a huge river crossing, and a very organic soil.
		Marine ecoregions are similar, but are located in the oceans or fresh waters.

	Conservation Ecology: Biodiversity, urban areas, and agriculture: locating priority ecoregions for conservation
		These ecoregions tend to be concentrated in the southeastern United States, California, and, to a lesser extent, the Atlantic coast, southern Texas, and the U.S. Midwest.
		Ecoregions are defined as relatively coarse biogeographic divisions of a landscape that delineate areas with broadly similar environmental conditions and natural communities.
		For example, although our analyses identify ecoregions in which human land use and endemic species overlap, finer analyses within the ecoregion may reveal that the ranges of those species are, in fact, well protected, with urban and agricultural lands occurring elsewhere in the ecoregion.

		Only those ecoregions with levels of richness and endemism that are outstanding at global or regional (i.e., biogeographic realm such as the Neotropics) scales were elevated to extinction-prone status for this analysis in order to identify the most critical areas for species loss.
		Ecoregions are also categorized within the context of a suite of protection, restoration, and forestry recommendations deemed appropriate for each.
		Thus, most of the extinction-prone forest ecoregions are found in tropical regions and the continuing loss of forests and natural habitats in these extinction-prone ecoregions will be the single biggest contributor to the loss of species diversity on this planet over the next few decades.

	Eco Regions Quick Reference
		World Wildlife Fund Ecoregions represents global terrestrial and freshwater ecoregions defined as relatively large areas of land or water in the world that share a large majority of their species, dynamics, and environmental conditions.
		It contains the terrestrial habitats and some freshwater habitats of the Global 200 ecoregions, a collection of the Earth's most outstanding and diverse terrestrial, freshwater, and marine habitats--areas where the Earth's biological wealth is most distinctive and rich, where its loss will be most severely felt, and where we must fight the hardest for conservation.

	Ecoregion (Site not responding. Last check: 2007-10-08)
		Another way of looking at an ecoregion is a "recurring pattern of ecosystems associated with characteristic combinations of soil and landform that characterise that region" (Brunckhorst, 2000).
		The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tend to be distinct from that of other ecoregions.
		The use of the term ''ecoregion'' is an outgrowth of a surge of interest in ecosystems and their functioning.

	Terrestrial Ecoregions -- Southern Andean Yungas (NT0165)
		This ecoregion is extremely fascinating from a biogeographic perspective, as it contains what may be the last of the isolated ‘evergreen’ forests resulting from Quaternary glaciations (Nores 1992).
		The Southern Andean Yungas are loosely bordered to the east by the Chaco, and tightly interdigitated to the west with Bolivian Montane Dry Forest, spanning southwestern Bolivia and northwestern Argentina (Olson et al.
		This ecoregion essentially forms a mesic habitat that lies between two much drier habitats: the Chaco to the east, and the higher Puna to the west (Olson et al.

		"of Earth", which is also the root of "terrestrial", e.g.
		Some, such as Hugo De Garis make the distinction that those who want to leave Earth or destroy it may be of terrestrial origin but are not in fact Terran.
		That distinction seems to be derived from earlier usage of "terran" by many science fiction authors as a synonym for "earthling" or "human" or "terrestrial" - most notably in the context of alien encounters with humans.

		Ecoregions define distinct ecosystems that share broadly similar environmental conditions and natural communities; as such, they make more sense for priority-setting efforts than do political units such as countries or provinces.
		Terrestrial Ecoregions of the Indo-Pacific offers a comprehensive examination of the state of the Indo-Pacific's biodiversity and habitats, moving beyond endangered or charismatic species to quantify for the first time the number of mammal and bird species, including endemics, in each ecoregion.
		The analysis concludes with a set of ecoregions that deserve immediate attention and also highlights ecoregions that are still in relatively pristine condition.

		Forest ecoregions comprise 86 of the 136 terrestrial ecoregions.
		At the time of writing, 232 ecoregions were identified, comprising 136 terrestrial, 35 freshwater, and 61 marine ecoregions (Olson and Dinerstein, 1998: 509).
		Forest ecosystems account for 6 of the 12 terrestrial MHTs, and these 6 forest MHTs contain nearly two-thirds of all terrestrial ecoregions.

		In general, biodiversity is focused in the forest canopy, although five layers typify the forest structure: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory.
		Among the 13 terrestrial major habitat types, the largest number of ecoregions by far falls within the TSMF (50 ecoregions or 35 per cent of all terrestrial ecoregions).
		The most diverse terrestrial ecoregions occur in the Western Arc forests of the Amazon Basin, with close rivals in the Atlantic Forest ecoregion of Brazil, the Choco-Darien ecoregion of northwestern South America, and Peninsular Malaysia and northern Borneo forest ecoregions.
