An ecoregion is a contiguous area characterized by well defined similarity in flora and fauna as well as geomorphology, climate and soils; ecoregions are generally relatively large geographic units on the order of 50,000 square kilometers or more. Ecoregions may be terrestrial or marine, and do not recognize any political boundaries or landscape alterations by humans. Generally an ecoregion is depicted by a geographic descriptor coupled with a biome identity, further articulating one or more specific climatic or dominant plant community appellations: for example, Chilean Mattoral or Madagascar Dry Deciduous Forests.
There are several alternative formal naming schemes for the Earth's ecoregions; one of the most widely used, developed by the World Wildlife Foundation, recognizes 867 separate ecoregions. Because of the very large scale of an ecoregion, the landscape is not monolithic, but may have pockets of ecological diversity; however, the ecoregion is defined by its preponderant vegetative, geological and meteorological composition. Correspondingly boundaries between regions are sometimes diffuse, resulting in a broad ecotone.
Chile has eight ecoregions that occur entirely or partly within its borders on the mainland and three ecorgions offshore:
Eastern Carpathian beech forestsLast Updated on 2014-07-08 14:27:50Primeval beech forests of the Carpathians are comprised of ten reserves are in the eastern Carpathian Mountains, five clustered in eastern Slovakia and southwestern Ukraine near the Polish border, and five in southwest Ukraine near the point the mountains pass into Romania. These forests, classified as substantially primeval by the United Nations, are situated between 47°56’12”N to 49°05’10”N and 22°11’23”E to 24°23’35”E.
1908: First Ukrainian forest Natural Reserve established in Stuzhytsia;
1920s: Several Ukrainian beech forests became Protected Areas;
1968: The Carpathian Biosphere Reserve created by Soviet Council decree 568;

Canadian Aspen forests and parklandsLast Updated on 2014-07-01 15:39:55
WWF Terrestrial Ecoregions Collection
The Canadian Aspen forests and parklands ecoregion stretches in an arc from the Manitoba/North Dakota border in the east to central Alberta in the west with a disjunct occurrence in northwestern Alberta crossing the British Columbia border in the Peace River area. The preponderance of this ecoregion is situated in Canada, with a very small element residing in the USA state of North Dakota.
This ecoregion is classified primarily as having a subhumid low boreal ecoclimate, which distinguishes this ecoregion from the warmer, drier areas to the south and the cooler boreal forests to the north. It also has a transitional grassland climate. Summers are brief and warm, and winters are cold and protracted. Mean annual temperature ranges from 0.5°C to 2.5°C; the mean summer temperature ranges from 13°C... More »
Ecoregions of Oklahoma (EPA)Last Updated on 2014-06-28 15:53:00
Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. By recognizing the spatial differences in the capacities and potentials of ecosystems, ecoregions stratify the environment by its probable response to disturbance (Bryce, Omernik, and Larsen, 1999).
Ecoregions are general purpose regions that are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources in the same geographical areas (Omernik and others, 2000).

Registan-North Pakistan sandy desertLast Updated on 2014-06-28 00:07:20The Registan-North Pakistan sandy desert is an ecoregion spanning southern Afghanistan; the extreme eastern portion of Iran; part of northwest Pakistan, covering a total land area of approximately 107,100 square miles. This ecoregion is classifed within the Deserts and Xeric Shrublands biome.
There is considerable vertebrate species richness within the Registan-North Pakistan sandy desert, although endemism among this group is only represented by five reptilian taxa.
Situated in the southernmost portion fo Afghanistan, the far east of Iran and along part of the northwest Pakistan border area, this ecoregion is an arid element of the palearctic landscape. The Khash Desert is a major feature ot the ecoregion.
The Registan-North Pakistan sandy desert includes:
Zohary’s Iranian steppes of Artemisietea herbae-albae iranica east of the Kuh-e Gamsidzai and the Kuh-e Palangan;... More »
