Fifty Level II regions were created to allow for a narrower delineation of Level I areas. Three level I areas were not subdivided for level 2. [2] Level III subdivides the continent into 182 smaller ecoregions; of these, 104 lie partly or wholly with the United States. [1] [3] Level IV is a further subdivision of Level III ecoregions. Level IV ...
The Allegheny Highlands forests are a temperate broadleaf and mixed forests ecoregion located in a large part of the Allegheny Plateau physiographic province, including both unglaciated and glaciated portions, in Pennsylvania and New York within North America, [2] as defined by the World Wildlife Fund.
The ecoregion covers approximately 84,500 km2 (32,630 mi2). [2] It is about 72 percent forest and 23 percent agriculture. Coal mining is still active in the Pennsylvania, West Virginia, and Kentucky portions of the ecoregion, and in Appalachian Ohio to a lesser extent.
The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms, containing 867 smaller ecoregions. Each ecoregion is classified into one of 14 major habitat types , or biomes . In 2017 the WWF team revised ecosystem names and boundaries in the Arabian Peninsula, drier African regions, and Southeastern United States.
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 natural communities and species .
The Eastern Himalayan broadleaf forests are diverse and species-rich, with a great diversity (of oaks and rhododendrons in particular) and many endemic species including plants of Indomalayan, Indochinese, Himalayan, Eastern Asiatic and even Gondwanan origin. The ecoregion has two broad forest types: evergreen and deciduous.
The region is home to around 5 million people, with majority of it residing within the eastern half it. Population growth and suburban sprawl occurred in the seventies, and continues to rapidly increase. Every county saw growth from 1990 to 2000 and from 2000 to 2005. The region near Philadelphia is very densely populated, but population ...
