Wisconsin ecoregion map prepared by the U.S. Environmental Protection Agency. The list of ecoregions in Wisconsin are listings of terrestrial ecoregions (see also, ecosystem) in the United States' State of Wisconsin, as defined separately by the United States Environmental Protection Agency (USEPA), and the World Wildlife Fund.
Professor Lawrence Martin created a schema for dividing Wisconsin into geographical regions in his work "The Physical Geography of Wisconsin". [1] [2] Western Upland; Eastern Ridges and Lowlands; Central Plain; Northern Highland; Lake Superior Lowland; Three of these geographical provinces are uplands and two are lowlands.
Map of the Prairie Pothole Region of North America (U.S. Geological Survey, Northern Prairie Wildlife Research Center) Barringer Slough in Iowa, a remnant of the extensive prairie wetlands that once covered the region. The Prairie Pothole Region (PPR; French: Région des cuvettes/fondrières des prairies) is an expansive area of the northern ...
Brady's Bluff Prairie State Natural Area is a Wisconsin Department of Natural Resources-designated State Natural Area featuring a steep, southwest-facing bluff rising over 450 feet above the Mississippi River. Over 100 species of prairie plants have been found at this site.
The abiotic factors that environmental gradients consist of can have a direct ramifications on organismal survival. Generally, organismal distribution is tied to those abiotic factors, but even an environmental gradient of one abiotic factor yields insight into how a species distribution might look.
The shortgrass prairie is located on the western side of the Great Plains with the Colorado Rockies to its West and the mixed grass prairie to its East. The prairie extends to the eastern part of the Rocky Mountains to the West, up to Canada to the North, as far as Nebraska to the East, and as far as parts of Texas to the South. [14]
Chiwaukee Prairie is a 485-acre (1.96 km 2) prairie in Pleasant Prairie, Wisconsin managed by the Wisconsin Department of Natural Resources (about midway between Chicago and Milwaukee). It is located on Lake Michigan at the Illinois state line and includes grassy wetlands, wooded areas, and the Kenosha Sand Dunes at its northern tip.
In 1947, the American botanist and climatologist Leslie Holdridge classified climates based on the biological effects of temperature and rainfall on vegetation under the assumption that these two abiotic factors are the largest determinants of the types of vegetation found in a habitat. Holdridge uses the four axes to define 30 so-called ...
