Natural History Of Minnesota
The natural history of Minnesota covers many plant and animal species in the U.S. state of Minnesota. The continental climate and location of Minnesota at the physiographic intersection of the Laurentian and the Interior Plains influences its plant and animal life. Three of North America's biomes converge in Minnesota: prairie grasslands in the southwestern and western parts of the state, the eastern temperate deciduous forests in the east-central and the southeast, and the coniferous forest in the north-central and northeast. Ecoregions An ecoregion is an area uniquely defined by environmental conditions and natural features. Ecoregions in Minnesota were largely influenced by the unique glacial history, geology, soil type, land use, and climate of the state. The United States Environmental Protection Agency, Minnesota Department of Natural Resources, and World Wildlife Fund maintain separate classifications of the state's ecoregions. Although different, they generally agree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minnesota Department Of Natural Resources
The Minnesota Department of Natural Resources, or Minnesota DNR, is the agency of the U.S. state of Minnesota charged with conserving and managing the state's natural resources. The agency maintains areas such as state parks, state forests, recreational trails, and recreation areas as well as managing minerals, wildlife, and forestry throughout the state. The agency is divided into six divisions - Ecological & Water Resources, Enforcement, Fish & Wildlife, Forestry, Lands & Minerals, and Parks & Trails. History Efforts to conserve Minnesota's wildlife began as early as 1876, with a forestry association established to protect the state's timber resources. However, those efforts became futile as the industry took over and people sought the money that could be made on the land. Over time, there were other attempts to control the destruction of resources, but most only had effects on what was done to public land, such as the Land Commission established in 1885. In 1911 the Minnesot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hardwood
Hardwood is wood from dicot trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual growth rings, but these may be absent in some tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing as a result. The dominant feature separating "hardwoods" from softwoods is the presence o ...

Door Peninsula
The Door Peninsula is a peninsula in eastern Wisconsin, separating the southern part of the Green Bay (Lake Michigan), Green Bay from Lake Michigan. The peninsula includes northern Kewaunee County, Wisconsin, Kewaunee County, northeastern Brown County, Wisconsin, Brown County, and the mainland portion of Door County, Wisconsin, Door County. It is on the western side of the Niagara Escarpment. Well known for its cherry and apple orchards, the Door Peninsula is a popular tourism destination. With the 1881 completion of the Sturgeon Bay Ship Canal, the northern half of the peninsula became an island. Limestone outcroppings of the Niagara Escarpment are visible on both shores of the peninsula, but are larger and more prominent on the Green Bay side as seen at the Bayshore Blufflands. Progressions of dunes have created much of the rest of the shoreline, especially on the east side. Flora along the shore demonstrate plant ecological succession, succession during periods of low ...

Lacustrine Plain
A lacustrine plain or lake plain is a plain formed due to the past existence of a lake and its accompanying sediment accumulation. Lacustrine plains can be formed through one of three major mechanisms: glacial drainage, differential uplift, and inland lake creation and drainage. Lake plains can have various uses depending on where and how they form. Over time, in regions where a lake once existed, as water drains or evaporates from the lake, the deposited sediments are left behind, resulting in a level plain of land where the lake once existed. The soil of the plain may constitute fertile and productive farmland due to the previous accumulation of lacustrine sediments; in other cases, it may become a wetland or a desert. Background Lacustrine plains are plains formed when lakes filled with sediments are drained. There are several reasons why drainage might occur, but in all cases the water in the lake is lost, leaving behind a level land of sediments. The resulting plain is an a ...

Green Bay (Lake Michigan)
Green Bay is an arm of Lake Michigan, located along the south coast of Michigan's Upper Peninsula and the east coast of Wisconsin. It is separated from the rest of the lake by the Door Peninsula in Wisconsin, the Garden Peninsula in Michigan, and the chain of islands between them, all formed by the Niagara Escarpment. Green Bay is some long, with a width ranging from about ; it is in area. At the southern end of the bay is the city of Green Bay, Wisconsin, where the Fox River enters the bay. The Leo Frigo Memorial Bridge (formerly known as the Tower Drive bridge) spans the point where the bay begins and the Fox River ends, as the river flows south to north into the bay. Around mid-bay are Sturgeon Bay and the Peshtigo River. The Sturgeon Bay serves the city named after the bay as a shortcut for large ships to use to bypass the Door Peninsula, while the Peshtigo River serves Peshtigo and Crivitz. Locally, the bay is called the Bay of Green Bay to distinguish it from the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolf River (Fox River)
The Wolf River is a longU.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed December 19, 2011 tributary of the Fox River in northeastern Wisconsin in the Great Lakes region of the United States. The river is one of the two National Scenic Rivers in Wisconsin, along with the St. Croix River. The scenic portion is long. The river and its parent the Fox River and associated lakes are known for their sturgeon which spawn every spring upstream on the lower river until blocked by the Shawano Dam. The river flows through mostly undeveloped forestland southerly from central Forest County in the north to Lake Poygan (west of Lake Winnebago) in the south. The lake is part of the Winnebago Pool of lakes fed by both the Fox and Wolf Rivers. The Fox-Wolf basin is usually considered to be a single unified basin and the rivers themselves may be referred to as the ''Fox-Wolf River system''. The river is known in the Menominee lang ...

Big Woods
Big Woods refers to a type of temperate hardwood forest ecoregion found in western Wisconsin and south-central Minnesota. "Big Woods" is a direct translation of the name given to the region by French explorers: . Trees and native vegetation The dominant trees are American elm, basswood, sugar maple, and red oak. The understory is composed of ironwood, green ash, and aspen. The Big Woods would have once covered in a diagonal strip long and wide. Today most of this region has been cleared for agriculture and urban development. Remnant and secondary stands of Big Woods remain in parks and other protected areas. Native vegetation based on soils information (note the bright green color) from the Natural Resources Conservation Service of the United States Department of Agriculture shows the historic extent of oak savannas in the Big Woods region (See accompanying pie chart, below).
