The natural history of Minnesota covers the plant and animal species of 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 on delineating between the coniferous forest in the north-central portion and the Arrowhead, a temperate deciduous forest in the central and southeast, and the tallgrass prairie in the southern and western portions of the state. [1] The northern coniferous forests are a vast wilderness of pine and spruce trees mixed with patchy stands of birch and poplar.

Flora

Much of Minnesota's northern forest has been logged, leaving only a few patches of old-growth forest today in areas such as in the Chippewa National Forest and the Superior National Forest where the Boundary Waters Canoe Area Wilderness has some 400,000 acres (1,600 km2) of unlogged land. [2] Although logging continues, regrowth keeps about one third of the state forested. [3]

Flora listed as threatened on the United States Fish and Wildlife Service list of endangered species include the Prairie bush-clover (Lespedeza leptostachya), the Western Prairie Fringed Orchid (Platanthera praeclara), and Leedy's roseroot (Rhodiola integrifolia ssp. leedyi), and the Dwarf trout lily (Erythronium propullans). [4]

Historic (and modern) loss of habitat, as well as overharvesting, has affected some native mammals to the point of extirpation, including the bison (disappeared in the mid-1800s; the last bison was reported in southwest Minnesota in 1879; [5] a non-wild population exists in Blue Mounds State Park [6] ), cougar (though vagrant individuals are becoming more common), [7] wolverine, [8] and the boreal woodland caribou (extirpated from all the Lower 48). Whitetail deer and bobcats thrive; the state has the nation's largest population of wolves (specifically timber wolves) outside of Alaska, [9] and also supports healthy populations of black bears, [10] elk, Canada lynx, American martens, [11] fishers, and moose.

Located on the Mississippi Flyway, Minnesota hosts migratory waterfowl such as geese and ducks, and game birds such as grouse, pheasants, and turkeys. It is home to the largest population of bald eagles in the contiguous United States following a large increase in conservation efforts and breeding areas since 1989, with an estimated 30 active nests in the Twin Cities alone. [12] The red-tailed hawk thrives in Minnesota woodlands, swamps, and prairies, where rodent populations are high. [13] Although they do not nest in the state, snowy owls migrate to Minnesota from the arctic tundra to hunt voles, mice, and rabbits. [14] The number of snowy owls in the state in any given winter depends greatly on the winter conditions of the snowy owl's natural habitat, in areas such as Canada and Alaska.

The state fish, the walleye, is found in all parts of Minnesota. [15] The walleye fishing season begins on the second Saturday of May, the time of year when the fish begin spawning. Walleye are especially active on cloudy days and after sunset, as well as during the autumn, when they feed heavily to prepare for winter. They naturally reproduce in 260 lakes throughout the state, and are stocked in 1,300 other lakes by the Minnesota Department of Natural Resources. The lakes contain other sport fish such as smallmouth and largemouth bass, muskellunge, and northern pike, and streams in the southeast are populated by brook, brown, and rainbow trout. [16]

The Piney Woods is a temperate coniferous forest terrestrial ecoregion in the Southern United States covering 54,400 square miles (141,000 km2) of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. These coniferous forests are dominated by several species of pine as well as hardwoods including hickory and oak. Historically the most dense part of this forest region was the Big Thicket though the lumber industry dramatically reduced the forest concentration in this area and throughout the Piney Woods during the 19th and 20th centuries. The World Wide Fund for Nature considers the Piney Woods to be one of the critically endangered ecoregions of the United States. The United States Environmental Protection Agency (EPA) defines most of this ecoregion as the South Central Plains.

The Laurentian Mixed Forest Province, also known as the North Woods, is a forested ecoregion in eastern North America. Among others, this terminology has been adopted by the Minnesota Department of Natural Resources.

Aspen parkland refers to a very large area of transitional biome between prairie and boreal forest in two sections, namely the Peace River Country of northwestern Alberta crossing the border into British Columbia, and a much larger area stretching from central Alberta, all across central Saskatchewan to south central Manitoba and continuing into small parts of the US states of Minnesota and North Dakota. Aspen parkland consists of groves of aspen, poplar and spruce, interspersed with areas of prairie grasslands, also intersected by large stream and river valleys lined with aspen-spruce forests and dense shrubbery. This is the largest boreal-grassland transition zone in the world and is a zone of constant competition and tension as prairie and woodlands struggle to overtake each other within the parkland.

Lake Vermilion is a shallow freshwater lake in northeastern Minnesota, United States. The Ojibwe originally called the lake Onamanii-zaaga'iganiing, which means “the evening sun tinting the water a reddish color”. French fur traders translated this to the Latin word Vermilion, which is a red pigment. Lake Vermilion is located between the towns of Tower on the east and Cook on the west, in the heart of Minnesota's Arrowhead Region at Vermilion Iron Range. The area was mined from the late 19th century until the 1960s, and the Soudan Mine operated just south of the lake.

<span class="mw-page-title-main">Fauna of Saskatchewan</span>

The Fauna of Saskatchewan include several diverse land and aquatic animal species. From the multiplicity of invertebrates and vertebrates, two have been chosen as symbols of Saskatchewan. Cenozoic vertebrate fossils reveal the geological evolution of the interior plains and its prehistoric biogeography. Today, Saskatchewan's ecosystems range from the sub-arctic tundra of the Canadian Shield in north Saskatchewan to aspen parkland, the Mid-Continental Canadian forests in the centre of the province and grassland prairie. Fauna inhabit areas unique to their own specific and varied breeding, foraging and nesting requirements. With a large land and water area, and small population density, the ecoregions of Saskatchewan provide important habitat for many animals, both endangered and not. Naturalists observing wildlife have enumerated shrinking and growing wildlife populations. They advocate programs and methods to preserve or re-introduce endangered species and identify programs of control for outbreaks of wildlife populations. A broad diversity of wildlife habitats are preserved as parks and reserves protecting the feeding and breeding grounds of protected and indigenous fauna of Saskatchewan.

<span class="mw-page-title-main">Ecology of the Rocky Mountains</span> Ecology of the Rocky Mountain range in North America

The ecology of the Rocky Mountains is diverse due to the effects of a variety of environmental factors. The Rocky Mountains are the major mountain range in western North America, running from the far north of British Columbia in Canada to New Mexico in the southwestern United States, climbing from the Great Plains at or below 1,800 feet (550 m) to peaks of over 14,000 feet (4,300 m). Temperature and rainfall varies greatly also and thus the Rockies are home to a mixture of habitats including the alpine, subalpine and boreal habitats of the Northern Rocky Mountains in British Columbia and Alberta, the coniferous forests of Montana and Idaho, the wetlands and prairie where the Rockies meet the plains, a different mix of conifers on the Yellowstone Plateau in Wyoming, the montane forests of Utah, and in the high Rockies of Colorado and New Mexico, and finally the alpine tundra of the highest elevations.
