Ecology of Minnesota
From Wikipedia, the free encyclopedia
The Ecology of Minnesota covers many plant and animal species. The mid continental location of Minnesota 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 Big Woods deciduous forest of the southeast, and the northern boreal forest.[1]
[edit] Flora
Three of North America's biomes converge in Minnesota: prairie grasslands in the southwestern and western parts of the state, the Big Woods deciduous forest of the southeast, and the northern boreal forest.[1] The northern coniferous forests are a vast wilderness of pine and spruce trees mixed with patchy stands of birch and poplar. 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]
[edit] Fauna
While loss of habitat has affected native animals such as the pine marten, elk, and bison,[4] whitetail deer and bobcat thrive. The state has the nation's largest population of timber wolves outside Alaska,[5] and supports healthy populations of black bear 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 birds of prey including the bald eagle, red-tailed hawk, and snowy owl. The lakes teem with the sport fish such as walleye, bass, muskellunge, and northern pike, and streams in the southeast are populated by brook, brown, and rainbow trout.
