Passage: Much of Minnesota's northern forest underwent logging at some time, 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 (162,000 ha) of unlogged land. Although logging continues, regrowth and replanting keep about one third of the state forested. Nearly all of Minnesota's prairies and oak savannas have been fragmented by farming, grazing, logging, and suburban development.While loss of habitat has affected native animals such as the pine marten, elk, woodland caribou, and bison, others like whitetail deer and bobcat thrive. The state has the nation's largest population of timber wolves outside Alaska, and supports healthy populations of black bears, moose, and gophers. 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 largest number of breeding pairs of bald eagles in the lower 48 states, as of 2007, red-tailed hawks, and snowy owls. The lakes teem with sport fish such as walleye, bass, muskellunge, and northern pike, and streams in the southeast and northeast are populated by brook, brown, and rainbow trout.
