Outside Wisconsin the highland stretches northward in Canada through the Upper Peninsula of Michigan and the Canadian Shield in Northern Ontario and Quebec to Labrador and Hudson Bay.
The second highest elevation in the state of Wisconsin is found in the Northern Highland and it is Sugarbush hill which is in Forest County.
The most common trees of the Northern Highland are the Sugar Maple, Aspen, Basswood, Hemlock, and Yellow Birch, as well as Red and White Pine.
State and county forests also cover a significant part of the region, and only a small portion of the land is devoted to agriculture.
[4] The wildlife of the Northern Highlands includes whitetail deer, timber wolves, elk, moose, and bear.
