American Marten (Martes americana), a State Endangered mammal, lives in mature, dense conifer forests, mixed conifer-hardwood, and hardwood dominated forests, including hemlock, white pine, yellow birch, maple, fir, and spruce. Marten young are born in tree dens in late-March and April and are weaned when about 6 weeks old. To avoid potential take of dependent kits in suitable habitat, within the American marten range, do not cut trees between March 15 and May 31. See the species guidance document for guidance from the Wisconsin Trappers Association, Wisconsin Conservation Congress, and the Wisconsin DNR.
