Den Site Characteristics and Kit Survival of American Marten in West Michigan
American marten (Martes americana) were extirpated from Michigan's Lower Peninsula by the early 1900s due to logging and fur trapping. In 1986, 36 marten were reintroduced to the Manistee National Forest (MNF), but the population has not grown as expected. We documented kit survival and identif...
