Characteristics of American Marten Habitat: A Resource Selection Function for Michigan’s Northern Lower Peninsula
American marten (Martes americana) are typically associated with old growth coniferous forests. However, habitat use varies across their range and studies should consider possible variations within each population. Little is known about the resource selection and distribution of marten in Michigan’s...
