The American marten (Martes americana) is a North American member of the family Mustelidae, sometimes referred to as the pine marten. The name “pine marten” is derived from the common but distinct Eurasian species of Martes. It differs from the fisher (Martes pennanti) in that it is smaller in size.
The American marten is broadly distributed in northern North America. From north to south its range extends from the northern limit of treeline in arctic Alaska and Canada to northern New Mexico. From east to west its distribution extends from Newfoundland to California. In Canada and Alaska, American marten distribution is vast and continuous. In the western United States, American marten distribution is limited to mountain ranges that provide preferred habitat. Over time, the distribution of American marten has contracted and expanded regionally, with local extirpations and successful recolonizations occurring in the Great Lakes region and some parts of the Northeast The American marten has been reintroduced in several areas where extinction occurred
