American Martens in the Apostle Islands

This photo is part of our discovery of American martens on the Apostle Islands. Martens were reintroduced to the Apostle Islands by the State of Wisconsin in the 1950's, but were not seen after the 1960's. Using camera trapping over the past few years we detected American martens at 28 of 87 functioning camera trap sites on 5 of 13 monitored islands and documented the existence of American martens in APIS in Wisconsin for the first time in over 50 years.

The full documentation of this sighting is available at
