Corridors were estimated using a cost-distance approach. For details on the development of the map, please see: Aylward, C. M., J. D. Murdoch, T. M. Donovan, C. W. Kilpatrick, C. Bernier, and J.

Little information exists on current marten distribution and how landscape characteristics shape patterns of occupancy across the region, which could help develop effective recovery strategies. The rarity of marten and lack of historical distribution records are also problematic for region-wide conservation planning. Expert opinion can provide a source of information for estimating species–landscape relationships and is especially useful when empirical data are sparse. We created a survey to elicit expert opinion and build a model that describes marten occupancy in the northeastern United States as a function of landscape conditions.Corridor mapThis is a raster map of corridors of expected movement between known populations of American marten (Martes americana) in Vermont, New Hamphire/Maine, and upstate New York (Adirondack Mountains).
