Dataset Overview

This 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). 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. Katz. 2018. Estimating distribution and connectivity of recolonizing American marten in the northeastern United States using expert elicitation techniques. Animal Conservation (doi:10.1111/acv.12417). See figure 5.

Estimating movement corridors between isolated core populations of the American marten using circuit theory. The results demonstrate the effectiveness of expert-opinion data at modeling occupancy for rare species and provide tools for planning marten recovery in the northeastern United States.
