| Downloadable | Corridor map | 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.
Read More | 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). Corr idors 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. Read More | 2015-01-01 to 2018-01-01 |

Read More | This is a raster map of American marten (Martes americana) distribution in the northeastern United States. The value of each pixel in the map is an estimate of the probability of marten occupancy. P robability values were calculated from an occupancy model based on expert opinion data. For details on the collection of expert opinion data, the modeling process, and the development of the distribution map, please see:

Estimating distribution and connectivity of recolonizing American marten in the northeastern United States using expert elicitation techniques. Animal Conservation (doi:10.1111/acv.12417). The shapefile may be useful for providing geographic context to the marten corridor map (also included as a dataset in this project; see figure 5 in the paper).
