Dataset Overview
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. Probability 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: 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 4 and table 4 in this publication (the map was based on the model averaged model).
- Purpose
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
