Distribution map

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).
