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.

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.Distribution mapThis is a raster map of American marten (Martes americana) distribution in the northeastern United States.
