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.Estimating distribution and connectivity of recolonizing American marten in the northeastern United States using expert elicitation techniquesDonovanTerriKilpatrickWilliamMurdochJamesAylwardCodyBernierChrisKatzJonwildlifedistributionoccupancy modelingexpert opinionconnectivityamerican martenKnown presence2015-01-012018-01-01This is a shapefile of areas of known marten presence in the study area, which includes Vermont, New Hampshire, Maine, and upstate New York.
