Summary

This shapefile was developed in a project that identified areas with potential habitat for priority amphibian and reptile species or that likely support a noteworthy diversity of reptile or amphibian species in the North Atlantic Landscape Conservation Cooperative (http://nalcc.databasin.org/pages/about-north-atlanticlcc) and Northeast Partners in Amphibian and Reptile Conservation (northeastparc.org) regions. Our approach spatially applied the Priority Amphibian and Reptile Conservation Area (PARCA) System Criteria and Implementation Guidelines (PARCA Guidance; Sutherland and deMaynadier 2012) to combine amphibian and reptile species occurrence data and spatial environmental variables to predict and map habitat clusters (draft PARCAs) [...]

Purpose

This shapefile is the result of spatially applying criteria in the Guidelines for Identifying Priority Amphibian and Reptile Conservation Areas (Sutherland and deMaynadier (2012). We combined priority species occurrence data and spatial environmental data with MaxEnt to develop species distribution models (SDM), weighted the SDMs with respect to conservation status, combined the summed and weighted SDMs with reptile and amphibian richness determined from range map data, and evaluted the resultant polygons for significantly clustered patches. State experts reviewed the polygons for omission and commission errors, and their suggestions were used to revise the polygon boundaries resulting in this shapefile. The shapefile is intended for conservation planning purposes to suggest potentially suitable habitat for priority reptile and amphibian species, as well as areas where species richness may be particularly high. The boundaries have not been field-verified but indicate the generalized extent of modeled polygons resulting from Getis-Ord hotspot modeling.
