The model for golden-winged warbler was acquired from Dolly Crawford (Ashland University), which was included in Chapter 3 of the 2012 conservation plan (Roth et al., 2012). Model was composed of cells of predicted Golden-Winged Warbler occurrence across the study region. The study region was determined by the expert opinion derived by the technical team regarding the core breeding populations of Golden-Winged Warbler presence and assigned to the Great Lakes Conservation Region and Appalachian Conservation Region. Within these areas, certain extents are recommended for Golden-Winged Warbler conservation, as they are priority species in those regions and do not promote the invasion of Blue-Winged Warbler, a known hybridization risk. Population location data was determined through estimates developed by the Partners in Flight, which uses extrapolation of the North American Breeding Bird Survey. Environmental data was used to represent the elevation, forest type and cover, tree communities, and distance to local Blue-Winged Warbler populations.
