Sage Thrasher Core Areas - Tack et al. [U.S. Fish and Wildlife Service] {2023}
Description
These data represent core areas developed from models predictive of relative abundance for sagebrush obligate species. Cores represent the minimum area necessary to encompass the concomitant proportion of the species total abundance; for example, a 25% core represents minimum area necessary to encompass 25% of the total predicted relative abundance for a species. Spatial models were developed using stop-level Breeding Bird Survey count data (BBS) and spatially-referenced covariates including landcover, climate, topographic, and fire variables measured at scales from 120m to 6.4km. All models were fit using random forests.File-based data for download: https://www.sciencebase.gov/catalog/item/61fda578d34e622189cf8303
