Summary

These data are the input tables for the habitat selection and survival models. The tables are the result of extracting values from rasters to both 'used' and 'available' locations; 'used' refers to an observation of a sage-grouse nesting or brood rearing, 'available' is a randomly-generated location proximal to a paired 'used' location. For these locations, we extract values from multiple rasters expressing landscape characteristics such as landcover (such as sagebrush, annual grass, or shrubs, expressed as a percentage), height of sagebrush, distance to water features, distance to anthropogenic features, and topographic transformations (such as slope, heat load index, and roughness). There are also some values in the table that are [...]

Purpose

Management decisions often focus on habitat selection of marked individuals without considering the contribution to performance in selected habitats. Because habitat selection is not always adaptive, understanding the link between habitat selection and demographic performance is critical to management decisions. Mapping both selection and demographic performance for species of conservation concern can help guide population-scale conservation efforts.
