Summary

Rasters representing Greater Sage-grouse (hereafter sage-grouse) survival indices and categories during the nesting, early brood, and late brood life stages. A higher pixel value corresponds to a better chance of survival. The four categories of survival are very low, low, moderate, and high. We have also included rasters representing source and sink habitats for sage-grouse. Habitat sinks occur in areas of maladaptive habitat selection, where there are relatively high levels of selection, but low chance of survival. Source habitats were defined as any pixel that supported both high selection and high survival for a given life stage. Importantly, a given pixel was only considered source habitat if it was not sink habitat in another [...]

Purpose

Greater sage-grouse populations are threatened by a range of disturbances and anthropogenic factors that have contributed to a net loss of sagebrush-dominant shrub cover in recent decades. Declines in greater sage-grouse populations are largely linked to habitat loss, and a key component of conservation and land use planning efforts for the species involves the continued monitoring and modeling of habitat requirements and suitability across its range. The Bureau of Land Management (BLM) is currently addressing the management of both sage-grouse and sagebrush habitat on BLM managed public lands throughout the western United States through a land use planning amendment and associated environmental impact statement (86 FR 66331). Over 25 percent of the present range wide distribution of sage-grouse is within Nevada and northeastern California and information on sage-grouse distribution and habitat requirements is important to guide appropriate management decisions. To address this need researchers with the U.S. Geological Survey worked with multiple state and federal resource agency partners to map sage-grouse distribution and produce example habitat management categories for these states based on more than a decade of location and survival data collected from marked sage-grouse.
