Successful adaptive management hinges largely upon integrating new and improved sources of information as they become available. Updating management tools for greater sage-grouse (Centrocercus urophasianus, hereafter referred to as “sage-grouse”) populations, which are indicators for the large-scale health of sagebrush (Artemisia spp.) ecosystems in the Great Basin of North America, provide a timely example for this tenet. Recently developed spatially-explicit habitat maps derived from empirical data played a key role in the conservation of this species facing listing under the Endangered Species Act. The spatial data provided herein apply resource selection function parameters that informed published maps of seasonal and annual habitat suitability and management areas for sage-grouse across combined population management units in Nevada and northeastern California as identified by the Nevada Department of Wildlife (Coates et al. 2016), to a previously unmapped area of northeastern California spanning 1,169,765 hectares. These data can be mosaicked or merged by users within a geographic information system with previously published mapping products from Coates et al. (2016) to make a seamless product that extends across the extent of known sage-grouse range in northeastern California. Please refer to Coates et. al. (2016) for further details on methodology.
