Selection and survival of Greater Sage-grouse nests and broods in the Bi-State region of California and Nevada
공공데이터포털
Resource selection functions (RSF) and associated maps are often used by managers to guide conservation actions (Crawford et al., 2020; Pratt and Beck, 2021; Saher et al., 2022). However it is important to move beyond designating important habitat solely based on species occupancy or use. Incorporating demographic measures such as reproductive success will provide increased power and detail for ranking habitat for management priority, particularly across multiple life stages and large spatial extents (Gibson et al., 2016; Pratt and Beck, 2021; Stephens et al., 2015). We provide a quantitative approach to differentiate productive habitats supporting high selection and survival from areas of maladaptive selection where selection and survival are misaligned at large spatial scales.

Landscape variables informing selection and survival of Greater Sage-grouse nests and broods in the Bi-State region of California and Nevada
공공데이터포털
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 not the result of value extraction, but rather field-collection such as date, fate, and age (in days) of the nest or brood. Ultimately, the locations were removed from these tables as sage-grouse are considered to be a sensitive species.

Time-varying greater sage-grouse habitat selection and survival categories in the Bi-State region of California and Nevada
공공데이터포털
We used movement and demographic data to simultaneously evaluate habitat selection by sage-grouse across multiple seasons, and measures of survival during key reproductive life stages (nesting and brood-rearing) to identify priority habitat by linking resource selection to demographic performance. We calculated and mapped composite selection and survival indices across the Bi-State Distinct Population Segment (DPS) to differentiate productive habitat that supported high selection and survival compared to areas of maladaptive selection where selection and survival were misaligned. We then reclassified the indices into categorical rasters representing different classes of selection (high, moderate, low, non-habitat) and survival (high, moderate, low, and very low).
