Habitat similarity index (HSI) values for greater sage-grouse across their western range. HSI values represent the relationship of environmental values at map locations to the multivariate model of minimum requirements for sage-grouse defined by land cover, anthropogenic variables, soil, topography, and climate.
Habitat similarity index (HSI) values for greater sage-grouse across their western range. HSI values represent the relationship of environmental values at map locations to themultivariate model of minimum requirements for sage-grouse defined by land cover, anthropogenic variables, soil, topography, and climate.
We partitioned a Mahalanobis D2 model of sage-grouse habitat use into separate additive components each representing independent combinations of species-habitat relationships to identify and map range-wide ecological minimums for sage-grouse. We assumed the states delineations of priority areas capture higher quality habitat and larger numbers of sage-grouse populations across our study area. We randomly selected 1669 points from the priority areas and corresponding variables GIS datasets to calibrate models. We estimated distributions of our variables from 1000 iterative samples created by bootstrapping the calibration data. To better incorporate conditions in both large and small priority areas, we restricted...
