Sage-grouse habitat areas divided into proposed management categories within Nevada and California project study boundaries.
HABITAT CATEGORY DETERMINATION
The process for category determination was directed by the Nevada Sagebrush Ecosystem Technical team. Sage-grouse habitat was determined from a statewide resource selection function model and first categorized into 4 classes: high, moderate, low, and non-habitat. The standard deviations (SD) from a normal distribution of RSF values created from a set of validation points (10% of the entire telemetry dataset) were used to categorize habitat ‘quality’ classes.
1) High quality habitat comprised pixels with RSF values < 0.5 SD.
2) Moderate > 0.5 and < 1.0 SD.
3) Low < 1.0 .
4) Non-Habitat > 1.5 SD.
