Summary

We monitored Greater Sage-Grouse (Centrocercus urophasianus; hereafter, Sage-Grouse) nests and various habitat characteristics at the nest locations near Susanville in northeastern California, crossing over into northwestern Nevada. We employed a before-after-control-impact (BACI) experimental design to account for spatiotemporal heterogeneity in the system and to derive estimates of relative change in survival parameters. Sage-Grouse nest survival decreased after the Rush Fire but decreased more in the burned area relative to the unburned area. Although female Sage-Grouse continued to occupy burned areas, nest survival was reduced from 52 percent to 19 percent. Using a BACI ratio approach we found that nest survival decreased approximately [...]

Purpose

Increased wildfire frequency and associated replacement of sagebrush (Artemisia spp.) with invasive annual grasses contribute to declines of Greater Sage-Grouse (Centrocercus urophasianus; hereafter, Sage-Grouse) populations across the Great Basin. However, little is known about wildfire effects on Sage-Grouse nest-site selection and nest survival, which can influence population persistence. The primary objective of this study was to evaluate the effects of the Rush Fire on Sage-Grouse nest survival using before (2007-2009) and after (2015-2018) data collected from a population of Sage-Grouse occupying the border of northeastern California and northwestern Nevada.
