Demographics and habitat use of Greater Sage-Grouse in wildfire-affected habitats in Oregon.


July 2013 - June 2017


Southeast Oregon contains part of one of the largest contiguous sage-brush steppe habitats remaining within the extant range of Greater Sage-Grouse. In the summer of 2012, several wildfires included more than 1 million acres of Oregon sage-grouse habitat within their perimeters. The primary objectives of this study are to:
1. Determine basic life-history parameters and vital rates including nesting propensity and reproductive success, and adult female survival in wildfire-altered landscapes.
2. Describe movement patterns, home range size, and habitat use of female sage-grouse in wildfire-altered landscapes.
3. Link habitat use data collected at an appropriate temporal scale to individual life-history parameters including female survival, nest success and brood survival.
Accomplishing these objectives will inform the prioritization of areas for post-fire habitat rehabilitation and restoration, and help identify areas requiring further protection and/or active management to reduce risk of wildfire and ensure sage-grouse population persistence.
