Altering Sagebrush Landscapes with Fuel Breaks to Save Them from Wildfire

Linear fuel breaks have long been used to help suppress fire in the Great Basin, and thousands of miles of new fuel breaks may be constructed in coming years to protect sagebrush ecosystems, including greater sage-grouse habitat.

Greater Sage-Grouse Science (2015-2017): Synthesis and Potential Management Implications

At the request of the BLM, the USGS worked with federal and state agency partners to develop a report that synthesizes the scientific literature published since records of decision were completed for 2015 BLM/USDA Forest Service land use plan amendments for greater sage-grouse, and provides potential management implications of the science.

Annotated Bibliography: Research on Greater Sage-grouse since January 2015

The sheer number of scientific publications related to greater sage-grouse research can be a challenge for managers to navigate when updating plans for managing greater sage-grouse and sagebrush ecosystems. To assist in this process, the USGS reviewed and summarized scientific literature published since January 1, 2015.
