The U.S. Geological Survey is gearing up for a project across the Great Basin studying how effective fuel breaks are, simultaneously evaluating their ecological costs and benefits.
Fuel breaks like sandy roads or other barriers are intended to reduce fire size and frequency by slowing or altogether halting fire’s spread to the other side of the break. Still, questions remain about whether fuel breaks protect sagebrush and sage-grouse, the USGS said in a comments discussing the new research.
“We want to determine the extent to which fuel breaks can help protect existing habitat from wildland fires, paying particular attention to how such breaks affect sagebrush habitat, sage-grouse, and other sagebrush-dependent species,” the USGS said in a statement.
Additional information about the research can be found on the USGS site.
