Abstract
Sagebrush rangelands are shrinking across the western U.S., due to pressure from a variety of factors including development, invasive species, and altered fire regimes. The past few decades has seen an increase in fire size and frequency within the sagebrush steppe, largely fueled by invasive annual grasses. A case study from the Twin Falls Bureau of Land Management District of southern Idaho analyzes the costs of fuel break implementation and wildfire, finding that properly maintained fuel breaks could provide significant economic benefits to land managers in the Great Basin.
