This technical note provides a brief synopsis of proactive, linear fuel breaks as a tool for reducing negative impacts associated with large-scale wildfire in sagebrush ecosystems. The note summarizes what fuel breaks are designed to do, features of effective fuel breaks, specifications of common fuel break designs, and maintenance and management considerations based on a compilation of existing publications and practical lessons learned from past greenstrip and plant materials trials in the Great Basin. The purpose is primarily to provide practitioners with sufficient information to begin cooperative landscape planning efforts.
