Title: Vegetation Impacts of Recurring Fires on Sagebrush Ecosystems in Washington: Implications for Conservation and Rehibilitation

Project Proposal Abstract: Thousands of hectares of high quality shrub steppe burned in large fires in 2000 and 2007 in the Arid Lands Ecology (ALE) Reserve on the Hanford Reach National Monument. Extensive permanent vegetation monitoring plots were established throughout this area in the mid-1990s, and many of these plots were remonitored following the 2000 fire. In addition, rehabilitation efforts to control invasive species (e.g., Bromus tectorum) and establish native species took place following this fire. This combination of monitoring and rehabilitation treatments provide a unique opportunity to better understand the individual and cumulative effects of recurring fires in this landscape. These fires may have significantly altered the trajectory of vegetation recovery of these systems by removing dominant species and stimulating invasive taxa. We propose to resample these permanent plots to address key questions regarding the interactions of native vegetation, invasive species, rehabilitation actions, and repeated fires. The results of this study will inform immediate management decisions regarding present and future post-fire habitat rehabilitation measures on the ALE Reserve, the National Monument and other shrub steppe sites, and will provide a critical understanding of the long-term dynamics of these significant shrub steppe systems.
