Title: Evaluating the Efficacy and Ecological Impacts of BAER Slope Stabilization Treatments on the Pot Peak/Deep Harbor Wildfire Complex

Project Proposal Abstract: Soil stabilization treatments, including seeding, fertilizing, and mulching, are often prescribed as part of burned area emergency response (BAER) to prevent and control surface soil erosion and protect soil and water resources until native vegetation recovers. However, the efficacy of these treatments for increasing organic soil cover and preventing soil erosion has not been well established. In addition, recent studies suggest that BAER seeding and mulching treatments may hinder recovery of native vegetation and introduce exotic weeds. We are requesting funding for research to study the efficacy and ecological effects of BAER seeding, mulching, and fertilization treatments following mixed and high severity wildfires on forest lands of the interior Pacific Northwest. Our proposed study area is the Pot Peak/Deep Harbor fire complex near Chelan, Washington, where wildfires burned 47,000 acres during the summer of 2004. We propose a field experimental approach to 1) test the efficacy of seeding and fertilization treatments for promoting high plant biomass and litter cover during the first two years following fire and 2) assess the effects of treatments on cover and diversity of native vegetation. Proposed deliverables include peer-reviewed publications of study results, conference and workshop presentations, and a monitoring plan for BAER treatment efficacy that can be incorporated into future BAER treatment plans. Study results and the monitoring plan will be presented through a combination of published reports, web-based resources, and local presentations to managers during the second year of the project.
