Title: Invasive Species Response to Fire and Post-Fire Rehabilitation Following the 2005 School Fire, Umatilla National Forest

Project Proposal Abstract: Invasive species are spreading rapidly on rangelands and in dry forests and pose serious ecological and economic threats to our environment. Managers are very concerned about weed spread following the 2005 School Fire that burned 21,000 ha of state, private and Umatilla National Forest lands, in WA. Severely burned areas within the fire were treated with various mulching and seed treatments to control erosion and improve native re-vegetation. Weeds follow disturbances such as fire and harvesting because of the removal of existing vegetation, increase in exposed soil, and increased forest floor light levels. The effects of mulching and seeding treatments on soil and native vegetation recovery and the spread of invasive species are not well documented or understood. This proposal addresses JFSP AFP 2006-1 Task 2. A rapid response protocol was used to establish 84 plots shortly after the fire to prevent the loss of this critical, time-sensitive data. We propose additional sampling across the range of pre-fire treatment conditions (thinning and prescribed burning), burn severities and post-fire treatments (seeding and mulching) to describe and analyze soil and vegetation recovery in treated and untreated areas. Multitemporal high-resolution remotely sensed images will be used to detect burn severity and produce a map from which managers can better monitor invasive species spread. Results will be shared with local managers via annual reports and two workshop/field trips, at BAER Team Leader Meetings and at various trainings coordinated with collaborating research and technology transfer projects. We will contribute to a proposed GTR and produce two peer-reviewed publications. These results combined with other ongoing monitoring efforts will provide much-needed information about the effectiveness of pre-fire fuels and post-fire rehabilitation treatments to mitigate fire effects and weed response and will help managers make better decisions in the future.
