Title: Fire Effects on Seedbanks and Vegetation in the Eastern Mojave Desert: Implications for Postfire Management

Project Proposal Abstract: It is generally thought that Mojave Desert plant communities are poorly adapted for recovery following fire, due to high mortality rates of annual plant seedbanks and low survival rates of perennial plants. However, there is relatively little data to support these assumptions, and most evidence is anecdotal. The lack of high quality, quantified information becomes problematic when large fires occur such as those during summer 2005, and decisions must be made regarding the expenditures of significant resources on Emergency Stabilization and Rehabilitation (ES&R) actions. Information is especially needed regarding the short-term (3-year) effects of fire on soil seedbanks to help determine if seedings are appropriate ES&R treatments in the Mojave Desert. Information is also needed on the longer-term (multi-decadal) effects of fire on vegetation to provide quantitative assessments that will help develop effective fire management plans. This proposed project will take advantage of a unique opportunity presented by the Hackberry Fire Complex that burned 70,736 acres of the Mojave National Preserve in the eastern Mojave Desert during summer 2005. Because seedbank responses immediately following fire are of particular interest, we have already established 6 study sites and collected initial seedbank and fire severity data on these plots. We are requesting funds to support the balance of our initial 3-year postfire sampling plan. Existing prefire vegetation, fuels, and surficial geology maps will allow us to correlate short-term fire effects with prefire conditions. In addition, ground-based burn severity data will be correlated with short-term fire effects. Burn severity plot data will also be used to evaluate the accuracy of BARC burn severity maps developed using remotely sensed satellite data. The new data we produce will also be integrated into the NPS Fire Ecology Assessment Tool (FEAT) database to facilitate future resampling and analyses. We therefore submit this proposal in response to JFSP AFP 2006-1-Task2 (Rapid Response for Past (2005) Fires), because this AFP is focused on collecting time-sensitive information on the effects of fire that occurred during the 2005 fire season, especially where prefire data are available to correlate with postfire effects.
