Microbiologist, Hydrologist, Soil Microbiologist, and Geomorphologist, respectively, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Glendora, Calif. Abstract: Raindrop impact is a major agent of soil erosion, and any reduction in its effectiveness reduces sediment production from burned watersheds. A chaparral soil treated with heatshock fungi in three combinations was compared to sterile soil to test the ability of postfire heat-shock fungi to diminish raindrop impact erosion. Two to three times as much sediment was detached from sterile soil as from any of the three fungal treatments. A 1-month incubation period was sufficient to allow all fungal treatments to resist raindrop impact.

Postburn Insect Fauna in Southern California Chaparral1
Professor of Biological Sciences, California State Polytechnic University, Pomona, California 91768. Abstract: Extremely little is known about succession of insects in postfire chaparral. This 4-year postfire study in the San Gabriel Mountains of southern California showed that pollen-nectar feeders and predatory insects can be very abundant beginning the first spring after a burn. Annual plant...
متن کاملMortality of resprouting chaparral shrubs after a fire and during a record drought: physiological mechanisms and demographic consequences.
We examined postfire regeneration of chaparral shrubs during an intense drought. This study focused on the demography and physiology of shrub species that resprout from a basal lignotuber following fire. We found significant levels of resprout mortality when intense drought occurred in the year following fire during the period of shrub recovery. Three of the seven sampled resprouting species ha...
متن کاملPredicting postfire erosion and mitigation effectiveness with a web-based probabilistic erosion model
The decision of where, when, and how to apply the most effective postfire erosion mitigation treatments requires land managers to assess the risk of damaging runoff and erosion events occurring after a fire. To meet this challenge, the Erosion Risk Management Tool (ERMiT) was developed. ERMiT is a web-based application that uses the Water Erosion Prediction Project (WEPP) technology to estimate...
متن کاملErosion Risk Management Tool (ERMiT) – A Probability-based Erosion Prediction Model
After wildfires, land managers must assess the potential for increased flooding, erosion, and sedimentation, and the increased threat these effects may pose to people, structures, and valued resources. A Web-based Erosion Risk Management Tool (ERMiT) has been developed to predict surface erosion from postfire hillslopes, and to evaluate the potential effectiveness of various erosion mitigation ...
متن کاملEffects of Fire on Chaparral Soils in Arizona and California and Postfire Management Implications1
Wildfires and prescribed burns are common throughout Arizona and California chaparral. Predicting fire effects requires understanding fire behavior, estimating soil heating, and predicting changes in soil properties. Substantial quantities of some nutrients, particularly nitrogen and phosphorus, are lost directly during combustion. Highly available nutrients released during a fire are deposited...
