Acknowledgments <br />Preparation of this report represents a true partnership <br />between Forest Service Research and National Forest Sys- <br />tems staffs. Much of the work of collecting, collating, antl <br />tabulating the information contained in this report was con- <br />ducted by research assistants J. Tenpas, K. Hubbert, and B. <br />Nelson. We could not have completed it without them. The <br />cooperation of the six regional Burn Area Emergency Rehabili- <br />tation (BAER) coordinators and many Forest BAER team <br />members was essential to the success of this project, and we <br />gratefully acknowledge their contributions. Funding for the <br />project was provided by the Forest Service, Watershed and Air <br />Staff, with additional contributions from the Rocky Mountain <br />and Pacific Southwest Research Stations. <br />Contents <br />Page <br />Introduction .......................................................... ......1 <br />USDA Forest Service Bum Area Emergency <br />Rehabilitation (BAER) History ................. ......1 <br />Problem Statement and Objectives ................. ......2 <br />Definitions ........................................................ ......2 <br />Literature Review ................................................. ......5 <br />Fire's Impact on Ecosystems ........................... ......5 <br />Fire Effects on Watersheds ......................... ......5 <br />Water Quality ............................................... ......8 <br />Surtace Erosion ........................................... ......8 <br />Sediment Yield and Channel Stability ......... ......9 <br />Mass Wasting .............................................. ......9 <br />Dry Ravel ..................................................... ....11 <br />Emergency Watershed Rehabilitation <br />Treatment Effectiveness ......................... ....11 <br />Hillslope Treatments .................................... ....11 <br />Channel Treatments .................................... ....20 <br />Road Treatments ......................................... ....21 <br />Methods ............................................................... ....21 <br />Bumed Area Report Data ................................ ....21 <br />Interview Survey .............................................. ....22 <br />Project Review Interview Form .................... ....22 <br /> Page <br />No Action Review Interview Forth .............. .....22 <br />Treatment Actions Interview Form ............. .....22 <br />Relative Benefits Interview Form ................ .....22 <br />Monitoring Reports ......................................... .....22 <br />Analysis Methods ............................................ .....22 <br />Bumed Area Reports and Interview Forms .....22 <br />Monitoring Reports ..................................... .....23 <br />Results ................................................................ .....23 <br />Overview of Data Collected ............................ .....23 <br />Fire Severity .................................................... .....23 <br />Erosion Estimates ........................................... .....26 <br />Hydrologic Estimates ...................................... .....27 <br />Risk Analysis .................................................. .....27 <br />Probability of Success .................................... .....29 <br />Cost of No Action/Alternatives ........................ .....29 <br />BAER Team Members .................................... .....30 <br />Monitoring Reports ......................................... .....30 <br />Treatment Effectiveness Ratings .................... .....36 <br />Hillslope Treatments ................................... ..... 36 <br />Channel Treatments ................................... .....37 <br />Road and Trail Treatments ......................... .....39 <br />Treatment Rankings ....................................... .....39 <br />Discusslon ........................................................... .....44 <br />BAER Assessments ........................................ .....44 <br />BAER Project Monitoring ................................ .....46 <br />Treatment Effectiveness ................................. .....47 <br />Hillslope Treatments ................................... .....47 <br />Channel Treatments ................................... .....52 <br />Road Treatments ........................................ .....53 <br />Conclusions ......................................................... ..... 53 <br />Recommendations .............................................. .....54 <br />References .......................................................... ..... 54 <br />Appendix A-Example Data and <br />Interview Forms ...................................... .....60 <br />Appendix B-Treatment Effectiveness <br />Summaries ............................................. .....74 <br />Hillslope Treatments ....................................... .....74 <br />Channel Treatments ....................................... .....79 <br />Road Treatments ............................................ .....83 <br />You may order additional copies of this publication by sending your mailing information in label <br />fore through one of the following media.
