This report is a synthesis of post-fire emergency hillslope stabilization treatment effectiveness information that was written to provide guidance for future post-fire treatment selection and use. It builds on an earlier synthesis, Evaluating the Effectiveness of Postfire Rehabilitation Treatments (Robichaud and others 2000) (fig. 1). Since that publication, the effectiveness of emergency postfire hillslope treatments have been evaluated in several scientific studies and treatment monitoring reports prepared by Burned Area Emergency Response (BAER) and Emergency Stabilization and Rehabilitation (ESR) teams. In addition, our knowledge of how environmental factors impact treatment effectiveness and the development of new post-fire hillslope treatment products and application techniques has grown. The objective of this document is to synthesize that new information in a format that is easily accessible by post-fire assessment teams and land managers.
