Wildland Fires: Better Information Needed on Effectiveness of Emergency Stabilization and Rehabilitation Treatments

摘要

Wildfires burn millions of acres annually. Most burnt land can recover naturally, but a small percentage needs short-term emergency treatment to stabilize burnt land that threatens public safety, property, or ecosystems or longer-term treatments to rehabilitate land unlikely to recover naturally. The Department of the Interior (Interior) and the Department of Agriculture's (USDA's) Forest Service-the two departments that manage most federal land-spend millions of dollars annually on such treatments. GAO was asked to (1) describe the two departments' processes for implementing their programs, (2) identify the costs and types of treatments implemented, and (3) determine whether these treatments are effective.
