4.3.1.2. Summary of Impacts by Alternative

All alternatives utilize wildland fire to restore fire-adapted ecosystems and reduce hazardous fuels. Alternative C would result in the greatest potential for adverse impacts from human caused, unplanned ignitions due to increased access and additional travel routes under this alternative. Conversely, Alternative C would also result in the greatest beneficial impacts from active fuels management (i.e., this alternative allows the widest use of fuels treatments) and the greatest ability to employ fire suppression tactics, followed by alternatives A, D, and B respectively. Alternative C includes the greatest amount of mechanical fuels treatments by acreage (60,000 acres), followed by alternatives A and D (30,000 acres each), and Alternative B (5,000 acres), resulting in beneficial impacts to fire and fuels management by reducing fuels and thereby the potential for fire spread and severity. Fire suppression restrictions (e.g., prohibiting the use of heavy equipment on fragile soils) increase the potential for wildfire spread in the short term and may increase the need for stabilization and rehabilitation as more wildfires occur. However, intensive fire suppression that reduces the natural role of fire in the ecosystem may result in large catastrophic wildfires in the long term that require more-intensive stabilization and rehabilitation activities. Under all of the alternatives, implementing the BLM Emergency Stabilization and Rehabilitation standards in the DOI Interagency Burned Area Emergency Response Guidebook (DOI 2006b) and BLM Burned Area Emergency Stabilization and Rehabilitation Handbook (BLM 2007b) would prescribe activities that would allow rehabilitation of areas following a wildfire and reduce the potential for future fires in burned areas.
