Reducing fuel loads among a host of preservation tools

Readers should beware of ideological or political statements based on “overwhelming science” when the writer doesn’t provide responsible sources. A good example is Brett Haverstick’s March 24 guest opinion that claims science doesn’t support the management and restoration of forests in the face of catastrophic wildfire, insects and disease. There is plenty of peer-reviewed research that strongly supports the role of active management in improving and maintaining the health and resiliency of our forests.

The National Insect and Disease Map, developed through rigorous scientific standards, indicates 60 to 80 million acres of forests are at risk of insects and disease and are in need of treatment. In 2012, the Science-Based Risk Analysis Report, available at forestsandrangelands.gov, determined that “experience with fuels treatment projects has demonstrated the value of fuels reduction to reduce wildfire suppression costs and protect land and resources.” The 2013 Nature Conservancy field guide for dry forest restoration cites more than 150 scientific sources outlining the need for active forest management on this forest type.

Fire is natural to forested landscapes in the West. Most people understand the difference between natural low-intensity fires and catastrophic, stand-replacing crown fires. In a natural situation, wildfire can promote natural regeneration and fuels reduction. But in their current overcrowded, unhealthy condition, catastrophic wildfires can devastate forests, sterilize soils, reduce water quality, destroy wildfire habitat, and threaten human lives and property. Observational studies, experimental studies and computer modeling studies (Fulé et al. 2001a and 2001b; Pollet and Omi 2002; Finney et al. 2003; Schoennagel et al. 2004) suggest that the risk of crown fire can be lowered if fuel loads are reduced, small-diameter trees are removed and ladder fuels are minimized.
