Decreasing Forest Density Will Reduce Fire Risk, Build Climate Resilience
The Report: Improving the Health of California’s Headwater Forests
September 19, 2017 - SAN FRANCISCO - California needs to increase the pace and scale of efforts to improve the health of its headwater forests—the source of two-thirds of the state’s surface water supply. Management techniques including prescribed fire, managed wildfire, and mechanical thinning can help rebuild resilience in these forests and prepare them for a challenging future.
These are among the key findings of a report released on Monday by the PPIC Water Policy Center.
Decades of fire suppression have increased the density of trees and other fuels in headwater forests to uncharacteristically high levels and resulted in massive tree die-offs and large, severe wildfires. Improving forest health will require reducing the density of small trees and fuels on a massive scale.
This will require changes in the regulation, administration, and management of forests. Many of the recommended reforms in forest management can take place at low or no cost. But implementing them will require vision, determined leadership by state and federal officials, and the backing of an informed public.
“Actions to arrest the decline in forest health will take place far from urban centers,” said Van Butsic, a coauthor of the report and a forestry expert with UC Berkeley’s cooperative extension. “But all Californians will benefit through continued supplies of high-quality water, natural environments, forest products, and recreational landscapes.”
Changing the way forestry work is funded—and in some cases securing new funding—will also be needed to help expedite forest improvements. The authors suggest reforms that will enable the private sector and government agencies to use existing tools and funding opportunities more effectively and collaborate more easily on larger-scale management projects. One key recommendation is to find opportunities to combine revenue-generating timber harvesting with other management work to help offset the costs of efforts to improve forest health.
“Making forest health a top land management priority for public and private lands would be a critical first step in reversing the degraded condition of the state’s headwater forests,” said report coauthor Henry McCann, a research associate with the PPIC Water Policy Center.
The report, Improving the Health of California’s Headwater Forests, was supported with funding from the S. D. Bechtel, Jr. Foundation and the US Environmental Protection Agency. In addition to Butsic and McCann, the coauthors are Jeffrey Mount and Brian Gray, both senior fellows at the PPIC Water Policy Center; Jodi Axelson, a forest health specialist with UC Berkeley’s cooperative extension; Yufang Jin, an assistant professor in the Department of Land, Air, and Water Resources at UC Davis; Scott Stephens, professor of fire science and co-director of the Center for Forestry and Center for Fire Research and Outreach at UC Berkeley; and William Stewart, a cooperative extension forestry specialist and co-director of the Center for Forestry and Center for Fire Research and Outreach at the UC Berkeley.
The PPIC Water Policy Center spurs innovative water management solutions that support a healthy economy, environment, and society—now and for future generations. It connects timely, objective, nonpartisan research to real-world water management debates, with the goal of putting California water policy on a sustainable and constructive path. The center was launched in April 2015.
