LONDON, April 2, 2025 — Willis, a business of WTW (NASDAQ:WTW), and The Nature Conservancy (TNC) have today announced a first-of-its-kind insurance policy that takes into account efforts to mitigate fire risk. Structured by Willis, the $2.5 million wildfire resilience insurance coverage has been developed for Tahoe Donner Association (Tahoe Donner), a private homeowners association in Truckee, California.
In collaboration with the Center for Law, Energy and the Environment (CLEE) at the University of California, Berkeley, the wildfire resilience insurance policy was developed and placed to demonstrate lower premium pricing and improved availability where ecological forest practices have taken place. Such techniques include tree thinning to improve the health and growth of the remaining trees and planned fires to clear out flammable vegetation, both proven to reduce wildfire risk and make forests healthier. Tahoe Donner has completed forest management projects over 1,520 acres since 2015.
Insurance policies written in areas benefiting from forest treatment have previously not accounted for risk reduction from forest fire mitigation. This new policy, covering 1,345 acres of Tahoe Donner’s forested and recreation land, has a 39% lower premium and 89% lower deductible than would have been the case without nature-based forest management.
With insurers increasingly declining to write and renew insurance in California and other states as wildfire risks and claims costs continue to rise, this groundbreaking nature-based solution provides a new and urgently-needed approach to managing wildfire risk.
David Williams, Associate Director, Alternative Risk Transfer Solutions, Willis, said: “The forest management work completed by Tahoe Donner, by removing fuel that could burn and leading to a lower fire risk, has considerably reduced the premium and deductible in this insurance policy.
“At a pivotal moment for California’s insurance market, Willis has worked across the industry to bring this solution to Tahoe Donner.”

“At a pivotal moment for California’s insurance market, Willis has worked across the industry to bring this solution to Tahoe Donner, placing the insurance with Globe Underwriting, in a positive step towards a more resilient and sustainable insurance industry.” Globe Underwriting (formerly Forest Re) is internationally recognised for excellence in forestry risk assessment and profiling and provided the essential empirical analysis to support the premium and deductible reduction.
Kristen Wilson, Lead Forest Scientist, The Nature Conservancy in California, said: “By placing this innovative insurance product, we hope to inspire other insurance underwriters to account for the benefit of thinning and prescribed fire and increase the implementation of this type of work more broadly.”
Dave Jones, Director of the Climate Risk Initiative, CLEE, UC Berkeley School of Law, and former California Insurance Commissioner, said: “Federal, state and local governments, homeowners, homeowners’ associations and businesses are doing the right thing to reduce wildfire risk and invest in nature-based forest management. The improved price and availability of this pioneering insurance policy demonstrate that home and business insurers can and should renew and write property insurance in California and elsewhere in the United States where forest treatment is undertaken.”
Annie Rosenfeld, Tahoe Donner General Manager, said: “Tahoe Donner has been tested with fires that have come to the borders of the community, and the forestry work did its job. It slowed the spread of the fire to give firefighters enough time to stop it from impacting our community. We are proud to be a leader in this field.”
This announcement comes amid a challenging insurance landscape in California and across the United States. Thousands of residents in the Pacific Palisades had their insurance non-renewed just weeks before the devastating Los Angeles wildfires. Hundreds of thousands of homeowners throughout California have had their insurance non-renewed over the last five years.
California's FAIR Plan, a state-created association of insurers for those unable to secure traditional private insurance, has seen a dramatic surge in policies, with wildfire risk-driven non-renewals a significant contributory factor, as residential policies increased by 123% and commercial policies by 161% between September 2020 and September 2024.
