Safeeq Khan of UC ANR among collaborators on forest treatments in the Sierra
Despite the challenges of an extremely dangerous fire season, including California's largest wildfire in 2022 (Mosquito Fire) impeding access and limiting operations, partners of the French Meadows Forest Restoration Project have wrapped up their fourth season of forest treatments in the critical headwaters of Tahoe National Forest. Safeeq Khan, Cooperative Extension specialist in water and watershed sciences with UC Agriculture and Natural Resources, is among the collaborators.
This season, project partners safely treated over 700 acres of federal land using a combination of mastication, mechanical thinning, hand thinning and prescribed fire. On adjacent private land, the American River Conservancy independently raised funds and treated 338 acres. Combined, this all-lands collaborative watershed management project has treated over 6,000 acres in just four seasons.
Work this season focused on areas most prone to wildfire ignition. The United States Forest Service treated over 200 acres with prescribed pile burns in and around the Talbot campground, improving the aesthetic quality of this important recreation area just north of French Meadows Reservoir. Although dry conditions limited the scope of prescribed burns this year, using fire as a management tool is a cost-effective way to maintain forest conditions that contribute to ecosystem resilience and human health and safety.
“Prescribed burns are a critical component of the partnership's ecological forestry model,” explained Edward Smith, forest ecologist and fuels manager with The Nature Conservancy. “Under ‘prescribed conditions' of wind, moisture and temperature, broadcast burning helps reduce the amount of tinder on the forest floor as well as fuel ladders that could otherwise carry wildfires into the tops of trees, protecting habitat for humans and diverse wildlife species. Fire also reduces brush and twigs to ashes that feeds the roots of trees and understory plants, protecting the soil and its microbial universe, making them more resilient to drought, insects and climate change.”
Mechanical thinning, hand thinning, and mastication operations continued in areas surrounding water research instrumentation, installed by the Sierra Nevada Research Institute at the University of California, Merced. Over the coming years, researchers will be assessing how vegetation changes in ecologically-based forest management affect water quantity in the local watershed.
“Optimal restoration of forested headwaters benefits from dedicated partnerships collecting scientific data,” said Khan, who is also an adjunct professor of civil and environmental engineering at UC Merced. “UC Merced is working to provide this dimension at French Meadows with strategic measurements and modeling.”
Perhaps the partnership's biggest success in 2022 was securing, via multiple grants, the remaining funding necessary to complete all the thinning operations defined in the original project plan. Since the project's inception more than six years ago, the partnership has operated under an innovative funding arrangement consisting of local, state and federal dollars combined with private donations.
“What has impressed me most about the French Meadows partnership is its commitment to see the project all the way through: start to finish,” said Tahoe National Forest Supervisor Eli Ilano. “With the new funding secured this year, we will be able to wrap up thinning operations, and turn our focus to managing and maintaining the land for the enjoyment of the public.”
American River District Ranger Mary Grim with the U.S. Forest Service added, “This partnership learns from each year to adaptively manage for resilient forests that benefit everyone. The French Meadows Project is a reminder of what can be accomplished with a shared sense of stewardship for our forests and natural resources.”
Fuels reduction work this season resulted in more than 1.066 million board feet of overstocked timber, which was brought to a local mill, with the revenue generated offsetting some of the restoration costs. Project partners also repaired over seven miles of roadway and culverts to reduce sedimentation.
“Under the threat of a second consecutive severe fire season, including the Mosquito Fire in our own ‘backyard,' the partnership diligently moved treatment activities forward and began discussions on how to sustain the project's benefits through long-term maintenance planning,” said Kerri Timmer, regional forest health coordinator with Placer County, who coordinates the stewardship agreement with the Tahoe National Forest.
The catalyst of the French Meadows Forest Restoration Project was the 2014 King Fire, which burned over 97,000 acres in the American River watershed, much of it at high intensity. Eager to reduce the risk to hydroelectric assets, water quality, and biodiversity from future high severity wildfires, Placer County Water Agency joined with Placer County, The Nature Conservancy, the United States Forest Service, American River Conservancy, Sierra Nevada Conservancy, and the Sierra Nevada Research Institute at the UC Merced, to form the French Meadows Partnership.
The project spans more than 22,000 acres of federal land, nearly 7,000 acres of private land, and is a test case for the partnership's effectiveness in improving fire resilience and the overall health of the watershed.

The Center for Ecosystem Climate Solutions is launching its Natural Climate Solutions Toolbox. The comprehensive suite of data and decision support tools are designed to aid UC Cooperative Extension academics, land managers, policymakers and scientists in adapting California wildland management for a changing climate.
On Sept. 29, Safeeq Khan, UC Cooperative Extension specialist and adjunct professor at UC Merced, Toby O'Geen, professor and UC Cooperative Extension specialist at UC Davis, and Mike Goulden, professor at UC Irvine, will demonstrate the Natural Climate Solutions Toolbox for UC ANR and other UC academics who are interested in climate change, wildfire and land management in range and forest lands. They will explain how the toolbox can be used to address clientele needs.
The demonstration and product launch will be held via Zoom from 9:30 to 11 a.m. on Sept. 29. To register, visit https://surveys.ucanr.edu/survey.cfm?surveynumber=37843.
All UC ANR and UC academics, nongovernmental organization representatives and related colleagues interested in climate change, wildfire and land management in range and forestlands are invited.
The NCS Toolbox is useful for a variety of goals, including habitat restoration, reducing wildfire severity, projecting impacts of disturbance or management on water and carbon, and valuing benefits of management. This one-stop-shop data hub includes metrics of management history, vegetation, carbon balance, water, fire, fuels and more.
In the demonstration, the CECS team will walk through the decision support tools and extensive data available in the toolbox and discuss how they may be used in exploring impacts of historical and future disturbance and management on a range of metrics, or planning and assessment of new fuel reduction and restoration projects.

Mechanical thinning of overstocked forests, prescribed burning and managed wildfire now being carried out to enhance fire protection of California's forests provide many benefits, or ecosystem services, that people depend on.
In a paper published in Restoration Ecology, researchers at UC Merced, UC ANR and UC Irvine reported that stakeholders perceived fire protection as central to forest restoration, with multiple other ecosystem services also depending on wildfire severity. Researcher Max Eriksson, lead author on the paper, noted that "forest restoration involves multiple fuels-reduction actions that were perceived as benefiting fire protection, with some also offering strong benefits to other ecosystem services such as air quality, wildlife habitat, soil retention and water supply."
The study showed that the total effect of an action such as mechanical thinning of forests aimed at reducing fuels includes not only the direct effect on reducing wildfire severity, but also secondary effects that improving fire protection has on benefits such as providing water and hydroelectricity for agriculture and communities across the state or storing carbon and reducing carbon-dioxide emissions from wildfire to the atmosphere. Fire management is therefore central to human well-being.
Across the western United States, researchers are addressing the huge challenge of transforming forest management from the historical goal of maximum resource extraction (e.g., timber production) to a paradigm built on multiple benefits, or ecosystem services.
The study involved a series of virtual workshops with natural-resource professionals, including forest managers, to understand their perceived effects of management actions on ecosystem services and the interactions of the various services. Eleven ecosystem services and nine currently used management actions were considered.
Safeeq Khan, co-author and UC ANR Cooperative Extension specialist in water and watershed sciences, adds, "Understanding both actual and perceived benefits provided by restoring overstocked forests is crucial to guiding the choice of management actions, public support, policy initiatives and investments by beneficiaries, i.e., monetizing ecosystem services."
UC Merced Professor and co-author Roger Bales points out that "reducing fuel loads is increasingly being recognized as an effective measure to transition our forests across the western United States from a destructive to a beneficial wildfire regime."
Bales adds, "Our research supports the perception that California's wildfire-vulnerable forests should primarily and urgently be restored to conditions that better regulate wildfire severity, and thus provide greater fire protection and other ecosystem-service benefits. Lower-severity wildfire is a natural and beneficial part of these ecosystems."
An important contribution of this study is the breadth of both ecosystem-service benefits and management actions considered. Study collaborator and ecosystem-service expert Benis Egoh, an assistant professor at UC Irvine, points out that, "This research recognized that given the complexity of forest ecosystems across the western United States, the investments required and the management constraints, increasing forest resilience requires a range of actions." She adds, "Accounting for perceived interactions of ecosystem services is key to multi-benefit valuation of restoration investments and to monetizing those benefits in equitable ways."

UC Merced's largest research grant in its 16-year history aims to improve agricultural and environmental water resilience. The new $10 million collaborative focuses on water banking, trading and improvements in data-driven management practices to arrive at a climate-resilient future in water-scarce regions of the United States.
The U.S. Department of Agriculture announced it is funding the wide-ranging effort from multiple institutions across three states through its National Institute of Food and Agriculture's Agriculture and Food Research Initiative on Sustainable Agricultural Systems. The coalition of researchers is led by UC Merced, joined by experts from UC Berkeley, UC Davis, UC Agriculture and Natural Resources, Utah State University, the New Mexico Water Resources Research Institute at New Mexico State University, the Public Policy Institute of California, Environmental Defense Fund, and the U.S. Geological Survey's Southwestern Climate Hub.
“There are a lot of challenges in balancing the needs of agriculture and ecosystems, and climate change and drought are only exacerbating difficult decisions about how to sustain water resources,” lead project director UC Merced Professor Joshua Viers said. “But our team of advisors, educators and scientists are eager to enable data-driven decision-making for securing a climate resilient future for our water-stressed regions.”
The partners in the USDA funded collaboration — Securing a Climate Resilient Water Future for Agriculture and Ecosystems through Innovations in Measurement, Management and Markets or SWIM — will focus on developing more robust, data-driven information systems for decision-makers such as land and water managers. SWIM is designed to provide objective measures of supply and demand, and incorporate drought forecasting and climate change trends.
The research and extension team, by working with local decision-makers, will improve the accuracy of measurement in water budgets, evaluate novel management strategies such as on-farm aquifer recharge, and evaluate water trading and markets to improve sustainable surface and groundwater use.
The SWIM project will work across disciplines and stakeholders, integrating research, extension and education in three testbeds with unique water policies and systems: Cache Valley, Utah; Mesilla Valley, New Mexico; and the San Joaquin Valley. All of them grow orchard crops and alfalfa, and all are in a drought. Like California, Utah is experiencing an unprecedented drought, where 99 percent of the state is in extreme or exceptional drought. And, like California, the physical and cultural geography of New Mexico is extremely diverse. Exploring all innovative avenues of water management is necessary for sustaining a future for agriculture and surrounding communities while balancing ecosystem needs across the west, Viers said.
SWIM's leadership plans such activities as workshops and field days to actively engage stakeholders, including the extension-grower networks of each state's university system, as well as land, water and ecosystem managers.
Researchers from UC Merced include Viers, professors John Abatzoglou, Tom Harmon, Teamrat Ghezzehei, Josué Medellín-Azuara and Colleen Naughton, UC ANR Extension Specialist Safeeq Khan, Chelsea Arnold, who oversees the CalTeach program through the School of Natural Sciences, and researchers Leigh Bernacchi, Max Eriksson and Nicholas Santos.
“The SWIM project aims at bringing the sustainability science from ‘silos' to impact by systematically engaging our stakeholders and clientele in the knowledge co-production and systems thinking,” said Khan, UC Cooperative Extension specialist in water and watershed sciences.
“The project will build on the existing work of UC ANR networks and academics in understanding the needs of growers, irrigation districts, and ecosystem managers and co-developing data and tools to help adopt and adapt climate-resilience strategies. Our emphasis is not only on producing science and decision-support tools, but also using the project as an opportunity for social learning, knowledge empowerment, science communication, and workforce development through extension and outreach.”
In addition to ongoing activity at UC ANR's Kearney Research and Extension Center, one of the testbeds in California will be the new UC Merced Experimental Smart Farm. Researchers will collect soil, water and crop data, track droughts, conduct water accounting and life-cycle assessments, and produce user-focused data and analysis there and in the other two regions.
“The western United States is experiencing declining surface water and groundwater, adding stress on all aspects of the social-hydrological system,” said co-investigator Sam Fernald, director of the New Mexico Water Resources Research Institute at New Mexico State University. “The lessons learned in this project will offer a blueprint for addressing future water challenges, not just in the West, but other locations worldwide facing similar water shortage issues.”
The researchers want to answer many pressing questions, such as how much the changing characteristics of multi-year droughts alter people's willingness to engage in water trading and banking as part of climate resilience efforts; whether drought early warning systems propel water trading; how ecosystem services can be maintained while adapting agricultural water management to anticipated extremes; what are the key drivers and barriers adopting or participating in water markets; and how new data and technology can reduce costs and barriers.
They will also look at how climate change impacts can be mitigated through a rainy-day storage option called managed aquifer recharge or MAR, as well as water trading at multiple scales and land-use planning so that agriculture and the environment can be sustained.
One key component of creating a sustainable future is through educational programming, one of the core activities of the grant. The Climate Adaptation Science Academy will give affiliated graduate students the jump on their careers as leaders in science and engineering by providing training in climate adaptation science, communications and complex systems problem solving.
“Expanding the reach of our program are transformational K-12 educational tools,” Viers said. “Educators and graduate students will develop curricular materials for AgSTEM education pathways reaching from rural, regional middle schools to the teachers serving underrepresented groups.”
The SWIM team plans to develop such tools as games that support computational thinking and decision-making, activities in which students learn about agriculture and careers in smart farming, and hands-on experiential learning.
As associate dean for research in the School of Engineering and the director of the campus's branch of the Center of Information Technology and Research in the Interest of Society (CITRIS and the Banatao Institute), Viers discussed the role of UC Merced in providing tangible solutions to pressing societal problems:
“It has been clear for some time that water scarcity is our new reality, and we know we need to do things differently,” he said. “This research award is the largest that USDA makes to universities, and it is clear that they believe UC Merced and our affiliates are the right team with the right ideas to help secure a climate resilient water future.”
