CalFresh Healthy Living, UC and UC Master Gardeners partner with nonprofit MORE in El Dorado County
A nonprofit serving adults with intellectual and developmental disabilities in El Dorado County, MORE has found kindred spirits in helping their clients live fuller and healthier lives – the staff and volunteers of University of California Master Gardeners and CalFresh Healthy Living, UC.
Since 2018, these programs – both affiliated with UC Agriculture and Natural Resources – have helped enrich the lives of about 60 clients at MORE, which offers services ranging from independent-living skills development to job training and placement.
“This is exactly the kind of partnership that we like to make with the community,” said MORE CEO Susie Davies, who has been with the Placerville-based organization for 40 years. “This has just been incredible; our people have learned above and beyond what we could even have imagined in nutrition and gardening.”
The three-party partnership, which Davies calls a “win-win-win,” offers a course that combines gardening and nutrition lessons, as well as a new cooking and food safety-focused class developed by educator Cailin McLaughlin in collaboration with MORE staff.
During one session, MORE clients enjoyed preparing a “plant part salad,” following a botanical lesson on the edible components of plants – fruits, roots, leaves, seeds and stems. “It was fun to cut the celery and broccoli,” said Jared (first names are used to protect privacy). “I like pouring the sauce in.”
“I liked everything about creating the salad,” said Deanne, another participant.
“MORE is the dream site, the best you could ever hope to go to, with the programming and the clients always being lovely and really just being down for anything,” said McLaughlin, a CalFresh Healthy Living nutrition educator at the Central Sierra UC Cooperative Extension office. “It's just a really cool place to be.”
CalFresh Healthy Living, UC is one of the organizations in California that teaches nutrition to people eligible for SNAP (Supplemental Nutrition Assistance Program). UC Davis administers the SNAP-Ed grant and UC Cooperative Extension educators deliver the lessons throughout the state.
‘Part of our MORE family'
Through the gardening and nutrition program, clients learn and apply their skills in the garden and greenhouse at the MORE facility and in the nearby Sherwood Demonstration Garden maintained by UC Master Gardeners of El Dorado County.
“The participants get a chance to harvest, plant, pull weeds and learn about integrated pest management, both in the vegetable garden and in the orchard,” said Tracy Celio, the local UC Master Gardeners program manager who worked with former CalFresh Healthy Living, UCCE educator Miranda Capriotti to develop the program.
“It's a very good program,” said Tony, a MORE client. “I can learn things.”
While experiencing the pride in bringing fresh produce to their home or to the MORE kitchen for use in the meal service, the clients are also taking away nutritious and healthy recipes. Jordan Postlewait, director of community access programs at MORE, said participants now know how to use ingredients from the garden to create dishes such as tomato salsa and fruit salad.
“They've taken the recipes that Cailin has given them and they go home and serve their whole group home what we had made for a snack,” Postlewait said. “They are paying attention to what they're eating.”
As a result of this awareness and knowledge of nutritious foods, Davies said that MORE clients are healthier, more energized and alert, and ready to learn. She is quick to credit the expertise and enthusiasm of McLaughlin, CalFresh Healthy Living, UCCE program coordinator Mariana Garcia, and the UC Master Gardeners staff and volunteers.
“They have the same dedication and commitment to excellence in their preparation for every session as our staff,” Davies said. “They just became part of our MORE family.”
“I like seeing Cailin and Tracy and all the staff who are my friends,” said Kenion, a MORE client.
Cooking lessons create possibilities for kitchen time, jobs
In April, two groups, each composed of six people, began participating in a new five-session course combining nutrition, food safety and basic cooking techniques. Each two-hour session included a nutrition lesson, a physical activity and time in MORE's commercial kitchen.
“It was fun getting in the kitchen and learning how to prepare my own meals,” Jared said. “I learned how to safely use a small skillet.”
Another participant, Kyle, said he uses the recipes to cook for his roommates. “I liked learning new cooking skills and recipes,” he said.
McLaughlin adapted a youth-oriented healthy eating curriculum, approved for use by CalFresh Healthy Living, UC, and tailored it for adults at MORE.
“The whole goal is to get them closer to an independent living circumstance, where either they can live in a group facility or have their own apartment – and knowing how to cook and identify healthy recipes is a huge component of that,” McLaughlin explained.
The guided kitchen experiences – and equipment like plastic safety knives – not only benefit the participants but also give their family members reassurance and confidence to include them in meal preparation.
“We've actually been asked by staff at MORE, and also by clients' parents, where we got the knives, because they would like to have their family member in the kitchen with them, if they can do it safely,” McLaughlin said. “They didn't know things like safety knives existed; they didn't know you could adapt a silicone food guard to keep them from burning themselves on a burner.”
In addition to enhancing the clients' family time, the cooking lessons could also set them up for future employment. Davies said she is in talks with a local chef about establishing a culinary training for the clients.
“This cooking program could be a preparation program for them to be involved in the culinary training program,” she said. “That's what we're really excited about.”
McLaughlin added that, for future sessions of the cooking and food-safety series, past participants have expressed interest in serving as kitchen aides and mentors.
Partners nurture clients' relationships with nature, community
Empowering clients with new skills and fostering a sense of ownership of the garden are both cornerstones of the partnership programs. Beginning in 2019, participants from MORE each adopted a tree in the Sherwood Demonstration Garden orchard to monitor and nurture.
“Almost every time they come to the garden, we check those fruit trees,” Celio said. “The trees are doing so many things throughout the year, so they're following the cycle: they watch the leaves drop; they watch the fruit come in; they see what a freeze does to their tree; they see what pests do to their tree.”
The participants experience the challenges of gardening – from managing rabbits and squirrels to coping with the loss of a pear tree due to disease – as well as its many joys.
“I liked seeing the butterflies and different plants; the butterflies drink from the bushes,” said Jen, a MORE client. “My favorite thing is the rose garden.”
At the same time, the clients have built strong relationships with the core group of UC Master Gardener volunteers and the dozen or so “vegetable garden crew” volunteers. Celio stressed that the garden programs, which were recently recognized by the statewide UC Master Gardeners program with a Search for Excellence Award, are truly collaborative.
MORE participants often bring their own ideas; one man, for example, became interested in composting and worked with MORE staff to establish a worm bin at the MORE facility garden.
“Every time I see that client, he will tell me how the worms were doing and he'll tell me how healthy the plants are that are growing next to the worm bin,” Celio said, adding that he also worked at a table during a MORE fair, teaching other clients and their family members about vermiculture.
Advocating for the greater good of the community is central to another CalFresh Healthy Living, UC collaborative project at MORE, in partnership with Stanford University's Our Voice initiative. Using an online tool and app, 12 clients have been taking photos and sharing feedback on their health and wellness experience at MORE, specifically about their walking trail. With that information, they are building a case to make the path safer and more enjoyable.
Responding to their feedback, along with the other partnership programs that are building vital skills and community, demonstrate to MORE's clients that they are appreciated and respected.
“The request from the people that we serve is that they want to be seen, they want to be heard, and they want to be valued by other community members,” Davies said. “And this is really showing them that they are valued and being seen and heard.”

University of California Cooperative Extension, 4-H Youth Development Program in Santa Clara County partnered with multiple community organizations to hold a 4-H Nature Explorers Day Camp at Escuela Popular Bilingual Academy in East San Jose from July 17 to July 21.
Organizers wanted to reach more participants this year than they had in the inaugural 2022 camp, so they structured the program for different K-8 grade levels to attend on different days. 79 campers participated, which was a 130% increase over the number of campers last year.
“Everything we did during the week was focused on environmental science,” said Susan Weaver, 4-H Regional Program Coordinator. “We partnered with Project Learning Tree, UC Environmental Stewards, UC Master Gardeners and CalFresh Healthy Living, UC– as well as community agencies related to the natural environment.”
Numerous activities engaged the youths such as field trips; demonstrations; and sessions themed around trees as habitats, birds and bugs, and being “leaf detectives.” 4-H Adult Volunteer, Laura Tiscareno, took charge of the hands-on Project Learning Tree sessions. Craft time included making nature-themed wind chimes and spinning paper snakes.
Bilingual teen camp counselors guided small groups of students for the duration of the day camp. In situations where the adult facilitator did not speak Spanish, teens translated information into Spanish for students with less English confidence.
“These kids call me ‘teacher' and it's awesome,” said Rodrigo, one of the counselors. “The camp benefits me a lot because I connect with children and in the future, I can even be a teacher if I wanted to.”
Another counselor, Andrea, learned about communication. “It's a bit different with kids at different age levels,” she said. “Since we had kindergarten through eighth grade, we had to switch our tactics from grade to grade so that they would understand us and we'd be able to understand them. Also learning how to bond with them so that they would pay more attention.
One highlight of the week was a field trip for third through eighth graders to the Master Gardeners location at Martial Cottle Park, where students learned about vermicomposting and made their own individual countertop worm habitat and composter.
Campers especially enjoyed the interactive demonstrations. “My favorite part is going on all the field trips because we went to a garden, and we've been catching worms and doing stuff about worms,” said one student. “It's really fun going on trips.”
Another camper said, “Something I would like to change about camp is having more time here.”
The program culminated in a Nature Camp Festival at Escuela Popular in partnership with community agencies. Youth enjoyed games, meeting reptiles, outdoor science activities, arborist crafts, a “Rethink Your Drink” table to make a fresh fruit drink, tamales, a nacho bar and more.
Representatives from the Silicon Valley Wildlife Center discussed animals that live in local neighborhoods and how the Center supports people to keep the animals safe. Victor Mortari of Vexotic Me talked about and showed snakes, spiders, scorpions, and other creatures, making the kids squeal while learning about them. As a fun added bonus, 4-H Community Educator Zubia Mahmood arranged to have a local team come to teach soccer skills as a healthy living activity.
The event increased the youth's interest in environmental education and involved Latino youth and adults who are new to 4-H – representing a community that has not historically benefited from the 4-H program. The teen teachers also increased their leadership and career readiness skills; post-camp surveys showed that all the teen counselors see 4-H as a place where they can be a leader and help make group decisions. Some campers noted in the survey that they wanted the camp to be every day, all summer!
National 4-H funded the camp in 2022 and 2023, allowing organizers to provide meals, T-shirts, water bottles and other items to foster belonging and promote healthy living. Community partners, crucial to the program's success, included the Boys and Girls Club of Silicon Valley, Escuela Popular Bilingual Academy, Silicon Valley Water and Silicon Valley Wildlife Center.

Nutrition Policy Institute researcher influenced obesity research, SNAP-Ed evaluation
Young people across California and the U.S. enjoy healthier, more nutritious food options at school, thanks to the contributions of Gail Woodward-Lopez, who retired on July 1 as the associate director of research at the Nutrition Policy Institute, a part of University of California Agriculture and Natural Resources.
Woodward-Lopez officially joined UC ANR in 2015, when she and other researchers at the Atkins Center for Weight and Health at UC Berkeley merged with NPI. But her association with UC ANR goes back much further, as her work at CWH was always directed by UC Cooperative Extension academics – including the research that paved the way for California's “junk food ban” in schools.
Two bills, signed in 2005, set nutrition standards in California for “competitive foods”– the items sold in vending machines and from food service a la carte (as opposed to federally subsidized school meals). That legislation – which inspired similar policy changes across the country – was informed by the work of Woodward-Lopez and her colleagues, who had looked at the financial impact of establishing those standards.
“Our study was so pivotal that I literally had people calling me from the floor of the Senate or the Assembly when they were debating that legislation,” recalled Woodward-Lopez.
Changing perceptions of population weight gain
Originally intending to pursue a career in neurobiology, Woodward-Lopez found that lab work didn't suit her temperament. Seeking to work more directly on social issues, she embarked on a public health path, with an emphasis on nutritional aspects that incorporated her interest in biological sciences.
Woodward-Lopez's early work focused on a challenge that was just beginning to catch the attention of researchers: the rapid rise in the Body Mass Index (BMI) among the U.S. population. In tracing the causes of this epidemic, she and her colleagues shifted academic and public attention toward the host of environmental factors that contribute to weight gain – instead of focusing exclusively on an individual's choice to eat healthy and be physically active.
“Two decades ago, Gail led groundbreaking work to identify the determinants of obesity when child obesity was emerging as a public health concern,” said Nutrition Policy Institute Director Lorrene Ritchie. “While we and other researchers across the nation were working on generating more evidence to inform action, she had the vision that we could use a variety of existing data – from trends to trials – to point to the main causes.”
Many of the researchers' conclusions, which were published in the 2006 book “Obesity: Dietary and Developmental Influences,” stand to this day.
Helping to set the identity and agenda of the Center for Weight and Health when it was founded in 2000, Woodward-Lopez moved policy and practice beyond educational approaches and public awareness campaigns. As she noted: “No one thinks sugar-sweetened beverages are good for you.”
“Education alone is not going to work if people do not have access to the healthy foods and opportunities for physical activity, if they're not safe in their neighborhoods, or if they can't afford the healthy options,” she explained.
Given her seminal role in the field, Kaiser Permanente sought out Woodward-Lopez as a “thought partner” on the organization's community-based obesity prevention programs and school health work.
“Gail brought deep rigor and expertise, of course, but also a super-practical, community-focused perspective to our work,” said Loel Solomon, professor of health systems science at the Kaiser Permanente Bernard J. Tyson School of Medicine. “Her integrity and values around health equity were evident in everything we did together, and our communities are so much the better for it.”
Elevating and enhancing CalFresh Healthy Living
At the Nutrition Policy Institute, the focus of Woodward-Lopez's work has been refining the evaluation and delivery of SNAP-Ed, the educational component of the Supplemental Nutrition Assistance Program (commonly referred to as “food stamps”). Known in California as CalFresh Healthy Living, SNAP-Ed represents the largest single source of ongoing funding for nutrition and physical activity promotion in the state – outside of the WIC program which serves women, infants and young children.
“CalFresh Healthy Living can really impact millions of people,” Woodward-Lopez said. “For county health departments, this is one of their main sources of funding and provides the backbone for everything else they do in nutrition and physical activity.”
But given the variety of interventions implemented by health departments in response to local needs, determining the efficacy of those efforts is a daunting task. Woodward-Lopez and her NPI colleagues have been instrumental in devising creative approaches that help pinpoint the most effective public health measures.
For example, NPI researchers found that combining school policy changes with increased opportunities for physical activity during the school day was the best strategy to encourage student fitness. They discovered that reductions in nutrition programs during the COVID-19 pandemic disproportionately affected communities of color. And they also continue to emphasize that interventions need to be tailored to the specific cultural and political conditions within a community.
“I think in all of the work we do, we try to come up with those practical applications – what does this mean for communities? How can we do this differently? How are our findings actionable?” Woodward-Lopez said.
Her contributions toward the evaluation of California Department of Public Health SNAP-Ed have impressed and inspired Lauren Whetstone, chief of CDPH's Research, Evaluation and Strategic Alignment Section, Nutrition Education and Obesity Prevention Branch.
“Gail and her team have elevated the quality of our evaluation work and the evaluation support that we provide to local health department grantees,” said Whetstone, who has worked with Woodward-Lopez for nearly a decade. “Gail contributed substantially to statewide SNAP-Ed evaluation as well, again working collaboratively to ensure high quality evaluation. Our work is all the stronger due to Gail's dedication to excellent SNAP-Ed evaluation.”
To the benefit of the field and community health, Woodward-Lopez said she plans to remain engaged in her life's work.
“I'd really like to get more involved in policy through advocacy and through doing things like writing letters to the editor or social media commentary,” she said. “I already have some ideas for some editorials I want to write.”
And while she looks forward to spending more time with loved ones, traveling, and pursuing her interests in art and music, Woodward-Lopez will remain a guiding voice for advancing public health.
“Gail's leadership in public health nutrition – even after she retires – is a testament to her dedication,” Ritchie said. “She not only has contributed to sustainable changes in California and nationally, she has been a mentor to me and so many others in the field who will strive to continue her legacy.”
People interested in supporting Woodward-Lopez's legacy and the ongoing work in health and nutrition can donate to NPI's Student Fellowship, which provides students from underrepresented groups the opportunity to work on NPI research and be mentored by NPI researchers.

During summer swarming season, homeowners urged to check for signs of Formosan subterranean termite
In the lottery of troublesome termite infestations, “Roger,” a Rancho Santa Fe homeowner, hit the jackpot (a pseudonym is used to protect his privacy). In 2021, his house in San Diego County was identified as home to only the fourth documented colony of the Formosan subterranean termite (Coptotermes formosanus) in California.
“FST is one of the most destructive urban pests in the world,” said University of California, Riverside entomologist Chow-Yang Lee, affiliated with UC Agriculture and Natural Resources through the campus' Agricultural Experiment Station. “It's also the only termite species listed in the ‘100 of the World's Worst Invasive Alien Species.'”
Endemic to East Asia, this termite is now established in many tropical and subtropical regions, including across the American South. Annually, its infestation costs more than $4 billion in control measures and damage repairs of structures in the U.S.
FST was first discovered in California in La Mesa (San Diego County) in 1992, and it was rediscovered in that city in 2018. Another infestation was reported in Canyon Lake (Riverside County) in 2020. And then, the following year, Roger received his surprise.
“Imagine being in your kitchen looking at your drywall and it's totally normal and then the next day there's a four-inch hole there and you're like ‘What the heck is that? Who put their elbow into the drywall?'” he recalled.
FST colonies can reach millions of individuals
Roger hired a pest control company, Green Flash Pest Control, which sprayed a powerful liquid termiticide in the soil around the house. But the termites – workers, soldiers and winged “alates” – continued to appear. The company tried a second application of soil treatment. But, again, the termites kept popping up.
“We were deeply concerned about the potential damage these termites could cause to the home since these invasive termites are extremely destructive,” said Eric Veronick, director of operations at Green Flash. “Unfortunately, there isn't a whole lot of information available on the behavior and management of this termite in California.”
The company called upon Siavash Taravati, a UC Cooperative Extension urban Integrated Pest Management (IPM) advisor based in Riverside.
“Some colonies are aerial, meaning that they are formed above the ground with limited or no connection to the soil – in such cases, soil treatment using contact insecticides may not be very effective in managing these termites,” Taravati said. “Furthermore, contact insecticides usually kill a much smaller portion of the colony when compared to termite baits.”
To make matters worse, once FST is established in an area, there have been no records of successful eradication anywhere in the world, according to Taravati. He added that a major reason why the Formosan subterranean termite is so destructive is the enormous size of their colonies.
“Their colonies can reach millions of individuals, versus most native subterranean species that reach a few hundred thousand individual termites per colony,” Taravati explained.
This termite, through its sheer numbers, can turn the wood in a structure into a “spongy kind of cake,” in Taravati's words. More than 10 pounds of wood in a house can be eaten by a mature colony each month. The financial hit for a homeowner can be substantial, up to tens of thousands of dollars – not to mention the increased risks to safety.
“Anything from studs to rafters to door frames and window frames – everything is going to be compromised, if the termites are left unchecked. And then, as soon as we have a major stress on the building, let's say there's a big storm or an earthquake – there's a high risk of at least part of the building collapsing,” said Taravati, who also noted that, unlike California native subterranean termite species, FST can attack and kill live trees and plants.
“These termites can be a nightmare,” he said.
Summer is ‘swarming season' for FST
Since the Rancho Santa Fe case in 2021, four more colonies have been documented, in La Mesa again and also in Highland Park, Hollywood Hills and La Verne (the latter three in Los Angeles County). Taravati said it's possible that FST has been spreading via structural lumber or potted plants and soil.
And even if a colony appears to be eliminated at a certain locale, Taravati noted, there is always the chance that part of the colony survives or more colonies of termites already have been established in nearby locations, as a result of swarming termites from the originally infested property.
Although nominally “subterranean,” certain members of an FST colony grow wings and fly to nearby locations to establish new colonies. These winged alates are also called swarmers because of their behavior during the “swarming” season, when termites mate and reproduce.
For the Formosan subterranean termite, that swarming season in California is late May through early August, so now is the time for homeowners and building managers in southern and central California to keep an eye out for those winged termites.
“If you experience a termite swarm in your house, contact a pest management professional and keep some termite samples in a Ziploc bag in the event you need to send the samples to UC Riverside for morphological and DNA-based identifications,” said Lee, who added that it's a good idea to periodically check your structure for signs of infestation, such as wood damage or shelter tubes (mud tubes).
Lee said FST swarmers have a lighter colored body compared to the dark color of native subterranean termites and the orange-brown body of drywood termite swarmers (see this flyer for additional identification information).
Following an especially wet winter, there's a chance California could see more FST infestations, as this termite generally requires moist environments to thrive, Lee added. He recommends that concerned community members seek professional advice.
“Do not attempt to control an FST infestation by yourself,” Lee said. “This is not your typical native Californian subterranean termite species; they are highly destructive, and you want to intercept the problem with the right strategy before it's too late.”
Homeowner: ‘I owe them my house'
In Roger's case, Taravati enlisted the help of Lee and his UC colleague, Greg Kund. They made multiple visits to inspect the home and analyze the situation – going “above and beyond,” according to Roger.
At Lee's suggestion, they used a caulk gun to insert a gel-like experimental bait into the wall where the termites were coming out. Once spread and passed on to the other nestmates, the product – which contains a chitin synthesis inhibitor (a type of insect growth regulator) – interrupts the termites' development so they are unable to properly molt and replace the short-lived “workforce” of foragers and soldiers. The colony eventually collapses and is eliminated.
“Generally speaking, IGRs are much more effective, but they require more patience,” Taravati explained. “You're not going to see the results the next day, or two-three days. You're going to see the results in a few weeks – but when you see the results, it's massive.”
And that's exactly what Roger and Green Flash Pest Control saw.
“Soon after their bait application, the termites stopped emerging from the walls and that gave us and the homeowner a big sigh of relief,” Veronick said. “I appreciate their expertise and dedication in helping us get rid of this destructive pest."
Roger said he is immensely grateful to the UC team.
“They were fantastic; I owe them my house,” he said. “They were super gracious and helpful and responsive and – ultimately, the thing I care most about – they were effective; they fixed the problem. Here we are two years later and – knock on wood, or maybe I should knock on something else! – everything is good.”
Lee also credited Taravati for bringing his knowledge and “can-do” attitude to communities across Southern California.
“He is highly knowledgeable and always able to come up with feasible solutions,” Lee said. “We need good Cooperative Extension urban IPM advisors like Siavash who could provide good advice and bring solutions to the stakeholders, be they homeowners or pest management professionals.”
Taravati said community members need to maintain their vigilance and urges them to download and share the FST flyer that includes identification tips and contact information. He said they are always free to e-mail him with their concerns and photos of suspected FST – not only to help stop the spread of the pest but to expand scientific understanding.
“This termite is so new to California – even for us, as researchers. Despite being in La Mesa since the 1990s, it wasn't until 2020 when these termites were detected in other places, including Riverside and Los Angeles counties,” Taravati explained. “All of us need to learn more about this pest and closely monitor the behavior of this pest.”

Besides starting fires for the sake of research, Luca Carmignani, UC Cooperative Extension fire advisor for San Diego, Orange, Los Angeles, and Riverside counties, has started leveraging his connection to local UC campuses by providing opportunities for hands-on learning.
Early one morning in May, students and staff from UC Irvine and UC Riverside gathered at the South Coast Research and Extension Center to collect data for their own research projects. South Coast REC, located in Irvine, is part of a statewide network of research and education facilities operated by UC Agriculture and Natural Resources.
In one area of the field, graduate students picked leaves and twigs from dried shrubs, carefully placing them in a device that measures moisture content. In another area, a postdoctoral scholar set up a device that records levels of particulate matter, carbon dioxide and other air pollutants emitted by a fire.
Tirtha Banerjee, professor in the Department of Civil and Environmental Engineering at UC Irvine, coordinated the field day with Carmignani. The two first connected as members of iFireNet, an international network of networks that connect people to fire research, when Carmignani was a postdoctoral researcher at UC Berkeley.
Now, the two are collaborating to help environmental science and engineering students realize the potential of their research interests.
Jacquelynn Nguyen, a Ph.D. student in the Civil and Environmental Engineering department at UC Irvine, is interested in understanding how ash from wildfires and prescribed burns can be used as a treatment for per- and polyfluorinated substances. PFAS are a group of “forever chemicals” that can be found in heat-resistant materials – including fire extinguisher foam – and are extremely difficult to eliminate.
Before Nguyen could collect her ash samples, Carmignani needed to cautiously set the dried shrubs on fire, providing a realistic situation for data collection purposes.
“We're trying to figure out if the ashes from these fires can be used as activated carbon, which could be used as a treatment for PFAS,” said Nguyen. “We want to see if this treatment can basically absorb PFAS and prevent it from traveling into soil and groundwater.”
While Nguyen is concerned about the impact that wildfires have on the land, Soroush Neyestani, a postdoctoral scholar in the Environmental Sciences department at UC Riverside, is interested in its impact on the air quality.
During a fire, it's difficult to determine how much emissions are a result of flames versus smoldering, the process of burning slowly with smoke but no flames, and current air quality models do not provide accurate guidance on this matter. Using an air quality sensor, Neyestani wants to quantify the difference in emission levels during the two phases.
“There are assumptions that 50% of emissions come from smoldering, but every fire is different. Our main objective is to improve the accuracy of air-quality forecasting,” Neyestani said, noting his concern that these assumptions might not be realistic.
Although the field day was created with the students in mind, Carmignani used the opportunity to polish his own research efforts. Since fall 2022, he has been investigating the flammability of low-water use landscape plants based on various irrigation applications.
“Every time we burn, I feel like we get better. We get better data, and we conduct better analysis, and that's really important for us so that we can figure out how we can apply our research and measure its outcome,” said Carmignani.
In addition to welcoming more collaborations with UC campuses and other organizations, Carmignani is hopeful that these combined research efforts will spark an interest in wildfire awareness everywhere.
