Wheeler-Dykes returns to roots with tree crops, weeds
“I was born and raised on a small prune and walnut farm in Gridley, in nearby Butte County, and am very excited to be putting down roots close to family,” said Wheeler-Dykes, who started in this role on June 1.
Covering olives, prunes, walnuts and almonds, with an emphasis on weed management research in those cropping systems, Wheeler-Dykes is spending her first months on the job getting to know the region's growers and broader agricultural community.
“I hope to really form great relationships with the clientele in my counties, providing a resource that they can trust and rely on,” she said. “I want to serve as an advocate for our region in developing research and finding answers for the unique systems we have here. My interests are alternative weed management in orchard systems and canopy management, but I look forward to hearing what other areas need to be addressed.”
After earning both a bachelor's in crop science and business management and a master's in entomology (with a focus on integrated pest management in tree crops) from UC Davis, Wheeler-Dykes has conducted extensive agricultural research.
“I'm excited to bring those experiences to the Sac Valley as the newest advisor,” she said, encouraging growers and producers in the region to contact her with the challenges they are facing.
Based at the UCCE Glenn County office in Orland, Wheeler-Dykes can be reached at bawheeler@ucanr.edu and (530) 884-9313.

Johnson joins UC ANR as urban ag tech advisor
Johnson provides unbiased, research-driven information to people working in urban agriculture, with a focus on controlled environments such as greenhouses. His clientele is interested in adopting technologies that can improve plant production, ranging from nurseries and commercial growers to community members managing local gardens.
In his newly created role, Johnson's efforts will influence the scope of work for urban agricultural technology advisors to come. One of the challenges that he anticipates is “focusing knowledge” or choosing a specific problem to prioritize.
“I'm really interested in irrigation, soil and plant culture. There's a lot to consider and there's a lot that can be done,” said Johnson.
Before he was hired as an advisor, Johnson worked as a staff research associate for five years at the South Coast Research and Extension Center in Irvine under Darren Haver, director of UC ANR's Research and Extension Center system.
“I learned a lot while I was an SRA, but there was only so much that I could do. I wanted more freedom to explore as a researcher, so I decided I wanted to become an advisor,” Johnson said, adding that his career goal inspired him to return to school.
Johnson earned a master's degree in horticulture and agronomy from UC Davis, as well as a bachelor's degree in biology from Cal Poly San Luis Obispo.
One of the exciting aspects of the job, according to Johnson, is the ability to get creative and explore new territory. “I have some fun research interests, like how to grow wasabi or maximize saffron production using hydroponics,” Johnson explained.
“I'm interested in the kind of things that might be culturally important or significant to certain communities, and how they can be made more affordable and accessible,” he added.
Johnson is based out of the South Coast Research and Extension Center and can be reached at gejohnson@ucanr.edu.

Reyes joins UCCE as orchard systems advisor 
Clarissa Reyes joined UC Cooperative Extension on March 1 as an orchard systems advisor. Her role focuses on walnut, cling peach and kiwifruit production in Sutter, Yuba, Butte and Placer counties. Reyes serves as a point of contact for orchard owners when they need support diagnosing problems and solving them.
Reyes is excited about developing climate-adapted management practices and working with the recently expanded team of orchard advisors serving the northern Sacramento Valley, but she also anticipates encountering some challenges.
“Some of the challenges I expect to face are low crop prices despite increasing costs to farmers, including labor and inputs; water scarcity; and more frequent and higher temperature heat waves affecting fruit development and quality,” explained Reyes.
Reyes earned a master's degree in horticulture and agronomy from UC Davis. She also earned a bachelor's degree in biology from UC San Diego.
When describing her journey into agriculture, Reyes said that she “likes the way food makes it easy to connect with people.” She also said that after realizing a career in biotech was “not a good fit,” she let her love for gardening alter her career path.
“I'm really into food systems and food is an important part of culture,” said Reyes. “So, it was the overlap of research and food. Even though the science part can go over someone's head, everyone understands food.”
Before joining Cooperative Extension, she worked as a junior specialist studying plant-water relations at UC Davis. While her research was focused on grapevines, she started working with walnut trees, which exposed her to opportunities in orchard systems. Afterwards, she became a staff research associate in orchards systems in Butte, Glenn and Tehama Counties.

Harris honored by University of Wisconsin-Madison institute
In her lectureship presentation, “Nuts! How a foodborne outbreak serendipitously shaped a career,” Harris described how in 2001, an outbreak of salmonellosis was linked, for the first time, to consumption of raw California almonds.
The traceback investigation identified the outbreak strain in the almonds at retail and all along the supply chain back to the orchard. As the outbreak investigation was winding down, her laboratory was beginning what became a 20+ year journey investigating Salmonella and almonds from production agriculture through final consumption. Studies sought to uncover potential routes of contamination and long-term environmental persistence of Salmonella during production, harvest and postharvest handling. Laboratory studies focused on methods to inoculate and recover microorganisms from almonds, survival of pathogens on almonds during storage, and evaluation of the thermal resistance of pathogens and candidate surrogates.
These data, along with information on the prevalence and levels of Salmonella in almonds, enabled the development of quantitative microbial risk assessments, the establishment of appropriate target reductions for lethality process controls, and validation of several key commercial practices such as blanching and oil roasting. More recent studies have explored the risks associated with soaking almonds and a range of dairy analogs made from them.
Since worldwide nut production has expanded rapidly over the past 20 years with a corresponding increase in consumption, Harris and her laboratory's work with the behavior, movement, prevalence, and especially control of foodborne pathogens, from the field to consumer handling, from almonds to pistachios and walnuts, has been and will continue to be a foundation for food-safety tree nut and produce research. – Zann Gates
Ferguson named ASHS Fellow
The recognition is “more than well-deserved and should have happened YEARS ago!” wrote ASHS Executive Director Michael Neff. ASHS fellows are elected “in recognition of outstanding contributions to the science, profession, or industry of horticulture,” he added.
“It is gratifying to be honored by one's peers,” said Ferguson.
Under Ferguson's guidance, the ASHS Leadership Academy began two years ago by offering online seminars to participants from all over the United States. “We're training them to be leaders in our professional society, and also to be advocates for the society,” Ferguson said. The program pulls together the ASHS foundations of research, teaching and practice, which was capped earlier this year by a trip to Washington, D.C., to advocate in Congress for the 2023 Farm Bill Reauthorization.
The current second class of the Leadership Academy will graduate and the third class will be inducted at the ASHS annual meeting, July 31 to Aug. 4, in Orlando, Florida.
Leadership training is important to Ferguson because she didn't get it early in her own career, she said. She wants to see the generation of new leaders coming up – as well as ASHS as a whole – to benefit from good preparation in this area, she added.
Ferguson has served as the society's president and president-elect during the challenging days of the COVID-19 pandemic, and has received other honors. – Trina Kleist
Kearns wins book award 
Faith Kearns' book “Getting to the Heart of Science Communication: A Guide to Effective Engagement” was selected as a 2023 Nautilus Book Awards Gold Winner in the category of Relationships & Communication (large press).
For scientists to communicate effectively about science, they must not only be experts in their fields of study, they must navigate the thoughts, feelings and opinions of the people they engage with and with each other.
Kearns, an academic coordinator for the California Institute for Water Resources at University of California Agriculture and Natural Resources, has written about what she has learned in 25 years of practice in Getting to the Heart of Science Communication: A Guide to Effective Engagement from Island Press. The book includes on-the-ground experiences of many science communicators, including those working in Cooperative Extension.
Dahlquist-Willard appointed to state Ag Land Equity Task Force
She is among the 12 inaugural members appointed by the California Strategic Growth Council to the task force, which will develop policy recommendations to equitably increase access to agricultural land for food production and traditional tribal agricultural uses. Established by the Legislature last year, the task force will meet every quarter over three years and submit a full report of policy recommendations to the State Legislature and Governor by January 1, 2026.
Historically, women and people of color in California have been blocked from stable access to land and other resources necessary for successful farming, a legacy that persists today. A recent study by the U.S. Department of Agriculture shows only 37% of all farmers in the California are female and only 9% are Black, Indigenous and people of color (BIPOC). In 2020, the California Department of Food and Agriculture found that such farmers and ranchers often lack stable access to land, which negatively affects the long-term sustainability of their businesses. Equitably increasing stable access to agricultural land in California will promote farmers' economic resilience, a robust food system in the state, and healthy natural and working lands.
The task force will have 13 regionally diverse members, including native and tribal liaisons, a land trust representative, individuals with expertise in issues affecting socially disadvantaged farmers or ranchers, an individual with expertise in agricultural land acquisition and finance, a State Board of Food and Agriculture member, a farmworker representative, a beginning farmer, the California Department of Food and Agriculture Farm Equity Advisor, and an individual from the new California Department of Food and Agriculture BIPOC Farmer Advisory Committee.
Dahlquist-Willard will contribute her expertise in issues affecting socially disadvantaged farmers or ranchers.

Californians have been dealing with wildfires, the pandemic, power shutdowns, excessive heat and drought, sometimes all at the same time. In every county, UC Cooperative Extension is there to assist community members.
To better serve their clientele, nearly three-quarters of UC Cooperative Extension employees say they need professional development related to disaster response, according to a new study led by Vikram Koundinya, UC Cooperative Extension evaluation specialist in the UC Davis Department of Human Ecology.
Koundinya and coauthors Cristina Chiarella, UC Davis doctoral graduate student researcher; Susan Kocher, UC Cooperative Extension advisor for the Central Sierra; and Faith Kearns, California Institute for Water Resources academic coordinator, surveyed UC ANR personnel to identify existing disaster management programs and future needs. Their research was published in the October 2020 edition of Journal of Extension.
“It's becoming so common that our folks are being put in the role of responding to disasters, while not having much training or background to do so,” Kocher said.
“And, it's really cross-disciplinary,” she added. “Right now, our nutrition folks are doing so much with assisting their communities with food access during COVID. Others, like Faith Kearns, have been working hard to address drought and help clientele weather drought impacts. There are the individual events like the LNU Lightning Complex fires [wildfires caused by lightning strikes in Lake, Napa, Sonoma, Solano and Yolo counties that burned from Aug. 17 to Oct. 2, 2020], but really, so many of us are currently doing disaster work across our disciplines and that role will only continue to expand with climate change-induced disasters. Once you frame it as ‘disaster work' you can start to see how our system needs to be much more prepared and to learn from and collaborate with each other and with disaster organizations.”
The survey showed that about one-third of the 224 respondents had been involved in preparing for, responding to, or helping communities recover from disasters. Respondents also noted a variety of needs related to disaster preparedness, response and recovery systems, procedures, materials and equipment, and educational materials.
“UC ANR personnel reported a need for professional development related to understanding how we fit into broader disaster response systems (73%) in California, what Extension resources are available for disaster response (63%), how the landscape of disaster risks in California communities is changing (62%), how communities can mitigate or manage disaster risks (62%), how to develop pre-established networks within the organization for responding to disasters (52%) and coordination with local and state entities (48%),” Koundinya said.
The authors note in the journal article, “Even though UCCE has been playing a critical role in disaster response for decades, because of the size and geographic spread of the UCCE system, disaster management approaches and materials have tended to develop piecemeal on a program-by-program and often county-by-county and disaster-by-disaster basis.”
The article, “Disasters Happen: Identifying disaster management needs of Cooperative Extension System personnel” can be viewed at https://joe.org/joe/2020october/a2.php.
“We recommend that the findings be used for designing professional development on the topics and needs identified by the respondents,” said Koundinya.
In her blog ANR Adventures, AVP Wendy Powers, wrote about the report, “The tables identifying needs are of particular interest to me and perhaps something the Learning and Development team might think about for future trainings.”
