Green Hall of Famer Oki retires after 29-year UC career

UCCE specialist's research prevents water pollution, reduces water use

When interviewed to become a University of California Cooperative Extension specialist in environmental horticulture, Lorence “Loren” Oki was asked what kind of research he wanted to conduct.

In response, he showed the hiring committee a photo of a residential gutter. “Water is a big concern, and I found very little research on runoff from homes,” said Oki, explaining that studying residential runoff is what “started his career” with UC Agriculture and Natural Resources back in 2002.

Although he remains active supporting growers and advising industry leaders, Oki retired from UC ANR in July 2023. Before joining ANR, Oki worked as a researcher for UC Davis' Department of Environmental Horticulture studying greenhouse irrigation in 1994, bringing his total time with the University of California to 29 years.

Oki, professor emeritus of Cooperative Extension at UC Davis, led many research projects that advanced the green industry which includes landscapes, nurseries and floriculture.

“Loren is the epitome of a specialist,” said Darren Haver, UC ANR's Research and Extension Center system director, who has worked with Oki for more than 20 years on projects that have  significantly improved urban water quality and water conservation efforts across California.

Research influences pesticide management

With a $3 million grant funding a statewide study, Oki and Haver set out to characterize runoff from residential sources over a five-year period. They determined the volume of irrigation runoff from residential land use, as well as the pollutants in the runoff.

Oki and Haver, co-principal investigators, along with researchers from UC Davis and UC Riverside, discovered that the degradation products of the insecticide fipronil – commonly found in runoff water – were more toxic than its parent compound. The study led to an investigation of human pathogens and pathogen indicators in residential runoff, the first of its kind.

Another contribution was the early detection of a new pesticide used for ant control, enabling strategies to be put in place to prevent it from reaching local streams and creeks. Oki and Haver's work also persuaded the California Department of Pesticide Regulation to change pesticide labels to minimize the chances of pesticides moving off target during irrigation and rain events.

These changes included preventing pesticide application before predicted rain and preventing irrigation after applications, keeping pesticides from impervious surfaces, and restricting applications on lawns and landscape beds within two feet of impervious surfaces and others.

Plant trials expand beyond California

Oki was also the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials, the California component of that project. The UCPLIT trials originated in 2004 at UC Davis as a research project by Karrie Reid, retired UCCE environmental horticulture advisor for San Joaquin County, while she was pursuing her master's degree. In 2017, the irrigation trials were duplicated at the South Coast Research and Extension Center.

These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water. Throughout the trial, Oki identified many landscape plants, including rose cultivars, that remain aesthetically pleasing with little water.

Today, the trials have expanded beyond California as the Climate-Ready Landscape Plants Project at Oregon State University, University of Washington, University of Arizona and Utah State University.

Growing up in the nursery industry

In 2017, Oki obtained tenure, allowing him to expand his professional responsibilities to include production horticulture, specifically greenhouses and nurseries, an industry he was extremely familiar with. “I come from a nursery family,” Oki explained. “My grandfather started Oki Nursery in the early 1900s.”

During World War II, Oki's family was incarcerated in the Poston Relocation Center in Arizona and lost their homes and property. When they were released, they returned to the nursery industry to rebuild their lives. “After World War II, my father and uncle got more involved with my grandfather's work,” he said.

The Oki family played an instrumental role in technological development for nurseries in general. Oki Nursery, which was located in Sacramento, worked closely with IBM and was the first to use a computerized system in the industry.

Oki developed computerized scheduling for the bedding plants, poinsettias, chrysanthemums, bulbs and other crops.  He developed a method to calculate the cost of any crop grown by the nursery at any point in the crop cycle and computerized greenhouse environmental and irrigation controls. This may not sound impressive now, but that was in the 1980s.

“My father was known for being progressive and he also knew everyone at UC Davis,” said Oki. “He wanted to work with anyone who had an interest in doing something good for nurseries.”

Inducted into Green Industry Hall of Fame

In the 1950s, Oki Nursery partnered with researchers from UC Davis' agricultural engineering program and developed the overhead sprinklers commonly used in nurseries today. Until the 1980s, Oki Nursery was the largest nursery in Northern California. Before it shut down in 1993, Oki worked in the family business as a greenhouse manager when runoff became a growing concern.

“I remember getting served with a notice by the Regional Water Quality Control Board stating that we needed to prevent runoff because it was polluted with nitrate fertilizer, which was common in the nursery industry,” Oki said.

One of those efforts focused on using controlled-release fertilizer instead of applying fertilizer via irrigation as a liquid feed. “What we learned is that if we converted nurseries to controlled-release fertilizer, we could reduce the nitrate runoff,” he said. While a member of the Oki Lab, Bruno Pitton earned his Ph.D. studying nursery hydrology and the fate of nitrogen fertilizers in container crop production adding to the information on runoff and nitrate management. Pitton is now the environmental horticulture advisor for Placer and Nevada counties. 

In 2023, Oki was inducted into the Green Industry Hall of Fame, which recognizes individuals with a minimum of 20 years in the landscape, nursery or floriculture industry and who have made significant contributions to the field.

Having grown up in the industry, Oki said that his father taught him to never be afraid to try new things. “If you think you have an idea that might work, do the best you can to make it work. If it doesn't work out, then it doesn't work out. And that's OK,” he said. 

Revitalizing space for greater impact

This mentality encouraged Oki whenever tackling new tasks, like rebranding the California Ornamental Research Federation, a space for education and collaboration, as UC Nursery and Floriculture Alliance.

In 2009, Oki and David Fujino, executive director of the California Center for Urban Horticulture, became co-directors of CORF, which catered to the cut flower industry. At that time, Oki and Fujino realized that nurseries generated much greater revenue in the state than cut flowers.

“It was a strategic decision to change CORF to UCNFA, which included floriculture and nurseries in the name,” Fujino said. Combined, nurseries and floriculture have consistently placed in the top five agricultural commodities in the state.

When reflecting on their partnership, Fujino said that working with Oki was a “natural fit.” “I couldn't have asked for a better partner, a better colleague and, ultimately, a better friend to have my back and work side by side,” he added.

Since UCNFA's launch, the two have worked to maintain the group's impact by hosting “Ask your Advisor” webinars to connect advisors to growers, as well as co-hosting large-scale events such as the annual conference for the International Plant Propagators' Society — an organization focused on greenhouse and nursery production education — for the Western Region, which Oki's father helped establish in the 1960s.

Encouraging a return to education

Gerry Spinelli, UC Cooperative Extension production horticulture advisor for San Diego County and member of UCNFA's administrative committee, described those who have learned from Oki as his sons and daughters. “When I meet someone that's learned from Loren or worked with him, that person instantly becomes my friend. That's the kind of effect Loren has on us,” Spinelli said.

Grant Johnson, UC Cooperative Extension urban agricultural technology advisor for Los Angeles and Orange counties, credits Oki for his master's degree in horticulture from UC Davis.

“Loren gave me a lot of direction as far as career choices and research interests. He instilled in me a dedication to life-long learning, just like he continues to do,” said Johnson. Before Oki became his professor, Johnson worked with Oki as a staff research associate at the South Coast Research and Extension Center in Irvine.

Another influential person in Oki's life is John Kabashima, emeritus environmental horticulture advisor for UCCE Orange and Los Angeles counties and fellow Green Hall of Fame inductee. Like Oki, Kabashima grew up in the nursery industry.

Oki, who earned a bachelor's degree in ornamental horticulture from Cal Poly San Luis Obispo and a master's degree in plant science from UC Riverside, decided to pursue a Ph.D. in ecology at UC Davis with Kabashima's encouragement.

While Oki was still working in his family's business, Kabashima said that Oki relied on UC ANR researchers for scientific information and felt like Oki wanted to be one of them. “I told him that he's a good nursery guy, but he's a better scientist,” said Kabashima. “His heart is in science.”

The two began working together as soon as Oki became a graduate student and have been colleagues and friends for nearly 40 years. “My favorite response from Loren whenever people ask him a question is, ‘It depends,'” Kabashima said. “It always leads to people opening up and giving more context. That's what Loren does, he gets you to think.” 

Norma De la Vega retires as broadcast communications specialist after 13 years

After 13 years of telling the UC ANR story through written articles and video production, Norma De la Vega retired on June 29. De la Vega joined UC ANR's News and Information Outreach in Spanish team in 2009 as a senior writer.

NOS fulfilled UC ANR's vision of developing educational and informational programs in Spanish to serve the Latino community. For more than 40 years, NOS has been producing information formatted for radio, television, and online audiences, and De la Vega has played an instrumental role in helping NOS expand its reach and diversify its creative approach to storytelling. 

When she started, most of her writing focused on nutrition, highlighting groups like the Expanded Food and Nutrition Education Program and the Nutrition Policy Institute. “Norma's contributions were spot on,” said NOS Program Manager Ricardo Vela. “Her impact has been bringing the importance of nutrition into the stories that we bring to the community.”

De la Vega earned a bachelor's degree in science communications from Universidad Nacional Autónoma de México in her hometown of Mexico City. “Learning how to produce videos when I went to school was very different than now,” said De la Vega. “We didn't have the kind of cameras we do today.”

Following college, De la Vega worked as a television reporter in Tijuana before moving to San Diego County where she started focusing on writing. Prior to UC ANR, De La Vega worked as a writer for the Enlace Union-Tribune's Spanish newspaper in San Diego for nearly a decade.

Before it became NOS' primary medium for storytelling, De la Vega helped lead the team's video production effort despite her limited experience. “We weren't experts, but we realized the importance of video production to get our information out. It was a team effort,” she said.  

In 2010, De la Vega wrote a story and produced a video on the importance of planning for old age. In many cases, adult children had to manage their parent's care without guidance, and most caregivers of the elderly spoke Spanish as their first language and needed more resources to do a better job.

De la Vega's story relied on research conducted by Patti Wooten Swanson, UCCE nutrition, family and consumer science advisor in San Diego. Not only was Swanson honored at the 2013 Galaxy Awards for her contribution to the story, but De la Vega, a member of the NOS team at the time, won first place at the Western Region Television/Video Communications Award Ceremony despite the lack of a Spanish language category.

In 2016, De la Vega produced a video of the first bilingual 4-H club, the result of a partnership with the Community Settlement Association in Riverside County. “A lot of good things were happening at that time and are happening now because ANR is evolving with more bilingual experts on different topics,” De la Vega said.

Although she started as a senior writer, De La Vega evolved and became a broadcast communications specialist. Her success in the role allowed her to become well-connected to other communicators and community leaders. “Norma always had a contact we needed for a story that we were working on,” said Miguel Sanchez, another broadcast communications specialist on the NOS team.

Lisa Rawleigh, NOS administrative assistant, established a personal and professional relationship with De la Vega. “Norma ensured that our Spanish articles were written properly and that we did not miss any accents or typos. I can always count on her to proofread my posts on social media,” said Rawleigh.

De la Vega said that she feels “enormously satisfied” to have worked with a team of fellow pioneers. “Although we were not experts, we learned so much every day and together,” De la Vega said. “Today, there are several experts in the production of community videos, and we helped enrich the graphic archive for UC ANR's community programs. I think our contribution was to lead the way in that direction.”

Looking ahead, De la Vega will be spending her retirement traveling and exploring other countries and cultures. Since she was a girl, De la Vega enjoyed swimming and can't wait to do more of it. “I love to swim because being in the water always makes me feel young,” she said.

Finally, De la Vega will enjoy quality time with her grandchildren, teaching them Spanish and volunteering at the Spanish immersion school they attend.

UCCE advisor John Borba retires after 30-year career helping youth in Kern County

John Borba, UC Cooperative Extension Kern County's 4-H youth development advisor, retired on July 1. For over 20 years, Borba has been key to the success of the 4-H program in Kern County, which affords young people an opportunity to test and strengthen their leadership skills while finding and building community.

Borba began working with UC Agriculture and Natural Resources in 1992 as the 4-H program representative for Tulare County. In 1999 he relocated to Oregon to work as an advisor for Oregon State University's Extension team before returning to California in Kern County in 2000.

For 30 years, Borba has focused on improving the lives of young people.

“I appreciated many things about John,” said Marianne Bird, 4-H youth development advisor for Sacramento County. “He was never the ‘sage on the stage,' but rather a thoughtful, competent partner who led from behind. And I loved to watch him teach – asking questions, engaging his audience, enthusiastic about his topic. He was an excellent teacher.”

Bird and Borba worked closely together, supporting and developing statewide 4-H camp programs for 15 years.

“He helped lead an amazing team of 4-H staff, volunteers, youth and academics in some of the most rewarding work of my career,” Bird said.

Together, Bird and Borba prioritized program improvement by presenting research findings at national and international camp conferences, conducting eight statewide conferences, developing camp safety and risk management resources, and authoring two books.

Among the 4-H activities offered in Kern County, Borba oversaw Operation Military Kids for children whose parents were deployed by the National Guard and the Reserves, connecting them with resources, social enrichment, recreational activities and educational opportunities.

To attract more Latino youth, families and volunteers into 4-H, Borba and his 4-H colleagues developed culturally relevant programs. As a result, the number of Latino youth participating in the 4-H program increased more than 250% in three years. The National Association of Extension 4-H Youth Development Professionals recognized the achievement with its Diversity & Inclusion: Expanding the 4-H Audience Award in 2021.

 

“Of the many programs, research projects, and activities that John led, it was his dedication to the Shooting Sports Program that had the most impact on and created significant impact for the youth and families who participated,” said Russell Hill, associate 4-H youth development advisor for Madera and Mariposa counties.

Borba's support resulted in the program – which promotes safety sportsmanship and ethical behavior – serving more than 4,500 youth annually with at least 16 hours of instruction to the more than 1,000 volunteers throughout his tenure. 

“John really took the Shooting Sports program to a level of coordination, improved training and volunteer development, and tracking of data,” Hill said.

While his work focused on youth, Borba's leadership and positive impact were felt among his colleagues as well. Borba, who earned an M.S. in human resources from Chapman University, contributed greatly to the workplace environment and culture.

“I am grateful for being able to work with and for John Borba as the director and advisor in this office for 10 years,” said Carol Heaton, Kern County 4-H office support technician. “It is without question that he treats everyone the same way: direct, considerate, honorable, with understanding and compassion. All this with a keen sense of humor. He is someone I look up to.”

Sue McKinney, 4-H program representative, agreed and added that Borba is the best supervisor she has ever had. 

“He was always quick to share his knowledge,” McKinney said. “In everything he did you could see his deep dedication to the 4-H program. He will be greatly missed by everyone in this office.”

Southwest 4-H Leader Amy Andrews notes that 4-H youth and leaders in Kern County will surely miss Borba's presence too.

“John Borba is a kind, helpful and caring person towards each and every person, whether they are in 4-H or not,” Andrews said.

In retirement, Borba, who has received the prestigious emeritus status from UC ANR, will continue to serve young people by developing a 4-H Avian Embryology Program. It is expected to launch in 2023.

“The goal of this program is to serve as an outreach tool for the Kern County 4-H program and the University of California. It has the potential to reach thousands of youth who would normally not be able to participate in a 4-H club,” he said, explaining that many of the participants are from populations underserved by the traditional 4-H club model.

Borba is hopeful that this program will contribute to enhanced classroom learning experiences and excite young people about animal science and food production processes. He also believes that it will contribute to improved behavior and attendance in school.

 

 

 

UCCE advisor Lynn Wunderlich to retire after 22 years as farm advisor

Serving Amador, Calaveras, El Dorado and Tuolumne counties, UC Cooperative Extension advisor Lynn Wunderlich was formally assigned to focus on viticulture and integrated pest management in the region. But her innate curiosity – as well as her dedication to meeting the wide-ranging needs of local communities – led her to develop expertise in a remarkable array of topics.

“That was both the challenge and the opportunity of being a foothill farm advisor – lots of small farms, lots of diverse agriculture, so I got to do some cool things,” said Wunderlich, who is set to retire on July 1. “To serve the needs of the clientele up here was very gratifying and interesting.”

Wunderlich earned her bachelor's degree in bacteriology and plant pathology from University of Wisconsin-Madison and her master's in plant protection and pest management from UC Davis. After several years as a UCCE staff research associate in Ventura and Monterey counties, Wunderlich began as a UCCE farm advisor in 2000 for El Dorado and Amador counties.

Although initially tasked with supporting tree fruit and specialty crop growers in topics such as researching alternative methods for managing codling moths, Wunderlich soon found herself studying organizational dynamics and bylaws to help the Placerville Fruit Growers Association cooperative transition to become a Limited Liability Company.

“It was really different than anything I'd been trained in before,” Wunderlich said.

That early experience set the tone for the rest of her career, as she continued to seek out – and share – knowledge across the expansive breadth of her work. In 2007, Wunderlich took on the viticulture role in Amador and El Dorado counties, where grape growers sought counsel on controlling a newly discovered pest.

“Every farm advisor has some quintessential moments of their career, and Gill's mealybug was one of mine,” Wunderlich recalled. “It's really unique; it's not found in very many places in California and it had never been described as a pest on wine grapes.”

In addition to developing effective management tactics for Gill's mealybug, Wunderlich worked with growers and the late Doug Gubler, UCCE specialist emeritus, to set up seven powdery mildew stations and rain gauges across the foothills. The stations filled a great need in the region by providing accessible, applicable pest and disease forecasting and precipitation data.

Crediting her colleagues' tutelage, Wunderlich also deepened her understanding of the diverse soils in the foothills and the latest research on evapotranspiration on wine grapes – all in the name of delivering the most current and useful information to growers.

“Lynn provided our growers excellent guidance, knowledge, and networking with a passionate thirst for continued discovery, and she always brought her wonderful smile and signature friendly demeanor to our farms and meetings,” said Chuck Mansfield, general manager of Goldbud Farms. “Farming often goes hand-in-hand with setbacks, but Lynn's continued pursuit of knowledge offered our growers motivation, hope, new strategies, and ultimately success against many of the recent challenges presented by Mother Nature.”

When Christmas tree growers in the foothills found their white firs decimated by a phytophthora pathogen, Wunderlich helped them switch to Nordmann and Turkish firs, which were naturally resistant. She became one of only a few experts in the UC system on these conifers, and, in one of her last accomplishments as farm advisor, organized the International Christmas Tree Research and Extension Conference in California earlier this month.

Another late-career highlight for Wunderlich was developing training materials on the proper calibration and use of air blast sprayers. Alongside Franz Niederholzer, UCCE farm advisor for Sutter, Yuba and Colusa counties, and UC IPM colleagues Lisa Blecker, Petr Kosina and Cheryl Reynolds, Wunderlich developed, delivered and evaluated a curriculum that included both in-person classes and online components. Their efforts were recognized with an IPM Achievement Award from the California Department of Pesticide Regulation, and the online course continues to be used today.

“It's nice to be able to leave something like that behind; its principles are still valid, no matter what type of sprayer you're using,” said Wunderlich, citing it as one of her enduring legacies.

In retirement, Wunderlich plans to continue her lifelong learning and also spend more time with friends and family – especially on camping trips on the east side of the Sierra.

And, as for growers such as Chuck Mansfield, they hope Wunderlich will stay connected.

“While we are all very happy for Lynn, her presence will be sorely missed,” Mansfield said. “We hope Lynn remains a regular fixture and friend in our community.”

UC Cooperative Extension advisor John Karlik retires after a 38-year career in Kern County

John Karlik, UC Cooperative Extension advisor in Kern County for environmental horticulture and environmental science, will retire July 1. Karlik began his work in Kern County in 1984 with an emphasis on the commercial rose plant industry and local horticulture outreach.

Karlik's teaching activities included five levels of 12- to 15-week horticulture education classes offered in three locations in Kern County, usually two or three classes held each year. For the past 25 years, he has collaborated with Darrell Feil, co-owner of Abate-a-Weed in Bakersfield, to hold landscape management seminars that connect community members with experts on a wide range of topics.

“What I love about John is a couple of things: first, his knowledge base is amazing – he's a treasure of Kern County, for what he's done education-wise,” Feil said. “And second, he has a very active mind – and so many people benefit from that in our community.”

Karlik expanded his teaching to include 10 horticulture study tours to gardens and landscapes of Europe and Asia, and the photographs from those visits enhanced his outreach and contributed to his chapters on landscape design in the Arizona and UC Master Gardener Handbooks.

He earned his B.S. in soil science from the University of Minnesota and M.S. in horticulture from Michigan State University.

Taking advantage of UC Agriculture and Natural Resources' flexibility and sabbatical leave, he completed a doctorate at UCLA in Environmental Science and Engineering, and changed his research focus to air-quality-related projects. That led to a lecture series on atmospheric science and policy, including climate change, which Karlik offered annually for 15 years as a visiting professor at Central European University in Budapest, and resulting in a service award from that institution.

In recent years, he led four tours to study ecosystem response in the still-radioactive Exclusion Zone at Chernobyl, Ukraine, site of the world's worst nuclear accident.

In response to the COVID-19 pandemic, Karlik shifted from in-person classes and offered 75 hour-long Zoom presentations on horticulture, landscape design, climate change and environmental science topics, finding an audience in California and in other states.

Karlik also has held a variety of positions in ANR committees, including Academic Assembly Council and the Communications Advisory Board.

“I especially appreciate the many collegial relationships I have within UCCE, ANR, and on several campuses,” Karlik said. “Authorship on many publications reflects those relationships.”

In retirement, Karlik expects to offer assistance at the UCCE office in Kern County and as an editor for a forthcoming ANR book. He intends to pursue interests in instrumental music and the study of languages.

“We've been really blessed to have a guy like John around,” Feil said.
