Matthew Barnes

New Cooperative Extension director has worked extensively with Native American communities, youth groups

Growing up in Upper Lake, along the “North Shore” of Clear Lake, Matthew Barnes lived near several of the Lake County region's seven federally recognized tribes. Although he counted several Native Americans among his diverse circle of childhood friends, and was very familiar with those communities, Barnes was nonetheless quite nervous when he was appointed in 2009 as the inaugural executive director of the Boys & Girls Club of the Pomo Nation.

Barnes – a non-Native of European and Filipino descent – vividly remembers the tribal administrator paying him a visit on one of his first days on the job. “He said, ‘Hey, you have two ears and one mouth, so listen twice as much as you speak and you'll be fine,'” Barnes recalled. “And that's definitely stuck with me.”

That approach is continuing to guide Barnes in his new role as University of California Cooperative Extension director for Lake and Mendocino counties. He will guide and support research, outreach and education activities to meet the area's agriculture, natural resources, and youth and community development needs.

Since starting in May, Barnes has been getting a crash course from UCCE advisors and staff on viticulture research, pest management practices, 4-H camps, and a host of other projects and programs – while also meeting with local communities on the region's most pressing challenges.

“What I've been doing – and will continue to do – is just to listen and learn, and when I can add value to a conversation or project, then I'll do that,” Barnes said. “But leadership to me starts with the relationships we build – with our staff and with the community.”

Bringing a range of experiences in youth programs, social services

One area in which Barnes will certainly add value is developing youth and community programs. During his time with Boys & Girls Club of the Pomo Nation, it was one of only three Boys & Girls Clubs established on tribal land in California. In that role, Barnes faced the unique challenge of integrating the Boys & Girls Club curriculum into a community for which it was not originally designed.

By adapting the curriculum to include culturally relevant topics, Barnes transformed the program into a model that eventually aided in the creation of a Native American-focused branch, Boys & Girls Clubs of America Native Services.

“This initiative now serves as a national standard for Boys & Girls Clubs on tribal lands,” Barnes said.

He later became a director of California Tribal TANF (Temporary Assistance for Needy Families), a direct cash assistance and supportive services program for Native American families in 17 counties across the state.

During his decade of TANF work, Barnes launched career development programs, alcohol and other drug counseling programs, and cultural revitalization initiatives. Some of the programs are still running and serving communities to this day.

“The trick is making those programs something that participants can see the value in,” Barnes explained. “And to do that, you go into the communities and talk to people and listen to what they need – instead of you telling them what they need.”

Barnes' experience partnering with Native American communities is just one of the many strengths he will bring to UCCE and UC Agriculture and Natural Resources.

“We're very excited to have Matthew join the UC ANR family,” said Lynn Schmitt-McQuitty, UC ANR's director of County Cooperative Extension. “His personal knowledge of Lake and Mendocino counties and his previous work with Indigenous populations will be a tremendous asset to extending and elevating our work.”

Immediately prior to joining UC ANR, Barnes served as director of Lake County's Upward Bound program, which helps students from three local high schools experience and prepare for higher education.

“Overall, what drives me personally is the opportunity to make an impact on communities, on youth, and on people in general through program development and management,” Barnes said.

Inspiring young people as a mentor

Barnes' passion for youth development – and the impetus for his bachelor's degree in social work from Cal Poly Humboldt – can be traced to his AmeriCorps experience while he was attending Mendocino College. For two years, he worked as a tutor for young people, in Lake County and then in Sonoma County, and saw firsthand the difference educators and mentors can make in their lives.

“You could say I kind of caught the bug – just seeing the light bulbs go on when you're helping a youth of that age,” Barnes said.

From there, Barnes took a position directing teen programs for the Boys and Girls Club of Healdsburg, where he began to fully appreciate the importance of trusted adults simply “being there” for young people as a listening ear for whatever they want to talk about.

Among the many teens Barnes worked with, “Rodrigo” was a middle schooler who was pegged by his school and community as someone who could “slip through the cracks.” Rodrigo was the last to go home at the end of each day, and Barnes would chat with him – answering his questions about life or just talking about a new rap album.

“I realized I was ‘that person' for him – that person outside his house, outside his school,” Barnes said.

Even after Barnes left the Boys and Girls Club, Rodrigo – bound for university – invited him to his high school graduation. Barnes said it is tremendously gratifying to know he had a “small role” in shaping the path for Rodrigo – and countless others.

“Their success is still theirs; it's not necessarily because of me,” Barnes added. “My job is to do what I can in the moment to hopefully plant some seeds that may sprout in the future.”

Settled in Middletown, not far from his hometown, where he and his wife are raising two children, Barnes is now positioned to help nurture a flourishing Lake County and resilient Mendocino County.

“I feel like my past experiences, both in life and my career, have prepared me for this,” Barnes said.

John Harper gives sheep shearing pointers. Most of the sheep shearers currently working in California have graduated from his sheep shearing school, which started in 1993.

UCCE livestock advisor John Harper retires after 32 years

"If you know how to shear, you'll never be poor," Stephany Wilkes remembers John Harper, University of California Cooperative Extension livestock and natural resources advisor for Mendocino and Lake counties, telling her sheep shearing class in 2013.

“He was speaking to everyone, of course, but he really spoke to me: being poor (again) is one of my greatest fears and I've avoided it at all costs,” Wilkes said. Harper's words and a certificate from the course gave her the confidence to leave Silicon Valley for greener pastures.

“Eleven years later, with a successful business and published book about shearing to boot, I can confirm John does not lie to his students,” says the former software developer. “More than that, he is encouraging, calm, respectful, experienced, honest, funny and an excellent storyteller. If not for John, I would not have the life I live today.”

Today, Wilkes is a sheep shearer, knitter and author of “Raw Material: Working Wool In the West.”

Harper officially retired July 1, 2023, after 32 years in his UC Cooperative Extension advisor role, but returned to serve as interim director of UCCE for Mendocino and Lake counties until Matthew Barnes was hired on May 1.

For years, UCCE has offered the only five-day sheep shearing school in California, training 15 to 28 students annually, and Harper has been the force behind it.

“Most of the shearers now in the shearing business in California were trained by me and my fellow instructors,” said Harper, the state's Ed Sheeran of sheep shearing.

He first offered the sheep shearing school in 1993 at the Paul and Kathy Lewis ranch in Upper Lake, with subsequent schools at the Stanley Johnson ranch in Booneville. In the early days, Harper brought in instructors from New Zealand, before he and Mike McWilliams, a former member of the USA Sheep Shearing Team, began teaching. Later Harper moved the school to UC Hopland Research and Extension Center, where he has hosted the school for the past 27 years.

With grant funds from the National Sheep Industry Improvement Association, Harper bought shearing equipment and made seven portable shearing pens to offer shearing school at a private ranch in Clear Lake Oaks this year. 

“This program is nationally and internationally known and there is a waiting list of over 1,000 people who want to take it,” Harper said.  

Harper's baa-ackground in 4-H

Harper, who was active in 4-H as a boy, and his black-faced Hampshire ewe won the 1972 sheep showing competition at the San Diego Fair.

Growing up on his family's farm in Yucaipa, just east of San Bernardino, Harper's electrical engineer father gave him a choice between caring for the horses' hooves and shearing sheep. “I chose shearing since I wasn't very big and didn't like horses leaning on me,” he said. 

From age 9 to 19, he was active in the California 4-H Youth Development Program, achieving the Gold Star rank. “I was in 4-H with sheep, horses, veterinary medicine, tractor, electrical, welding and woodworking projects,” said Harper, who won the outstanding junior leader award. “I was a junior leader in sheep and won the state award for my sheep project. I showed registered Hampshire sheep, and my flock grew to 50 ewes before I was done.”

“Shearing sheep helped me pay for college,” said Harper, who earned a master's degree in range management at the University of Arizona and a bachelor's degree in animal science and agricultural economics at UC Davis.

After college, Harper worked as an assistant manager on the PolyPay breed development at Nicolas Sheep Farms in Sonoma before starting a career in Cooperative Extension in Arizona.

When Harper joined UC Agriculture and Natural Resources in 1991, the internet was in its infancy, but he recognized its potential for sharing information. He learned how to write code and created the university's first websites for livestock and natural resources. He also was an early adopter of blogging, Facebook, LinkedIn and Twitter to extend information, which earned him a silver award in 2011 from the Association of Natural Resources Extension Professionals.

Beyond shearing, Harper pioneered cutting-edge research

Although sheep are more photogenic on social media, Harper has been flooded with awards and accolades for his water quality research.

Informed by research from Harper, Lake County rancher Russ Rustici created the first rangeland water-quality ranch plan in the state. Rustici was so pleased that he donated research funding for the entire UC Rangeland Watershed Program team and later established two endowed chairs at UC Davis and one at UC Berkeley. The Rustici Endowment now provides research and education grants for rangeland and cattle efforts.

In 1995, Harper and his UCCE colleagues began teaching the Rangeland Water Quality Planning Short Course to help land managers develop water-quality management plans for their ranches to prevent water pollution. By 2015, they had taught more than 80 of these short courses, reaching more than 1,000 ranchers in 35 counties, representing over 2 million acres statewide. In one follow-up survey, 68% of the participants said they had implemented practices on their ranches to protect or improve water quality. 

In 2012, the Western Extension Directors Association presented Harper with its Award of Excellence for the Rangeland Watershed Program.

In 2022, the 12th District Agricultural Association Redwood Empire Fair named Harper the Mendocino County Agriculturalist of the Year. On the right, emeritus UCCE advisor Pete Passof cheers for his colleague.

Eating between the vines

For one livestock research project, he and UCCE colleagues trained sheep to graze the grass in vineyards and not eat the grapevines. “The results went viral internationally and really brought targeted grazing to the forefront,” Harper said. “It also raised sheep number by 2% in our two counties.”

In addition to advising ranchers and teaching sheep shearing, Harper has served in several leadership positions, rotating in every few years as UCCE director in Mendocino and Lake counties. From 2014 to 2017, he led UC ANR's Sustainable Natural Ecosystems Strategic Initiative, advocating for the hiring of experts in climate change, economics, small ruminants, forestry and fire.

“I'm especially proud that we were able to recruit a small ruminant extension veterinary specialist – a position that was unfilled for over seven years, despite California being the second-largest sheep-producing state in the nation,” Harper said. 

The certified rangeland manager and rangeland professional has long been a member of the Society for Range Management and the American Society for Animal Science. In 2008, he served as president of the California-Pacific Section of the Society for Range Management. Currently he is the secretary/treasurer for the Mendocino/Lake Wool Growers Association and is ad hoc director of the Mendocino/Lake County Cattlemen's Association. 

In 2015, the Society for Range Management gave him the Outstanding Achievement Award-Stewardship. In 2017, the California Wool Growers Association bestowed on him its Golden Fleece Award for Lifetime Achievement. In 2019, Harper was named Range Manager of the Year by the California-Pacific Section of the Society for Range Management for his contributions to the profession. In 2022, the 12th District Agricultural Association Redwood Empire Fair honored him with their Mendocino County Agriculturalist of the Year Award.

In retirement, Harper will have more time to play his banjo.

Harper also received UC Agriculture and Natural Resources' prestigious emeritus status. In retirement, he plans to play his banjo and continue offering the sheep shearing school with GaryVorderbuggen, who has been teaching with him for 18 years. Randy Helms, a former member of the USA Sheep Shearing Team, and Harper's former students Matt Gilbert, Lora Kinkade and Wilkes are among those who have re-ewe-nited with him as sheep shearing instructors.

“John taught the UCCE sheep shearing schools I attended in 2013-2015, and I was deeply honored to teach beside him in 2023 and 2024. It is one of the highlights of my life,” said Wilkes, now better known for working with wool than developing software.

“Like so many past students, I am forever in his debt,” she added. “We've got to keep this shearing school you started going, John. It is a gift. Thank you.”

To help more Californians address challenging issues, University of California Agriculture and Natural Resources has hired UC Cooperative Extension experts to work in communities stretching from Humboldt and Siskiyou counties in the north, and south to San Diego County. State funding has enabled UC ANR to expand its expertise.

Since 1914, UC Cooperative Extension's researchers have been working directly with community members to improve the lives and livelihoods of Californians.

The nine recently hired UC Cooperative Extension specialists and advisors bring expertise in forestry, pest management, water, plant disease, horticulture, toxicology, economics, rice farming and wildfire.

Gill joins UCCE as environmental horticulture advisor

Haramrit Gill joined UC Cooperative Extension on April 1 as an environmental horticulture advisor for Tulare, Kings, Fresno and Madera counties.

She will be identifying landscape plants that are heat-tolerant, disease-resistant and fire-resistant. Gill will be researching California native plants with sustainable attributes that include superior adaptation, biodiversity enhancement, water efficiency and soil health benefits.

A native of Punjab, India, Gill earned her undergraduate degree in agriculture followed by a master's degree in horticulture at Punjab Agricultural University, where her research focused on micropropagation and haploid production in muskmelons. She earned a Ph.D. from the Department of Horticultural Sciences at Texas A&M University.

Her early research investigated the impact of nitrogen on spinach root architecture. Her doctoral work concentrated on rose breeding and deciphering the genetic underpinnings of flower color transition traits, fragrance and dwarfing in roses, with a particular focus on the intriguing phenomenon of flower color transformation from yellow to dark pink as blooms matured. She also collaborated on projects aimed at enhancing heat tolerance and disease resistance in roses. 

Gill is based at the UCCE office in Tulare and can be reached at hamgill@ucanr.edu.

Jordan joins UCCE as forestry and natural resources advisor 

Christian Jordan

Christian Jordan joined UCCE on March 18 as a forestry and natural resources advisor for Shasta, Siskiyou and Trinity counties. He will work to advance forest resilience and sustainable management on private and public lands, with a focus on conifer forest resource management and sustainable natural resources. 

In 2020, Jordan completed a Master of Forestry at UC Berkeley, with an emphasis on forest resilience in the context of increasingly severe wildfires. Prior to joining UC ANR, he worked in the private sector in defensible space and home hardening, installing residential exterior sprinkler systems for ember defense.  

Jordan brings a diverse educational and work background to the position. In 2014, he earned a bachelor's degree in geography from UC Berkeley, writing a thesis on future climate and viticulture in Napa and Sonoma counties. Upon graduating, he worked in the wine industry before returning to natural resources.

Pastrana joins UCCE as plant pathology advisor 

Ana Pastrana

Ana Pastrana joined UCCE on Jan. 16 as a plant pathology advisor serving Imperial, Riverside and San Diego counties.

In her role, Pastrana will collaborate with pest control advisers and support growers with disease management. In addition to identifying high priority concerns, she will conduct research and develop educational content that addresses growers needs.

Before moving to Southern California, Pastrana worked as a research scientist on plant pathology at the University of Seville, Spain, and at Vineland Research and Innovation Center in Canada. Previously, she completed a postdoctoral assignment in the Department of Plant Pathology at UC Davis in the Thomas Gordon Lab, where she specialized in soilborne diseases affecting strawberries and blackberries. 

While attending the University of Seville, Pastrana earned master's and bachelor's degrees in biology. At Investigación y Formación Agraria, Pesquera, Alimentaria y de la Producción Ecológica, a government institution in Spain, she earned a Ph.D. and completed her dissertation on strawberry diseases. 

“At that time, Europe banned methyl bromide and other soil disinfectants. Strawberries rely on these disinfectants so plenty of soilborne diseases emerged,” Pastrana said. 

Originally from Seville, Spain, Pastrana said that her small hometown is surrounded by plum and citrus trees. Her mother, like many others, worked in the agricultural industry and Pastrana wondered how plant life works, inspiring her to study biology. 

As a Ph.D. student, Pastrana didn't know she would pursue plant pathology specifically because she was open to studying diseases in general whether it be humans, animals or plants.

“Plant pathologists are like doctors. Not everyone is happy to work with us because it usually means that there is some sickness involved,” said Pastrana. “But if growers work with pathologists from the beginning, we can focus on preventative care and helping to protect plants from getting sick.” 

Pastrana is based at the UCCE office in Holtville and can be reached at ampastranaleon@ucanr.edu.

Mokwunye named area IPM entomology advisor 

Idong Mokwunye

Idongesit Mokwunye joined UCCE on Jan. 3 as an area integrated pest management entomology advisor.

She will be studying insect pests of economic importance affecting tree fruit and nut crops, such as pistachio, almond, walnut, table grapes and stone fruit. Major pests include navel orangeworm, mealybug, carpophilus beetle, mites and scale insects.

Prior to joining UC ANR, Mokwunye worked as a nut crop entomologist at the Cocoa Research Institute of Nigeria for over 15 years and headed its Crop Protection Division.

“My journey into entomology as a career started when I was posted to the Cocoa Research Institute of Nigeria for the mandatory one-year National Youth Service Corp,” Mokwunye said.

“I was really fascinated at the diversity and economic importance of the insect species (both beneficial and pests) on agricultural crops and natural landscapes generally,” she said. “The hands-on lab experiments and field activities were exciting, engaging and inspiring. I was actively involved in setting up experiments, data collection, data entry and informal discussions on research projects. I was seeing the insect world in an entirely different perspective.” 

She already held a bachelor's degree in zoology from the University of Lagos, Nigeria.

“The then-head of the department observed my interest and encouraged me to get a master's degree,” said Mokwunye, who then earned a master's degree in entomology from the University of Ibadan, Nigeria. “During the course of the second degree, I got a job in the same institute and today the rest is history.”

Mokwunye holds a Ph.D. in entomology from the Federal University of Agriculture Abeokuta, Nigeria. Her research interests include integrated pest management, chemical ecology, extension entomology and economic entomology. She has worked on the population dynamics of the cashew stem girdler as it correlates with weather parameters, its damage potential, semiochemical interactions and chemical control of insect pests.

She has served as a resource person engaging stakeholders in outreach activities and facilitating training programs on good agricultural practices. In addition to publishing more than 25 research articles, she is a fellow of African Women in Agricultural Research and Development, Orange Knowledge Program of the Netherlands Government, and Scientific Exchanges Program of the USDA. 

“I am delighted to be here as a UC Cooperative Extension advisor and I hope to bring my expertise and experience in pest management to bear,” she said. “I plan to connect and engage meaningfully with my clientele in order to understand their needs, priorities and perspectives regarding pest management issues.”

Mokwunye is based at Kearney Research and Extension Center and can be reached at (559) 807-0257 and imokwunye@ucanr.edu. 

UCCE water advisor Garza hopes to foster ‘spirit of shared responsibility' 

Laura Garza

Laura Elisa Garza Díaz joined UC ANR on Jan. 3 as the UC Cooperative Extension water quality, quantity and climate change advisor for Lake and Mendocino counties, focusing on how intensified droughts, floods, wildfires and other climate impacts affect water supply and quality.

She aims to address Sustainable Groundwater Management Act requirements and enhance local water resilience in collaboration with farmers and natural resource managers, local government water agencies, water districts and other key stakeholders. 

In addition to guiding policymakers in creating comprehensive water-resiliency plans covering development, storage, alternative sources and conservation, Garza – who is fluent in Spanish – will share water research with a diverse range of communities.

“I aim to empower local stakeholders by providing them with the knowledge and tools needed to navigate the complex landscape of water quality, quantity and climate change,” she explained. “My goal is to foster a spirit of shared water responsibility, and ensure that water management practices consider the needs of all – for a more just and inclusive environment for everyone.”

Originally from Monterrey, Mexico (“the city of the mountains,” as she puts it), Garza earned her bachelor's degree from Tecnológico de Monterrey. After completing an Erasmus Mundus joint master's degree program in applied ecology, Garza worked as a specialist with the Water Center for Latin America and the Caribbean.

While pursuing her Ph.D. at UC Davis, she served as a scientific advisor for Pronatura Noroeste, an environmental protection organization, and started the Women in Science Interview Sessions at the Permanent Forum of Binational Waters, where she volunteered. It is an initiative to interview women who have worked or researched water topics in the Rio Grande/Rio Bravo Basin.

After obtaining her Ph.D. in hydrologic sciences from UC Davis, Garza worked as a project manager for the Washington Water Trust in Washington.

At every step of her journey, Garza has been motivated by a deep passion for safeguarding water resources and fostering resilient ecosystems and communities.

“I find inspiration in the intersection of science, community engagement and sustainable water management,” she said. “The opportunity to contribute to the well-being of local communities and the environment drives my commitment to addressing water challenges in a changing climate.”
