Pyle joins Sierra Foothill REC grassland research team

Lysandra Pyle joined ANR on Aug. 15, 2018, as an assistant project scientist. Working closely with project directors at UC Sierra Foothill Research and Extension Center and Eastern Oregon Agricultural Research Center (EOARC), Pyle is leading a multistate research project investigating biotic and abiotic drivers of native grass recruitment on degraded intermountain rangeland and identifying potential management actions that can be used to improve large-scale restoration efforts.

Most of her field work and project development is being done from EOARC, which is in close proximity to the Oregon and California intermountain field sites. 

Pyle completed a Ph.D. in rangeland and wildlife resources from University of Alberta, Canada, and a B.Sc. in biology from University of Regina, Canada.

Prior to joining ANR, Pyle worked on contracts specializing in biodiversity monitoring and rangeland ecology while finishing a Ph.D. in rangeland and wildlife resources at the University of Alberta, conferred in April 2018. From November 2017 to March 2018, Pyle was a vascular plant technician with Alberta Biodiversity Monitoring Institute (ABMI) at the Royal Alberta Museum. There, she identified vascular plants collected by ABMI technicians during the field season and contributed to publications.

Pyle also consulted as a plant community data analyst at Manitoba Forage and Grassland Association from January 2017 to March 2018, where she analyzed plant community data collected from the Aspen Parkland and Assiniboine Delta rangeland ecoregions, identified reference communities, and determined how they transition with disturbances such as grazing.

Her Ph.D. characterized the composition and diversity of grassland seed banks in two main studies: identified the diverse disturbance legacies and management histories of pastures on plant communities, seed banks, soils, and rangeland health, and examined legacy effects of pipelines on seed banks and biological soil crusts in native mixed grass prairie.

Pyle is based in Burns, Ore., and can be reached at (306) 551-1108 and lapyle@ucanr.edu. Follow her on Twitter at @GrasslandNerd.

Mahacek inducted into National 4-H Hall of Fame

Richard Mahacek, UC Cooperative Extension 4-H youth development advisor in Merced County from 1976 to 2012, was inducted into the National 4-H Hall of Fame on Oct. 19 for his lifetime achievements and contributions to 4-H.

Mahacek was one of 15 people inducted during the ceremony at the National 4-H Youth Conference Center in Chevy Chase, Md.

“We are proud to recognize the 2018 National 4-H Hall of Fame honorees for the passion, dedication, vision and leadership they have shown toward young people during their many years of service to 4-H,” said Jeannette Rea Keywood, National 4-H Hall of Fame Committee chair.

Mahacek joined a 4-H Club in Sonoma County when he was 10. During his 35-year 4-H career, Mahacek placed an emphasis on mechanical sciences and engineering projects. His work included development of curricula and activities in science processes, robotics, computers, GIS/GPS, bio-security and environmental issues, such as watersheds and wildlife habitats.

In 1988, Mahacek was a member of the team that developed the 4-H SERIES (Science Experiences and Resources for Informal Educational Settings) curriculum, which was funded by the National Science Foundation and Kellogg. SERIES was the first comprehensive pragmatic science education curriculum to join 4-H's traditional projects. In 2004, Mahacek served on the national leadership team for 4-H SET (Science, Engineering and Technology), a program that succeeded SERIES. Now known as STEM (Science, Engineering, Technology and Math), the project aims to enhance young people's interest in developing the knowledge and skills needed for the 21st century's technically oriented careers.

The crowning achievement of his career was the development of the 4-H Junk Drawer Robotics curriculum in 2011. The curriculum shows how to engage children in building robotic devices with rubber bands, Popsicle sticks, medicine dispensers and bamboo skewers – the kinds of things people already have around the house. The robotics program develops skills that go beyond science and engineering. The children learn communications, teamwork and critical thinking.

Junk drawer robotics is one part of a three-track robotics curriculum. The other tracks are virtual robotics, in which participants build virtual robots on computers, and robotics platforms, which employs commercial robot building kits for materials. The package of robotics programs was the No. 1 selling 4-H curriculum in the nation in 2011. Mahacek was also a driving force in the community in founding the UC Merced Engineering Service Learning Program Castle Science and Technology Center. This facility used a former US Air Force facility to provide hands-on science experiences to the youth of the county.

Mahacek received many honors for his contributions to 4-H and UC Cooperative Extension. In 1988, he received distinguished service awards from the state and national 4-H associations. The Merced County Farm City Ag Business Committee presented him its Agri-Education Award in 1992. Mahacek received the “Hands-On Heroes Award” at the Merced County Children's Summit.

Mahacek said the 4-H program has evolved during his tenure, but it has not changed its core objectives.

“We went from being a predominantly ag program to including many other topics. Our members used to live in just rural settings, but now they come from the suburbs and urban neighborhoods,” Mahacek said. “But we're still promoting the concept of working together and gaining confidence by learning practical skills.”

The National 4-H Hall of Fame honorees are nominated by their home states, National 4-H Council, the National Association of Extension 4-H Agents or 4-H National Headquarters/National Institute of Food and Agriculture based upon their exceptional leadership at the local, state, national and international levels.

Wilen recognized for contributions to nursery industry

Cheryl Wilen, area IPM advisor based in San Diego County, was presented the Research Award by the California Association of Nurseries and Garden Centers (CANGC) for her contributions to the nursery industry at the CANGC Convention in San Diego on Oct. 10, 2018. 

“This award acknowledges Dr. Wilen's many significant contributions over her career that have benefited the California nursery and landscape industry,” said Loren Oki, UCCE environmental horticulture specialist in the Department of Plant Sciences at UC Davis and co-director of UC's Nursery & Floriculture Alliance, who presented the award to Wilen.

Wilen specializes in Integrated Pest Management (IPM) for ornamental plant production and maintenance in nurseries, greenhouses, field production, floriculture, turf and landscape, which has resulted in the use of pesticides in a more prescriptive manner and the development of alternative strategies to more efficiently control pests of ornamental plants. Although her primary research focus is the management of weeds, snails and slugs, her other areas of research include the Asian citrus psyllid, disease management in floricultural crops, nematode management in tomatoes, invertebrate pest management in nurseries, vertebrate pest management, mitigating pesticide contamination in surface water runoff, and soil solarization. 

Wilen also recently received the UC ANR Distinguished Service Award for leadership. She has served ANR as the acting and interim director of the Statewide UC IPM Program, leader of the Endemic and Invasive Pest and Disease Strategic Initiative, member of Program Council, organizer of the Pest Management Coordination Conference, chair of several UC ANR search committees, and chair and member of the South Coast Research and Extension Center Research Advisory Committee. 

Her current and previous professional service includes chair of the Basic Science Section Western Society of Weed Science, chair of Teaching and Technology Transfer Section Weed Science Society of America, chair or co-chair of meetings of professional organizations including the California Weed Science Society, and has served or is currently serving as a member of various committees of the Weed Science Society of America, Southern California Chapter of the California Association of Pest Control Advisers, Steering Committee of the 2015 International IPM Symposium, and the CANGC Research Advisory Committee.

The CANGC Research Award recipient is selected by their peers and colleagues from industry and academic community.

Verdegaal inducted to San Joaquin County Agricultural Hall of Fame

Paul Verdegaal, who retired after serving more than 30 years as UC Cooperative Extension viticulture advisor in San Joaquin County, was inducted into the San Joaquin County Agricultural Hall of Fame on Oct. 18. Donald Rough, who was a UCCE pomology advisor, will be inducted posthumously.

“Verdegaal helped remove the stigma that Lodi could not grow premium wine grapes through exhaustive research, leadership and work with growers,” wrote Bob Highfill, marketing and communications manager for the Lodi Winegrape Commission, in the Stockton Record.

“During Verdegaal's tenure as farm advisor, the grape and wine industry in San Joaquin County flourished. Thirty years ago, there were 43,370 acres of grapes cultivated in San Joaquin County. In 2017, there were close to 100,000 acres. In 1986, Lodi was first recognized as an American Viticulture Area, but many, including the University, still felt that premium wine varietals could not be grown commercially in the Valley. Verdegaal worked hard to change that stigma.”

Kabashima honored with Urban Tree Legacy Award

John Kabashima, UCCE environmental horticulture advisor emeritus, received the Urban Tree Legacy Award by the California Urban Forests Council and the San Diego Regional Urban Forests Council at a ceremony in San Diego on Oct. 26.

Kabashima's varied research and extension programs have included the management of insects, diseases, and biological control of exotic and invasive pests. 

Kabashima, who retired in 2015 after 28 years of serving the nursery and landscape industry and homeowners in Orange and Los Angeles counties, continues to lead the battle against invasive shot hole borer pests that spread fusarium dieback, threatening trees in Southern California. On Oct. 3, Kabashima gave a presentation at an urban forest summit for public agencies, reviewing current pest concerns relating to trees for San Diego County and what the county needs to do to defend against future invasions.

He has provided testimony for the California Legislature to fund further research into these destructive pests. In January, Kabashima was instrumental in bringing together university scientists, federal and state government representatives, county agricultural commissioners and nonprofit organization leaders for a summit in the state capitol to coordinate their efforts to battle invasive pests.

Kabashima received his bachelor's degree in agricultural biology from Cal Poly Pomona, master's degree in pest management from UC Riverside, an MBA from Pepperdine University and a doctorate in Entomology from UC Riverside.  In 2014, he was inducted into the Green Industry Hall of Fame, and in 2016 he received the Arboriculture Research Award from the Western Chapter of the International Society of Arboriculture.

Delta farm tour gives GFI fellows a broader view of food system

The day-long tour, hosted by UC Agriculture and Natural Resources, began at a farm that is maintained to support wildlife in the breezy Sacramento-San Joaquin River delta region. The GFI fellows also viewed a habitat restoration project at LangeTwins Winery then watched freshly harvested cherries being processed at Morada Produce's packing plant. They wrapped up the day with a tour of a demonstration garden and a discussion of nutrition education at the UC Cooperative Extension office in Stockton. 

UC President Janet Napolitano, who, along with UC's 10 chancellors, launched the Global Food Initiative in 2014, met with the 17 fellows for lunch at LangeTwins Winery.

“We started the Global Food Initiative several years ago with the goal of creating a pathway to a sustainable, nutritious food future for the planet. A small, modest goal,” Napolitano said, adding that she is excited to learn about the fellows' projects.

The GFI fellows are working on projects that range from raising awareness about food production to analyzing the effects of climate change on pollination, and from efforts to make soils safe for growing food in urban areas to using food waste to fuel batteries.

UC Merced senior Ever Serna's GFI project is to educate his fellow college students about where food comes from, before it gets to the grocery store.

“The tour gave me a deeper understanding and appreciation about how food is developed and grown,” he said. “I think when I eat vegetables and fruits, I'm going to be more conscious of what I eat now.”

Reid Johnsen, a third-year Ph.D. student in agricultural and resource economics at UC Berkeley, Global Food Initiative fellow for UC ANR, and participant in the Graduate Students in Extension program, is working with UC Cooperative Extension in Sonoma County to study ranchers' preferences for different payment structures for conservation easement to compensate them for the ecosystem services provided by their land.

“To be able to see agriculture in action makes such a difference to me, to see the way the crops are produced and the variety that's out here,” said Johnsen. “The diversity of crops was not something I was aware of before coming on this trip.”

“I thought it was interesting to see a lot of different agricultural production systems,” said UC Santa Barbara senior and campus GFI ambassador Bryn Daniel, who works with student activists on student food access and housing security issues.

In addition to learning more about food production, the outing gave the fellows an opportunity to network with peers from other campuses.

“That's what I liked about today's meeting, just meeting everybody and getting these fantastic connections,” said Ryan Dowdy, a third-year Ph.D. student at UC Davis who is converting food waste into energy-producing microbial fuel cells.

“I think this program, and especially the fellowship, is really important for young scientists who dive into this really huge subject of global food,” said Claudia Avila, a graduate student at UC Riverside who studies trace metals in urban agricultural soils.

Best kept secret

In welcoming the UC GFI fellows, Glenda Humiston, UC vice president for agriculture and natural resources, said, “I have a feeling a lot of you aren't familiar with our division. As I travel around the state to different campuses, I keep being told that we're the best kept secret, which I personally do not think is a good thing." 

She explained that agricultural research has been part of the University of California since the land-grant institution's beginning in 1868 in Oakland. UC ANR has researchers on the Berkeley, Davis and Riverside campuses and UC Cooperative Extension advisors in the county offices, she said, adding, “Here in California, our advisors have very robust research programs.”

Farms are wildlife habitat

Michelle Leinfelder-Miles, UC Cooperative Extension delta crops advisor, and Brenna Aegerter, UCCE farm advisor in San Joaquin County, gave the fellows an overview of delta agriculture. Dawit Zeleke, associate director of conservation farms and ranches for The Nature Conservancy, explained why he farms 9,200 acres of corn, triticale, potatoes, alfalfa and irrigated pasture to enhance foraging habitat for sandhill cranes and other wildlife on Staten Island. The Nature Conservancy partners with UC Cooperative Extension along with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, California Department of Water Resources, Oregon State University, UC Merced and UC Davis to study the relationships between agriculture and natural resources.

The Pacific Flyway for migrating birds passes over the delta. “Eighty percent of waterfowl depend on agriculture for food,” Zeleke said. After wheat harvest, they flood the fields. “You should see it in September, October, November and December. Thousands of birds, ten thousand cranes use this place for habitat.”

Lodi region is zin-ful

En route to lunch, Paul Verdegaal, UC Cooperative Extension viticulture advisor for San Joaquin County, described the Lodi region's wine industry. There are about 750 growers, many of which are small family operations. While 10 to 15 acres used to be typical vineyard size, most have 100 acres to be sustainable and one family member works at an outside job. 

“Agriculture is a tough job and there is no guaranteed income,” Verdegaal said.

About 40 percent of the zinfandel in California is grown in the Lodi region, but there are several wine grape varieties planted. 

Pointing out the bus window to a vineyard interplanted with a crimson clover cover crop, Verdegaal said, “We do see interest in using as few chemicals as possible and using techniques of the integrated pest management program.”

After eating lunch at LangeTwins Winery in Acampo, the GFI fellows took a tour of the winery with the fourth- and fifth-generation owners, Randy Lange and Aaron Lange. The Langes are founding members of the Lodi Rules Program, which helps growers produce grapes and wines in a manner that is environmentally respectful, socially sensitive and economically sound. They pointed out an array of solar panels covering the grape press room that provide electricity. The Langes are planting native plants around the winery to reduce sedimentation, improve water quality and restore wildlife habitat along the Mokelumne River.

Bing is king of cherries

When the GFI fellows visited at the end of April, sweet cherry harvest had just begun in Bakersfield area orchards, and cherries were being packed and shipped in San Joaquin County.

“Hemmed in by rain to the north and heat to the south, cherry season is only eight to 10 weeks long,” said Joe Grant, emeritus UC Cooperative Extension farm advisor for San Joaquin County.

“While the Bing variety is still the mainstay of the California cherry industry because of its excellent eating and shipping quality,” said Grant, “acreage of other high quality and earlier-maturing varieties has increased in recent years to lengthen the harvest season. But Bing is still king.” Asked about the effects of climate change on cherries, Grant explained that warmer temperatures are reducing the number of winter chilling hours, which cherries need.

The fellows saw the hand-picked fruit being processed for packing at Morada Produce, a family farm in Linden that also grows walnuts, peppers and onions.

“Keeping produce cold is key to maintaining quality,” said Scott Brown, Morada's production manager, as the fellows watched fresh, cold water rain down onto the freshly picked sweet cherries. The leaves and stems floating to the top were removed as the red clusters glided in the water to the cluster cutter, which gently separated the clusters into individual cherries.  Gently conveyed through the plant in flowing water, the cherries were sorted by size and quality at the highly mechanized facility. Air ejectors spit out rejected fruit, so only 70 percent makes it into a packed box. 

“Fruit picked on Monday is packed Tuesday, then shipped to Korea, Japan, Australia and other export markets to be eaten by Friday,” Brown said.

The fellows were fascinated to see the steps taken to ensure high-quality cherries are cooled, sorted and packaged for shipping to stores and consumers. 

“It was just so much more complicated than I knew,” said Jess Gambel, a third-year Ph.D. student at UC San Diego who is studying the effects of climate change on bee pollination in squash plants.

Sustainable gardening

As the bus drove past almond orchards, Brent Holtz, UC Cooperative Extension director and farm advisor in San Joaquin County, described his orchard project studying the effects of removing almond orchards by grinding whole trees and incorporating them into the soil before replanting.

The tour wrapped up at the UC Cooperative Extension office in Stockton, with a discussion about how UC CalFresh and the Expanded Food and Nutrition Education Program help low-income Californians attain adequate nutrition and food security, followed by a tour of the demonstration garden maintained by the UC Master Gardener Program volunteers.

“There are more pollutants in urban runoff than in ag runoff,” said Karrie Reid, UC Cooperative Extension landscape horticulture advisor in San Joaquin County. Reid described how she and the UC Master Gardeners work with home and community gardeners to reduce pesticide and water use, and noted that a Water Use Classification of Landscape Species plant list, based on UC research, is available to help gardeners choose landscape plants.

“As a soil scientist, I really appreciated the recurring emphasis on soils as the foundation for agriculture,” said a fourth-year Ph.D. student at UC Berkeley and GFI fellow with Lawrence Berkeley National Laboratory. “From talking with The Nature Conservancy farm operator about how they were conserving carbon in those soils and doing wetlands management to hearing about special properties of the sandy loam soil in this part of the county, and talking with the Master Gardener folks about soil contamination issues.”                      

This is the third class of GFI student fellows. The undergraduate and graduate student fellows, representing all 10 UC campuses plus UC Agriculture and Natural Resources and Lawrence Berkeley National Laboratory, have helped further UC's Global Food Initiative efforts to sustainably and nutritiously feed the world's growing population by working on food-related projects and raising awareness of this critical issue.
