Greetings from UCCE Central Sierra!

We hope you’re staying cool in the heat of summer and encourage you to read the UC Master Gardeners Water Saving Tips to help conserve water during this period of drought. While it is exciting to see so many groups, meetings, and workshops returning to an in-person platform, we’re finding for some things, a virtual format still works better for our clientele. Either way, Central Sierra staff continue their commitment to bring researched based information to our community, regardless of format. Read on to meet some of the new faces working with UCCE Central Sierra, and as always, thank you for your continued interest in our news, workshops, and events! Take care, stay cool, and stay healthy.

Farm Advisor Wunderlich Retires After 22 Years
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 curiosity — as well as her dedication to meeting the wide-ranging needs of local communities — led her to develop expertise in an 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 retired 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 degree in plant protection and pest management from the University of California, 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 in Placerville. “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 integrated pest management 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 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 said she 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 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.”

Kestrel Grevatt
Kestrel grew up in Vermont before attending the University of Southern California to obtain a B.S. in Aerospace Engineering. While in school she worked seasonally on fuels crews with conservation corps and as a wildland firefighter for the U.S. Forest Service. Finding a passion for field work and fire management, post-graduation she accepted a position with the American River Hotshots on the Tahoe National Forest. Working on forests throughout the U.S. and witnessing our shifting fire regime and the profound impacts of wildfires on communities and ecosystems inspired Kestrel to get involved in more long-term sustainable forest management and fire prevention efforts. She left fire suppression to work as an AmeriCorps Fellow through the Grizzly Corps program and was placed with the Berkeley Forests network of timber and fire research properties. After her term, Kestrel continued working with Berkeley Forests as a Crew Lead and now as Intern Forester. Through multiple seasons of suppression, prescribed burning, and harvest and fuels treatment implementation and oversight, Kestrel has developed a broad range of forestry and fire experience.
Daylin Wade
Daylin has several years of experience in forest management and monitoring in the Sierra Nevada. She studied physical geography and forestry at UC Berkeley and went on to work at UC Berkeley's Blodgett Forest Research Station. She managed forest health monitoring efforts for the California Tahoe Conservancy's Forest Habitat Enhancement Program, tracking the effects of forest thinning projects and wildfire on vegetation, songbirds, and more. Daylin also collaborated with UCCE on a publication (in press) reporting the effects of post-wildfire treatments on shrub dynamics in the Tahoe Basin. She is very excited to join UCCE's efforts to build resilience in Sierra Nevada forests by engaging with communities affected by fire. Daylin currently lives in Penn Valley, Nevada County where she helps to manage her family's 10-acre organic vegetable farm part-time. She loves growing vegetables, flowers and medicinal plants, recreating outdoors whenever possible (especially in the Yuba River and the High Sierra) and introducing her two-year-old daughter to these, and other good things in life.
