Strategic Initiative Brief: Dahlke named Water Strategic Initiative leader
Following an open call, Helen Dahlke has agreed to take on the role of leader for the Strategic Initiative for Water Quality, Quantity and Security.
Dahlke is associate professor in integrated hydrologic sciences in the UC Davis Department of Land, Air and Water Resources. She brings a rich history of experience having completed her undergraduate and master's degrees in her native Germany before earning her Ph.D. at Cornell University. After her Ph.D., she did postdoctoral work at Stockholm University in Sweden before joining UC Davis in 2013.
Dahlke's current research interests include surface water – groundwater interaction, water resources management, vadose zone transport processes, and applications of DNA nanotechnology in hydrology. She comes with a broad appreciation of the multiple roles for addressing issues facing water across the state from the mountains to the sea. One of her main research efforts focuses on testing the feasibility of using agricultural fields as recharge sites for groundwater replenishment.
“We welcome and thank Helen for adding this new role to her ongoing activities,” said Mark Bell, vice provost for strategic initiatives and statewide programs. “The SI leaders are the champions for the broad umbrellas of work across the organization.”
The Strategic Initiatives help people connect while helping unify, communicate and advocate for UC ANR's work across the state. The SI leaders are part of Program Council, which provides input for programmatic policy and direction for the organization.
ANR team wins ANREP educational materials award
The “Ranch Water Quality Planning Instructor's Guide and Lesson Plan” won the Association of Natural Resource Extension Professionals bronze award in the category of Book or Comprehensive Program Curriculum.
The team includes Toby O'Geen, Bill Birmingham, Brooke Latack, DJ Eastburn, Dan Macon, David Lewis, David Lile, Devii Rao, Fadzayi Mashiri, Jeffrey Stackhouse, Jim Downing, Josh Davy, Julie Finzel, Kenneth Tate, Laura Snell, Leslie Roche, Lucien Crowder, Matthew Shapero, Michael Lennox, Morgan Doran, Randy Dahlgren, Rebecca Ozeran, Rob Atwill, Sandra Osterman, Stephanie Larson, Theresa Becchetti and Tracy Schohr.
The Ranch Water Quality Planning Instructor's Guide and Lesson Plan represents the evolution of the UC Ranch Water Quality Planning Partnership and shortcourse program. The Instructor's Guide was published in two formats – a dynamic PDF document and an HTML webpage. Both formats integrate 29 educational and instructional videos in a curated playlist on the UC ANR YouTube channel. This comprehensive training resource gives instructors the tools to plan and deliver a shortcourse that trains private and public grazing land managers to develop land stewardship and water quality management plans. The Instructor's Guide provides a wealth of contemporary information and resources about water quality management on rangelands and supports adaptation of the curriculum content and elements to local conditions and needs. The team began outreach and extension of these resources in November 2020. Through January 2021, the materials were downloaded 110 times and received 240 unique page views.
$1 million grant expands climate-ready landscape plants program
A research project initiated in the Department of Plant Sciences at UC Davis evaluates landscape plants in two-year trials under varying irrigation levels to determine the best irrigation level for optimal plant performance in regions requiring supplemental summer water. Creating water budgets is required by California's Model Water Efficient Landscape Ordinance (MWELO), and the results from these research trials help landscape professionals and home gardeners make informed decisions when specifying, selecting or promoting low water-use landscape plant material.
This year, the CDFA/USDA Specialty Crops Multistate Program funded a new Climate Ready Landscape Plants project, which will replicate the successful fields that are currently installed at UC Davis and UC ANR South Coast Research and Extension Center in Irvine.
Loren Oki, UC Cooperative Extension specialist in the UC Davis Department of Plant Sciences, is the lead principal investigator and collaborators include researcher Jared Sisneroz; project leader Karrie Reid, UC Cooperative Extension environmental horticulture advisor in San Joaquin County; and Darren Haver, UC Cooperative Extension water resources and water quality advisor and director of South Coast REC and UCCE in Orange County.
Under Oki's oversight, this new $999,992 grant will support the development of additional fields at several western universities:
- University of Washington, Soo-Hyung Kim
- Oregon State University, Lloyd Nackley and Ryan Contreras
- Utah State University Center, Youping Sun and Larry Rupp
- University of Arizona, Ursula Schuch
Conducting these new experiments on landscape plants at diverse sites across the western U.S. will reveal differences in recommendations since irrigation guidelines for landscapes vary depending on climate and soil type.
The initial project was initiated as Reid's master's degree thesis research in 2004, with Oki as her major professor, and has been ongoing since then.
Project descriptions, results and images can be seen at the UC Landscape Plant Irrigation Trials website at https://ucanr.edu/sites/UCLPIT.
Names in the News
Kron named north coast IPM advisor
Cindy Kron joined UC Cooperative Extension as area-wide IPM advisor for Sonoma, Napa, Mendocino and Lake counties in September 2019.
Before joining UCCE, Kron studied the three-cornered alfalfa hopper as a research entomologist for USDA in their Crop Disease, Pests and Genetics research unit. She tested cover crop species as feeding and reproductive hosts of the three-cornered alfalfa hopper in addition to testing commercially available biocontrol agents against the different life stages of the treehopper. She collaborated with a UC Davis colleague to create a degree-day model that predicts the ideal timing to implement cultural control measures with the greatest impact on treehopper populations.
Kron has researched a variety of insects including a two-year vineyard study on the population dynamics of Virginia creeper leafhopper, western grape leafhopper and variegated leafhopper. For her dissertation, she investigated the biology and behavior of the three-cornered alfalfa hopper and its relationship with vineyards. She also studied the effects of temperature on the developmental rate of the invasive European grapevine moth and reared brown marmorated stink bugs for USDA fumigation studies.
“My experiences have motivated me to help growers, stakeholders and the industry solve agricultural pest management problems through applied research and identifying IPM strategies and tactics that are economically feasible and implementable while having the lowest environmental impact,” Kron said.
Kron earned her bachelor's degree in viticulture and enology, with a minor in agricultural pest management, and her doctorate in entomology at UC Davis.
She is based in Santa Rosa and can be reached at ckron@ucanr.edu.

Harper honored as Range Manager of the Year
The California-Pacific Society for Range Management honored John Harper, UCCE livestock and natural resources advisor for Mendocino and Lake counties, with its Range Manager of the Year Award.
“He has advanced an exceptional program of extension education and public service that has been exemplary in gathering and evaluating scientific information and extending information to the range livestock industry and agencies locally and statewide,” wrote Mel George, emeritus UCCE range specialist,in his letter nominating Harper for the award.
Early in his career, Harper helped local ranchers evaluate grazing management practices and develop ranch management plans to address water issues associated with grazing and rangelands in the early 1990s. He was instrumental in developing the Rangeland Watershed Program's Ranch Water Quality Planning Short Courses and associated educational materials that led to the development of water quality plans for more than 2 million acres by more than 1,000 ranchers in California, according to George. In 2012, the Western Extension Directors bestowed an Award of Excellence on the Rangeland Watershed Program.
An early adopter of social media for outreach, Harper developed the blog UCCE Livestock and Range Topics and integrated the use of Facebook, Twitter and LinkedIn into his suite of information delivery methods.
In 2012 Harper became California's representative to the Rangeland Partnership, which is responsible for the Rangelands West and Global Rangelands website. He provided leadership to industry in the use of social media to communicate about rangelands and their management.
Harper also improved access to university information and publications by the California Cattlemen's Association and other agricultural organizations. He has been developing new content, digitizing and archiving old publications and revamping the California Rangelands website and the UCCE Livestock & Range Beef Cattle web page.
Over the last few years, Harper has invested considerable time in economic development in Mendocino and Lake counties.
“He has been a central figure in the development of plans for a multi-species slaughterhouse to serve niche marketers on the north coast,” George wrote. “This would create jobs and strengthen the farm-to-consumer marketing of meat products. Likewise, he has worked with individuals to develop wool processing facilities and cheese making enterprises that will increase economic activity and potentially create jobs.”
For many years, Harper has organized what may be the only sheep shearing school in the U.S., creating new careers for the students while filling a need for sheep shearers. All 28 slots of his 2019 Beginning Sheep Shearing School were filled within 2 minutes of registration opening.
Harper received the award at the California-Pacific Society for Range Management Section Meeting Oct. 17.
New annual report shows how UC ANR is improving California life with science-based solutions
Of the hundreds of ways UC ANR impacts California lives and livelihoods, 40 are highlighted in the new publication, Working for the Benefit of All Californians: 2018 UC ANR Annual Report. A limited number of printed copies are available. Email jennifer.caron-sale@ucop.edu to request paper copies.
UC ANR has identified public value statements that reflect the breadth of its efforts. Academics and staff are working to promote economic prosperity, safeguard sufficient safe and healthy food for all, protect the state's natural resources, promote healthy people and communities, develop a qualified workforce, build climate change resilience in communities and ecosystems, and develop an inclusive and equitable society. These values touch every person in the state.
During the period covered in the new report, robust research and education programs supported agricultural communities. For example, UC ANR scientists improved the ability to predict beet curly top virus, avoiding losses approaching $100 million in processing tomatoes. A workshop offered by UC ANR educators on low-stress livestock handling convinced all the participants to incorporate the practices on their ranches. Online and in-person workshops provided to urban farmers resulted in new food safety plans for nearly all of the growers involved.
Families, farmers and natural resource managers are facing the prospect of climate change and looking for ways to continue prospering under uncertain conditions. Increasingly ferocious wildfires are causing serious losses to ranchers. UC ANR provided information on management practices to safeguard resources, prevent soil erosion and estimate the cost of forage losses so ranch owners can prepare loss claims. UC ANR has been instrumental in development of a website, Cal-Adapt.org, a clearing house to collect and disseminate climate change data.
Families and youth are a focus of UC ANR nutrition research, nutrition education and programs such as 4-H and CalFresh Healthy Living, UC. One UC ANR researcher collaborated with the Karuk, Yurok and Klamath tribes to identify culturally sound solutions to reduce food insecurity. In two Northern California counties, students were introduced by UC ANR educators to 36 local produce items. Their selection, consumption and interest in the produce served at lunchtime increased. UC ANR piloted a program that gets Latinx youth outside for environmental education.
Making food safer, enriching children's lives, extending reliable nutrition education and improving the productivity on California farms and ranches add up to significant value to the recipients of the services and to all Californians by making the state a better place to live and work.
