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.

To gain a better understanding of UC ANR's work in communities and to see firsthand how UC's Agricultural Extension programs engage with the public in an urban setting, the UC ANR Governing Council toured the South Coast Research and Extension Center in Irvine on Feb. 19.
The UC ANR Governing Council, which is chaired by UC Riverside Chancellor Kim Wilcox, visited UCCE specialist Alex Putman and UC Riverside graduate student Lindsey Pedroncelli's strawberry disease study, UC IPM advisor Cheryl Wilen's herbicide demonstration, and the urban landscape demonstration site, where Darren Haver, South Coast REC director and UCCE water resources advisor, conducts water studies. Niamh Quinn, UCCE human-wildlife interaction advisor, described her research on vertebrate pests ranging from rats to coyotes, and Beatriz Nobua-Behrmann, UCCE urban forestry advisor, and John Kabashima, emeritus environmental horticulture advisor, showed the council members shot hole borers and other pests that attack trees.
The UC ANR academics were joined by public and private sector partners, including Mark Lopez from OC Produce who is also the Orange County Farm Bureau president; Bryan Thompson, owner of Pest Options; Jenna Voss, South Orange County watershed manager for Orange County Public Works; Dave Erickson, Wildland Resources Planner for Orange County Fire Authority; Jim Hartman, deputy agricultural commissioner for Los Angeles County; Laura Krueger Prelesnik, vector ecologist for the Orange County Mosquito and Vector Control District; and Rick Howard, Orange County Mosquito and Vector Control District agency manager.
Foods grown at the center were incorporated in the lunch prepared by UC ANR culinary partners Andrea Machua of Culinary Underground, Kyle Manns of Taps Brewery and Lan Pham Zenti, owner of Jadetiger Tea.
“The day was both enjoyable and informative for all,” said Kathy Eftekhari, chief of staff to the vice president.

The South Coast Research & Extension Center is soliciting proposals for new research and extension projects, as well as prompting researchers with continuing projects to submit an updated Land, Labor, and Facilities form and 3-year report, if required, for project year July 1, 2020, through June 30, 2021.
Located on 200 acres in Orange County, South Coast REC research and extension projects and programs focus on a variety of agriculture and natural resource topics including: variety development, crop and landscape pest management, irrigation management, plant disease, rootstock development, and alternative weed control methods in managed systems. As reclaimed water is the main irrigation source provided to the center by the local water district, researchers can assist in the development of reclaimed water management strategies, an increasingly important resource for the long-term sustainability of agriculture and urban environments.
The center also continues to welcome the submission of research and extension projects addressing broader topics, such as the impacts of climate change on urban and agricultural ecosystems.
South Coast REC provides research projects with skilled farming equipment operators, irrigators, some limited indoor research facilities (for example, plant sample processing lab), and technical and management support. Projects led by UC academics receive funding directly from UC ANR and South Coast REC to reduce the actual cost of research and extension at the Center. Proposals from non-UC organizations will be considered if resources (space and labor) are available, but the full cost rate is charged plus the non-university differential (NUD currently is set at 33.7%).
Full cost recharge rates and UC ANR funding levels for UC-led research projects for South Coast REC for the 2020-21 year will be published after approval on the South Coast REC website (http://screc.ucanr.edu/Research/) this spring.
Proposals may be submitted into the REC Manage System via the South Coast REC website (http://screc.ucanr.edu/Research/Submitting_a_Proposal/) beginning March 1, 2020, and are due no later than April 15, 2020.
For questions about the research proposal process or research opportunities at South Coast REC, contact Darren Haver, center director, at firstname.lastname@example.org, or Chris Martinez, superintendent, at email@example.com.
Located on 200 acres in Orange County, South Coast REC research and extension projects and programs focus on a variety of agriculture and natural resource topics, including variety development, crop and landscape pest management, repository for germplasm collections (citrus, avocado, persimmon and cherimoya), irrigation management, plant nutrition and long-term impacts of changing rainfall patterns on native ecosystems. As reclaimed water is the main irrigation source provided to the center by the local water district, researchers have the opportunity to assist in the development of management strategies for a water source that will become increasingly more important to the long-term sustainability of agriculture and urban environments.
The center provides labor, equipment, research facilities and technical and management support at a reduced recharge rate to UC academics. For example, the current recharge rate is charged on an hourly basis of $9.99. Our goal is to minimize a significant increase in this rate from year to year. Proposals from non-UC organizations will be considered if resources are available but the full cost rate will be charged. Researchers are also directly charged for irrigation costs, which are currently $1.37 per 748 gallons of water (1 CCF).
Proposals may be submitted into the REC Manage System via the South Coast REC website http://screc.ucanr.edu/Research/Submitting_a_Proposal beginning March 22, 2016, and are due April 15, 2016.
The center's Research Advisory Committee will evaluate the proposed research and extension projects for scientific merit and regional appropriateness. Researchers will be notified by email.
