Report: Wastewater recycling essential to resilient water future for LA region

In a new report, Edith B. de Guzman and Gregory Pierce recommend actions to increase the amount and reliability of Los Angeles County’s recycled water supplies.

Wastewater recycling in Los Angeles is the focus of a new report released by the UCLA Luskin Center for Innovation and the UC Agriculture and Natural Resources. The report, Making the Most of Landmark Recycled Water Investments in Los Angeles: Technical Advisory Recommendations for the Region, was commissioned by Los Angeles Waterkeeper. The goal of the report is to support ongoing efforts to improve local water security and rely less on expensive, energy-intensive and increasingly unreliable water imports from faraway places, like the Sacramento-San Joaquin Delta and the Colorado River.

Experts involved in developing the report agree that expanding the use of recycled wastewater has emerged as a key, scalable water supply strategy that can offer certainty and reliability in the region in light of our new climate reality.

“Both the Metropolitan Water District of Southern California and the City of LA's Department of Water and Power have made significant investments in wastewater recycling, and they plan to do more,” said Bruce Reznik, executive director of LA Waterkeeper. “But there are a lot of moving parts and some critical decisions to be made in the short term if we're going to make significant progress toward reliable local water supplies.”

“The purpose of this report is to help decisionmakers see the full picture so they can prioritize and develop informed strategies for expanding and integrating the disparate wastewater recycling projects into a more cohesive wastewater system – all while taking community voices and environmental impacts into account,” he added.

Local leaders recognize the region must further invest in equitable, climate-smart, affordable local water strategies. LA County's Water Plan, released in late 2023, calls for 80% of water to come from local sources by 2045 (compared with approximately 40% currently). Four major centralized wastewater recycling projects, including two that are landmark in size and scope, have either broken ground or are in the active planning stages throughout Los Angeles County. Collectively, this regional effort may represent the most important water supply investment in the American West in the last half century.

“In many ways, our region has taken great strides toward embracing wastewater recycling,” said report co-author Edith B. de Guzman, UC Cooperative Extension water equity and adaptation policy specialist. “But we need a clearer pathway for how these projects can be built and possibly integrated into a more cohesive system. This report provides a blueprint for water agencies on the project design, community engagement and governance steps that must be made to ensure progress toward rapidly increasing our local water independence.”

Upwards of $20 billion in investment in wastewater recycling projects is planned for the coming years. But as local water and wastewater agencies make these investments, it's essential that they design systems to both maximize benefits and minimize impacts that could be damaging to people and the environment, all while ensuring water remains affordable. Just as importantly, the report flagged the need to effectively engage the public in key decisions to foster public trust in these emerging water technologies and facilitate coordination between agencies to create a resilient regional water supply system. 

Specific action items identified in the report are organized under eight principal recommendations:

  1. Take actionable steps on current key decision points pertaining to major recycling facilities. The report encourages agencies to make several decisions that will impact the design of the overall wastewater recycling systems imminently. These include resolving differences between the City of LA's Hyperion 2035 and Operation NEXT efforts, deciding whether to upgrade existing wastewater recycling infrastructure like the Edward C. Little Water Recycling Facility, and making key pipeline and routing decisions.
  2. Conduct a more nuanced regional analysis of system facilities, with an emphasis on evaluating distributed alternatives. While some assessment of a more distributed system has been undertaken, additional analysis is still needed on the issues of energy demand, the cost of distributing water under different alternatives, and impacts on aquatic and marine ecosystems.
  3. Identify and establish a structure for collaborative governance that enables agencies to work together to realize a regional advanced wastewater recycling network.
  4. Adopt a coordinated monitoring plan to ensure water quality is safeguarded for public and ecological health.
  5. Balance the adoption of Indirect Potable Reuse (IPR) and Direct Potable Reuse (DPR) with a near-term focus on IPR to the extent feasible and using DPR to fill in service gaps.
  6. Perform robust regional forecast and impact analyses to improve future-proofing of facility and network designs, maximize benefits, minimize harm, and avoid stranded assets.
  7. Design and execute a collaborative communication and community engagement strategy that offers a clear narrative, emphasizes the benefits of a secure water supply, meets the needs of water customers, and is delivered by trusted messengers.
  8. Coordinate across agencies on strategies to attract project financing while taking household affordability into account.

“This report is by no means the final word,” said co-author Gregory Pierce, research and co-executive director at UCLA Luskin Center for Innovation. “The point of this study is to provide guidance and spur discussion, and we hope and expect to see ongoing research and coordination on all of these issues.”

The report was informed by input from a Technical Advisory Committee of 20 people from fields including academia and think tanks, conservation advocacy, labor, the private sector, and current and former water district leaders not affiliated with the projects that are the focus of the report. This effort also benefited from the feedback and insight of more than 20 public agency representatives, including many from the City of Los Angeles (including Los Angeles Department of Water and Power and LA Sanitation and Environment), Metropolitan Water District of Southern California, Los Angeles County Sanitation Districts, Las Virgenes Municipal Water District, and West Basin Municipal Water District.

De Guzman named first UCCE specialist at UCLA 

Edith de Guzman

Edith de Guzman joined UC ANR Sept. 1 as a UC Cooperative Extension water equity and adaptation policy specialist. She is the first UCCE specialist to be based at UCLA.  

Her work investigates best practices for the sustainable transformation of the Los Angeles region and beyond, and has included research, demonstration projects, public policy and planning in the areas of water management, climate adaptation, heat mitigation and urban forestry. She tackles these topics through the lenses of urban planning, public health, behavioral sciences, biophysical sciences and public policy. 

She co-founded and directs the Los Angeles Urban Cooling Collaborative, a multisectoral partnership working to alleviate the public health risks of extreme heat. Their research has found that one in four lives currently lost to extreme heat could be saved if L.A.'s land cover had more trees and its built surfaces were more reflective, particularly where low-income communities and communities of color live and work.

From 2014 to 2020, de Guzman served as director of research at the Los Angeles-based organization TreePeople. Her projects at the nonprofit included the City of Los Angeles Stormwater Capture Master Plan; facilitating the creation of a Greening Plan with the Inglewood and Lennox communities; bringing to fruition multiple urban water-management demonstration projects; and leading an extensive study tour of Australia's response to its historic Millennium Drought and gleaning lessons for California. She also produced the first interactive, high-resolution public map and spatial analysis of Los Angeles County's urban forest. 

Having completed all of her studies at UCLA, de Guzman holds a Ph.D. in environment and sustainability, a master's degree in urban planning and a bachelor's degree in history and art history.

Van Cleave-Hunt named UCCE nutrition, health and food security advisor 

Veronica Van Cleave-Hunt
Veronica Van Cleave-Hunt began a new position within UC ANR on July 5 as the UC Cooperative Extension community nutrition, health and food security advisor serving Butte, Colusa, Glenn, Sutter and Yuba counties.

Before beginning her current position, Van Cleave-Hunt served for four years as a community education specialist for the CalFresh Healthy Living, UC program before becoming the program supervisor serving the same counties.

“Luckily, I already have my finger on the pulse of the community in these five counties just through my experience with CalFresh. I've been able to build rapport and connections with a lot of community partners and stakeholders,” said Van Cleave-Hunt.

As an advisor, Van Cleave-Hunt will focus on nutrition, education and healthy living efforts for people who are at a disadvantage, for example, those living in food deserts or experiencing food insecurity, a term used to describe the societal and environmental barriers to access and manage food. 

“Food security is about environment and access, but also skills related to food,” Van Cleave-Hunt said. “For instance, budgeting, even things like gardening, cooking and knowing how to prepare food so that you don't always have to buy ready-made food, or how to store things properly so that they last as long as possible.” 

According to Van Cleave-Hunt, food security includes skills that will help you get the most out of the food that you have.

Currently, Van Cleave-Hunt is compiling secondary data to conduct a needs assessment. In addition to engaging stakeholders such as resident service coordinators at low-income housing units or community organizations, she is also working with the State Council on Developmental Disabilities to develop healthy living trainings and curricula that will benefit communities in her counties.

She started her undergraduate career at Santa Rosa Junior College before transferring to California State University, Chico where she earned a bachelor's in nutrition and a master's degree in nutrition education.

Chelsey Slattery, former UCCE area nutrition, family, and consumer sciences advisor for Butte County, recruited Van Cleave-Hunt right out of college to be a UC Cooperative Extension community education specialist. Today, Van Cleave-Hunt holds the position that Slattery once did. 

Van Cleave-Hunt can be reached at vvancleavehunt@ucanr.edu and is based in Oroville.

Wayne joins UCCE as food systems advisor 

Laurie Wayne

Laurie Wayne joined UC Cooperative Extension on July 5 in Modoc County as a nutrition and food systems advisor for Modoc, Lassen and Siskiyou counties. Wayne will work with community members on healthy lifestyles, nutrition, food access and security, local food production, preservation and availability. 

Wayne brings years of high-desert food systems experience to her role: she owned and operated Locavore Farms in Fort Bidwell, helped found the Surprise Valley Saturday Market and Modoc Harvest, and was on the team that started the Modoc Harvest Food Hub. She also has worked supporting healthy communities for Oregon State University Extension in Klamath Falls, and at the High Desert Food and Farm Alliance in Bend, Oregon.

She earned a master's degree in TESOL (to teach English as a second language) from Portland State University and worked in school and community gardens with immigrants and refugees as part of her research project. She earned a bachelor's degree in Italian literature from UC Santa Cruz.

This job feels like the culmination of the farming, studying, supporting farmers and working in food systems she has done in the past 15 years, Wayne said.

“I'm especially interested in working on expanding access to affordable, healthy, local food year-round, including extending and preserving the harvest,” Wayne said. Her goal is to help everyone feel empowered to make healthy food choices, and she's learning what resources producers need to improve processing, transportation and production strategies, and overcome barriers that are unique to the region. 

To better understand both the food systems needs and the abundant food assets of northeastern California, she will be meeting with community members; state, local and regional nonprofits; schools and other organizations in the next few months. They will discuss ways to strengthen community food system resilience.

“It's all about healthy community members who can eat good local food without breaking the bank, and producers who can make a living feeding them,” Wayne said.

Based in Alturas, Wayne can be reached at lwayne@ucanr.edu and (530) 233-6400.

Hyland named UCCE environmental health sciences specialist 

Carly Hyland

Carly Hyland joined UC ANR in July as a UC assistant Cooperative Extension environmental health sciences specialist and assistant professor in the UC Berkeley School of Public Health.

She recently finished a mixed-methods project at Boise State University examining pesticide exposure and perceptions of the risks of pesticides among Latino men and women farmworkers in Idaho. In California, she is pursuing projects examining interventions to protect farmworkers from pesticides, extreme heat and wildfire smoke in collaboration with community partners.

“There are so many reasons I wanted to come back to Berkeley, and I think one of the biggest motivating factors for me was the collaborative environment focused not just on conducting innovative research, but also translating those findings into solutions to improve community health,” Hyland said. “Farmworkers are increasingly experiencing the health impacts of climate change on a daily basis, and this position will provide me with the resources and collaborations necessary to identify strategies to address these urgent issues.”

Hyland earned her Ph.D. in environmental health sciences and master's degree in global health and the environment, both from UC Berkeley, and bachelor's degree in environmental science from Carthage College in Wisconsin.

Hyland is based at UC Berkeley and can be reached at chyland@berkeley.edu and on X (formerly Twitter) @c_hyland1.

Smith-Helman joins Climate Smart Agriculture Program 

Bailey Smith-Helman

Bailey Smith-Helman joined UCCE Santa Cruz County on July 3 as a community education specialist with the UC ANR Climate Smart Agriculture Program.

Smith-Helman, who relocated from Washington, D.C., is excited to get back in the field and support Santa Cruz County growers with climate-smart agriculture practices and California Department of Food and Agriculture financial incentive programs.

CDFA programs provide financial incentives to eligible farmers and ranchers implementing new practices that maximize water efficiency, build soil health, and improve manure management. She is ready to assist interested growers with grant applications, project planning and implementation.

After graduating from Northwestern University with a bachelor's degree in political science and environmental policy, Smith-Helman moved to Paraguay to serve as an agriculture volunteer with the Peace Corps. In Paraguay, she worked closely with agricultural educators and local producers to develop education plans and lessons to engage high school students in agricultural coursework.

Smith-Helman is based in Watsonville and can be reached at bsmithhelman@ucanr.edu.

Sayre named UCCE agriculture and resource economics specialist 

Jay Sayre

James “Jay” Sayre joined UC Cooperative Extension and the UC Davis Department of Agriculture and Resource Economics as a CE Specialist on July 1. 

His role focuses on the economics of food supply chains across the state of California. Sayre aims to study policies to promote greater competition in food supply chains to benefit smaller-scale producers, understand the role of international trade in agriculture and its effects on Californian consumers, and assess how supply chains can best respond to a changing climate. 

Sayre is excited about combining economic theory and modeling approaches with understanding the needs of stakeholders in California to benefit food supply chains within California.

Sayre earned a doctorate in Agricultural and Resource Economics at UC Berkeley. His dissertation research spanned several disciplines, with chapters seeking to understand how agricultural supply chains lead regions to specialize in certain crops, the consequences of phytosanitary and other non-tariff barriers to trade, as well as developing methodology to accurately assess crop yields across large regions using satellite imagery and other sources of publicly available data. He earned a bachelor's degree in economics and mathematics from the University of Minnesota-Twin Cities. 

The Colorado native is looking forward to addressing a variety of issues relevant to California stakeholders. An ongoing project looks to develop fine-scale projections of future agricultural productivity for most of the major crops California produces, including crops that have historically not had such measures available, like perennials such as almonds, avocados and other fruits.

He hopes such information will be relevant not only for growers seeking to understand whether their land will be relatively more suitable in the future for different crops, but also agricultural intermediaries and policy makers looking to understand where production of certain crops may shift in the future.

Before joining Cooperative Extension and UC Davis, Sayre worked in Mexico, seeking to better understand the cross-border nature of supply chains that operate in both California and Mexico. He is proficient in Spanish and aims to increase the accessibility of extension to Spanish speakers. 

Sayre is based out of the Department of Agriculture and Resource Economics at UC Davis and can be reached at jsayre@ucdavis.edu.  

Valliere joins UCCE as weed and restoration ecology specialist 

Justin Valliere

Justin Valliere joined UC ANR on July 1 as an assistant professor of Cooperative Extension in invasive weed and restoration ecology at UC Davis. 

Valliere's research aims to evaluate how human-caused environmental change and invasive plant species impact native ecosystems, and how we can reverse this degradation through ecological restoration. The overarching goal of his research and outreach is to develop real-world solutions for land management in the face of global change.

“CE already is such an effective system for supporting agriculture, but it's also an important model for natural resource management and restoration,” Valliere told Trina Kleist, writer for the UC Davis Department of Plant Sciences. “There is a real need for help advising folks throughout the state about managing and restoring natural lands, and I'm excited to help bolster that.”

Prior to joining UC Davis, Valliere was an assistant professor of biology at CSU Dominguez Hills, a research fellow at the University of Western Australia, and a postdoctoral fellow at the La Kretz Center for California Conservation Science at UCLA.

Valliere earned his Ph.D. in plant biology from UC Riverside, and a bachelor's degree in biology from Green Mountain College in Poultney, Vermont. 

Valliere is based in the Department of Plant Sciences at UC Davis and can be reached at jmvalliere@ucdavis.edu

Hill named UCCE specialist in diversity and equity economics 

Ali Hill

Alexandra “Ali” Estvan Hill joined UC ANR and UC Berkeley's Department of Agricultural and Resources Economics on July 1 as an assistant professor of Cooperative Extension specializing in the economics of diversity and equity. 

From 2019 until she joined UC, Hill worked as an assistant professor of agricultural economics at Colorado State University. Her research centers around the U.S. agricultural workforce and seeks to demonstrate how a variety of factors impact worker well-being, quantified in terms of income or health impacts – and to make a business case for employers, in terms of implications for production or profits, to institute policies and practices that promote worker well-being.

Hired farmworkers contribute greatly to the racial, ethnic, cultural and socioeconomic diversity of U.S. agriculture; however, they are frequently not treated equitably and face a multitude of economic, physical, legal and emotional hardships in their personal and professional lives. Hill's research seeks to begin dismantling these inequities by finding avenues through which employers can increase worker well-being while maintaining or increasing profits. 

Hill brings extensive experience working with individual agricultural businesses to accomplish these objectives through enhancing firm data collection and analysis to provide an array of effective, efficient and actionable insights. 

She is building an extension program centered around advancing diversity, equity, inclusion and belonging in the agri-food system by enhancing the well-being of agricultural employees and other disadvantaged members of rural and urban agricultural communities. 

She earned her Ph.D. in agricultural and resource economics from UC Davis and master's degree in agricultural and applied economics and bachelor's degree in agricultural and consumer economics from University of Illinois, Urbana-Champaign.

Hill is based at UC Berkeley and can be reached at alihill@berkeley.edu and on LinkedIn www.linkedin.com/in/alexandra-estvan-hill.

UC ANR experts address emotional toll of drought

Preparing the American West for prolonged drought is the focus of a double issue of Water Resources IMPACT magazine. The California Water Commission staff are guest editors for this special open-access edition of the magazine, which is published by the American Water Resources Association.   

Faith Kearns, academic coordinator of University of California Agriculture and Natural Resources' California Institute for Water Resources, is among the authors delving into how drought impacts people and the environment and how we can better prepare for the inevitable. 

The first issue, published on Feb. 14, focuses on water scarcity issues confronting California and the ways these issues affect different sectors. 

In “Trauma, Care, and Solidarity: Addressing the Emotional Toll of Chronic Drought,” Kearns highlights the effects of drought on mental health. She points to the spike in suicide hotline calls when wells ran dry in Southeast Asian communities in California's Central Valley.

By listening to Southeast Asian farmers, Ruth Dahlquist-Willard and Michael Yang of UC Cooperative Extension were able to “lighten the load” for them by providing pragmatic support, Kearns writes.

“The scale of some of these highly emotional issues – drought, wildfires, climate change – can make them seem incredibly difficult, if not impossible, to deal with,” Kearns said. “At the same time, they are affecting everyone living in the western U.S. on a daily basis. I wanted to highlight and provide models based on work that people – whether they are researchers, clinical psychologists, or Cooperative Extension advisors – are doing right now to ease the way.”

The authors who contributed to the double issue are a diverse array of Tribal experts, academics, nongovernmental organization thought-leaders, water managers and water policy influencers, each of whom brings their own perspective on the topic of drought. Their expertise and perspectives in climate science, water policy and water management will help inform drought-related decision-making and support policies that better prepare the state to thrive during periods of prolonged water scarcity.

In addition to Kearns, the first issue includes articles contributed by:

  • Samantha Stevenson, University of California, Santa Barbara
  • Jay Lund, University of California, Davis
  • Ron Goode, North Fork Mono Tribe
  • Andy Fecko, Placer County Water Agency
  • Jeff Mount, Public Policy Institute of California, and Ted Grantham, University of California, Berkeley/UC Cooperative Extension
  • Nat Seavy and Karyn Stockdale, National Audubon Society
  • Kjia Rivers, Community Water Center
  • Cannon Michael, Bowles Farming
  • Michelle Reimers, Turlock Irrigation District

The January/February edition of Water Resources IMPACT magazine can be accessed, free of charge, on the American Water Resources Association website at https://www.awra.org under “Publications.”

The second issue, to be published in March, will focus on drought response, considering the options for adaptation. This two-part series complements the Commission's work on strategies to protect communities and fish and wildlife in the event of a long-term drought.

Your water-efficient landscape doesn’t have to be barren

UC climate-ready landscape trials identify low-water yet attractive plants

Good news: roses can be a part of your water-efficient landscape. Lorence Oki, UC Cooperative Extension environmental horticulture specialist in the UC Davis Department of Plant Sciences, identified rose cultivars that remain aesthetically pleasing with little water.  

Oki is the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials (UCLPIT), the California component of that project. These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water.

“There are some assumptions that pretty plants use a lot of water, like roses,” Oki said. “Everyone thinks they need a lot of water, but we've found some that don't, and they still look great. A water-efficient landscape doesn't need to look like a Central Valley oak-grassland in the summer. It can look really attractive.”

In 2021, Oki's team at UC Davis identified Lomandra confertifolia ssp. pallida "Pom Pom" Shorty and Rosa "Sprogreatpink" Brick House® Pink as two of the best low-water plants in the trial.

“The useful tip or information that is shared at the end of each trial is the selection and designation of plants as Blue Ribbon winners. These are the plants that looked good with an overall rating of 4 or higher throughout and were on the low (20%) water treatment,” said Natalie Levy, associate specialist for water resources, who manages the project at the UC ANR South Coast Research and Extension Center.

How plants earn a blue ribbon

Each trial year, the selection of new plants is based on research recommendations and donated submissions from the nursery industry. The landscape plants are trialed in full sun or 50% shade cover.

Irrigation treatments are based on the rate of evaporation and plant transpiration (evapotranspiration) measured through a local California Irrigation Management Information System (CIMIS) weather station that provides a reference evapotranspiration (ETo) rate.

Three levels of irrigation are provided to the plants equal to 20%, 50%, and 80% of ETo. The volume of water applied is the same at each irrigation based on soil characteristics, but the interval between applications varies with weather and the treatment. Using this method, irrigations for the 20% treatment are less frequent than the 80% treatment.

“The 20% treatment during the 2022 trial was irrigated an average of once per month while the 80% treatment was irrigated weekly,” explained Levy.

During the deficit irrigation trial, monthly height and width measurements are taken to determine the plant growth index. Monthly qualitative aesthetic ratings on a scale of 1 to 5 are determined for foliage appearance, flowering abundance, pest tolerance, disease resistance, vigor and overall appearance.

A second round of flowering abundance and overall appearance measurements are also taken to capture more of the blooming period. For example, UCLPIT identified in the 2020 trial at South Coast REC that the "Apricot Drift" rose had a mean overall appearance score of 3.5 out of 5, deeming it “acceptable to very nice” and a low water use plant within the Water Use Classification of Landscape Species or WUCOLS guide.

Project expands options for landscape planting

Nathan Lo, staff research associate, and Natalie Levy take monthly plant growth measurements (length, width and height) of the Center Stage® Red Crapemyrtle.
While attending UC Davis as a master's student, Karrie Reid, retired UCCE environmental horticulture advisor for San Joaquin County, assisted Oki with landscape water conservation research. The landscape plant irrigation assessments were initiated at UC Davis in 2004 and the UCLPIT project, now in its 20th year, originated from her master's thesis project from 2005 to 2007. A CDFA grant supported duplicating these fields at the South Coast REC in 2017.

“(WUCOLS) only has 3,500 plants in it. There are guesses that there are close to 10,000 cultivars in urban landscapes in California, if not more,” said Oki. “WUCOLS also didn't have numerical ratings. Instead, you'll see verbal ratings like ‘low water use' or ‘high water use.'”

The UCLPIT project has not only developed numerical recommendations for irrigation, but it has also added new landscape plants that are compliant with California's Model Water Efficient Landscape Ordinance. In fact, UCLPIT's data is one of the few sources that can be used to supplement WUCOLS.

Geographic diversity of trial sites adds to knowledge base

In addition to UC Davis and South Coast REC in Irvine, the trials have expanded beyond California as the Climate-Ready Landscape Plants project and is in progress at Oregon State University, University of Washington, University of Arizona and Utah State University thanks to a USDA/CDFA grant awarded in 2020.

Lloyd Nackley, associate professor of nursery production and greenhouse management at Oregon State University, is the principal investigator of the trial in the Portland metro area, which is entering its third year.

“People know that there are drought tolerant plants, but there are many. We're trying to highlight lesser known or newer varieties. And even though the trial is three years, most gardeners would hope that their garden lasts longer than that,” said Nackley.

One of the observations that Nackley recalls is of the Hibiscus Purple Pillar plant. Unlike the trial at South Coast, the Purple Pillar did not perform well in Oregon in the spring.

“It wasn't until August that we saw the plant bloom and begin to look like what we saw from South Coast in April,” Nackley said.

Jared Sisneroz, a research associate from UC Davis, uses a LI-COR instrument to measure the stomatal conductance of a leaf on an Oso Easy® Urban Legend® Rose plant.

Ursula Schuch, horticulture professor and principal investigator of the trial taking place at the University of Arizona, was also surprised at the range of performance among different plant types and the effects of irrigation, heat and temperature.

“This research will reassure green industry professionals that they can stretch their water budget to successfully cultivate more plants, watering them according to their needs instead of irrigating every plant according to the highest water-using plants,” said Schuch.

Although research is only conducted in the West, the hope is that there will be trials in other regions of U.S.

Doing so would yield comprehensive information about the plants and their performance in different climates. As extreme weather events persist in the U.S., disease pressure and risks do too. Trials throughout the country would provide location-specific data regarding disease susceptibility.
