Ask a rancher: Surveys draw on hard-won wisdom for surviving drought
Roche team lands $1 million to help ranchers stay strong
California ranchers benefit when they plan ahead for extreme weather variability, according to rancher surveys and interviews conducted by a team headed by Leslie Roche, a professor of Cooperative Extension in the UC Davis Department of Plant Sciences.
But while wise planning and climate-smart adaptations helped ranchers survive the state's record-breaking 2012-2016 drought, those strategies by themselves were not enough, ranchers reported. Nearly 50 ranchers shared their experiences, and their collective wisdom is summarized in a paper written by Grace Woodmansee. She completed her master's degree with Roche and is now a UC Cooperative Extension livestock and natural resources advisor for UC Agriculture and Natural Resources in Siskiyou County.
Building on that work, Roche and members of the statewide team have landed a $990,000 federal grant to help ranchers stay strong. The team includes colleagues from the University of California Agriculture and Natural Resources and partner organizations. The project draws on members' diverse expertise and regional knowledge rooted in UC Cooperative Extension, while at the same time linking up with trusted networks at the local level.
Both Woodmansee's paper and the new grant are based on more than a decade of surveys and interviews with ranchers and other agriculturalists. That work all points to the economic and social barriers that hinder producers from adopting the climate-smart practices that could help them stay profitable amid the changes to come.
“It's really important to listen to agricultural producers – the people who live and work on the land – and draw on their experiences to develop practical solutions,” Roche said. “Extension can play a key role in sharing this valuable knowledge statewide, so others can learn from it and, hopefully, apply it to navigate their own challenges.”
Partners on the project include individual livestock producers, statewide livestock organizations, local conservation organizations and local agencies. Programs like this could become an example for ranch managers across the American West.
Cattle is California's No. 3 agricultural commodity, with cattle and other livestock worth about $3 billion in 2021, the state Department of Food and Agriculture reported. In addition to facing climate change, the sector is beset by rising costs, high interest rates, wildfire impacts and land use pressures. These additional challenges make it crucial for people managing the state's 14,000 livestock operations – counting beef, sheep and goats – to take steps now to survive future droughts.
Rangeland drought strategy: Mix up the livestock
In the past 12 years, ranchers have increasingly adopted sustainable agriculture practices to cope with drought and other threats, Woodmansee and colleagues found.
A key finding from the surveys is the enormous benefit amid drought of grazing more than one kind of animal on rangelands, Woodmansee wrote. Although most ranchers interviewed grazed only one species during the drought, typically cattle, the few who mixed up their livestock reported doing better economically. Because they have different grazing habits, stock such as sheep and goats can take advantage of different kinds of forage and broaden a rancher's economic base.
In addition, ranchers who used genetic information to think ahead about culling their herds, when that step became necessary, were left with a stronger remainder, Woodmansee wrote.
Ranchers also found it was important to have plans both for preventing problems and reacting to them, Woodmansee added. But surveys done ahead of the 2012-2016 drought, and interviews done four years in, also revealed that only a little more than half of ranchers had planned ahead.
“There is a substantial opportunity to increase preparedness by aiding ranchers in developing drought management plans,” Woodmansee wrote. But she advised, “drought plans are not ‘one size fits all,' and policy must be designed to support drought adaptation and mitigation strategies at the ranch level.”
Grant part of nationwide effort
Roche and team's $990,000 grant comes from the United States Department of Agriculture through the National Resources Conservation Service. It's part of a $22-million, nationwide effort to help American ranchers overcome these and other barriers they face to adapting. Based on all they've learned through the surveys and interviews, the team is now launching a comprehensive education, outreach and training program. Their own wide range of expertise and networks reach deep into ranching communities, and they'll leverage those, too. 
UC Cooperative Extension will have an important role in that work, as a trusted source of information. Training also will embrace conservation planners and technical service providers who work with ranchers.
“Activities will include workshops, field tours and demonstrations on conservation practices to address local natural resource concerns,” the team wrote in their proposal. Their work also “will target opportunities to support underserved communities, including new and beginning ranchers.”
They'll also add resources specifically about the state's grazing lands to the California Climate Hub, a website developed by USDA to provide the latest information to help producers statewide adapt to new climate realities.
People trained in all these areas must be brought up in the ranks: The project calls for networking, mentoring and hands-on learning to spark career choices among young people, and grow skills among beginning ranchers and early career natural resource professionals.
Scientists co-leading the project are Tracy Schohr and Dan Macon of UC Cooperative Extension; Roselle Bush and Gabriele Maier, both UC Davis assistant professors of Cooperative Extension; and Steven Ostoja, California Climate Hub director. The project will provide opportunities for a broad range of UC ANR colleagues as well, Roche said.
Partnering organizations include the Sierra Valley Resource Conservation District, the California Cattlemen's Association, the California Wool Growers Association, the California Rangeland Trust and the UC Davis School of Veterinary Medicine.

Tips on care of backyard chickens, sheep, goats compiled on new website
UC Cooperative Extension expertise available in English and Spanish on small-scale livestock production, pasture management, pests and predators, weed management and emergency preparedness
A team of University of California Agriculture and Natural Resources advisors has created a new comprehensive website for small acreage landowners in California and beyond. The Small Acreage Landowners website, at https://ucanr.edu/sites/smacreage, is designed to be a one-stop shop for backyard livestock producers, youth raising livestock, and other small acreage landowners. Information on livestock husbandry, pasture management, pests and predators, weed management and emergency preparedness is in English and Spanish on the website.
“We've seen an amazing growth in interest in small-scale livestock production throughout California in the last four years,” said project leader Julie Finzel, UC Cooperative Extension livestock and natural resources advisor for Kern, Tulare and Kings Counties. “Folks in our communities are hungry for knowledge about how to care for their land and their animals – from urban chickens to backyard goats and sheep.”
The website includes specific information for most common livestock species, as well as links to sites with more in-depth information about specific topics. Other pages include information on protecting livestock and property from pests and predators, controlling common weeds and protecting water quality.
The site also provides links to a variety of other UC ANR resources, including wildfire information from the Fire Network, and videos and webinars from the UC ANR Managing Land & Livestock on Small Acreage Webinar Series.
“We're excited this new website will make science-based information available to a wider audience,” said Finzel. “Most of our educational programming has focused on commercial livestock production.”
In addition to Finzel, a team of UC Cooperative Extension livestock advisors contributed to the project, including Theresa Becchetti (Stanislaus and San Joaquin counties), Brooke Latack (Imperial, Riverside and San Bernadino counties) Dan Macon (Placer, Nevada, Sutter and Yuba counties), Devii Rao (San Benito, Santa Cruz and Monterey counties), Rebecca Ozeran, former UC Cooperative Extension livestock advisor for Fresno and Madera counties and Flavie Audoin, former UCCE advisor for the Central Sierra now rangeland management extension specialist at University of Arizona. UC ANR technician Sequoia Williams in Placer County compiled information and designed the webpages.
The Small Acreage Landowners website was created in part with funds from a USDA-NIFA Renewable Resources Extension Act grant.
Updated March 6, 2024, to add Flavie Audoin as a contributor to the website.
UCCE advisor’s breadth of experience and education support ranchers’ economic viability
This is one of a series of stories featuring a sampling of UC ANR academics whose work exemplifies the public value UC ANR brings to California.
Livestock and natural resources advisor Dan Macon came to UC Cooperative Extension three years ago with much more than a formal education in integrated resource management and agricultural and managerial economics.
He had years of hands-on experience running a successful foothill sheep operation, toiling long days and often into the night tending animals, irrigating pastures, training livestock guardian dogs and managing forage.
“I came to this position mid-career,” said Macon, who also accumulated skills working for a family auction company and in various capacities for the California Cattlemen's Association, the California Rangeland Trust and USDA's Natural Resources Conservation Service.
When Macon bought his ranch, he needed help dealing with invasive Himalayan blackberries. He called Roger Ingram, the UCCE livestock and natural resources advisor in Placer and Nevada counties from 1997 to 2017.
“Roger helped me take care of the problem,” Macon said. “Following his recommendation, I bought goats and they grazed the blackberries into submission. Now the grass can out-compete the invasive plants. We've turned the area into grassland.”
Macon began volunteering for UC Cooperative Extension by teaching fellow ranchers about his experiences raising sheep, managing rangeland and raising and training livestock guardian dogs. Macon was a presenter at Ingram's annual California Multi-Species Browsing Academy.
“I finally recognized that the parts of my earlier jobs that I most enjoyed involved things I'd be doing on a daily basis as a farm advisor – teaching and research,” Macon said. He earned a master's degree from Colorado State University and applied to succeed Ingram after his retirement. Macon also took on the role in Sutter and Yuba counties, succeeding Glenn Nader.
Livestock production in the Sierra Nevada foothills ranks among the top five agricultural commodities. Economic viability is a major issue. Macon's research and extension program is focused on ranch economics and business management, drought resilience, predator-livestock coexistence and irrigated pasture management.
At the UC Sierra Foothill Research and Extension Center in Browns Valley, Macon is conducting research that will help ranchers make decisions about maintaining a cattle herd when faced with impending drought. Even when the weather forecast is dry and forage isn't growing at a sufficient pace, ranchers can be reluctant to sell off their cattle.
“Science tells us you shouldn't try to feed your way out of a drought,” Macon said. “Ranchers want everything to stay the same. They want to maintain their genetic potential and keep cows that are familiar with the area.”
The research will compare cows weaned on a traditional weaning schedule with others that are weaned early.
“The cattle will be out on the range from March to early September under different parameters,” Macon said. “We're also tying in economics, the value of genetic potential and the value of having cows who know the landscape.”
Macon is securing funding to conduct research on livestock guardian dogs in different production settings. Using low-cost GPS technology developed at New Mexico State University, Macon plans to study the relationship between dogs, predators and livestock in terms of space and time.
“One unknown is whether they displace predators or disrupt predatory behavior,” Macon said.
Macon uses livestock guardian dogs on his ranch and will be able to draw on his own experiences in designing the study. He recently wrote a fact sheet on guardian dog selection with UCCE human-wildlife interaction advisor Carolyn Whitesell.
“We've had great success with our guardian dogs,” he said. “But not everyone has that level of success. Using scientific tools like remote sensing and GPS technology will give us more details about wildlife-guardian dog-livestock interactions.”
During this year's shelter-in-place, Macon has become more creative in reaching out with scientific ranching information. He and large-scale sheep producer Ryan Mahoney of Rio Vista created a weekly podcast, “Sheep Stuff Ewe Should Know.” Early episodes cover such topics as risk management, the effects of COVID-19 on the sheep industry and livestock guardian dogs. The podcast is available on Spotify and other mobile podcast apps.
Macon developed a new bi-weekly webinar series, “Working Rangeland Wednesday,” with UCCE specialist Leslie Roche and UC Davis graduate student Grace Woodmansee. Recordings are posted on YouTube.
Traditional, one-on-one farm calls are also a part of Macon's extension program. He conducts five or six a month. Even so, the COVID-19 pandemic prompted Macon to begin remote advising. Soon after Gov. Newsom's shelter-in-place order was issued, Macon got a call from a woman whose ewes had recently given birth.
“She thought the lambs weren't doing well and wondered what she could do,” Macon said. “We both had Facetime, so I asked her to show me what the sheep looked like. I was able to assure her that things were normal and suggested bottle feeding. I talked to her several times over the next couple of days, and she was able to save the lambs.”
Most queries from local ranchers center on pasture or grass management, species composition, fencing, paddock design and animal husbandry. Last year, ranchers called with blue oaks suddenly and inexplicably dying on their land.
“The trees had no visible injuries. Ranchers were wondering if it was a lingering effect of drought or due to habitat fragmentation,” Macon said.
Macon contacted UC Cooperative Extension plant pathology specialist Matteo Garbelotto, a UC Berkeley-based tree disease expert. The scientists collected scorched leaves, wood samples and soil near the trunks of the dead or dying trees. They found evidence of fungi Botryosphaeria corticola and B. dothidea in wood chips collected at breast height. However, blue oak is not an official host for the two pathogens in the USDA fungus-host database.
The researchers believe that recent droughts and climate change may be causing an increased and widespread susceptibility of blue oaks or that an unknown pathogen may be increasing the susceptibility of blue oak to the canker disease. The progress made in solving these mysterious blue oak deaths was published in the most recent California Agriculture journal and will be the subject of continuing investigations in the future by Macon and his colleagues.
New UC studies outline costs of producing irrigated pasture in the Sierra Nevada foothills
Two new studies on the costs and returns of establishing and producing irrigated pasture in the Sierra Nevada Foothills have been released by UC Agriculture and Natural Resources' Agricultural Issues Center. Ranchers in Nevada, Placer and surrounding counties may find the cost estimates useful for planning.
Based on 40 acres of leased ground, the studies focus on establishment by tilling the soil, using conventional cultural practices and re-establishment of pasture using no-till cultural practices. The two separate studies, by Dan Macon, UCCE livestock and natural resources advisor, and Donald Stewart of the Agricultural Issues Center, estimate the cost of establishing or re-establishing a pasture and producing pasture over its 30-year life span.
There are two methods of establishing a pasture. One method uses conventional cultural practices, destroying the existing pasture and preparing the soil, or seed-bed, using conventional tillage practices.
The other no-till method of re-establishing the pasture uses high-intensity grazing and herbicides to destroy the existing pasture and plant new pasture using a no-till seed drill.
Their analysis reports the differences of machinery costs and methods. The reported prices for materials, equipment and custom services are based on January 2020 figures.
UC Cooperative Extension farm advisors, specialists, grower cooperators and other agricultural associates provided input and reviews. The authors describe the assumptions used to identify current costs for pasture establishment and production, material inputs, cash and non-cash overhead. A ranging analysis table shows profits over a range of prices and hay yields.
The new studies are “2020 - Sample Costs to Establish or Reestablish and Produce Irrigated Pasture in the Sierra Nevada Foothills, Flood Irrigated” and “2020 - Sample Costs to Produce Irrigated Pasture in the Sierra Nevada Foothills, Flood Irrigated.”
Both studies can be downloaded from the UC Davis Department of Agricultural and Resource Economics website at http://coststudies.ucdavis.edu. Sample cost-of-production studies for many other commodities are also available on the website.

UC ANR research to determine future climate change impacts today
Scientific evidence of a warming climate in California and across the globe is clear, but the impacts on ecosystems and agriculture are still difficult to predict.
Sophisticated computer models are used to forecast future climate. Understanding that temperature and precipitation levels will change in the future does not tell the full story: UC Agriculture and Natural Resources researchers also want real-world experience under those future conditions.
Moreover, some agricultural operations have higher sensitivity to the changes than others. Rangeland forage is particularly sensitive to climate changes since, unlike irrigated agriculture, ranchers rely solely on precipitation. They have no control over how much and when it rains.
“It's tricky business,” said rangeland expert Jeremy James, the director of the UC Sierra Foothill Research and Extension Center in Browns Valley. “It's not easy to forecast. We have to address the uncertainty in a realistic manner.”
Discovering climate change impact on rangeland
In order to study different climate projections on rangeland, James and Maggi Kelly, director of the UC ANR Informatics and Global Information Systems special program, have begun development of a research site that will allow scientists to manipulate the temperature and rainfall on sections of rangeland to understand what would happen under predicted weather scenarios.
“We need to know how rangelands will respond when conditions change,” James said. “Will we grow more, but dry out earlier? Will we have more medusahead (an undesirable rangeland weed) or more soft chess (a high quality forage)?”
When complete, 16 shelters on steel tracks will be connected to computer systems and hydraulic motors to move them up or down a research plot. The shelters and other equipment will allow scientists to precisely control the amount of precipitation (or irrigation water) that rains onto the plot. Other systems will give researchers control of air temperature.
“This facility isn't designed for one type of research,” James said. “It is designed to conduct a wide variety of research by scientists over the next several decades. With this setup, we can look at the effect of climate change on soil biological communities, soil carbon, insect communities, plant-insect interactions and oak seedling recruitment.”
The research results from the project should provide ranchers and land managers a better understanding of how climate change may impact agriculture and ecosystem function on rangeland while also providing important information on how to minimize impacts of these changes.
Some aspects of the research facility's development are not covered with funding from the National Science Foundation. The scientists are looking for additional support to complete the project.

Current work underway at the Sierra Foothill Research and Extension Center
The Sierra Foothill REC, a 5,000-acre facility on the Yuba River, has supported research, education and outreach in the Sierra foothills since 1960. Multiple lines of research are being conducted at SFREC. During a recent workshop, scientists from UC Davis, UC Berkeley and UC Cooperative Extension shared a sampling of their work at SFREC.
UCCE livestock and natural resources advisor Dan Macon described a project aimed at helping ranchers make decisions about maintaining a cattle herd when faced with impending drought. Ranchers are reluctant to sell off their cattle even when the near future weather forecast is dire.
“Science tells us you shouldn't feed your way out of a drought,” Macon said. “But you want everything to stay the same. You want to maintain your genetic potential and keep cows that are familiar with the area.”
Working with ranchers, the research project will compare management practices to determine the best way forward when the future looks meteorologically bleak.
“We're assigning cows to a traditional weaning and early weaning groups,” Macon said. “They'll be out on the range from March to early September under different parameters. We're also tying in economics, the value of genetic potential and the value of having cows who know the landscape.”
Research by University of Oregon post doctorate researcher Ashley Shaw is looking into whether compost applied to rangeland will help mitigate climate change by sequestering more carbon, and also benefit forage under drought by increasing the soil's water-holding capacity and improving nutrient delivery.
Preliminary results are promising. A single application of 1/4-inch of compost resulted in forage production that was higher than areas where no amendment was applied and areas that were treated with a chemical fertilizer.
“The biggest impact was under drought shelters,” said Shaw, referring to PVC frames that were covered with plastic during rain events to understand the impact of the treatment under dry conditions. “In the drought plots, the areas where compost was applied are staying green longer.”
A defining research tool at SFREC is a dataset that includes information on monthly rainfall and forage production going back 40 years.
A review of the data shows surprising variations and correlations at the center, where forage production averages 3,000 pounds per acre, but ranges from about 1,000 pounds per acre in 1987, to over 5,000 pounds per acre in 2018, when there was so much growth, “we didn't have enough animals to graze,” James said.
The dataset paints a spectrum of the variation that ranchers across the state must navigate to manage their livestock and rangeland in a way that is profitable and ecologically sound. Research at the Sierra Foothill REC offers invaluable information to help them better understand the ecosystem and make informed decisions.
