UC Davis report suggests ways to build resilience
The University of California, Davis, Food Systems Lab has released a white paper showing the need to support California's small and mid-scale meat suppliers and processors in order to build a more resilient meat supply chain. It describes how the meat supply chain and rural economies could benefit from regulatory changes and more collaboration among producers and other stakeholders in the system.
The pandemic shut down meat processing plants in 2020, as did recent ransomware attacks on JBS, the nation's largest meat supplier. Report authors said this highlights the need to support small- and mid-scale suppliers.
“COVID and the ransomware attacks put a spotlight on how the concentration of the meat supply chain increased vulnerability in the food system,” said report co-author Tom Tomich, founder of the UC Davis Food Systems Lab and distinguished professor in the Department of Environmental Science and Policy. “We need to level the playing field so small- and mid-scale farms have an easier way to bring their product to market.”
The report says the lack of access to slaughter facilities, limited capacity of cut and wrap facilities, and concentration of marketing channels create conditions in which small- and mid-scale farms and ranches struggle to stay in business.
“These challenges are exacerbated by policies that tilt the playing field against small operators. Fortunately, new state and national legislation and programs are developing that could increase resilience in our food systems,” says Michael R. Dimock, Roots of Change program director and lead author for the report. “We need cities and counties to help fix the problems because local land use policies often impede development of resilient supply chains.”
Lack of access and limited capacity
Smaller ranchers in California have limited access to slaughter and processing facilities. In the last 50 years, California has lost half of its federally inspected meat processing plants, and the remaining facilities are unable to meet demand. Many of the 46 USDA-certified slaughter plants operating in California are closed to smaller producers.
“This means that smaller ranchers must drive hundreds of miles to reach a facility or have to wait months due to limited capacity,” said Tomich.
The report said a combination of federal, state and private investments could provide a broader geographic distribution of plants of differing scales. It also suggests expanding mobile, on-farm slaughter operations for sheep, goats and hogs, similar to those for beef.
Regulatory barriers and opportunities
Complex inspection requirements and other regulatory barriers make it difficult for small- and mid-scale producers to compete with big suppliers. The report suggests California create its own meat inspection program equivalent to the federal program to serve smaller ranchers. Prioritizing public procurement of local, high-value meat would also help expand market access for smaller producers.
Broader benefits of smaller operators
The report notes other beneficial roles of small- and mid-scale livestock operations, apart from the potential to increase resilience in our food system. Livestock grazing is a cheap and effective way to reduce wildfire risk. Supporting local meat processing also helps rural economies and creates community-based jobs.
The report was based on 27 interviews with people representing a wide spectrum of activities and points of view within the meat supply chain throughout the state. Authors are Courtney Riggle, Allan Hollander, Patrick Huber and Thomas Tomich of the UC Davis Food Systems Lab, and Michael R. Dimock with Roots of Change.

Well-managed grazing can control non-native plants and maintain habitat and ecosystems to support a variety of species
Research recently published in the journal Sustainability documents a role for livestock grazing to support the conservation of imperiled plant and animal species in California.
Livestock grazing occurs in every county except San Francisco and is the single greatest land use in California. Grazing livestock, primarily beef cattle, often share lands with threatened and endangered species. California has more federally listed threatened and endangered species (287 plants and animals) than any other state in the continental US. While this is a result of our state's varied climate, soils and topography, the threat to diversity is predominantly from habitat loss due to land use change. Housing and urban development, solar and wind farms, cultivated agriculture, and public works projects such as reservoirs, roads and high-speed rail all result in habitat loss for some native species, many of which are threatened or endangered. Alternatively, maintaining ranching, or managed grazing for beef cattle production, can support the conservation of many threatened and endangered species in California.
A review of United States Fish and Wildlife Service (USFWS) listing documents for threatened and endangered species in California provided an opportunity to understand the relationship between livestock grazing and species conservation. Based on USFWS documents, 51%, or 143, of the federally listed animal and plant species are found in habitats with grazing. Livestock grazing is a stated threat to 73% (104) of the species sharing habitat with livestock, but 59% (85) of the species are said to be positively influenced, with considerable overlap between species both threatened and benefitting from grazing. The fact that USFWS identifies grazing as both a threat and a benefit to many species indicates that how grazing is done matters.
While species may be negatively impacted by grazing that is excessive or unmanaged, managed grazing can control vegetation and maintain habitat structure and ecosystem function to support a variety of species. Controlling non-native species, mostly non-native annual plants, is the most frequent reason that grazing benefits both federally listed flowering plant and animal species in California. In fact, 89% of species positively impacted by livestock grazing benefit from control of non-native species. For example, controlling non-native annual grasses favors native forb or broad-leaf plant populations that support the conservation of 10 different butterfly species and one moth species which rely on forbs for nectar and larvae food.
In addition to controlling non-native plants, grazing benefits some listed species by controlling vegetation, including thatch or dead plants that alter habitat. In the grasslands and shrublands of the San Joaquin Valley, maintaining habitat with sparse vegetation supports a variety of listed species, including the Kern mallow plant (Eremalche parryi ssp. Kernesis), the blunt-nosed leopard lizard (Gambelia silus), the giant kangaroo rat (Diposdomys ingens), and the San Joaquin kit fox (Vulpes macrotis). For the small ground-dwelling animals, annual grass and thatch can create an impenetrable thicket. For the larger native animals like the San Joaquin kit fox, taller, dense vegetation can obscure the visibility of predators. Habitat with sparse vegetation is also necessary for listed plant and animal species in coastal grasslands, including the Santa Cruz tarplant (Holocarpha macradenia) and Ohlone tiger beetle (Cicindela ohlone).
Some species (plants, insects and a reptile) benefit from grazing that controls vegetation associated with air pollution. The USFWS cites research that shows air pollution, specifically dry atmospheric nitrogen deposition, creates a fertilizer load that alters plant communities and habitat, and livestock grazing can restore or maintain habitat by removing excess vegetation and nitrogen. The control of vegetation through grazing is also associated with maintaining grasslands by preventing succession or invasion by brush to benefit some animal and plant species. For listed plants like the Western Lily (Lilium occidentale) that are threatened by loss of grassland, the USFWS has stated that the benefits of grazing seem to outweigh the potential threat to these plants being grazed or trampled.
Within aquatic habitats, species benefitting from grazing, which includes flowering plants, amphibians and invertebrates, are primarily found in temporary or vernal pools, where livestock help maintain an adequate inundation period. Listing documents for species in temporary pools cite research that describes increased grass cover in and around ungrazed vernal pools leading to increased evapotranspiration and decreased pond duration. Other benefits stated for listed species in aquatic habitats include two animal species that benefit from the presence and maintenance of stock ponds associated with livestock grazing.
This review of the USFWS listings documents concludes that many federally listed species in California are conservation reliant, requiring continued interventions to support their lifecycle or maintenance of habitat, and that sharing land with livestock grazing is an important conservation strategy. Species benefiting from grazing are often threatened by the loss or cessation for grazing. Most, if not all, ecosystems on the planet have been altered by land use and other anthropogenic effects. Threats to biodiversity stemming from pervasive non-native species, climate change, and the disruption of essential ecosystem processes and disturbance regimes are not typically overcome simply by preserving land, improving regulatory protections, and removing threats. Livestock grazing is perhaps the only ongoing land use that can be feasibly manipulated to manage vegetation and habitats at the landscape scale.

Improved soil health, increased profitability, and reduced spread of wildfire are among the many benefits that arise from keeping livestock on the landscape. Efforts are underway in California and South Dakota to connect landowners with livestock managers for their mutual benefit.
Farmers can increase the organic matter in their soil and reduce their fertilizer costs by allowing livestock to graze crop residue or cover crops on their land.
Nick Jorgensen, CEO of Jorgensen Land and Cattle in Ideal, SD, said that grazing every acre allows his operation to increase soil organic matter by up to 0.75% per year and cut fertilizer costs by $50 per acre with no yield loss.
Livestock managers can rest their pastures and reduce their feed costs by seeking out crop residue, cover crops and additional pasture or rangeland for their livestock to graze.
Jorgensen said that grazing cattle on all crop and cover crop acres cuts his feed and manure management costs by up to $2 per head per day.
Grazing livestock is also a cost-effective way to reduce the accumulation of fire fuels on the landscape, helping to slow the spread of wildfires. This can be especially important for land that is too steep, rocky or remote for mowing or chemical treatment.
“I've noticed on several fires, including extreme fires, the fence lines where the fire just stopped. And the one variable, the one difference, was grazing,” CAL FIRE Battalion Chief Marshall Turbeville said.
As this year has proven, fire is a serious risk to California landowners. That's one reason University of California Cooperative Extension has launched Match.Graze. It's a map-based website designed to help livestock owners find pasture, rangeland, cover crops or crop residue available for grazing and help landowners find cattle, sheep, goats and other livestock to graze their land.
“Every property is different and requires thoughtful consideration of how it should best be grazed,” said Stephanie Larson, director of UCCE in Sonoma County, UCCE livestock and range management advisor and co-creator of the livestock-land matchmaking service. “UC Cooperative Extension is here to serve. Put Match.Graze to work, and let's prevent catastrophic fire while helping landowners and agriculture.”
California landowners and livestock managers can visit MatchGraze.com, set up a free account, create a pin on the map and find a grazing partner.
The California website is based on the South Dakota Grazing Exchange, the original site launched by the South Dakota Soil Health Coalition with work supported by Natural Resources Conservation Service, U.S. Department of Agriculture.
Many farms in South Dakota have moved away from livestock to focus on row crops. However, increased diversity and incorporating livestock are two key principles for good soil health management.
At www.sdgrazingexchange.com farmers can find livestock to graze their crop residue or cover crops in order to capture the soil health benefits for their cropland without having to own livestock. Similarly, ranchers can give their pastures and rangeland a rest and reduce their feed costs by finding farmers with cropland to graze.
The Match.Graze and SD Grazing Exchange websites are not limited to California and South Dakota. Users from anywhere in the nation can create accounts on either website and advertise their land and livestock. The more people who use the websites, the better resources they will become.
When landowners partner with ranchers to keep livestock on the landscape, everyone wins, so the SDSHC will work to help other states create Grazing Exchange websites and connect to the maps and users of Match.Graze and SD Grazing Exchange. For more information, contact Cindy Zenk, SDSHC coordinator, at (605) 280-4190 or firstname.lastname@example.org.
Matchmaking grazing animals with grass and rangelands
Professional grazing of overgrown rangelands, pastures and parcels is proven to reduce the spread of dangerous and costly wildfires.
Do you have land but no livestock and feel concerned about fire fuels on your property? Or are you a livestock owner that can provide a grazing service and/or need land and forage for your animals? Match.Graze can help.
Match.Graze is a free online platform connecting landowners statewide who want grazing animals to livestock owners with animals that can provide vegetation management services, created by UC Cooperative Extension.
From small semi-rural communities to large open spaces, grazing can provide an affordable solution to the inevitable accumulation of fire fuels. Grazing can be more cost-effective for reducing fuels on landscapes that are too steep, rocky or remote for mowing or chemical treatment, or in the wildland-urban interface where burning is not an option.
“I've noticed on several fires, including extreme fires, the fence lines where the fire just stopped. And the one variable, the one difference, was grazing,” said Marshall Turbeville, CAL FIRE battalion chief.
Cattle, sheep, goats and other grazing animals all have different roles to play in grazing for fire fuel reduction. If you want to use livestock to help reduce fire risk in your area, visit MatchGraze.com.

Cattle can help reduce wildfire danger by grazing on fine fuels in rangeland and forest landscapes, reported Sierra Dawn McClain in Capital Press. The article also appeared in the Blue Mountain Eagle, the Westerner and the East Oregonian.
The article cited the preliminary results of research by UC Cooperative Extension that show that cattle consumed approximately 12.4 billion pounds of forage across California in 2017. The researchers believe the cattle could do more.
Many grazable acres aren't grazed, said Sheila Barry, UCCE livestock and natural resources advisor in Santa Clara, San Mateo, Alameda and Contra Costa counties. According to the Capital Press article, Barry said the public doesn't always recognize the benefits of grazing; they see short grass and cow patties. Cattle's role in preventing wildfires is often overlooked.
Devii Rao, UCCE livestock and natural resources advisor for San Benito, Monterey and Santa Cruz counties and the study's lead, said ranchers should target grazing around homes, infrastructure, roadsides and at the wildland-urban interface.
“There are so many things we can do better. Cattle grazing is really important to fire safety, and it's time we have more conversations about it,” Rao said.
