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.
“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.”

As previously mentioned in the September 2018 issue of the Farm Bureau newsletter, the frequency, intensity, and size of wildfires in northern California have increased. This trend is alarming given that California's fire season is expected to become longer and start earlier. The fire season started in early June this year as Sonoma County experienced smoke from Sand Fire in Yolo County. To mitigate future fire, the County of Sonoma has adopted a new hazardous vegetation abatement ordinance which mandates that parcels of 5 acres or less must maintain defensible space around all buildings/structures and remove all vegetation that poses a fire risk. As policymakers in our communities and across the state continue to explore initiatives to prevent wildfire, the agricultural community can demonstrate real impacts in reducing fire fuel through managing existing vegetation on our working landscapes - forest and rangelands. We need to educate the public on the importance of managing these valuable landscapes using a multitude of tools, especially grazing. The extent to which the public understands fire risks and accepts the adoption of all potential tools for forest and rangeland health will increase the likelihood of potential collaborative management strategies imperative to community resiliency.
Grazing is a cost-effective vegetation management alternative that works best in cases where other options are impractical and financially ineffective. Specifically, targeted grazing can be more cost-effective on landscapes that are too steep, rocky, or remote for conventional vegetation management (like mowing or chemical treatment), or in the urban-wildland interface where burning is not an option. Targeted grazing is the application of a specific kind of livestock at a determined season, duration, and intensity to accomplish defined vegetation or landscape goals. This concept has been around for decades and has taken many names, including prescribed grazing and managed herbivory. The major difference between good grazing management and targeted grazing is that targeted grazing refocuses outputs of grazing from livestock production to vegetation and landscape enhancement. The concept of a target requires that one has a clear image on which to focus and then aims something (i.e., an arrow) at the target to accomplish the desired outcome. In the case of targeted grazing, the land manager must have a clear vision of the desired plant community and landscape, and the livestock manager must have the skill to aim livestock at the target to accomplish land management goals.
As mentioned in the June 2019 Farm Bureau newsletter (Quackenbush), sheep grazing is being applied on lands throughout the county to help reduce fire danger. Targeted grazing is a very different business model than simply grazing for livestock production. Effective targeted grazing focuses on impacting target vegetation at exactly the right time for specific landscape or vegetation goals. Traditional livestock production, on the other hand, focuses on putting weight on animals or increasing reproductive success. Traditional livestock operations generate income from the sale of animals and animal products; these operations focus on body condition and the nutritional status of the animals at specific production stages. Targeted grazers generate income from vegetation management services; these operations may accept a drop in body condition or reproductive success to achieve desired impacts to low-quality forage as long as this service is paid for. Both models can reduce fire fuels; no one model is better than the other.
Last month, UC Cooperative Extension and SRJC Agriculture and Natural Resources Department offered a grazing school at Shone Farm. Landowners and targeted grazers learned how to implement targeted grazing on local working landscapes. Participants gained knowledge on how to design a grazing program on their own managed lands or if they decided not to own animals, how to use this knowledge when hiring a targeted grazer. A neighborhood grazing partnership was created at the school along with new opportunities for targeted grazers.
Additionally, UC Cooperative Extension (UCCE) Sonoma/Marin, is creating a “Match.Graze” system which connects landowners, who have no animals, to targeted grazers, those that can bring their animals on property to perform vegetation management service. If your parcel (s) is/are greater than 50 acres, this system will be a great resource. While it is more cost-effective for target grazers to grazer larger parcels, those with smaller parcels in neighborhoods or communities can join together to have multiple parcels of varying sizes in the same geographic area receive vegetation management by the same grazer. If you want more information about the use of grazing, how to set resource goals for your rangelands, or help to find a grazer for your parcel, call the UCCE office at 707-565-2621 or complete this survey to help UCCE better meet your desire to manage vegetation to prevent future fires in Sonoma and Marin Counties. The survey can be found at www.ucanr.edu/rangeland.

Vernal pools exist in areas of a grassland where there is an isolated area of compacted clay or bedrock. This is because the water cannot penetrate it and therefore, stays on the surface instead of absorbing into the soil. Depending on their size and amount of rainfall, they may fill and dry up many times within a season, or may not fill at all in a drought. Many species of wildlife, including birds and amphibians, depend on these pools. They are a cache of fresh water and food and, for some, a good place to lay their eggs because they are safe from predation by fish.
For the first time in four years, US Fish and Wildlife Service (FWS) opened grazing permits for several properties in the Santa Rosa plains, allowing grazing. Grazing was returned to these properties because its removal caused vegetation to over grow, reducing habitat for the endangered species present. Not having this grazing “disturbance” resulted in a species loss; the very species that were to be protected. Two examples of grazing benefits are listed below.
California Tiger Salamander
Managed livestock grazing is thought to benefit the habitat for California tiger salamander (Ambystoma californiense) (Fig 1). Some Bay Area populations of these salamanders depend on ground squirrel burrows for refuge sites. Livestock grazing keeps vegetation low, making the grasslands more suitable for California ground squirrels (USFWS 2003). Salamanders that inhabit vernal pools may also benefit from grazing. These ephemeral pools are wet only during the winter/spring rainy season, and too much vegetation in and around their edges can cause drying pools to lose depth too quickly. Because it reduces this vegetation, grazing can keep the pools wet longer, giving salamander larvae more time to grow up (USFWS 2004).
Opportunities for Native Plants
Grazing of non-native vegetation is essential to create opportunities for many native grassland plants. For example, there is only a single remaining natural population of the federally-endangered Sonoma spineflower (Chorizanthe valida) (Fig 2) and it declined dramatically after livestock was removed from its habitat area (Davis and Sherman 1992). Similarly, populations of the federally-endangered Contra Costa goldfields (Lasthenia conjugans) and Santa Cruz tarplant (Holocarpha macradenia) plummeted and died out when grazing was removed from their habitats (USFWS 2005; Hayes 1998).
Nowadays, 90% of the US's vernal pools have disappeared due to human encroachment and land conversion. Like the rangelands they exist on, they can be beautiful and vital places if properly managed! With the arrival of the Spanish missionaries, Sonoma County's grasslands changed dramatically. They became dominated by non-native annual plants, mostly from the grasslands of the Mediterranean Basin. Despite the general replacement of native plants by these non-natives, enough native species have survived to prompt global recognition of our grasslands as hot spots of biodiversity.
Because livestock grazing (primarily by cattle) can effectively reduce the biomass, height, and thatch accumulation produced by non-native annual plants, it has become an essential tool for managing our local grasslands. Grazing has been shown to be a benefit by
reducing the risk of a catastrophic wildfire, maintaining and enhancing habitat for many native grassland plants and animals,
and maintaining the open character of our iconic grasslands and oak savannas.
Ranchers should be encouraged to continue their sustainable livestock production practices and their long history of good stewardship. In addition, they should be compensated for implementing other conservation services on rangelands./h2>/h2>/table>

The University of California Cooperative Extension recognized rangelands and their importance in Sonoma County, creating the “Ecosystem Services Interpretative Signage” to increase awareness and knowledge of park visitors, mangers and decisions makers of working rangelands and the ecosystem services. Rangelands are also referred to as working landscapes, are locally managed and provide essential biological, scenic, economic, and recreational values locally and throughout the world. Working landscapes are threatened in many areas by development, conversion to
Beyond the obvious benefits of beef cattle grazing such as food production, grazing can benefit individual plant and animal species, can help manage fire hazards, and, in the absence of natural disturbance regimes, help maintain Sonoma County's landscape structure. Beef cattle not only provide beef as food, they are also used as grazing tools, keeping weed or shrub invasion at bay, enhancing wildflower displays, or maintaining a low grassland canopy height to allow visibility, foraging, and movement of small mammals such as voles and ground squirrels. Rangelands not grazed or otherwise managed, especially where they abut or intergrade with shrublands, will become shrub invaded, which converts grasslands to coastal scrub. As well as increasing fire hazards, this conversion results in loss of coastal grasslands and; thus, loss of the species that occupy them. Fire and livestock grazing are the two main tools we can use to maintain grassland ecosystems. In Sonoma County, fire has become more difficult to use, livestock grazing is the most common and practical option. Maintaining rangelands has several benefits associated with water, including increasing water infiltration and increasing vernal pool inundation period for fairy shrimp and the California tiger salamander. In addition to ecosystems services associated with water, livestock grazing can also improve habitat for native annual forbs & grassland birds, control invasive weeds, reduce fire hazard, etc.
