Managing the distribution of grazing livestock is critical to promoting sustainable ranching practice and sustainable ecosystems. Livestock are naturally selective in their foraging habits and do not graze pastures uniformly. In response, ranchers have long implemented practices intended to improve distribution on rangeland, such as installing off-stream water or cross-fencing. These practices, however, can be impractical or uneconomical at large spatial scales across rugged landscapes. As an alternative, stockmanship—or, the skillful handling of livestock in a safe, efficient, and low-stress manner—is another tool that can help address concerns over uneven utilization. More specifically, low-stress herding can be used to strategically place livestock within a pasture to ensure uniform utilization of forage and to avoid excessive use of sensitive resources.
Our project aims to establish the efficacy and practicality of using stockmanship and low-stress herding in a production setting. Using GPS collaring of cattle and transect monitoring, we expect to show that these practices can both improve ranchers’ profitability (by increasing the number of livestock per unit area) and positively support multiple ecosystem services (protecting water quality and sensitive riparian habitats, improving vegetation for wildlife habitat, and decreasing the risk of catastrophic wildfires). Additionally, on-ranch field days throughout the course of the project will introduce the basics of low-stress herding to regional producers and share ongoing, preliminary results. Our outreach is designed to maximize frequent interaction between project leaders and regional producers and to facilitate regular discussion. This project approach blends science and practice in what we expect to be an innovative method to transmit stockmanship and low-stress herding to producers in our region.
- Convene a two-day short course—bringing together academics, industry professionals, and private consultants—to introduce the principles and practices of herding and stockmanship to ranchers in the region.
- Establish experimental control and treatment pastures on a working ranch in Ventura County to measure the effectiveness of herding to improve livestock distribution across three growing seasons, beginning Fall 2018.
- Develop a set of practical metrics against which to measure the success and efficacy of applied practices.
- Hold at least two field days (Years 2 and 3) to demonstrate and extend the use of herding to improve livestock distribution to ranchers in the region.
- Publish materials (bulletins, online articles, and videos) to be distributed statewide, which would present the results from our experimental treatments, provide cost-analysis of the practice, and offer recommendations.
We experienced some setbacks early in our grant execution process that we have since recovered from. An early challenge was that fire and drought meant that Mike Williams could not renew the lease on the ranch in Ventura County (Canada Larga) on which we planned to conduct our Western SARE project. Mike ranches on another 12,000-acre property in Los Angeles County and so we chose to move our project location there. The property in LA County (Ritter Ranch) has similar topography and vegetation as does Canada Larga, however there were far fewer internal, cross fences separating pastures. With fewer pastures, we needed to reconsider our study design. The Latin-square design we proposed initially required at least two large pastures with similar characteristics; Ritter Ranch really did not allow for this approach. After consulting with experts at UC Davis and Chico State, we settled on a different design: Year 1 would become our “control.” GPS tracking collars would be administered to cows on the ranch and field data would be collected but we would administer noherding treatments. Years 2 and 3 would be our “treatment” years: we would continue to collar cows and collect field data, and Mike would begin administering the herding treatment.
We spent April and May 2018 gathering supplies and building the GPS collars. Collars were applied to thirteen mother cows in late June 2018, which represents the beginning of data collection on the project. Cows will be managed from June 2018-June 2019 much as they have been in previous years. In July 2019, we expect to begin our herding treatment, which will consist of bunching and placing the cows every 3-5 days. In December 2018 (end of dry season) we collected fecal pat data at over sixty transects on the ranch that we stratified in areas of heavy and light use. We expect to continue that monitoring every six months.
We are planning on having our first workshop for ranchers in July 2019. The workshop will last two days and will gather experts, academics, and ranchers to showcase our SARE project and have them share techniques and experiences.
We currently have no results to share. Data collection is ongoing. We anticipate having our first results to report in December 2019.
Educational & Outreach Activities
Year 1 of our project has consisted entirely of getting our experimental research designed and initiated. Year 2 will focus more on outreach and extension. We have plans to hold a 2-day work workshop for ranchers in July 2019 and to publish a number of extension materials related to the project.
Our only effort at outreach thus far has been a poster at the California Cattleman’s Association in November 2018. The poster was included in the poster session at the conference center, where over 300 ranchers were in attendance.
