Rancher wisdom can be improved with science
When California was part of the Wild West, it took a certain amount of guesswork to move cattle from their home range to summer pastures while making sure sufficient forage was left behind to hold the cattle over till fall rainfall spurred new growth.
“Ranchers eyeballed it,” said Theresa Becchetti, UC Cooperative Extension livestock and natural resources advisor. “In time, second-, third-, and fourth-generation ranchers got pretty good at deciding, but UC Cooperative Extension introduced a more scientific approach.”
In the spring of 1936, the USDA Forest Services began measuring ungrazed forage at the San Joaquin Experimental Range in Madera County. The project continues today as a joint effort of UC Cooperative Extension and the USDA Natural Resources Conservation Service.
Sixteen years later, just after the UC Hopland Research and Extension Center was established on Mendocino County rangeland in 1951, another study began; and in the early 1980s, scientists at the UC Sierra Foothills Research and Extension Center in Browns Valley commenced a similar long-term study.
As scientists learned of the multiple factors impacting forage production across the Coast Range and Sierra Nevada foothills, some 70 research sites were identified – most on private land - and consistently monitored. The results show that there is much more to understanding forage growth than looking at a rain gauge.

While high annual rainfall usually results in high forage production and low annual rainfall generally results in low annual production, there are exceptions. It all depends on the timing of the rainfall.
During the devastating drought of 2011-2016, Becchetti noticed forage production didn't mirror the drought damage to state water resources and mountain forests.
“It was interesting,” said Becchetti. “In a lot of my plots, forage would be close to normal. We got rain when the soil was warming up. If we get rain in the late fall or winter, there is no grass production because it's too cool. If rains come when the temperatures warmed up, the grass takes off.”
The expected variation from climate change is another factor that encourages UCCE scientists to conduct routine forage monitoring.
“When I started 11 years ago, we had some good production years; we had poor years, a couple of normal years,” Becchetti said. “Monitoring is giving us a better snapshot that all of us can use to see the impact of climate change on forage production.”
To develop an accurate picture of forage growth, the research locations are fenced or caged to keep out grazing animals. Grass and forbs within one square foot of the exclosure is clipped to the ground. The vegetation is dried, weighed and the figures logged in a database.
Long-term production data are particularly valuable for the three research stations because daily weather data that are also collected there can be used to determine the effects of rainfall and temperature on annual forage productivity.
Year-to-year variability at the Hopland research site ranged from 900 pounds of forage per acre in the poorest year, up to a 3,500 pounds per acre bounty when conditions were just right. Average annual production at Hopland is 2,399 pounds per acre. At the Sierra Foothill Research and Extension Center, annual forage ranged from a low of 1,071 per acre up to 4,696 pounds per acre. The average annual production there is 2,971 per acre.
“There is no way we could represent the exact forage production across the state, but this does allow us to come up with a percent either below or above normal for a particular area,” Becchetti said.
The monitoring research conducted by UCCE scientists are important to provide guidance to county agricultural commissioners and local Farm Service Agencies.
“If you think about it, so many of our ag commodities are based on weight or volume,” said Scott Oneto, UCCE rangeland and natural resources advisor in El Dorado, Tuolumne, Calaveras and Amador counties, where annual monitoring has been conducted for 25 years. “But annual rangelands are so different when it comes to figuring out whether a given year is average, above average or below average. And when crop insurance is involved, it makes it very difficult for ag commissioners to declare a loss if they don't know what the loss is or if there even was one.”
Becchetti, along with 14 current and former UCCE colleagues, wrote a 12-page review of UCCE's ongoing range forage production study, which includes average production for many of the study sites. ANR Publication 8018 is available for free download from the UC ANR publication catalog.
UC ANR, CropMobster partner to share inspiring stories of ag innovation and food system champions
CropMobster TV's Season 2 takes viewers on a journey throug every county of California, meeting food and ag leaders and seeing how they carve out their livelihoods while feeding their communities.
Most consumers' first encounter with their food is in a grocery store or on a plate served in a restaurant, and they give little thought to how the food got there.
As a sponsor of CropMobster TV Season 2, UC Agriculture and Natural Resources is pleased to help introduce some of the Californians who toil behind the scenes to provide consumers the delicious and nutritious food we eat.
Nicky Bobby chats with farmers, people at nonprofit organizations that work to reduce food waste and hunger, scientists, land managers who steward our natural resources and business owners.
“Everybody's into food, but all too often people don't make the connection between food and agriculture,” said Glenda Humiston, University of California vice president for agriculture and natural resources. “When you talk about agriculture, people think of two jobs – farmer and farmworker. There are thousands of jobs in the agricultural ecosystem.
“UC ANR is happy to support CropMobster in telling the stories of the men and women who supply us with safe and abundant food, the challenges that they face and the efforts being made to make the food system even better.”
CropMobster TV is a nonprofit storytelling and video project by CropMobster in collaboration with Food Tank and many other individual and organizational supporters to highlight the crucial work of everyday heroes working to feed their communities.
“Sponsorship and support from UC ANR, which does agricultural research and outreach in every California county, is helping us connect with communities throughout the state,” said Papadopoulos, CropMobster CEO. “We are also grateful for Food Tank and so many other individuals and organizations who are pitching in.”
“This is such a unique, energetic and needed effort to engage our populace on food and agriculture issues,” said Danielle Nierenberg, Food Tank president. “We are thrilled to partner with CropMobster and UC ANR and hope to see the CropMobster vision grow and spread!”

Direct-marketing farms have double the regional impact
Sacramento-area farmers and ranchers who sell their products directly to consumers generate twice as much regional economic impact per dollar of output as do area food producers who don't engage in direct marketing, reports a UC Davis agricultural economist and a team of UC Cooperative Extension researchers.
The newly released study of the four Sacramento region counties of El Dorado, Placer, Sacramento and Yolo found that direct-marketing food producers had a regional output multiplier of 1.86 compared to just 1.42 for producers not involved in direct marketing.
Direct-marketing channels include farmers markets, roadside farm stands and community-supported agriculture programs that provide consumers with regular deliveries of farm products.
“The direct marketers make up a relatively small part of the Sacramento region's agricultural sector, but this study demonstrates that these food producers generate both economic and qualitative benefits for the region,” said study leader Shermain Hardesty, a UC Cooperative Extension specialist in the UC Davis Department of Agricultural and Resource Economics.
“It's important that the economic contributions of direct-marketing farmers and ranchers be taken into consideration so that regional policies can be enhanced to support and nurture the growth of these food producers,” Hardesty said.
The regional economic impacts identified in the study are threefold: revenue received directly by the agricultural producer; a ripple effect when the food producer purchases inputs in the region; and a secondary ripple when the producer and the suppliers of goods and services to the producer, in turn, spend more money in the region on household goods and services.
The report, along with separate economic impact reports specifically for El Dorado, Placer and Yolo counties, is available online.
Sacramento region direct marketers
In the four-county Sacramento region, direct-marketing food producers are a relatively small segment of the total agricultural sector, accounting for 19 percent of the region's farms and only 4 percent of its agricultural production.
The direct-marketing farm operations tend to be smaller and more labor-intensive, and source more of their inputs locally than do nondirect-marketing operations in the area.
The new study was based on economic information gathered from 88 local farmers and ranchers, including 31 vegetable farmers, 48 orchard or vineyard growers and nine livestock producers, each of whom generated at least $1,000 in annual sales from marketing directly to consumers.
After the data were collected, they were incorporated into an economic modeling program to estimate the economic impacts of producers engaged in direct marketing.
Study highlights
Other findings from the report include:
• Sacramento region direct-market producers averaged just $164,631 in one year of sales compared to $568,105 for those not engaged in direct marketing.
• Seventy-three percent of the direct marketers also sold through wholesale channels.
• Overall, the direct-market producers generated 44 percent of their total revenues through direct-marketing channels, 55 percent through wholesale channels and 1 percent through commodity markets.
• For every $1 million of output, the direct-market producers generated a total of 31.8 jobs in the Sacramento region while the nondirect-market producers generated only 10.5 jobs.
• Direct marketers purchased 89 percent of their inputs within the region while the nondirect-market producers purchased 45 percent of their inputs in the region. This local sourcing of inputs was the primary factor responsible for the direct-market producers having a greater economic impact on the region than nondirect-market producers.
Collaborators and funding
Hardesty collaborated on the study with Libby Christensen, Erin McGuire and Gail Feenstra, all of UC Davis; and Chuck Ingels, Jim Muck, Julia Boorinakis-Harper, Cindy Fake and Scott Oneto, all with the UC Cooperative Extension.
Funding for the study was provided by the University of California Division of Agriculture and Natural Resources Competitive Grants Program.
Beautiful but ecologically harmful shrubs get a foothold in California forests
Scotch, Spanish and French broom were introduced from Europe in the mid-1800s as lovely, easy-to-grow garden accents and land stabilizers, but they have become aggressive invaders threatening native plants and increasing fire hazards.
“These brooms crowd out our native flora and form large, dense stands of just broom,” said Scott Oneto, UC Cooperative Extension advisor in the Central Sierra. “It’s also displacing the birds and animals that would live in this environment with native plants.”
The characteristics of invasive brooms cause several problems. The plants grow large and upright, developing thick trunks at the base. After its relatively short life span - typically 7 to 8 years, 15 at the most – they die and become tinder-dry woody skeletons that can burn high and hot.
The brooms are also a member of the legume family. Legumes are unique in the plant world. They have evolved a symbiotic relationship with bacteria that live on their roots. The bacteria are able to pull nitrogen from the atmosphere and deposit it into the soil, where it feeds the plant.
“These soils are naturally very low in nitrogen,” Oneto said. “Our native plants thrive in low-nitrogen soils. Large populations of broom are changing the soil chemistry so even after they are removed, the area is no longer ideal for our native vegetation.”
Large stands of broom are also a significant concern for rangeland managers. Cows don’t like the taste; only goats will eat it. When the plant is grazed off or cut back, it readily re-sprouts from the crown. The plant’s spread is bolstered by its intriguing ability to scatter seeds widely. Brooms grow seed pods that are naturally spring loaded. When the seeds are ready for dispersal, they fling from the pod with the force of a tiny explosion.
In collaboration with the non-profit California Invasive Plant Council, which received a grant from the Sierra Nevada Conservancy, Oneto is working to eradicate broom from a particularly sensitive location. Highway 120, for many the “gateway to Yosemite,” has populations of French and Spanish broom.
“We’ve started by mapping the broom along Highway 120 and plan to eliminate the population to prevent it from moving further into the forest and eventually into Yosemite National Park,” Oneto said.
The grant is providing the funding for environmental and regulatory compliance so that control measures can be implemented.
“Once the regulatory compliance is complete, the project will be shovel-ready and we can begin treatment,” Oneto said.
“If broom is growing wild or as an ornamental on your property, we suggest you remove it and replace it with a non-invasive plant,” said Rebecca Miller-Cripps, natural resources program representative with UCCE Central Sierra. For example, forsythia produces yellow flowers and a shrub of about the same size and shape as brooms, but isn’t invasive, she said.
