On November 5^th, 2013, SFREC will bring together UC researchers, land managers, producers and conservation professionals from across the state to explore some of the latest research findings and management strategies on two of the most serious rangeland weeds, medusahead and barb goatgrass. Estimates indicted these invasive species may decrease forage quality and production by up to 70 percent. Additionally, these plants increase the incidence of eye problems, such as pink eye in beef cattle.  Intermountain species like medusahead create significant fuel accumulation - increasing the frequency of dangerous wildfires that destroy both livestock feed and critical wildlife habitat.

The University of California, in cooperation with producers, land managers, and agency partners, have made great strides in researching the ecology and management of these species. This forum takes a timely approach toward synthesizing outcomes of these diverse efforts.  A number of treatments, such as grazing, herbicide application, burning, and seeding, have shown promising results. However, there are risks and challenges that remain when trying to apply these efforts in unique rangeland environments at large scales. Discovering economically compatible techniques that can be molded to meet the financial constraints of producers and other land managers is a crucial investigation. A major aim of this forum is to enhance further discussion and progression towards how we might tailor future research and management efforts to address this challenge.  This free forum is open to everyone. Please pre-register on the SFREC website to receive a detailed agenda and information about the day.

Water - the focus of countless issues, headlines, and studies - is arguably a more precious resource than gold.

Dependence on water application ranges far and wide in today's thirsty society – from drinking to sanitation to agriculture. This valuable resource needs to be managed efficiently to ensure each drop is spread the furthest.

Individuals involved with the University of California's Division of Agriculture and Natural Resources are actively evaluating management practices to ensure and develop water-wise irrigation methods.  At the Sierra Foothill Research and Extension Center, many research projects have focused on water quality, runoff, and irrigation efficiency. A current project led by Livestock Farm Advisor Larry Forero monitors surface runoff and soil moisture content in flood irrigated pastures at SFREC.

The goal of this project is to ultimately estimate the efficiency of a “wild flood” surface irrigation system so practical opportunities for reducing irrigation water use can be suggested without impacting production. Gary Childers, staff member and key irrigator at SFREC for over 30 years, frequently collects data from watermark sensors located at various points across two pastures. The sensors are at depths of 6”, 12”, and 24”. A key component of this project compares the amount of water delivered to the site with the amount of tailwater leaving the pasture. All irrigation water at SFREC is received via pipeline or channeled through ditches by the Brown's Valley Irrigation District, fed from Collins Lake.

Although over 100 miners inches (2.5 cf/s) are purchased annually by SFREC, sustainable water utilization methods are executed. “Nearly every application of irrigation water is used at least twice, but as many as four times – just on this property. Once the water leaves, additional uses occur but are unknown,” explained Childers.

Gold may be in high demand - with the current value exceeding $1320 per ounce - but once water becomes scarce, it is truly priceless. By taking the initiative to research innovative water management practices and develop a better understanding of sustainable irrigation methods, SFREC and the entire UCANR division are enabling water availability and conservation for the future.

Head, heart, hands, and health. These four words establish the foundation upon which the nation's largest youth development organization has grown, thrived, and continues to develop inspiring community members.

Last week the Sierra Foothill Research and Extension Center was fortunate to host a group of high school-aged 4-H students and adults for a short tour of our facilities. About half of the group was visiting from Wisconsin through an exchange program and noticed the significant difference in landscape and ecosystem types. The other portion of the group members were locals involved with Yuba-Sutter 4-H. We discussed the role of the REC system, focusing on our own Center and why it is important to have research facilities available. Previous projects, such as the Forbes Hill Oak Clearing, were talked about and visually showcased. The tour concluded at the charming Yuba River Education Center, following a short hike on one of our nature trails.

It was a relaxing, educational, and enjoyable interaction with young aspiring minds and devoted adults. The staff at SFREC are looking forward to the next engagement involving 4-Hers or other local youth. Conservation, cooperation, communication, and commitment. These are four concepts that were highlighted that I hope our visitors will remember, practice, and share.

The Sierra Foothill Research and Extension Center, part of the University of California Agriculture and Natural Resource Division, is a great resource for researchers, educators, agricultural professionals, conservationists–generally anyone interested in conserving and enhancing rangeland ecosystems and the agricultural industries these systems support.
