Healthy Soils Demonstration Project Update

Cattle grazing in the project area.

Spring is here and the Healthy Soils Demonstration Project (to read about the background of this project, click here) has been busy since the composts were applied last fall. We have observed the onset of spring, the grasses and wildflowers on the plots...

Healthy Soils Demonstration Project Launch Success

Monitoring greenhouse gases on food waste compost plot

A Healthy Soils Demonstration project was recently launched at Sierra Foothill REC in experimental rangeland plots in the Forbes pasture.   This project is funded by the California Department of Food and Agriculture and the University of...

URGENT: Post Fire Research Opportunities at Hopland REC

HREC and Post-Fire Research Opportunities

What is HREC?

The UC Hopland Research & Extension Center (HREC) is a multi-disciplinary research and education facility in Mendocino County located in the foothills of the Coast Range about two hours north of Berkeley. As part of the UC system for over 65 years, we are stewards of more than 5,300 acres of oak woodland, grassland, chaparral, and riparian environments.  Elevation at the center ranges from 500 ft to 3,000 ft. HREC currently maintains a research flock of about 500 breeding ewes that have been the subjects of numerous studies on ranching practices, range management, livestock nutrition, wool production and breeding.  Field experiments and demonstrations conducted here since 1951 have led to more than 1,500 publications in animal science, entomology, plant ecology, public health, watershed management, and wildlife biology.  Our website is hrec.ucanr.edu.

The River Fire

As part of the Mendocino Complex fire, the River Fire burned through HREC on the evening of July 27 and into July 28.  Approximately 3,000 acres of our center burned in this fire. Due to the concentrated efforts of Center staff and Cal Fire crews, all of our employees, residents, sheep, livestock dogs, offices and residences were saved.  Below please find the burn map of our property.  All of the black area to the north was burned and the dark red patches were areas of vegetation that remained unburned. The fire intensity varied greatly as did oak survival. You will see two smaller burned areas in the southern part of the property that were prescribed burns performed in June of this year.

Research Opportunities

While this was a blow to current research, pastures, and water infrastructure, we also see this as a wonderful opportunity.  Due to extensive historical data sets and ongoing research projects, coupled with a variety of grazed and ungrazed pastures, and prescribed burn plots for comparison with wildfire, there is enormous potential for pre- and post-fire studies in the fields of:

  • Watersheds and hydrology; fire science; plant science; soil science; entomology and parasitology; wildlife and wildlife ecology; rangeland management; grazing practices as fire suppression…..

To support this research, HREC offers:

  • A well maintained network of roads that accesses almost all parts of the property, vehicles to use.
  • A fully equipped shop staffed by employees skilled in fabrication and repair of research equipment

o    Electrical, wood working, welding and metal fabrication, mechanical

  • Skilled staff trained in field work techniques, with long histories of successful research support
  • Fiber optic internet with Wi-Fi access throughout headquarters, strong cell service in most areas
  • A vault of raw data, photos, and final papers from research conducted at HREC.
  • Warehouses for storing equipment, a variety of accommodations from dorms to private houses
  • Wet and dry lab space (undergoing renovation during fall 2018, available spring 2019)
  • Lysimeter with available watering system, electrical connections, and fiber optic access point
  • A research flock of sheep consisting of just under 500 breeding ewes, with all needed facilities and RFID tracking
  • Fenced pastures and biological reserve areas for different treatment plots and controls
  • A fully equipped conference facility with A/V equipment and fiber optic connections

Next Steps

  • Zoom meeting on September 7th, 10am. More in depth information, Q&A.
  • Field day on October 19th, 10am-5pm. Presentations, brainstorming, Q&A, site tours, available accommodations
  • To register for either event follow this link: http://ucanr.edu/survey/survey.cfm?surveynumber=25451

Researcher Spotlight: Managing Rangelands for the Bad Times as Well as the Good

Figure 2. Total cover and biomass responses to rainfall and grazing legacy over three years (± SE). Dark squares indicate a legacy of moderate grazing – which created a diverse mix of grass and forb species - and light circles indicate a legacy of low grazing – which shifted the community to only dominant grasses.

Over the last few years Californians have grappled with how to manage lands during times of both drought and plentiful rainfall. At SFREC and on Central Valley rangelands, one question is whether management that promotes high forage in wet years alters...
