Sierra Foothill REC Blog
In mid November, SFREC partnered with Grass Valley Charter School and Twin Ridges Home Study by bringing students to the center to catch a glimpse of salmon spawning in the Lower Yuba River. The opportunity to observe salmon spawn is a way for...
Students build a fake redd to hold their eggs. To make sure their eggs would be able to safely hatch they thought about how to build a redd that would protect their eggs.
Students are out in the "ocean" during the adult stage trying to find "food" before they head back to home streams to spawn. This type of play can help to solidify learning for young students.
Students get a closer look at the early stages of the salmon, egg, alevin, and fry. This small display allows for an up close look at the hard to see stages of a salmon's life.
Last month, teachers and educators from around Northern California came together for a weekend to learn about best practices for science education with a Forestry Institute for Teachers+ (FIT+) workshop. FIT+ is a new professional development program...
Teachers practice one of Project WET's lessons. This kind of hands-on experience makes them more likely to use a lesson in their own classroom.
Participants collect benthic macroinvertebreates from the Lower Yuba River.
After collecting the benthic macroinvertebrates, they are analyzed to gauge river health. This is just one example of an extension that teachers can combine with Project WET activities.
Proud graduates of the first SFREC FIT+ workshop, ready to bring their new curriculum back to their students.
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...
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.

Figure 1. a) Grazing legacies were created over four years using a combination of mowing and trampling. Here cows are herded in the “moderate grazing” treatment. Photo credit: W. Stanley Harpole. b) Rainfall conditions were altered using shelters and irrigation to create wet and dry conditions, replicated across areas with experimentally-created legacies of low and moderate grazing.

On October 21st and 22nd, UCCE Farm Advisor, Roger Ingram and the Sierra Foothill Research and Extension Center hosted a Low-Stress Stockmanship School taught by Steve and Susan Cote. Steve has 27 years of experience as a range-soil conservationist for...
The Sierra Foothill Research and Extension Center in Browns Valley, CA utilizes 130 acres of summer irrigated pasture for cattle grazing. SFREC's irrigation water is supplied by a local water district via pipelines and open ditch distribution...
