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.

Summer “drought” is a fact of life in the Sierra Foothills. Our Mediterranean climate is characterized by cool and (hopefully) wet winters and hot, dry summers. While the higher elevations in the Sierra Nevada often receive summer...
At the Sierra Foothill Research and Extension Center in Browns Valley, our mission is to foster and support research, education and outreach programs focused on key agricultural and natural resource themes relevant to the Sierra...
