Effects of climate on amphibians and reptiles
Amphibians and reptile responses to changing weather conditions provides insights into how climate change will affect these species.
Factors affecting Sudden Oak Death
Multiple studies of the factors affecting the spread and severity of Sudden Oak Death at the Fairfield Osborn Preserve.
Douglas fir encroachment
Douglas fir encroachment into oak woodlands is occurring across the Pacific West and is thought to be caused by a historic reduction in fire frequency. The loss of oak woodlands due to this process is causing declines in biodiversity and abundance of native species. Multiple studies assess rates of conversion at the SSU Preserves.
Osborn Campground design project
We are exploring opportunities for small overnight camping facilities at the Osborn Preserve.
Modifying stream channels to control invasive species
Parts of the Laguna de Santa Rosa have been invaded by non-native Ludwigia. Sonoma Water is removing sediment from the Laguna near Stony Point Road in Rohnert Park to create a narrower, deeper, more shaded channel that could reduce habitat for this species. We are monitoring changes in channel shape and species distribution to determine the efficacy of this approach.
Impacts and control of Himalayan blackberry
Multiple studies investigate impacts and control strategies for non-native Himalayan blackberry, Rubus armeniacus, at the Fairfield Osborn Preserve.
Erosion monitoring in the Copeland Creek watershed
Students have established long-term monitoring transects in the upper watershed at the Fairfield Osborn Preserve, the alluvial fan east of campus, and on the SSU campus.
Designing a solar powered boat
We designed and built a solar-powered canoe to race in the Sacramento Municipal Utility District’s (SMUD) annual Solar Regatta Competition at Rancho Seco Recreational Area on May 4, 2019. This was the third year SSU competed in this race.
Climate change effects on soil
A comparison of roots and soils on south and north facing slopes allows predictions of how a warmer dryer climate will affect plant communities.
Resilience to climate change in the wine industry
We conducted a survey of four wineries in Napa and Sonoma Counties to identify factors affecting their level of preparedness to natural disasters.
