Habitat Management Projects
Copeland Creek Riparian Restoration Project
2013-present: The section of Copeland Creek that runs across SSU lands are heavily invaded by blackberry and other undesirable species. An integrated vegetation management plan and long-term consistent treatments are needed for successful restoration. Students are developing grant applications, treatment plans, cultivation of natives, and monitoring. Crews of disadvantaged youth undertake needed restoration work each summer.

Do constructed vernal pools provide habitat for endangered California tiger salamanders?
2015-16: Constructed vernal pools have been used as a method for creating California tiger salamander habitat. We investigate whether constructed pools are as effective as natural pools in supporting tiger salamander populations.

Oral histories of land use changes and their affects on riparian areas
2015-16: Changes in land management have had significant effects on riparian areas of the North Coast. We conduct interviews with neighbors of the Fairfield Osborn Preserve (Sonoma Mountain) and Galbreath Wildlands Preserve (Outer Coast Range) to find out more about land use and riparian changes in the last 50 years.

Determinants of red-legged frog abundance in critical habitat
2015-16: The top of Sonoma Mountain is designated critical habitat for threatened red-legged frogs. Over a dozen ponds within the area have potential to support breeding. This study compares red-legged frog adult and egg mass abundance to water quality, invertebrate diversity, and the occurrence of predatory insects.

Management implications of climate change impacts on amphibians and reptiles
2015-16: As seasonal changes in temperature and precipitation are altered by climate change, amphibians and reptiles face new challenges. An improved understanding of how abiotic conditions and species interactions affect abundances of these vertebrates in a variety of habitat types can inform land management practices and allow scientists to predict the impacts of climate change on ecosystems. This study incorporates IT technology and citizen science.

Evaluation of fish habitat restoration on Dry Creek
Spring 2015: A backwater channel on Dry Creek was constructed in the winter of 2012. This project evaluates whether the channel provides a refuge for Steelhead and Coho Salmon as planned.

Spring 2014 - Present: The Land Management Program prepares 20 students each Spring semester to work on ecological restoration projects at partner sites in Sonoma County. With WATERS support, a watershed unit was introduced into the program and included training in riparian restoration strategies and watershed management principles and skils. Partner organizations provided training and supervised students at work sites. Some students in the program additionally undertook independent watershed related research projects.

Spring 2014 - present: Students documented insect biodiversity at three restoration sites in the City of Santa Rosa: Colgan Creek, Fresno Avernue Migration Corridor Preserve, and Samuel P Jones Shelter and Community Center. Comparisons before and after restoration determine how restoration efforts affect insect biodiversity.

February 2012-present: New riparian management techniques are focused on promoting native species diversity and maintaining flood capacity. These techniques include removing and controlling non-native blackberry, active restoration of native plant species, limbing the lower branches of existing trees to promote taller, shadier canopies and to allow maximum flow during floods. Do these techniques meet the multiple objectives of controlling floods and increasing the abundance of native species? What are the effects on other organisms (e.g., birds and fish)? Can successional processes be ‘fast-forwarded’ to result in taller, shadier, riparian communities with an understory dominated by native plant cover?

Vegetation measurements of this project are part of a separate SCWA-SSU contract to Caroline Christian
Spring 2013-present: Stewardship and restoration of watercourses requires physical activity to clean up refuse, maintain paths, plant natives, and remove invasive species. At the same time, these activities can potentially improve the health of participants. This project examines the effects of self - paced restoration activities on heart rate and metabolism.
