Copeland Creek can jump its banks, depositing sediments where the creek empties onto the Santa Rosa plain. Flood modeling and field studies help agencies and community groups design solutions.
To determine whether or not invasive turtles are a threat to our native species, we compared abundance of red-eared sliders and western pond turtles at three different locations: Turtle Pond on the SSU campus, Mountain Lake in San Francisco, and Roberts Lake in Rohnert Park.
We studied whether bullfrogs eating large amounts of crayfish showed a reduction in the number of native species they consumed.
Morales et al 2018: Identification of newt species is a challenge for field biologists.
We used pitfall traps to study arthropod diversity on three pond edge habitats at the Colusa National Wildlife Refuge. The greatest arthropod diversity was found in Tule habitat.
The upper watershed of Copeland Creek is known for its landslides, slumps and debris flows. We evaluated sites on SSU Fairfield Osborn Preserve to determine how slope stability is correlated with rock type, and degree of weathering and vegetation.
Soil compaction increases runoff and erosion. Students characterized and studied the cause of soil compaction at multiple sites.
Development of a pilot-scale microbial fuel cell system for treating wastewater from wine production
Use of hiking trails can increase erosion, soil compaction, and transmission of Sudden Oak Death pathogen, Phytophthora ramorum, from surface runoff. We conducted a survey to identify sections of trail at the Fairfield Osborn Preserve (upper Copeland Creek watershed) with excessive erosion.
Tidal salt marshes are important carbon sequestration environments. We analyzed sediment gathered from three core samples at varying distances from a tidal channel to determine carbon accumulation for the past century.
