Title	Delta Landscapes Project
Lead	San Francisco Estuary Institute [SFEI]
Description	The Delta Landscapes Project has developed a body of work to inform landscape-scale restoration of the Sacramento-San Joaquin Delta ecosystem. The project is built on knowledge, first published in 2012's Delta Historical Ecology Investigation, of how the Delta ecosystem functioned in the early 1800s (prior to the California Gold Rush and subsequent landscape-level changes).
Science topics	Fish, Landscape metrics, Marsh wildlife, Restoration planning, Riparian wildlife, Terrestrial wildlife

Title	Delta Landscapes Primary Production Project
Lead	San Francisco Estuary Institute [SFEI]
Description	This project compares first-order estimates of primary production among five major groups of primary producers, historically and today, to better identify the potential food production of different habitat types, and inform restoration actions that could increase food availability for wildlife.
Science topics	Primary production, Phytoplankton, Emergent macrophytes, Epiphytic algae, SAV and FAV

Title	Yolo Bypass Fish Monitoring
Lead	California Department of Water Resource [DWR]
Description	California Department of Water Resources (DWR) has operated a fisheries monitoring program in the Yolo Bypass, a seasonal floodplain and tidal slough, since 1998. The objectives of the Yolo Bypass Fish Monitoring Program (YBFMP) are to: (1) collect baseline data on lower trophic levels (phytoplankton, zooplankton, and aquatic insects), juvenile fish and adult fish, hydrology, and water quality parameters;(2) investigation of the temporal and seasonal patterns in chlorophyll-a concentrations, including whether high concentrations are exported from the Bypass during agricultural and natural flow events and the possibility of manipulating bypass flows to benefit listed species like Delta Smelt (Hypomesus transpacificus) and Chinook salmon (Oncorhynchus tshawytscha). The YBFMP operates a rotary screw trap and fyke trap, and conducts biweekly beach seine and lower trophic surveys in addition to maintaining water quality instrumentation in the bypass. The YBFMP serves to fill information gaps regarding environmental conditions in the bypass that trigger migrations and enhanced survival and growth of native fishes, as well as provide data for IEP synthesis efforts.

Title	Effects of drought and elevated nutrients on invasion by Lepidium latifolium and implications for carbon storage in tidal wetlands of the San Francisco Bay- Delta
Lead	Delta Stewardship Council - Delta Science Program
Description	The Delta ecosystem is under threat from multiple concurrent stressors, including drought, nutrient pollution, and invasion by non-native species. Lepidium latifolium is an invasive peren- nial plant that displaces native species and may reduce carbon storage in tidal marshes. Preliminary data suggest that drought may be detrimental to L. latifolium invasion, whereas elevated nutrients may promote invasion. Using experimental manipulation of tidal marsh plots, this project will test the impact of drought and elevated nutrients on the invasion of L. latifolium. The results will inform management of L. latifolium in the Bay Delta by identifying its vulnerabilities to climatic and nutrient conditions, and will be shared with management agencies including East Bay Regional Parks, San Pablo Bay National Wildlife Refuge, and Palo Alto Baylands, among others. The results will also be integrated with the PI’s dissertation research on the carbon storage capacity of L. latifolium, in order to inform wetland carbon offset policies.
