    Delta Wetland Resilience and Blue Carbon

    Lead San Francisco Estuary Institute [SFEI]
    Description This project estimates carbon storage for the past, present and future Delta, as well as GHG fluxes and elevation change based on chosen restoration and rice farming scenarios in the future Delta using the Delta Landscape Scenario Planning Tool. The project also investigates how well the current organic matter parameterizations and inorganic sediment parameterization in the Marsh Equilibrium Model (MEM) represent Delta marsh accretion processes. Knowledge of marsh accretion and migration will be used to develop a spatial conceptual model of marsh resilience in the Delta.

    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).

    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.

    Delta Landscape Scenario Planning Tool

    Lead San Francisco Estuary Institute [SFEI]
    Description The Delta Landscapes Scenario Planning Tool is a set of resources to assist users with developing, analyzing, and evaluating different land use scenarios in the Delta. The tool is designed to inform ongoing and future restoration planning efforts by assessing how proposed projects will affect a suite of landscape metrics relating to desired ecosystem functions.

    Delta Salmon Rearing Project

    Lead San Francisco Estuary Institute [SFEI]
    Description This project summarizes existing research and knowledge around suitable rearing habitat for Chinook salmon in the Sacramento-San Joaquin Delta;identifies areas of suitability for rearing salmon using a combined suitability analysis of four mapped habitat parameters;and provides recommendations for types of restoration needed to improve or restore rearing habitat, as well as to identify where in the Delta these restoration efforts could be prioritized.

    Delta Regional Monitoring Program

    Lead San Francisco Estuary Institute [SFEI]
    Description The Delta Regional Monitoring Program (RMP) is a stakeholder-directed project formed to develop water quality data necessary for improving our understanding of Delta water quality issues.

    Bioaccumulation Monitoring Program

    Lead San Francisco Estuary Institute [SFEI]
    Description The Bioaccumulation Oversight Group (BOG) is a subcommittee of the SWAMP Roundtable that provides oversight of SWAMP's statewide bioaccumulation monitoring program. The BOG is also a workgroup of the California Water Quality Monitoring Council, and in this role manages the Safe to Eat Portal and is a forum for coordination of bioaccumulation monitoring in California. The mission of the BOG is to assess the impacts of contaminants in fish and shellfish on beneficial uses in California water bodies through statewide monitoring under SWAMP and perform syntheses of information from other studies, and to develop an internet portal that presents this information to decision-makers and the public in a form that they can easily use. See the Workgroup Charter for more information.

    California Aquatic Resource Inventory [CARI]

    Lead San Francisco Estuary Institute [SFEI]
    Description The California Aquatic Resource Inventory is a standardized statewide map of surface waters and related habitat types, including wetlands, rivers, streams, lakes, and their riparian areas. The CARI v0 dataset includes: the National Wetland Inventory (NWI, last updated in 2010) of the US Fish and Wildlife Service, the National Hydrography Dataset (NHD, high resolution dataset at 1:2400 scale, last updated in 1999) of the US Geological Survey, three regional datasets developed by SFEI's GIS team using CARI's standardized, and more detailed, mapping protocols and used to demonstrate the WRAMP framework. Links to more information about these mapping efforts are listed below under "Subprojects" (below). San Francisco Bay Area Aquatic Resources Inventory (BAARI)- 2011 Lake Tahoe Basin (TARIv2.1) - 2016 Laguna de Santa Rosa Plain (near Santa Rosa ,CA. NCARI) - 2013, and Six County Aquatic Resources Inventory (including Sacramento, Placer, Yolo, El Dorado, Yuba, and Sutter Counties, California) developed by the US Army Corps of Engineers (Sacramento District) through federal funding - 2010.

    Suisun Landscapes: historical ecology, functional metrics, and community priorities for landscape planning

    Lead San Francisco Estuary Institute [SFEI]
    Description

    To support management planning in Suisun Marsh, this project is developing a body of science and tools to understand past, present, and potential future changes to the Marsh’s ecological patterns, processes, and functions. This project builds on SFEI’s prior work in the Delta, extending historical ecology mapping, landscape change studies, and the Landscape Scenario Planning Tool to cover Suisun's historical and present-day landscapes. Through spatially explicit representations of the historical function and condition of the marsh and analyses of landscape metrics, this project is evaluating changes over time in landscape support for ecosystem functions and services in Suisun. In order to incorporate diverse perspectives into planning resources, project activities include engagement with local tribes and community members to understand community interests, priorities, and uses of the Marsh. Findings will be shared through a report and article for both technical and general audiences, and spatial analyses and data layers will be made available through the Landscape Scenario Planning Tool.

    Eco-Cultural Renewal of Delta Tule Landscapes

    Lead San Francisco Estuary Institute [SFEI]
    Description

    The Eco-Cultural Renewal of Delta Tule Landscapes project is a collaboration between the San Francisco Estuary Institute (SFEI) and two Delta area Tribes: the Shingle Springs Band of Miwok Indians (SSBMI) and the Colfax Todds Valley Consolidated Tribe (CTVCT). This project's goals are to communicate the central importance of Traditional Ecological Knowledge (TEK) in creating and maintaining resilient Delta landscapes and to advance the integration of TEK into Delta science, management strategies, and policies in a way that supports the ecological and cultural value of the Sacramento-San Joaquin Delta, a region of profound ecological and cultural significance. TEK is the evolving knowledge acquired by indigenous peoples over hundreds or thousands of years through direct contact with the environment. In the Delta, Tribes used TEK to tend wetlands and foster abundant populations of the plants and animals they harvested. This project aims to elevate TEK in the Delta as an essential tool to restore and build the resilience of species, habitats, and ecosystem processes that have been devastated since European
