    Pacific Flyway Shorebird Survey

    Lead Point Blue Conservation Science
    Description PFSS is a coordinated multi-partner monitoring program led by Point Blue Conservation Science designed to guide the management and conservation of wintering shorebirds in the Pacific Flyway. The PFSS contributes data to the Migratory Shorebird Project, the largest coordinated survey of wintering shorebirds on the Pacific Coast of the Americas spanning 10 countries from Canada to Peru.

    Aquatic Invasive Species Programs

    Lead California Department of Parks and Recreation [PARKS]
    Description The Aquatic Weed Control Program includes both floating and submersed aquatic vegetation. DBW uses an Integrated Pest Management strategy with the following components: - Public information and education - Prevention - Pre-established action levels for chemical, biological and physical control - Environmental monitoring Since submersed and floating aquatic vegetation are well established in the Sacramento- San Joaquin Delta, eradication may not be feasible, while controlling invasive growth is likely to lessen negative economic and biological impacts.
    Science topics Salinity, Water temperature, Dissolved oxygen, pH, Turbidity, Main channels, Sloughs, Backwater, Floating aquatic vegetation, Water hyacinth, Brazilian waterweed, Spongeplant, Conductivity, Saltwater / freshwater marshes, Other species

    Soil Survey Geographic Database [SSURGO]

    Lead U.S. Department of Agriculture [USDA]
    Description The SSURGO database contains information about soil as collected by the National Cooperative Soil Survey over the course of a century. The information can be displayed in tables or as maps and is available for most areas in the United States and the Territories, Commonwealths, and Island Nations served by the USDA-NRCS. The information was gathered by walking over the land and observing the soil. Many soil samples were analyzed in laboratories. The maps outline areas called map units. The map units describe soils and other components that have unique properties, interpretations, and productivity. The information was collected at scales ranging from 1:12,000 to 1:63,360. More details were gathered at a scale of 1:12,000 than at a scale of 1:63,360. The mapping is intended for natural resource planning and management by landowners, townships, and counties. Some knowledge of soils data and map scale is necessary to avoid misunderstandings. The maps are linked in the database to information about the component soils and their properties for each map unit. Each map unit may contain one to three major components and some minor components. The map units are typically named for the major components. Examples of information available from the database include available water capacity, soil reaction, electrical conductivity, and frequency of flooding;yields for cropland, woodland, rangeland, and pastureland;and limitations affecting recreational development, building site development, and other engineering uses. SSURGO datasets consist of map data, tabular data, and information about how the maps and tables were created. The extent of a SSURGO dataset is a soil survey area, which may consist of a single county, multiple counties, or parts of multiple counties. SSURGO map data can be viewed in the Web Soil Survey or downloaded in ESRI® Shapefile format. The coordinate systems are Geographic. Attribute data can be downloaded in text format that can be imported into a Microsoft® Access® database.

    Statewide Crop Mapping

    Lead Land IQ
    Description Agricultural lands are mapped in the state of California each year, beginning in 2014. In 2014, DWR contracted LandIQ to undertake a comprehensive mapping project for the the state of California. Field-scale assessment of agricultural land use and urban/managed wetland boundaries were determined, and these 2014 data are publicly available on the DWR Land User Viewer interactive map. Following this 2014 work, LanIQ was subsequrntly contracted to continue mapping in and around the state of California, focused on mapping agricultural lands only (2014-ongoing). Aerial imagery provided by the United States Department of Agriculture (USDA) National Agriculture Imagery Program (NAIP) was collected throughout the summer of 2014 by the USDA and used for field delineation, classification and QA/QC of the final product. Multiple Landsat 8 images were used for the initial crop classification. Imagery from the Landsat 8 satellite is free and available every 16 days and provided for temporal analysis throughout the growing season. Ground truth data were collected during the 2014 growing season prior to the initiation of this project. These data were used for training and validation of the mapping analysis. Field data from over 15% of all irrigated land in the Central Valley was collected. 25% of the ground truth data were set aside for independent validation. Analysis in areas that lacked ground truth data was performed using imagery and classification approaches established in areas that were informed by training data.

    National Water Use Science Project [NWUSP]

    Lead U.S. Geological Survey [USGS]
    Description The USGS National Water Use Science Project (NWUSP), a component of the Water Availability and Use Science Program (WAUSP), facilitates the 5-year compilation of water use estimates for the United States as part of the National Water Census (NWC). The NWC, implemented as part of the SECURE (Science and Engineering to Comprehensively Understand and Responsibly Enhance) Water Act (Subtitle F of Public Law 111-11, the Omnibus Public Land Management Act), provides data and tools designed to support water managers in the accurate assessment of water availability at regional and national scales (https://water.usgs.gov/ watercensus/). Water managers across the United States require more complete, timely, and accurate water-availability information to support policy and decision-making, specifically, data associated with water withdrawals and consumptive use. Recognizing the limitations of current water-use data, the SECURE Water Act authorized a program that supports activities related to data collection and methods research and development at the State level. The USGS Water-Use Data and Research program (WUDR) will provide financial assistance through cooperative agreements with State water resource agencies to improve the availability, quality, compatibility, and delivery of water-use data that is collected or estimated by States. The Act requires that these State water use and availability datasets be integrated with appropriate datasets that are developed and/or maintained by the USGS.

    National Geospatial Agriculture Monitoring

    Lead National Agricultural Statistics Service [NASS]
    Description "US Department of Agriculture (USDA), National Agricultural Statistics Service (NASS) collects and provides timely, accurate, and useful statistical information in service to US agriculture. The Spatial Analysis Research Section (SARS) within the Research and Development Division of NASS has produced a yearly Cropland Data Layer (CDL) product based on mid-resolution satellite data and high quality ground truth since 1997. This agricultural geospatial data is a crop and other specific land cover classification encompassing the entire contiguous United States. It provides geo-referenced, high accuracy, 30 or 56 m resolution, crop specific cropland land cover information. This product has been extensively used by policy and decision makers, scientists, researchers, educators, and farm producers for land cover monitoring, agricultural sustainability, crop acreage and yield estimation,disaster assessment, bioenergy crop inventory, food security policy, environmental assessment, carbon accounting, and other research interests that are of vital importance to American agriculture and its economy."
