    • Wetland Moist Soil Seed Productivity Maps for the Central Valley of California 2007 - 2017

    Metadata Updated: July 6, 2024

    We produced a series of maps of moist soil seed plants within managed wetlands in the Central Valley of California from 2007-2011 & 2013-2017. Moist soil seed plants, such as swamp timothy (Crypsis schoenoides) and watergrass (Echinochloa crusgallim), are a critical food source for migratory birds. For each of the Moist Soil Seed maps from 2007 to 2017, we mapped productivity of swamp timothy where swamp timothy was mapped according to a multiple regression of the average log seed head weight per Landsat pixel to Landsat derived values for green chlorophyll index (NIR/green - 1), swir1 reflectance, red green simple ratio (red/green) and SSURGO derived percent clay (STprod). For areas mapped as watergrass, we mapped the green chlorophyll index as an indicator of productivity (WGprod). The final maps show the productivity and extent of two dominant moist soil seed plants within managed wetlands in the Central Valley of California.
