    • Unvegetated to Vegetated Ratio in coastal wetlands along the U.S. Atlantic Coast (16-bit GeoTIFF)

    Metadata Updated: October 29, 2025

    Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using Landsat 8 satellite imagery for the coastal areas of the contiguous United States (CONUS). These datasets provide annual averages of 1) developed, 2) vegetated, 3) unvegetated fractional covers and 4) an unvegetated to vegetated ratio (UVVR) at 30-meter resolution over the coastal areas of the contiguous United States for the years 2014-2018. Additionally, multi-year average values of vegetated fractional cover and its standard deviation are provided for the coastal wetlands of the contiguous United States based on the National Wetland Inventory delineation. Finally, a UVVR based on the annually-averaged vegetated fractional cover is also provided for the same extent.
