Abstract
Abstract. Non-floodplain wetlands – those located outside the floodplains
– have emerged as integral components to watershed resilience, contributing
hydrologic and biogeochemical functions affecting watershed-scale flooding
extent, drought magnitude, and water-quality maintenance. However, the
absence of a global dataset of non-floodplain wetlands limits their
necessary incorporation into water quality and quantity management decisions
and affects wetland-focused wildlife habitat conservation outcomes. We
addressed this critical need by developing a publicly available “Global NFW”
(Non-Floodplain Wetland) dataset, comprised of a global river–floodplain map
at 90 m resolution coupled with a global ensemble wetland map incorporating
multiple wetland-focused data layers. The floodplain, wetland, and
non-floodplain wetland spatial data developed here were successfully
validated within 21 large and heterogenous basins across the conterminous
United States. We identified nearly 33 million potential non-floodplain
wetlands with an estimated global extent of over 16×106 km2.
Non-floodplain wetland pixels comprised 53 % of globally identified
wetland pixels, meaning the majority of the globe's wetlands likely occur
external to river floodplains and coastal habitats. The identified global
NFWs were typically small (median 0.039 km2), with a global median size
ranging from 0.018–0.138 km2. This novel geospatial Global NFW static
dataset advances wetland conservation and resource-management goals while
providing a foundation for global non-floodplain wetland functional
assessments, facilitating non-floodplain wetland inclusion in hydrological,
biogeochemical, and biological model development. The data are freely
available through the United States Environmental Protection Agency's
Environmental Dataset Gateway
(https://gaftp.epa.gov/EPADataCommons/ORD/Global_NonFloodplain_Wetlands/, last access: 24 May 2023) and through
