| description | <p>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 <span class="inline-formula">16×10<sup>6</sup></span> km<span class="inline-formula"><sup>2</sup></span>.
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 km<span class="inline-formula"><sup>2</sup></span>), with a global median size
ranging from 0.018–0.138 km<span class="inline-formula"><sup>2</sup></span>. 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
