Wetlands are a critical part of our spatial and temporal landscape, providing distinct ecosystem services. Truly neither land nor water, wetlands are the transitional zone between terrestrial and aquatic ecosystems and as such, have a unique place and function within the landscape. Understanding the functions wetlands serve, in societal, ecological, and economic terms, can strengthen wetland policy and increase positive public perceptions to promote more effective wetland conservation in the United States. By reviewing and aggregating current literature and agency reports, we examine the sustainability of national wetland policy and conservation efforts by analyzing connections between hydrology, ecology, and public perception. Such an integrative attitude toward wetland management allowed for the determination that multifactor approaches to wetland delineation and individualized plans for wetland conservation can help support sustainable wetland policy while preventing further wetland loss in the United States. Sustainable wetland policy can also serve to strengthen the functional uses of restored and created wetlands. Identifying the societal, ecological, and economic components of wetlands now and in the future will better enable scientists, policymakers, and the public to perceive and enjoy conservation benefits associated with wetlands. Without an integrated sustainable approach, the United States might continue to lose wetlands, causing harmful effects to large-scale ecosystems and species populations dependent on wetlands.
