Wetland value
From the US Fish and Wildlife Service:
Wetlands provide many functions that are valued by people. These functions (and their values) include: surface water storage (flood control), shoreline stabilization (wave damage protection/shoreline erosion control), stream flow maintenance (maintaining aquatic habitat and aesthetic appreciation opportunities), groundwater recharge (some types replenish water supplies), sediment removal and nutrient cycling (water quality protection), supporting aquatic productivity (fishing, shell fishing, and waterfowl hunting), production of trees (timber harvest), production of herbaceous growth (livestock grazing and haying), production of peaty soils (peat harvest), and provision of plant and wildlife habitat (hunting, trapping, plant/wildlife/nature photography, nature observation, and aesthetics).
Destruction of wetlands eliminates or severely minimizes their functions and values. Drainage of wetlands prevents surface water storage and reduces their water quality enhancement function, while accelerating the flow of water downstream which may cause increased flood damages. Wetland filling does likewise as well as destroying vital habitats for native fish and wildlife species. The vast majority of wetland benefits accrue to the general public which makes it important to conserve these valuable natural resources.
