N2 - The efficiency of wetlands in reducing nutrient and sediment concentrations in runoff from agricultural areas can be used as an argument for not tackling nutrient and sediment losses at source within the basin. However, evidence from the Slapton basin shows that this efficiency varies seasonally and is much less marked in the winter than in the summer, pointing to the need for basin management during winter flows. In addition, while wetlands may reduce nutrient and sediment concentrations, thus improving downstream water quality, the accumulation of nutrients and sediments in the wetland can lead to progressive eutrophication and, in addition, terrestrialization of valued wetland habitats, further reinforcing the need for basin source control.
