RATES AND DRIVERS OF NITROGEN REMOVAL BY FRESHWATER WETLANDS IN NUTRIENT ENRICHED COASTAL WATERSHEDS

Excess nitrogen (N) inputs to the landscape create many environmental problems that result in harmful algal blooms and threats to aquatic species. Watersheds in the northeastern US typically remove about 80% of this anthropogenic N while in the shallow-sloped watersheds of northeastern Massachusetts, this removal can exceed 90%. Channelized streams are well studied and can have high rates of N removal. In contrast, fluvial wetlands, a prominent element of the aquatic network in many watersheds, have not been as well studied and may contribute disproportionately to N removal at the network scale. We quantified N removal in fluvial wetlands using several approaches, including coupling a dynamic solute addition method with in situ nitrate analyzer technology. N removal as a percentage of inputs ranged from 6.9-36.5% among five different fluvial wetland sites and also varied across seasons. Removal was generally greater in wetlands compared to channelized streams in the region and was in a similar range as removal measured at the patch-scale in surface transient storage areas. This suggests that fluvial wetlands may be responsible for a significant proportion of the total N removal in regions where they are abundant.
