摘要

Waterfowl and migratory birds rely on wetland habitat in coastal temperate regions for breeding and feeding. Over the past few decades, freshwater impoundments have been created in the Cumberland Marsh Region of Canada to compensate for regional loss of ecosystem services and habitat. The objective of our study was to determine whether freshwater impoundments underlain by tidal marsh sediments, and located where marine influences exist, are predisposed to higher nutrient levels and more conducive to productive habitat than waterfowl habitat elsewhere in Canada and the northeastern United States. We found that impoundment subsurface waters were generally circumneutral with moderate concentrations of dissolved organic carbon ranging between 6.30 and 13.90mg/L. Furthermore, these impoundments generally had higher concentrations of cations (Ca, K, Mg, Na), anions (Cl-, SO42-), and nutrients (phosphorus, nitrogen, dissolved organic carbon) than other freshwater waterbodies studied for waterfowl in central Ontario, Maine and Nova Scotia, but lower concentrations than found in Prairie potholes. Our data indicate that a lack of hydrological connectivity and nutrient pathways may be limiting impoundments from reaching their full potential for supporting wildlife. We recognize that additional research on fostering ecosystem services from wetland restoration and creation projects is necessary on former tidal marshland.
