Community dynamics in restored salt marshes

Salt marshes provide many services including nursery habitat for birds and fish, nutrient export to

sun’ounding coastal areas, and sheltering coasts from sea level rise and storm activity. In Atlantic

Canada, there is strong interest in salt marsh restoration. A study was instigated by Ducks Unlimited

Canada in 20 lOin the Bay of Fundy to monitor change in community structure of cells of fannland,

before and after breaching the dikes. Immediately after breaching, much of the cells became mudflat;

with sea level rise and subsidence of the Atlantic coastline, the elevation of the ground is actually

lower behind the dikes than on the shoreward side. The intern will monitor colonization/spread by

halophytic plants, salt panne fonnation, and use by mudflat/salt marsh animals. A better understanding

of community changes and their rates in developing salt marshes is needed to develop sound coastal

management plans, as many dikes are failing and as effects of climate change are increasingly being

felt along our…..
