Abstract

Strangford Lough is a sheltered marine inlet on the east coast of Co. Down, Northern Ireland. The distribution of Zostera in the Lough and its exploitation by wildfowl was investigated. There was an estimated 1100 tonnes (fresh weight) of Zostera in the Lough in October 1991 covering some 6.3 km2 of the northern mudflats and representing some 12% of the total intertidal area of the Lough. This was regarded as peak biomass. By January 1992, Zostera was reduced following grazing by wildfowl and weathering to 20% of the initial biomass as measured in the exclusion experiment. The above-ground and below-ground biomass of Zostera were not equally affected with reduction to 7% and 26%, respectively.
