Observations on macrobenthic invertebrates and wader bird assemblages in a protected marine mudflat in Bahrain

Abstract

Intertidal mudflats in Bahrain provide essential feeding grounds for a good number of shorebirds. The spatial distribution of soft-sediment macrobenthic invertebrate assemblages inhabiting a mudflat designated as a natural marine protected area was investigated to characterize shorebird food supplies. Molluscs accounted for 88% of the total macroinvertebrates community, reflecting a dominance of gastropod grazers. Six species of wading birds were recorded feeding in the protected area. Bird disturbance associated with human recreational activities that may interfere with the conservational benefits of this protected area was explored. This study highlighted the crucial need for management plans for protected areas and for further research concerning bird disturbance.
