Abstract: Benthic fauna from two stations within a 5-year old borrow area and two control stations off Hillsboro Beach (Broward County), Florida, were sampled quarterly from June 1977 to March 1978 to evaluate the long-term impact of offshore dredging. Generally enhanced productivities occured within the borrow area, although there was much seasonal variation among the stations. Species diversities were usually higher at the borrow stations than at the control stations. The single exception was due to a high concentration of the bivalve E. Nitena at one of the control stations in June. Although faunal similiary analysis revealed a qualitative change in the fauna of the borrow area, this change is not considered detrimental. Conspicuous patterns of heterogenous faunal distributions were evident in this study, particularly for the bivalve E. Nitena. No lasting detrimental effects, in terms of number of species, faunal densities, or species diversity, resulted from the dredging operation.
