Its mission is to identify, designate, protect and manage the ecological, recreational, research, educational, historical, and aesthetic resources and qualities of nationally significant coastal and marine areas. The existing marine sanctuaries differ widely in their natural and historical resources and include nearshore and open ocean areas ranging in size from less than one to over 5,000 square miles. Protected habitats include rocky coasts, kelp forests, coral reefs, sea grass beds, estuarine habitats, hard and soft bottom habitats, segments of whale migration routes, and shipwrecks. Because of considerable differences in settings, resources, and threats, each marine sanctuary has a tailored management plan. Conservation, education, research, monitoring and enforcement programs vary accordingly. The integration of these programs is fundamental to marine protected area management. The Marine Sanctuaries Conservation Series reflects and supports this integration by providing a forum for publication and discussion of the complex issues currently facing the National Marine Sanctuary Program.

FEINGOLD,1 SUSAN L. THORNTON,1 KENNETH W. BANKS,2 NANCY J. GASMAN,2 DAVID GILLIAM,1 PAMELA FLETCHER,2 and CHRISTIAN AVILA1 ABSTRACT Coral reefs at 13 sites ranging in depth from 1-16 m near Hopetown, Abaco Islands, Bahamas were surveyed utilizing the Atlantic and Gulf Rapid Reef Assessment (AGRRA) benthos protocol. A total of 35 species of scleractinian corals and 2 species of calcareous hydrocorals were observed. The overall coral cover averaged just over 14%. Among corals that were at least 10 cm in diameter, small colonies (<40 cm diameter) predominated in all sites except for the Fowl Cay pinnacles where 68% were larger than 60 cm in diameter.

  • Estimating Multi-Species Trends in Reef Fishes from a Large Volunteer Generated Data Set: a New Tool for Management
    Estimating Multi-Species Trends in Reef Fishes from a Large Volunteer Generated Data Set: A New Tool For Management by Brice X. Semmens1, J. L. Ruesink1, and C.V. Pattengill-Semmens2 1University of Washington, Department of Zoology Box 351800, Seattle, WA 98195-1800, 206-685-6893, [email protected]; 2Reef Environmental Education Foundation, P.O. Box 246, Key Largo, FL 33037 ABSRACT Coral reefs are subject to major anthropogenic impacts worldwide and sites in decline are prime candidates for management and restoration. In assessing trends, it is imperative to have data from a wide area, over several years, and for many species. We assessed trends in 50 common coral reef fishes at 21 sites throughout the Florida Keys National Marine Sanctuary, based on volunteer surveys for the Reef Environmental Education Foundation (REEF) from 1993-1999. Analytical techniques were modified from those applied to the Breeding Bird Survey to detect sites with multi-species declines (ordered logistic regression followed by probit-normal analysis). Our results identify a subset of reef sites where trends were relatively poor for most fish species. At East Sambo in particular, a shift in fishing pressure may be reducing the density of fishes. No clear differences in trends were evident where fishing was prohibited in 1997 relative to other fished sites throughout the Florida Keys, although the expectation is that fish should increase in the future. As volunteer-generated data continue to accumulate, they will provide increasingly useful indicators of community level changes. INTRODUCTION Effective management of coral reefs requires information on species distributions and how these distributions change in time and space (Ginsburg 1993).
