A review of some problems of tropical marine conservation with particular reference to the Tanzanian coast

Abstract

Abstract The productivity, diversity and susceptibility to stress of tropical marine communities are compared with those of temperate marine communities. The question of the i importance of conservation is raised. The applicability of island biogeographical theories in relation to the design of marine reserves is briefly reviewed. It is suggested that the contention that conservation areas should always consist of the largest possible single area is not necessarily correct for the tropical marine environment. Conservation problems of particular habitats within Tanzanian coastal waters are detailed with special reference to the following: coral reefs, rocky intertidal platforms, cliffs, sandy beaches, sandy-muddy tidal flats, seagrass beds, mangroves, estuaries and small islands. The plight of some endangered species is discussed. Conclusions are drawn regarding the present status of marine conservation in Tanzania.
