Location: Kenya

Signs of progress: The Mombasa Marine National Park is adjacent to the most heavily populated tourist beach along the Kenyan coast. The reefs are threatened by overfishing, destructive fishing from beat seining and spear fishing, organic pollution and sedimentation, and tourist damage from trampling. The reduction of predatory fish led to increases in burrowing sea urchins, whose excavations began to reduce the reef framework to rubble. In 1989, the area was officially gazetted by the Kenya government as a marine park. Management activities include patrolling, beach cleaning, regulation of tourist activities (including glass bottom boat excursions), and maintenance of moorings. Surveys carried out since 1988 have shown a major increase in fin fish size, abundance, and diversity; recorded coral cover has increased from 8 to 30 percent; and sea urchin numbers have decreased steadily throughout the survey period. The number of sea turtles recorded nesting in the area has also increased.
