coastal protection against the effects of wind, waves and water currents; conservation of biological diversity – including a number of endangered mammals, reptiles, amphibians and birds; protection of coral reefs, sea grass beds and shipping lanes against siltation; and provision of habitat, spawning grounds and nutrients for a variety of fish and shellfish, including many commercial species High population pressure in coastal areas has, however, led to the -9- - 62 - - 63 - - 64 - - 65 - - 66 - - 67 - - 68 - - 69 - REFERENCES [1] W G Cochran, 1977 Sampling techniques (3rd ed.)
