The dugong (Dugong dugon) is the only herbivorous mammal that is strictly marine, and is the only extant species in the Family Dugongidae. It is listed as vulnerable to extinction at a global scale by The World Conservation Union (IUCN). The dugong has a large range that spans some 37 countries and territories and includes tropical and subtropical coastal and island waters from East Africa to Vanuatu, between about 26° north and south of the Equator. The purpose of this document is to present a global overview of the status of the dugong and its management in the various countries in its range. We aimed to provide comparative information that will enable individual countries to develop their own, more detailed, conservation plans. This document contains information on dugong distribution and abundance, threatening processes, legislation, and existing and suggested research and management initiatives for 37 countries and territories in the dugong’s known range. The report is organised in a geographical sequence from the Western Indian Ocean region, through to the South West Pacific. Chapter One introduces the Dugong; Chapter 2 comprises information on East Africa; the Red Sea and the Arabian Gulf. Chapter 3 discusses India and Sri Lanka; Chapter 4 presents data from Southeast Asia including Japan, Taiwan (China), China, the Philippines, Vietnam, Cambodia and Thailand; Malaysia, Singapore and Indonesia; Chapter 5 discusses Palau, Papua New Guinea, the Solomon Islands, New Caledonia and Vanuatu; and Chapter 6 presents information from Australia.
