Dugong dugon are the last extant species in the Family Dugongidae and are listed as Vulnerable to extinction by the IUCN Red List. The dugong population is believed to be in decline globally. Throughout its range, relic populations remain and are separated by large areas where populations have disappeared (Marsh & Lefebvre 1994). The degree of the decline of numbers or fragmentation of its range is not known for any country. For many countries the only information available is from incidental sightings, drownings and anecdotal information. The Pacific region supports the world's largest remaining population of dugongs (Marsh et al. 2002). Dugong occur in most of Melanesia, Papua New Guinea (PNG), the northeast and east coasts of Australia and as far east as Vanuatu.. The current status of dugongs is unknown throughout the region (Marsh et al. 2002) and information on dugong distribution and abundance is outdated or non-existent. It is likely that dugongs are widely distributed in small numbers in much of PNG. the Solomon Islands and Vanuatu and that larger numbers occur in the Papua New Guinea waters of Torres Strait. Marsh et al. (2002) states that their reliance on relatively shallow water seagrass beds for food, limits the ability of dugongs to travel between islands and continents that are separated by extensive areas of deep water. For this reason, many island populations become essentially isolated, making these populations especially vulnerable to extinction.

The islands of Beliliou (Peleliu) and Ngemelis and stretches of beach along the east coast of Babeldaob, Republic of Palau, were surveyed for evidence of hawksbill, Eretmochelys Imbricata and green, Chelonia mydas turtles during the peak of the turtle nesting season. Incidental sightings of nesting seabirds and Micronesian Megapodes, Negapodius laperouse were also recorded. Ngerduais beach on the east coast of Babeldaob was the only area surveyed which showed any recent signs of nesting turtles. Local information suggests that only sparse nesting has ever taken place in Babeldaob and the islands of Ngemelis, Angaur and Beliliou in recent years. Micronesian Megapodes are reported rare on these islands, and there was no evidence of Megapode nesting on any of the sites surveyed. Although many seabirds are known from these islands, none were observed nesting. However, the Vanikoro Swiftlet, Aerodramus vanikorensis, Collared Kingfisher, Halcyon chlorls, Rufous Night Heron, Nycticorax caledonicus, Pacific Reef Heron, Egretta sacra, and Black Noddy, Anous minutus, were sighted on several of the islands surveyed. The limited evidence of recent turtle nesting and the lack of evidence of Megapode and seabird nesting combined with the information provided by members of the local communities, indicates that the areas surveyed during this phase of the Rapid Ecological Assessment are not significant nesting areas for these wildlife at this time.
