說明
This dataset is from a paper by Scott Whiting and Michael Guinea (2005) on observations of Dudongs at Ashmore Reef and Sahul Banks, Australia.
A small, but significant, population of dugongs (Dugong dugon) occurs on Ashmore Reef. One sighting in 1996, 130 km east of Ashmore Reef, indicates that dugongs could use other shallow shoals on the Sahul Banks. Individuals representing all age classes were present on Ashmore Reef. Cow and calf pairs indicate that breeding occurs on the reef and there is at least some short-term residency. The oceanic coral reef habitat used by these dugongs is unusual when compared to the coastal habitat used by other Australian populations. Situated between Indonesia and the Australian mainland, Ashmore Reef supports a population of dugongs whose genetic identity is uncertain.

方法步驟描述:
- In November 1996, observations from a Coastwatch surveillance aircraft confirmed anecdotal reports by Parks Australia North personnel of dugongs on Ashmore Reef (Whiting 1999). Eight dugongs were sighted within the transect area which represented 6% (11 km 2) of the reef flat (182 km 2).
- In 1996, a database was established to record all dugong sightings at Ashmore Reef. Since 2000, Australian Customs Officers stationed at Ashmore Reef have recorded dugong sightings during their routine patrols.
