Site details
Site description: Haul Round Island is a fairly large sand island with a few rocks and adjacent areas of rock and mangroves, located close to shore off the coast of Maningrida in Arnhemland. The IBA also includes a small island 2 km east of West Point which regularly supports hundreds of pairs of Roseate and Black-naped Terns. Chatto (2001) island refs S012 and S119 and waterbird nesting colony ref W031.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: Chatto (2001) made 8 counts of Haul Round Island and also found up to 5000 Bridled Terns, 100s of nesting Crested Terns and 10s of nesting Silver Gulls. A colony of 150-200 Pied Cormorants nests in the mangroves on a reef adjacent to the island (Chatto 2000). The colony is active every year but the Roseate Terns may nest on other islands some years. Chatto did not visit the adjacent small island but this was reported to 'regularly support low hundreds' of Black-naped and Roseate Terns (D. Bond pers.comm. in Chatto 2001).
Other site values: Arnhemland ALT. Traditionally-owned land.
