Summary The IBA includes high-tide roosts and low-tide feeding areas for more than 1% of the world's Great Knots.
Site description This IBA is a stretch of muddy and sandy coast just east of Darwin, from the shorebird roost at Lee Point to the end of the muddy bay at Tree Point. The northern extent of the boundary is poorly defined and could extend to the northern boundary of the Shoal Bay Conservation Area or to Gunn Point (the end of the bay); this requires more fieldwork. The IBA extends inland to include the mangroves but not the terrestrial vegetation.
Key Biodiversity The IBA has supported up to 1313 near threatened Black-tailed Godwit (A. & S. Keates in litt. 2007). It also supports nationally important numbers of Greater Sand Plover (700-1500 in Nov 2006-Jan 2007) and high numbers of Terek Sandpiper (e.g. 337 at Tree Point on 5 Nov 2006) and a handful of Beach Stone-curlews (A. & S. Keates in litt. 2007). Other species recorded in the IBA or on adjacent wetlands and plains include Little Whimbrel, Little Tern, Chestnut Rail, Bush Stone-curlew, Varied Lorikeet, Yellow Chat, White-gaped Honeyeater, Australian Yellow White-eye, Australian Bustard and Red Goshawk (Chatto 2006; DEWHA 2008; Atlas of Australian Birds database).
