Conservation and Management

Not globally threatened (Least Concern). The world population of Sharp-tailed Sandpiper (Calidris acuminata) has estimated at 160,000 birds (8) and at 85,000 birds (but with 95% confidence limits of 83,842 and 173,717;9) depending on the model used. There is no current evidence of an overall decline, though numbers at Coorong, South Australia — an important wintering site — have been reported as declining (93).

Effects of Human Activity

The greatest danger to the Sharp-tailed Sandpiper is habitat loss at migratory stops in Asia due to industrial development and water diversion along major tributaries (13). Hunting in China is also a threat, though a much lesser one (94, 13).

Management

Most of the world's population winters in Australia, especially southeastern Australia, where population densities are high; therefore, suitable management of coastal and inland wetlands in this region is essential for survival of the species. At Hunter Estuary, New South Wales, the opening of floodgates from 2008 to 2013 led to the formation of new tidal saltmarshes which were then heavily used by Sharp-tailed Sandpiper, with >1,000 birds present every Austral summer from 2011/2012 onwards and peak numbers of 7,000 to 8,000 birds during 2013/2014 and 2014/2015 (45). Additionally, an area in New South Wales that had previously hosted large numbers of shorebirds was then was overgrown by gray mangrove (Avicennia marina) due to human activity; the mangroves were cleared and shorebirds (including Sharp-tailed Sandpiper) returned in numbers to the newly formed mudflats (69).
