7.1.2 Migratory Shorebirds The Gulf of Carpentaria is recognised as an extremely important area for seabirds and shorebirds, including many that are listed under the EPBC Act. The extensive intertidal mudflats of both the Limmen Bight and the McArthur River floodplains are among the most important areas for migratory shorebirds in the Northern Territory due to the high biomass in the extensive soft sediment habitats which provide an abundant food source (Chatto and Baker 2008). They are both listed Sites of Conservation Significance (SOCS). McArthur River SOCS Large concentrations of shorebirds (more than 5,000) have been counted near the mouth of the McArthur River, which is an important staging area for migratory birds (Environment Australia 2001). Chatto (2003) undertook targeted shorebird surveys along the coast of the Northern Territory. Within the survey ‘block’ that incorporates Bing Bong Port the five most abundant shorebird species were found to be: • Black-tailed Godwit (Limosa limosa); • Great Knot (Calidris tenuirostris); • Red-necked Stint (Calidris ruficollis); • Curlew Sandpiper (Calidris ferruginea); and • Bar-tailed Godwit (Limosa lapponica). Currently all these species are listed as Least Concern under the TWPC Act, however proposed changes to the list of threatened species recommend Great Knot and Curlew Sandpiper be listed as Vulnerable, and Bar-tailed Godwit as Endangered. Consultants acting on behalf of McArthur River Mine have undertaken migratory bird surveys and documented a significant increase in migratory shorebirds in the most recent survey in comparison with previous counts in 2008 and 2003 (EMS cited in Xstrata Zinc 2010). The surveys were noted to highlight “the importance of the Port McArthur area, east of Bing Bong, as a nationally and globally significant migratory bird staging area and indicated that the Bing Bong Port area is not used by a large number of birds” (Xstrata Zinc 2010). This conclusion concurs with our field surveys and habitat analysis. The port of Bing Bong lies on the westernmost extent of the McArthur River floodplain (see Figure 47). There is far less suitable habitat for shorebirds at this extreme – the intertidal zone being narrower and much sandier than the mudflats closer to the river mouth. Ground surveys around the port area yielded few shorebirds (in numbers and species), and the helicopter survey disturbed only two flocks of a few hundred birds in each, and these were more than ten kilometres from the port. Limmen Bight SOCS Limmen Bight SOCS is approximately 40km downstream of the MLA areas. Counts of more than 38,000 shorebirds have been recorded in the Limmen Bight (in a survey done at a time when a number of the migratory shorebird species would have already departed) with flocks in numerous, well spread sites (Chatto 2003). Internationally significant numbers of the following shorebirds have been recorded (NRETAS 2009): • Great Knot (Calidris canutus); • Black-tailed Godwit (Limosa limosa); • Red Knot (Calidris canutus); • Grey-tailed Tattler (Tringa brevipes); and • Black-winged Stilt (Himantopus himantopus). Currently all these species are listed as Least Concern under the TWPC Act, however proposed changes to the list of threatened species recommend Great Knot is listed as Vulnerable.
