ABBOT POINT CUMULATIVE IMPACT ASSESSMENT REPORT 9 Migratory shorebirds and the Australian Painted Snipe This chapter provides a detailed assessment of the presence and potential impacts of development on the thirty-six EPBC Act listed migratory shorebirds and the Australian Painted Snipe (listed as a vulnerable threatened species). These species have been grouped together in the report to aid the impact assessment process as they have similar habitat requirements and will be subject to a common set of issues around potential impacts, mitigation, conservation objectives and offsets. 9.1 BACKGROUND TO MIGRATORY SHOREBIRDS Thirty-six migratory shorebird species use the East Asian-Australasian flyway. Each year these birds breed in the northern hemisphere and migrate south to Australia and New Zealand where they feed intensively, building up energy reserves to fuel their northern migration and breeding (Clemens et al. 2008). 9.1.1 Assessing migratory shorebirds under the EPBC Act As discussed in Part B of this report, potential impacts for migratory shorebirds have been considered within the context of two key concepts commonly applied under the EPBC Act for migratory species (DEWHA 2009): • important habitat; and • an ecologically significant proportion of the population. Where neither of these two features of a migratory species is present, impacts are generally not considered an issue under the EPBC Act (DEWHA 2009a). In addition to this broad guidance, the Commonwealth Government has also issued a set of specific guidelines (DEWHA 2009a) for assessing the importance of habitat for migratory shorebird species in Australia. These guidelines (referred to as EPBC Act policy statement 3.21) outline a set of criteria for identifying ‘important habitat’. The associated background paper (DEWHA 2009b) that accompanies the policy statement provides detailed recommendations about survey requirements for migratory shorebirds. Under the guidelines (DEWHA 2009a), important habitat for migratory shorebirds (excluding Latham’s Snipe) includes sites that support: • at least 0.1 per cent of the flyway population of a single species; • at least 2,000 migratory shorebirds; or • at least 15 migratory shorebird species.
