Summary The IBA provides non-breeding habitat for the critically endangered Orange-bellied Parrot, breeding habitat for the endangered Australasian Bittern, and supports populations of the near threatened Hooded Plover, the restricted-range Rufous Bristlebird and the biome-restricted Striated Fieldwren.
Site description The IBA extends along the coast from Green Point in South Australia to eastern Bridgewater Bay in Victoria. It includes the wetland along the drain to Green Point, Pick Swamp, Piccaninnie Ponds Conservation Park, a small parcel of private land to the north of Piccaninnie Ponds Conservation Park, and Discovery Bay Coastal Park east to the end of Discovery Bay (the remaining sections along Bridgewater Bay and Nelson Bay only support Rufous Bristlebirds amongst the key bird species). The most prominent ecological community in the IBA is coastal scrub, which is dominated in most places by emergent Moonah, and is otherwise comprised of medium-sized shrubs (e.g. Coast Wattle, Coast Beard-heath, Seaberry Saltbush and Coast Daisy-bush) above a ground cover of grasses, herbs and sedges. The IBA includes a long stretch of exposed sandy beaches and sand dunes. The IBA also includes the Glenelg River estuary, Long Swamp and other freshwater swamps, some small permanent freshwater lakes and pools, and some small patches of herb-rich eucalypt woodland. Piccaninnie Ponds contain clear water upwelling from limestone aquifers.
