Site description
This IBA contains a 50 km length of coastal heathland east of Albany in south-west Australia. It is defined by the adjacent Albany Management Zone (AMZ) management units, which support Noisy Scrub-birds and Western Bristlebirds, comprising of the protected areas of Two Peoples Bay, Mount Manypeaks, Arpenteur and Bald Island Nature Reserves and Waychinicup National Park, and the adjacent unprotected land (bound to north and west by Crown and freehold land). It is located in a temperate coastal zone and supports dense low shrubland and heathlands. The landscape ranges from flat at the base of the larger mountains to steep on the upper slopes, including Bald Island. Numbers and locations of key birds are increasing through active management but are locally extirpated by occasional wild fires. The IBA also includes a series of coastal wetlands, comprising Moates Lake, Gardner Lake and Angove Lake, which together appear to support small numbers of Australasian Bittern. It also includes Coffin Island which supports large numbers of nesting seabirds.

Key biodiversity
The IBA is likely to support more than 1% of the world population of Great-winged Petrel nesting on Coffin Island (which is used by 'many thousands' of this species) and Bald Island, but precise numbers are not known (Department of Conservation and Land Management 1995; Johnstone & Storr 1998). Long-billed Black-Cockatoos are uncommon visitors in small numbers (A. Danks pers. comm. 2008; Atlas of Australian Birds database). Hooded Plovers are regularly observed at the eastern end of Nanarup Beach (max. 5) and at Norman's Beach, in south-west of Waychinicup NP (max. 5) (A. Bondin pers. comm.). Other species of interest that occur within the IBA include Peregrine Falcon and Square-tailed Kite (Department of Conservation and Land Management 1995) and Fairy Tern (Atlas of Australian Birds database).

Non-bird biodiversity: Significant terrestrial fauna species identified at this site include Gilbert's Potoroo (CR), Quokka (VU), Western Ringtail Possum (VU), Honey Possum (LR), Western Brush Wallaby (LR), Mardo (LR), and Quenda (LR). There are also numerous endemic and threatened flora species within the boundaries of the site.
