Summary This large block of woodland supports strong populations of the vulnerable Painted Honeyeater and near threatened Diamond Firetail, irregular numbers of the endangered Swift Parrot and Regent Honeyeater and the near-threatened Bush Thick-knee, and good numbers of other declining woodland birds.

Site description This IBA is defined as the conservation areas of the the Pilliga woodlands and scrub between the towns of Pilliga, Baradine, Coonabarabran and Narrabri in inland NSW. The IBA takes in the the Community Conservation Areas zones 1-4 (i.e. including Conservation Areas and much of the State Forests), all conservation areas managed by NSW NPWS and two private blocks, and includes the nearby Warrumbungle NP. Additional contiguous woodland on private land may be worthy of inclusion within the IBA but there is insufficient supporting bird survey data. The nearby Brigalow Belt Nature Reserve, which supports Painted Honeyeaters, is also included, however other suitable habitta around Narrabri, including network of smaller remnants surrounding Narrabri (including Yarrie Lake, Killarney, Bobbiwaa and Moema State Forests) need further survey work before inclusion. The whole Pilliga is important for woodland birds including Diamond Firetail and Painted Honeyeater, mainly along creeks, and the Bush Thick-knee along forest edges, and includes the Baradine/Yearinan Creek in central Pilliga (Regent Honeyeater), the eastern Pilliga (Swift Parrot), a large area of southern Namoi River catchment and Castlereagh River catchment. The area has a warm-temperate climate and is dominated by Ironbark, Red Gum, Callitris and Box woodlands and forests with areas of scrub and heath, and is the largest tract of dry sclerophyll forest in NSW. Much of the areas has been logged and logging continues in some areas with high densities of White Cypress Pine Callitris glaucophylla and Narrow-leaved Ironbark Eucalyptus crebra but the Pilliga Nature Reserve has been unlogged since 1931. Some fuel-reduction fires are undertaken in the eastern Pilliga, and fuel-reduction grazing in the western Pilliga, but the whole area suffers from wild-fires.
