Scientific name: Hunter Valley Weeping Myall Woodland in the Sydney Basin Bioregion
Conservation status in NSW: Critically Endangered Ecological Community
Commonwealth status: Critically Endangered
Gazetted date: 19 Feb 2016

Hunter Valley Weeping Myall Woodland of the Sydney Basin bioregion typically has a dense to open tree canopy up to about 15 m tall, depending on disturbance and regrowth history. The most common tree is Acacia pendula (Weeping Myall), which may occur with Eucalyptus crebra (Narrow-leaved Ironbark), A. salicina (Cooba) and/or trees within the A. homalophylla - A. melvillei complex. Understorey shrubs may include Canthium buxifolium (Stiff Canthium), Dodonaea viscosa (Sticky Hopbush), Geijera parviflora (Wilga), Notelaea microphylla var. microphylla (Native Olive) and Senna zygophylla (Silver Cassia). However, these shrubs are absent from some stands. The groundcover varies from dense to sparse, and is comprised of grasses such as Austrodanthonia fulva (a wallaby grass) and Themeda australis (Kangaroo Grass), and low shrubs and herbs such as Chrysocephalum apiculatum (Common Everlasting), Einadia nutans subsp. nutans (Climbing Saltbush), Enchylaena tomentosa (Ruby Saltbush), Maireana microphylla (Eastern Cotton Bush) and Ptilotus semilanatus.


Hunter Valley Weeping Myall Woodland of the Sydney Basin bioregion is currently known from parts of the Muswellbrook and Singleton Local Government Areas, but may occur elsewhere in the bioregion. It may also occur in the Upper Hunter Local Government Area within the Brigalow Belt South bioregion, although its presence has not yet been confirmed there.

A section of the community which occurs in heavy, brown clay soil at Jerry's Plains in the Hunter Valley is also listed by the Commonwealth as Critically Endangered.

Habitat and ecology

  • This community is associated with heavy clay soils on depositional landforms in the south-western part of the Hunter River valley floor.
  • It is of conservation significance because it represents a disjunct coastal example of vegetation that is found principally on the western slopes of Great Dividing Range. Taxa such as Acacia pendula, A. homalopyhlla-A. melvillei complex, Geijera parviflora, Enchylaena tomentosa, Maireana microphylla and Ptilotus semilanatus are typical of the inland flora of southeastern Australia.
