Description

The Weeping Myall Woodlands occur in a range from open woodlands to woodlands, generally 4-12 m high, in which Weeping Myall (Acacia pendula) trees are the sole or dominant overstorey species. Other common names for Weeping Myall include Myall, Boree, Balaar, Nilyah, Bastard Gidgee, and Silver Leaf Boree. Species assemblage Weeping Myall trees often occur in monotypic stands, however other vegetation may also occur in the ecological community, though not as dominant species. These include: Western Rosewood (Alectryon oleifolius subsp. elongatus); Poplar Box (Eucalyptus populnea); or Black Box (Eucalyptus largiflorens) (NSW Scientific Committee 2005; Keith 2004). Grey Mistletoe (Amyema quandang) commonly occurs on the branches of Weeping Myall trees throughout the ecological community’s range (NSW Scientific Committee 2005). Other species commonly present in the community are listed in Appendix 1. Weeping Myall goes through regular cycles of senescence (aging and death) and regeneration. Weeping Myall trees are also susceptible to defoliation by Bag-shelter Moth (Ochrogaster lunifer) caterpillars and are often lopped for domestic stock fodder. Therefore, the ecological community can be dominated by Weeping Myall trees that are in a living, defoliated or dead state. The understorey of Weeping Myall Woodlands often includes an open layer of shrubs above an open ground layer of grasses and herbs, though the ecological community can exist naturally either as a shrubby or a grassy woodland (Beadle 1948; Keith 2004). In many areas, however, the shrub layer has disappeared through overgrazing and dieback events and the woodland now has a primarily grassy understorey (Beadle 1948). The ground layer includes a diversity of grasses and forbs, and varies in species composition and cover depending on past and current grazing regimes, and the occurrence of recent rain (NSW Scientific Committee 2005). In the southern part of the distribution of Weeping Myall Woodlands (south of the midLachlan region), chenopods, such as saltbushes, native cotton bushes, bluebushes, goosefoots and copperburrs, were originally an important component of the understorey. As chenopods are generally highly palatable, they have largely disappeared in areas that have been grazed by stock and/or feral animals for substantial periods of time. In the northern parts of the ecological community, chenopod shrubs are a less prominent component of the understorey (NSW Scientific Committee 2005; White et al. 2002). Additionally, in the northern part of the distribution winter-growing grasses, such as Wallaby Grasses (Austrodanthonia spp.), are less common, while summer-growing grasses, such as Mitchell Grass (Astrebla spp.) and Queensland Blue Grass (Dichanthium sericeum), are more abundant, than in the south (Benson 2006, White et al. 2002). The Weeping Myall Woodlands also provide important habitat for a range of animals such as the Superb Parrot (Polytelis swainsonii), Painted Honeyeater (Grantiella picta) and the Bush Stone-curlew (Burhinus grallarius). In order to meet the definition of the TEC sites must satisfy condition criteria stipulated in the Listing Advice and/or Conservation Advice. Typically condition is assessed by reference to patch size and vegetation structure thresholds or species composition metrics.
