Description

A low woodland, often having dense stands of Paperbark trees Melaleuca decora along with other canopy trees, such as Parramatta Red Gum (Eucalyptus parramattensis subsp. parramattensis). The shrub layer is not well developed and is mostly made up of young paperbark trees. The ground layer has a diversity of plants that tolerate waterlogged conditions, such as Swamp Pennywort (Centella asiatica), Common Rush (Juncus usitatus) and Branched Goodenia (Goodenia paniculata). Contains many more species and other references should be consulted to identify these.

Distribution

Occurs in western Sydney in the Castlereagh and Holsworthy areas, on deposits from ancient river systems along today's intermittent creeklines, often in poorly drained depressions. There is now only 616 hectares remaining intact, which mainly occurs in the Hawkesbury, Liverpool and Penrith local government areas. Good examples can be seen at Windsor Downs Nature Reserve and Kemps Creek Nature Reserve.

Habitat and ecology

  • Highly adapted to seasonal fluctuations of wet and dry, with the heavy clay soils cracking during extended dry periods
  • Intergrades into Ironbark and Scribbly Gum woodland and is subject to periodic fires. Most species are able to quickly regenerate after fires from lignotubers and buds beneath the bark
