Description

A dry vine scrub community of the Cumberland Plain, western Sydney. Canopy trees include Prickly Paperbark (Melaleuca styphelioides), Hickory Wattle (Acacia implexa) and Native Quince (Alectryon subcinereus). There are many rainforest species in the shrub layer, such as Mock Olive (Notolaea longifolia), Hairy Clerodendrum (Clerodendrum tomentosum) and Yellow Pittosporum (Pittosporum revolutum). The shrub layer combines with vines, such as Gum Vine (Aphanopetalum resinosum), Wonga Vine (Pandorea pandorana) and Slender Grape (Cayratia clematidea) to form dense thickets in sheltered locations. Contains many more species and other references should be consulted to identify these. This community is listed as Critically Endangered under the "Western Sydney Dry Rainforest and Moist Woodland on Shale" in the EPBC Act.

Distribution

Very restricted and occurs most commonly in the far southern section of the Cumberland Plain, in the Razorback Range near Picton. Outlying occurrences have been recorded at Grose Vale and Cattai. There are 338 hectares remaining intact, the majority of these occurring in the Wollondilly local government area, but occurring to a lesser extent in the Baulkham Hills, Camden, Hawkesbury, Parramatta and Ryde local government areas. A small remnant can be seen in Fairfield City Farm.

Habitat and ecology

  • Restricted to hilly country where it occurs on the sheltered lower slopes and in gullies.
  • Generally found at higher elevation, in areas receiving higher rainfall than much of the Cumberland Plain Woodland.
  • Occurs on clay soils derived from Wianamatta shale.
  • Rainforest plants within this vegetation are fire sensitive and dependent on the sheltered aspect and density of vegetation for protection.
  • Vine thickets in Western Sydney Dry Rainforest provide good habitat for birds and mammals.
  • Several species of plants (including Spartothamnella juncea and rare and threatened such as Marsdenia viridiflora) have their southern distribution limit within areas of Western Sydney Dry Rainforest.
