Description

Sun Valley Cabbage Gum Forest is dominated by Eucalyptus amplifolia (Cabbage Gum) with E. eugenioides (Thin-leaved Stringybark) as an associated tree. Native understorey species include Acacia parramattensis, Imperata cylindrica, Lomandra longifolia and Pteridium esculentum.

Distribution

Occurs in the Sun Valley in the Blue Mountains City Council local government area. About 15 hectares of the community remains, mostly in poor condition.

Habitat and ecology

  • Occurs on soils formed from diatremes (pipes of volcanic material) at Sun Valley. Other diatreme substrates in the area support different dominant tree species and do not have Eucalyptus amplifolia.
  • Before disturbance, this community originally formed tall open forest. Much has been cleared for timber and grazing and, although there is still good cover of remnant trees and regeneration is occurring, the trees remaining are often small and young (less than 20 years old) with few older trees. The ground vegetation has also been highly modified by grazing and other disturbance.
  • Disturbed remnants are still considered to form part of the community; these include areas where the vegetation - either ground vegetation, trees or both - would regenerate in response to assistance, such as where the natural soil and associated seedbank are still at least partially intact.
