 "Cumberland Plain Woodland", of which around six per cent remains in isolated stands, was the first Australian ecological community to be assigned this status.The western portion of the Cumberland Plain mainly consists of sparsely populated, vast, rural grasslands with undulating hills and scenic vistas.The Sydney western suburbs of Mount Vernon, Kemps Creek, Orchard Hills, Luddenham, Mulgoa, Bringelly, Silverdale and Horsley Park, among others, lie in this agricultural countryside, adjacent to the footsteps of the Blue Mountains westwards of these country plains.
