The Sydney Sandstone Ridgetop Woodland is one of six main indigenous forest communities of Sydney, Australia found predominantly on ridgetops and slopes of the Hornsby Plateau, Woronora Plateau and the lower Blue Mountains area. It is an area of high biodiversity, existing on poor sandstone soils, with regular wildfires, and moderate rainfall.


The Ridgetop Woodland is a low eucalypt forest having a diverse sclerophyll shrub layer, mallees and open groundcover of sedges that sit on the Triassic Hawkesbury sandstone plateaux, which encircle the Sydney Basin. The community is found in areas 600m above sea level where the average annual rainfall ranges from 850mm to 1650mm. Around one-quarter of this community has been cleared for urban development, though many areas still remain in conservation reserves.
