This type of vegetation thrives on Ku-ring-gai's sandy geology, with diverse species such as the Scrub She-oak, Heath-leaved Banksia and Dwarf Oak adapted to the dry conditions.
Sydney Sandstone Gully Forest
This forest also thrives on Ku-ring-gai's geology of Hawkesbury Sandstone and is common in gullies and on sheltered slopes. Forest species include the Smooth-barked Apple, Red Bloodwood, Sydney Peppermint, Blackbutt, Sunshine Wattle and Old Man Banksia.
Sydney Sandstone Ridgetop Woodland

This community has a lot of variation, from open forest to heathland, and includes species such as the Narrow-leafed Apple, Scribbly Gum, Sydney Peppermint, Stringybark, Wattle and Flannel Flower, which provide food and habitat for many threatened animals, such as the Glossy Black Cockatoo and Powerful Owl.
