Davis Scrub Nature Reserve is a 13 hectare sub tropical jungle remnant of the Big Scrub. Situated at 170 metres above sea level on an undulating high rainfall plain near Alstonville, New South Wales, Australia.
The red-brown soil is derived from a basaltic flow from the nearby Mount Warning. Significant rainforest tree species include Moreton Bay Fig, Black Bean, White Booyong, Red Bean, and Purple Cherry. A large Moreton Bay Fig dominates the rainforest horizon.
