Sydney Turpentine-Ironbark Forest, Endangered forest ecosystem in Sydney Basin, Australia.
Sydney Turpentine-Ironbark Forest is a native woodland type found across the greater Sydney region of New South Wales, dominated by turpentine trees and ironbark eucalypts. Beneath the canopy, layers of native grasses, ferns, and flowering shrubs form a multi-layered woodland structure.
This forest type once covered large parts of the Sydney Basin before European settlement began in the late 18th century. Agriculture, logging, and urban growth have since reduced it to scattered fragments, most of which survive only inside protected reserves.
The forest takes its name from two tree species: the turpentine tree (Syncarpia glomulifera) and ironbark eucalypts, both known for their dense, resin-rich timber. Early settlers used this timber heavily for shipbuilding and construction, which is still part of how local people understand the history of the land.
Wallumatta Nature Reserve in North Ryde and Stewart Park in Marsfield both have marked walking trails where you can explore the woodland on foot. Sturdy footwear is a good idea, as some paths can be uneven and the ground may be slippery after rain.
The turpentine trees in this forest develop a thick, fibrous bark over their lifetime that acts as a natural barrier against fire. This trait has allowed individual trees to survive repeated bushfires across the decades, even in areas where much of the surrounding vegetation was lost.
