An outback sanctuary for one of Australia's rarest and oldest trees.
Mac Clark (Acacia peuce) Conservation Reserve
Mac Clark (Acacia peuce) Conservation Reserve is a small, highly specialised protected area in the Northern Territory of Australia, located in the remote locality of Ghan on the western edge of the Simpson Desert. Despite covering only around 30 square kilometers, it has national conservation significance because it protects the largest known stand of the rare and slow-growing Acacia peuce, also called waddywood, a tree species capable of reaching great age and stature in one of the harshest landscapes on the continent.
The reserve sits in a flat, stony, windswept plain where summer temperatures frequently rise above 40 degrees Celsius and annual rainfall is very low, an environment where ordinary shrubs and grasses struggle to survive. Within this rigorous setting, the reserve forms a fenced refuge that shields ancient waddywood trees, their seedlings, and the surrounding arid ecosystem from grazing livestock, rabbits, and other threats.
Established in 1982 and named after the pastoralist who championed its protection, the reserve also carries deep cultural importance as part of the traditional country of the Arrente people, whose long history of movement, tool-making, and land use is reflected in the artefacts still found across the area. It represents a rare convergence of botanical rarity, arid-land ecology, and outback heritage in central Australia.
