Mac Clark (Acacia peuce) Conservation Reserve

Acacia peuce or waddywood is one of the rarest and most striking trees that grows in the Australian arid zone.

Found in only three locations worldwide, it survives at Mac Clark on a stony wind-swept plain where the average rainfall is 150mm.

The only other places it is found are Boulia and Birdsville in Queensland.

About 1,000 mature trees are protected here and some are fenced to protect them from cattle.

The site is subject to ongoing scientific research.

Waddywood is an extremely hard wood that was traditionally used to make digging tools by the local Aboriginal people. The trees can grow to be 17m tall and live up to 500 years.

You can not camp in the reserve, but you can camp at Old Andado Station.
