AUSTRALIA’S LONELIEST TREE – THE WADDI

Occurring in isolated populations on the fringe of the Simpson Desert in inland Australia, the Waddy tree (Acacia peuce), is one of the country’s rarest trees. This ancient tree with an estimated lifespan of up to 500 years, is slow growing and relies on rare and exceptionally high rainfall events to germinate and establish seedlings. The Waddy tree is now restricted to isolated populations in Queensland.

Often being the only tree species in their harsh and arid environment, the Waddy tree provides protection to other plant species and habitat for the numerous animal species in the region 

The timber of the Waddy tree is extremely hard and dense, with a dark red heartwood that was used for weapons and tools by our first nations people and as durable, termite-resistant fence posts and building material by early pastoralists. 

With the small populations of Waddy trees under pressure from wildfires, weeds, pests and even tourist traffic there is a need for further understanding of this species and to ensure the populations are protected from key threatening processes. 

DCQ will be seeking to ensure these populations remain viable, through management of pests, primarily rabbits, weeds, and livestock grazing . In addition to managing threats to the Waddy tree, expanding the research and knowledge base of this species through collaborations with government, universities, first nations people, councils and particularly landholders will be critical in ensuring the future of this species.
