One of Australia’s rarest trees existing in only three locations across Australia, is the Acacia peuce, commonly known as the Waddy-wood, Waddy and waddi.

Endemic to Central Australia, the Waddy-wood (Acacia peuce) is on the western and eastern edges of the Simpson Desert, Andado Station (approximately 230 km south-east of Alice Springs) in the Northern Territory (NT); and Birdsville and Boulia in Queensland.

At Andado Station the Waddy-wood is protected in the Mac Clarke (Acacia peuce) Conservation Reserve, NT, a site just dedicated to the Acacia peuce.

At Andado and Birdsville, A. peuce populations are associated with shallow sand aprons overlaying clayey and gibber slopes and plains. The Boulia population is associated with palaeochannels of the Hamilton and Georgina Rivers (Maslin 2001).

There are some fine examples of the Waddy-wood at the Alice Springs Desert Park.
