The MacDonnell Ranges Cycad (Macrozamia macdonnellii) is a unique and ancient plant species endemic to central Australia.

Found exclusively in the MacDonnell Ranges of the Northern Territory and certainly in Standley Chasm if you are visiting there, this cycad is a living fossil, belonging to a group of plants that has existed for over 250 million years.

This cycad is characterised by its palm-like appearance, with a thick trunk and a crown of long, feather-like fronds. The plants are slow-growing and can live for several centuries, with some specimens estimated to be over 1,000 years old. The specimens here were seen alongside the path leading in to Staley Chasm

It is well-adapted to the harsh, arid environment of central Australia. It has evolved to withstand long periods of drought and extreme temperatures. The plant’s seeds are dispersed by animals, particularly birds and small mammals. It holds significant cultural importance for the Indigenous peoples of the region, who have used various parts of the plant for traditional purposes. However, the species faces several threats, including habitat loss, illegal collection, and climate change.

Conservation efforts are underway to protect this rare and ancient species. The cycad is listed as vulnerable under Australian environmental law, and measures have been implemented to safeguard its remaining populations.
