This recovery plan covers the MacDonnell Ranges cycad Macrozamia macdonnellii (F.Muell. ex Miq.) A.DC. (syn. Encephalartos macdonnellii F.Muell ex Miq.) which belongs to the family Zamiaceae. This species is classified as Vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
Macrozamia macdonnellii is endemic to the arid southern region of the Northern Territory of Australia. This cycad is almost wholly restricted to the MacDonnell Ranges Bioregion where it occurs up to 200 km east and west of Alice Springs. It is the only cycad occurring in central Australia, and is situated 1400 km from any other member of the genus.
This species is strongly associated with steep south-facing ridge slopes and protected gorges, gullies and river edges. It sometimes occurs on exposed slopes where highly flammable spinifex (Triodia spp.) grasses are abundant.
Known and potential threats include:
- loss of genetic variation
- pollinators and seed dispersers
- weed invasion
- climate change, and
- removal of seeds from the wild.
This plan outlines identified threats and the actions required to help maintain or eventually improve the conservation status of the species.
