|Scientific Name:||Macrozamia occidua D.L.Jones & P.I.Forst|
|Red List Category & Criteria:||Vulnerable D2 ver 3.1|
|Reviewer(s):||Donaldson, J.S. & Bösenberg, J.D.|
This species is assessed as Vulnerable (VU) under criterion D2 because it has a very small area of occupancy (the extent of occurrence is only 10 km²) and it is only known from three locations. If there was any evidence of decline, the species would qualify as Endangered under criterion B1+2. Based on the lower population size estimate , the species comes very close to qualifying for listing as VU under criterion D1.
