|Scientific Name:||Macrozamia longispina P.I.Forst. & D.L.Jones|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Reviewer(s):||Donaldson, J.S. & Bösenberg, J.D.|
Although the species has a small distribution (extent of occurrence is about 50 km² and the area of occupancy about 20 km²), it is listed as Near Threatened because the plants are copious, reproduce well, and the insect pollination mutualism is healthy. Two of the subpopulations are in conservation reserves. Almost qualifies for a threatened listing under criteria B1a+2a and D2.
