Scientific Name: Macrozamia cranei D.L.Jones & P.I.Forst.

Assessment Information [top]

Red List Category & Criteria: Endangered C1 ver 3.1
Year Published: 2010
Date Assessed: 2009-10-31
Assessor(s): Forster, P.
Reviewer(s): Donaldson, J.S.; Bösenberg, J.D.
Justification:
Occurs in a very restricted area, with an estimated population size of 2,139 plants and a decline of ca. 20% over two generations (120 years). Therefore qualifies as Endangered. Would qualify as Vulnerable on the basis of its restricted range and occurrence at fewer than ten locations.
