Scientific Name: Macrozamia pauli-guilielmi W.Hill & F.Muell.

Assessment Information [top]

Red List Category & Criteria: Endangered A2cd; C1 ver 3.1
Year Published: 2010
Date Assessed: 2009-10-31
Assessor(s): Bösenberg, J.D.
Reviewer(s): Donaldson, J.S. & Hilton-Taylor, C.
Justification:
This reassessment is based on information that was made available for the 2003 listing. It is listed as Endangered (EN) based on an estimated decline of >50% over the past 50 years (three generations is 120 years) primarily due to habitat destruction. Based on current population estimates and trends, this species also qualifies as EN under criterion C1.
