Scientific Name: Zamia purpurea Vovides, J.D.Rees & Vázq.Torres

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A4abcd ver 3.1
Year Published: 2010
Date Assessed: 2009-10-31
Assessor(s): Vovides, A., Chemnick, J. & Gregory, T.
Reviewer(s): Donaldson, J.S. & Bösenberg, J.D.
Justification:
Qualifies as at least Endangered due to an estimated decline of 50-70% over the past three generations and an estimated population size of 2,000 mature individuals. Ongoing decline is expected to exceed 80% over three generations so it has been assessed as Critically Endangered under criterion A4.
