Scientific Name: Nepenthes madagascariensis Poir.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2018
Date Assessed: 2014-11-30
Assessor(s): Clarke, C.M.
Reviewer(s): Cantley, R.
Contributor(s): Sarunday, C.
Justification:
Although there are significant threats to this species in the Taolagnaro area, most subpopulations of N. madagascariensis do not appear to be threatened at present. Accordingly, this species is assessed as LC here, but there is a need to monitor population trends on a regular basis, as the complete loss of the Taolagnaro populations could lead to a rapid change in the species' conservation status.
