Scientific Name: Nepenthes adnata

Assessment Information [top]

Red List Category & Criteria: Endangered D ver 3.1
Year Published: 2014
Date Assessed: 2013-12-14
Assessor(s): Hernawati, N. & Clarke, C.M.
Reviewer(s): Cantley, R.
Contributor(s): Lee, C. & Sarunday, C.
Justification:
Nepenthes adnata has a restricted geographical range in the Tjampo Mountains of West Sumatra, Indonesia. Although the known population is relatively small (200 mature individuals), the majority of plants appear to be relatively free of direct threats at present. However, due to its small population size, land clearing, fire and over-collection of wild plants could all become serious threatening processes in future. The species is listed as Endangered based on its small population size.
History:
2000 Data Deficient

Population [top]

Population: At present, the known population of Nepenthes adnata is very small - only 200 mature individuals are known. It is not yet known whether current estimates are accurate, or whether the inconspicuous nature of the plant, coupled with the very rugged terrain that it grows in, obscure the actual number of mature individuals.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Nepenthes adnata grows terrestrially on mossy sandstone cliffs amongst dense vegetation. This region is characterized by very rugged terrain and few mountains and valleys have been explored to date. As this species is inconspicuous, and it habitats very difficult to reach, comparatively little is known about its ecology at present.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: Nepenthes adnata has no known uses and is of limited appeal to horticulturists. Its diminutive stature makes it popular among enthusiasts of Nepenthes, but trade in this species appears to be insignificant.

Threats [top]

Major Threat(s): Although the present threats to Nepenthes adanta (small-holder farming, increased fire frequency, and collection) do not appear to be significant, the survival of this species could be at risk if there is any increase in the probability or intensity of these threats.

Conservation Actions [top]

Conservation Actions: Nepenthes adnata is not subject to any species-specific conservation actions. Part of the range is in a forest reserve and it is listed on CITES Appendix II.
