Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Nepenthes dubia faces severe threats from habitat destruction due to mining activities and agricultural expansion in its limited montane range. The species' extremely restricted distribution on a few mountain peaks in Sumatra makes it particularly vulnerable to localized disturbances. Palm oil plantation development and infrastructure projects continue to fragment and destroy the remaining highland forest habitats where this carnivorous plant survives.

Threat summary

Nepenthes dubia inhabits upper montane forests and mossy cloud forests at elevations between 1,600-2,400 meters in the mountains of northern Sumatra. The species grows as an epiphyte or terrestrial plant in humid, cool conditions with consistent moisture from fog and rainfall.
