Nepenthes bicalcarata

Unknown

Overview

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

Nepenthes bicalcarata faces severe pressure from habitat destruction as Bornean peat swamp forests are cleared for oil palm plantations and logging operations. The species' specialized requirement for acidic, waterlogged conditions makes it particularly vulnerable to drainage and conversion of wetland habitats. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate water balance essential for peat swamp ecosystems.

Threat summary

Habitat

This carnivorous pitcher plant is endemic to the acidic peat swamp forests of Borneo, where it grows in permanently waterlogged conditions with pH levels between 3.5-4.5. It typically occurs in open areas within the swamp forest canopy and along forest edges where light penetration allows for optimal growth.
