Knema retusa

Unknown

Overview

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

Knema retusa faces severe pressure from deforestation and habitat conversion throughout its Southeast Asian range. The species is particularly vulnerable to logging operations and agricultural expansion, as it depends on intact lowland and hill forest ecosystems. Palm oil plantations and urban development have fragmented remaining populations, while the species' slow growth rate and specific ecological requirements limit its ability to recover in degraded areas.

Threat summary

Habitat

Knema retusa inhabits primary and secondary lowland rainforests and hill forests up to 800 meters elevation across Southeast Asia. The species typically grows in well-drained soils along forest edges and in gaps within the forest canopy, requiring the humid microclimate conditions of intact forest ecosystems.
