Trichadenia zeylanica

Unknown

Overview

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

Trichadenia zeylanica faces severe pressure from rapid deforestation and agricultural expansion across its limited range in Sri Lanka's lowland wet zone. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Urban development and infrastructure projects continue to encroach on its remaining habitat, while invasive plant species alter the understory composition of its forest environment.
