Justicia niassensis

Declining

Overview

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

Justicia niassensis faces severe pressure from deforestation and agricultural expansion across its limited range in the Nias Island region of Indonesia. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Palm oil plantations and subsistence farming continue to encroach on the lowland and hill forests where this endemic plant occurs.
