Unknown

Overview

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

Barleria tetracantha faces significant pressure from agricultural expansion and urban development across its limited range in the Western Ghats of India. The species is particularly vulnerable to habitat fragmentation as its specialized rocky outcrop and scrubland habitats are converted for cultivation and infrastructure projects. Collection pressure for ornamental use has also contributed to population declines in accessible areas.
