Isoglossa oreacanthoides

Declining

Overview

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

Isoglossa oreacanthoides faces severe pressure from agricultural expansion and livestock grazing in its montane habitat. The species' restricted range in the Eastern Arc Mountains makes it particularly vulnerable to habitat fragmentation and degradation. Climate change poses an additional threat as warming temperatures may force this montane specialist to higher elevations with increasingly limited suitable habitat.

Threat summary
