Thunbergia austromontana

Declining

Overview

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

Thunbergia austromontana faces severe threats from habitat destruction due to agricultural expansion and human settlement in its restricted montane range. The species' extremely limited distribution makes it particularly vulnerable to localized disturbances, with small population fragments at risk of complete elimination from individual sites. Climate change poses an additional threat by altering the specific temperature and moisture conditions required by this high-altitude specialist.

Threat summary

Habitat
