Hypericum hartwegii

Unknown

Overview

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

Hypericum hartwegii faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its limited montane range. The species' extremely restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented across isolated mountain slopes. Climate change poses an additional threat by altering the specific temperature and moisture conditions required for this high-altitude specialist.

Threat summary
