Hieracium serratoellipticum

Unknown

Overview

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

Timmersågsfibbla faces severe threats from habitat degradation and fragmentation in its specialized alpine and subalpine environments. Climate change poses an additional critical risk by altering the temperature and moisture conditions essential for this species' survival in high-elevation ecosystems. The species' extremely limited distribution and small population size make it particularly vulnerable to local extinctions.

Threat summary
