Hieracium steenhoffii

Local name: grängesbergsfibbla

Unknown

Overview

Grängesbergsfibbla (Hieracium steenhoffii) is a rare perennial hawkweed endemic to specific locations in central Sweden, characterized by its distinctive yellow composite flowers and deeply lobed basal leaves with whitish undersides. This specialized plant typically grows 20-40 cm tall and plays a crucial role in supporting local pollinator communities in its restricted mountain grassland habitat.

Hieracium steenhoffii is critically endangered due to its extremely limited distribution in a single location in Sweden, making it highly vulnerable to habitat disturbance and environmental changes. The species faces ongoing threats from mining activities, habitat degradation, and its naturally small population size which increases extinction risk from stochastic events.

Threat summary

Habitat

Grängesbergsfibbla occurs exclusively in nutrient-poor, calcareous mountain grasslands and rocky slopes at elevations between 200-400 meters in the Grängesberg area of Dalarna County, Sweden. The species requires well-drained soils with sparse vegetation cover maintained by traditional extensive grazing practices.
