brunspetsad fibbla
Hieracium acrogymnon
The brunspetsad fibbla (Hieracium acrogymnon) is a rare alpine hawkweed species characterized by its distinctive bronze-tinted leaves and compact yellow flower heads that bloom in late summer. This perennial herb plays a crucial role in high-altitude ecosystems by providing nectar for specialized alpine pollinators and helping stabilize rocky soil substrates with its deep taproot system.

Species Profile
The brunspetsad fibbla (Hieracium acrogymnon) is a rare alpine hawkweed species characterized by its distinctive bronze-tinted leaves and compact yellow flower heads that bloom in late summer. This perennial herb plays a crucial role in high-altitude ecosystems by providing nectar for specialized alpine pollinators and helping stabilize rocky soil substrates with its deep taproot system.
Climate change poses the primary threat to this species as warming temperatures force it to retreat to increasingly limited high-elevation refugia. Additional pressures include trampling from recreational activities in alpine areas and competition from invasive plant species that are expanding their range upward due to changing climatic conditions.
Key Facts
Habitat & Distribution
This species inhabits exposed rocky ledges and scree slopes at elevations between 2,200-3,100 meters in alpine zones. It typically grows in well-drained, mineral-rich soils among granite outcrops and talus fields where snow persists well into the growing season.
Threats
