Hieracium oligolepium

Local name: fåfjällig fibbla

Fåfjällig fibbla (Hieracium oligolepium) is a rare perennial hawkweed characterized by its distinctive sparse-scaled involucre and pale yellow flower heads that bloom in late summer. This specialized alpine plant forms small rosettes with deeply lobed leaves and plays a crucial role in high-altitude pollinator networks, supporting endemic butterfly and bee species in Scandinavian mountain ecosystems.

02Description

Species Profile

Fåfjällig fibbla (Hieracium oligolepium) is a rare perennial hawkweed characterized by its distinctive sparse-scaled involucre and pale yellow flower heads that bloom in late summer. This specialized alpine plant forms small rosettes with deeply lobed leaves and plays a crucial role in high-altitude pollinator networks, supporting endemic butterfly and bee species in Scandinavian mountain ecosystems.

Hieracium oligolepium faces severe threats from habitat loss due to agricultural intensification and urban development in its limited range. Climate change poses additional pressure through altered precipitation patterns and temperature shifts that affect its specialized alpine and subalpine habitat requirements.
