ljus tassfibbla

Hieracium mallopodoides

Unknown

Overview

Ljus tassfibbla (Hieracium mallopodoides) is a rare perennial hawkweed species characterized by its distinctive pale yellow flower heads and deeply lobed, grayish-green basal leaves with woolly undersides. This specialized alpine plant plays a crucial role in high-elevation ecosystems by providing nectar for endemic pollinators and helping stabilize rocky substrates with its robust root system.

Hieracium mallopodoides faces severe threats primarily from habitat loss and degradation due to agricultural intensification and urban development in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to local environmental changes and human activities. Climate change may further exacerbate these pressures by altering the specific ecological conditions this specialized plant requires.

Threat summary

Habitat

This species is restricted to exposed limestone cliffs and rocky crevices in subalpine and alpine zones, typically occurring between 1,800-2,400 meters elevation. It requires well-drained calcareous soils and thrives in areas with high UV exposure but protection from strong winds, often found in south-facing rock faces and scree slopes.
