Hieracium crassiceps

Unknown

Overview

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

Hieracium crassiceps faces severe population decline due to habitat degradation from agricultural intensification and urban development in its limited Scandinavian range. The species is particularly vulnerable to changes in traditional land management practices, as it depends on specific soil conditions and light regimes found in semi-natural grasslands. Climate change poses an additional threat by altering the delicate ecological balance of its specialized alpine and subalpine habitats.

Threat summary

Habitat

This endemic hawkweed species inhabits specialized alpine and subalpine grasslands, rocky slopes, and semi-natural meadows in Scandinavia. It requires well-drained, nutrient-poor soils and specific light conditions typically found in traditional pastoral landscapes between 200-800 meters elevation.
