Pilosella dimorphoides
Local name: grenmarsvæve
Overview
Grenmarsvæve (Pilosella dimorphoides) is a distinctive hawkweed species characterized by its dimorphic leaf structure, featuring both basal rosette leaves and reduced stem leaves with dense stellate hairs. This perennial herb plays a crucial role in specialized grassland ecosystems, providing nectar for rare pollinating insects and serving as a host plant for several endemic invertebrate species.
Pilosella dimorphoides faces severe population decline primarily due to habitat loss from agricultural expansion and urban development in its limited range. Climate change and invasive species competition further threaten the remaining fragmented populations of this endemic hawkweed species.
Habitat
Grenmarsvæve occurs in nutrient-poor calcareous grasslands and rocky slopes at elevations between 200-800 meters, typically in areas with shallow soils over limestone bedrock. It requires sites with specific moisture regimes - well-drained but not drought-stressed - often found along transitional zones between dry meadows and scrubland margins.
