Overview

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

Twisted Whitlowgrass faces severe population decline due to habitat destruction from coastal development and infrastructure projects along its specialized rocky shoreline environments. Climate change poses an additional threat through rising sea levels and increased storm intensity, which directly impact the species' narrow coastal habitat zones. Agricultural expansion and quarrying activities have further reduced available habitat, while the species' extremely limited distribution makes it particularly vulnerable to localized disturbances.

Threat summary

Habitat

Twisted Whitlowgrass inhabits rocky coastal cliffs, limestone outcrops, and gravelly shorelines in arctic and subarctic regions. The species requires well-drained, calcareous soils and is typically found in exposed, windswept locations along coastlines and on rocky slopes.
