Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Pale St John's-wort faces severe population declines due to habitat loss from agricultural intensification, woodland clearance, and urban development pressures on its specialized calcareous woodland habitats. The species' restricted distribution and specific ecological requirements make remaining populations highly vulnerable to environmental changes and fragmentation.
Key Facts
Habitat & Distribution
Occupies calcareous woodlands, chalk downs, and limestone grasslands, typically in partially shaded areas along woodland edges, clearings, and scrubland on alkaline soils. Prefers well-drained calcareous substrates in deciduous and mixed woodlands at low to moderate elevations.
