Overview

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

Edwardsia ivelli faces severe threats from coastal development and habitat modification along its restricted range in southern England. The species' extremely limited distribution makes it particularly vulnerable to local disturbances, with intertidal habitat degradation from human activities posing the primary risk. Climate change-induced sea level rise and increased storm intensity threaten to alter the specific sediment conditions this sea anemone requires for survival.
