Overview

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

Frosted Orache faces severe decline due to coastal development and tourism infrastructure that destroys its specialized sandy beach and dune habitats. Sea level rise and increased storm intensity threaten remaining populations by eroding critical nesting beaches and altering sediment dynamics. Agricultural expansion and urban sprawl have eliminated many inland salt marsh refugia where the species historically persisted during adverse coastal conditions.

Threat summary

Habitat

Frosted Orache inhabits sandy beaches, coastal dunes, and salt marshes along temperate coastlines, particularly favoring areas with periodic disturbance and high salinity. The species requires well-drained sandy or gravelly soils with regular salt spray exposure and can tolerate extreme salinity levels that exclude most competing vegetation.
