strandblocklav

Porpidia hydrophila

Unknown

Overview

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

Strandblocklav faces severe pressure from coastal development and infrastructure projects that destroy its specialized rocky shore habitats. Rising sea levels and increased storm intensity due to climate change threaten to submerge or alter the specific tidal zone conditions this lichen requires. Pollution from urban runoff and marine activities degrades water quality in coastal areas where the species occurs.

Threat summary

Habitat

Strandblocklav inhabits the splash zone of rocky coastlines, growing on granite and other hard rock surfaces that receive regular salt spray but remain above the high tide line. This specialized lichen requires the precise moisture and salinity conditions found in this narrow coastal transition zone.
