Overview

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

Acrocordia gemmata faces significant pressure from coastal development and infrastructure expansion along its rocky shore habitats. Marine pollution, particularly from agricultural runoff and urban discharge, degrades the water quality essential for this lichen's survival. Climate change-induced sea level rise and increased storm intensity threaten to alter the specific tidal zone conditions this species requires.

Threat summary

Habitat

This marine lichen inhabits rocky intertidal zones and coastal cliffs, typically growing on exposed granite and limestone surfaces within the spray zone. It requires specific moisture conditions from sea spray and fog, thriving in areas with consistent but not excessive salt exposure.
