Placynthium lismorense

Unknown

Overview

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

Placynthium lismorense faces severe threats from coastal development and infrastructure projects that destroy its specialized rocky shore habitats. Climate change poses an additional risk through sea level rise and increased storm intensity, which can alter the delicate moisture and salinity conditions this lichen requires. Air pollution from nearby urban areas and industrial activities further degrades the air quality essential for lichen survival.

Threat summary

Habitat

This lichen species inhabits exposed rocky shores and coastal cliffs, typically growing on calcareous rocks in the maritime spray zone. It requires specific moisture conditions from sea spray and salt-tolerant substrates found in narrow coastal margins.
