Caloplaca conjungens

Unknown

Overview

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

Caloplaca conjungens faces severe threats from coastal development and infrastructure projects that destroy its specialized rocky shore habitats. Rising sea levels and increased storm intensity due to climate change pose additional risks by altering the precise tidal zone conditions this lichen requires. Air pollution from nearby urban areas may also compromise the species' ability to photosynthesize effectively in its already restricted range.

Threat summary

Habitat

This critically endangered lichen species inhabits specific rocky coastal environments, typically growing on maritime rocks and cliffs within the spray zone of temperate shorelines. It requires precise conditions where salt spray meets terrestrial substrates, making it highly vulnerable to coastal changes.
