Blastenia coralliza

Unknown

Overview

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

Blastenia coralliza faces severe threats from air pollution and acid rain, which directly damage its thallus and disrupt the delicate chemical balance required for photosynthesis. Urban development and industrial activities have eliminated much of its suitable habitat, while climate change is altering the specific atmospheric conditions this sensitive lichen requires for survival.

Threat summary

Habitat

This crustose lichen grows on the bark of deciduous trees and occasionally on calcareous rocks in areas with specific air quality requirements. It typically occurs in semi-natural woodlands, old parks, and historically less polluted urban environments where suitable host trees and atmospheric conditions persist.
