Candelariella reflexa

Unknown

Overview

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

Candelariella reflexa faces severe threats from air pollution and acid rain, which directly damage its delicate thallus structure and disrupt the chemical balance required for photosynthesis. Urban development and industrial activities have eliminated many of its traditional substrates, particularly the specific types of calcareous rocks and old mortar it requires. Climate change compounds these pressures by altering precipitation patterns and increasing temperature extremes that stress this pollution-sensitive lichen.

Threat summary

Habitat

This crustose lichen grows exclusively on calcareous substrates including limestone outcrops, old mortar, and concrete structures in urban and semi-urban environments. It requires specific chemical conditions and is particularly sensitive to air quality, thriving only in areas with minimal atmospheric pollution.
