Plectocarpon scrobiculatae

Unknown

Overview

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

Plectocarpon scrobiculatae faces severe decline due to habitat degradation from atmospheric pollution and acid rain, which directly impacts the bark chemistry of its host trees. The species is particularly vulnerable to air quality changes in urban and industrial areas where it historically occurred. Climate change compounds these pressures by altering precipitation patterns and temperature regimes that affect both the lichen and its substrate trees.

Threat summary

Habitat

This crustose lichen species grows exclusively on the bark of mature deciduous trees, particularly favoring oak and ash species in old-growth and semi-natural woodland environments. It requires stable microclimatic conditions with consistent humidity levels and minimal air pollution exposure.
