Bactrospora corticola

Local name: liten sönderfallslav

Unknown

Overview

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

Bactrospora corticola faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter bark chemistry and disrupt the delicate chemical balance required for lichen survival. Old-growth forest fragmentation eliminates the stable, humid microhabitats this species requires, while climate change-induced shifts in precipitation patterns threaten the consistent moisture levels essential for its reproductive cycles. The species' extremely slow growth rate and limited dispersal ability make recovery from population losses exceptionally difficult.
Threat summary

Habitat

This crustose lichen grows exclusively on the bark of old deciduous trees, particularly favoring smooth-barked species in humid, undisturbed forest environments. It requires stable microclimatic conditions with consistent moisture levels and minimal air pollution, typically found in ancient woodland remnants and mature forest reserves.
