dotted lichen

Bacidia laurocerasi

Unknown

Overview

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

Granlundlav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Urban development and forest management practices that favor younger tree stands reduce the availability of suitable old-growth host trees. Climate change compounds these pressures by altering precipitation patterns and increasing temperature stress on both the lichen and its host trees.

Threat summary

Habitat

Granlundlav grows exclusively on the bark of old deciduous trees, particularly favoring mature specimens in humid, sheltered forest environments. This epiphytic lichen requires stable microclimatic conditions with consistent moisture levels and minimal air pollution.

Frequently asked questions

Why is dotted lichen classified as Vulnerable?
dotted lichen is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Granlundlav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Urban development and forest management practices that favor younger tree stands reduce the availability of suitable old-growth host trees. Climate change compounds these pressures by altering precipitation patterns and increasing temperature stress on both the lichen and its host trees.
Where does dotted lichen live?
dotted lichen occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to dotted lichen?
The main threats to dotted lichen are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
