Overview

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

Lecidea sarcogynoides faces severe threats from air pollution and acid deposition, which alter the chemical composition of its rock substrates and disrupt the delicate pH balance required for lichen survival. Climate change compounds these pressures through altered precipitation patterns and temperature fluctuations that affect the species' ability to photosynthesize and reproduce. The lichen's extremely restricted range makes it particularly vulnerable to local environmental changes, with habitat degradation from human activities further limiting available suitable substrates.

Threat summary

Habitat

This critically endangered lichen species occurs on specific rock substrates in montane environments, typically growing on siliceous rocks in areas with particular microclimate conditions. The species requires very specific chemical and physical conditions on rock surfaces, making it highly sensitive to environmental changes.

Frequently asked questions

Why is Lecidea sarcogynoides classified as Critically Endangered?
Lecidea sarcogynoides is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Lecidea sarcogynoides faces severe threats from air pollution and acid deposition, which alter the chemical composition of its rock substrates and disrupt the delicate pH balance required for lichen survival. Climate change compounds these pressures through altered precipitation patterns and temperature fluctuations that affect the species' ability to photosynthesize and reproduce. The lichen's extremely restricted range makes it particularly vulnerable to local environmental changes, with habitat degradation from human activities further limiting available suitable substrates.
Where does Lecidea sarcogynoides live?
Lecidea sarcogynoides 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 Lecidea sarcogynoides?
The main threats to Lecidea sarcogynoides 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.
