Heppia adglutinata

Unknown

Overview

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

Heppia adglutinata faces severe threats from habitat degradation due to air pollution and acid rain, which alter the chemical composition of its substrate rocks and reduce lichen survival rates. Urban development and quarrying activities directly destroy the specialized limestone and calcareous rock surfaces this species requires. Climate change compounds these pressures by altering precipitation patterns and increasing temperature extremes that stress this sensitive lichen's physiological processes.

Threat summary

Habitat

This crustose lichen grows exclusively on calcareous rocks, limestone outcrops, and mortar of old walls in Mediterranean and temperate regions. It requires specific microclimate conditions with moderate humidity and limited direct sunlight, typically found in sheltered rock crevices and north-facing surfaces.

Frequently asked questions

Why is rosettheppia classified as Endangered?
rosettheppia is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Heppia adglutinata faces severe threats from habitat degradation due to air pollution and acid rain, which alter the chemical composition of its substrate rocks and reduce lichen survival rates. Urban development and quarrying activities directly destroy the specialized limestone and calcareous rock surfaces this species requires. Climate change compounds these pressures by altering precipitation patterns and increasing temperature extremes that stress this sensitive lichen's physiological processes.
Where does rosettheppia live?
rosettheppia 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 rosettheppia?
The main threats to rosettheppia 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.
