Overview

Rinodina calcarea is a crustose lichen species that forms thin, grayish to whitish crusts on calcareous substrates. This inconspicuous lichen plays an important ecological role in nutrient cycling and soil formation processes, while also serving as a bioindicator of air quality in its specialized habitats.

Rinodina calcarea, a crustose lichen species, faces severe decline primarily due to habitat loss and degradation of its specialized calcareous substrates. Air pollution, particularly nitrogen deposition and acid rain, significantly impacts this pollution-sensitive species by altering the chemistry of its rocky habitats and reducing air quality.

Threat summary

Habitat

Rinodina calcarea grows exclusively on natural limestone outcrops, calcareous rocks, and occasionally on old mortar of historic stone buildings. It typically colonizes exposed to semi-shaded vertical or sloping surfaces where calcium carbonate is readily available.

Frequently asked questions

Why is kalkkrimmerlav classified as Critically Endangered?
kalkkrimmerlav 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. Rinodina calcarea, a crustose lichen species, faces severe decline primarily due to habitat loss and degradation of its specialized calcareous substrates. Air pollution, particularly nitrogen deposition and acid rain, significantly impacts this pollution-sensitive species by altering the chemistry of its rocky habitats and reducing air quality.
Where does kalkkrimmerlav live?
kalkkrimmerlav 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 kalkkrimmerlav?
The main threats to kalkkrimmerlav 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.
