Overview

Geomitra tiarella is a species of air-breathing land snail, terrestrial pulmonate gastropod mollusks in the family Geomitridae.

Geomitra tiarella faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the Canary Islands. The species is particularly vulnerable to introduced predatory species and invasive plants that alter its native habitat structure. Climate change poses an additional threat through altered precipitation patterns that affect the humid microhabitats essential for this terrestrial gastropod's survival.

Threat summary

Habitat

This endemic land snail inhabits humid laurel forests and coastal scrublands in the Canary Islands, particularly favoring areas with dense vegetation cover and stable moisture levels. It requires specific microhabitat conditions including leaf litter, rotting wood, and rocky crevices that provide shelter and maintain the humidity essential for its survival.

Frequently asked questions

Why is Geomitra tiarella classified as Critically Endangered?
Geomitra tiarella 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. Geomitra tiarella faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the Canary Islands. The species is particularly vulnerable to introduced predatory species and invasive plants that alter its native habitat structure. Climate change poses an additional threat through altered precipitation patterns that affect the humid microhabitats essential for this terrestrial gastropod's survival.
Where does Geomitra tiarella live?
Geomitra tiarella occurs in Portugal. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Geomitra tiarella?
The main threats to Geomitra tiarella are 1.3, 4.1, 5.3, and 8.1. The full IUCN-classified threat record for this species is detailed on the species page.
