Truncatellina linearis

UnknownDDEUDDEU

Overview

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

Truncatellina linearis faces severe population decline due to habitat destruction from agricultural intensification and urban development across its limited range. The species' dependence on specific microhabitat conditions in calcareous grasslands makes it extremely vulnerable to changes in land management practices. Climate change poses an additional threat through altered precipitation patterns that affect the moisture levels critical for this terrestrial gastropod's survival.

Threat summary

Habitat

This critically endangered land snail inhabits calcareous grasslands and limestone areas with specific moisture and vegetation requirements. It typically occurs in short, species-rich grasslands on chalk or limestone substrates where it feeds on decaying organic matter and microorganisms.

Frequently asked questions

Why is Truncatellina linearis classified as Critically Endangered?
Truncatellina linearis 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. Truncatellina linearis faces severe population decline due to habitat destruction from agricultural intensification and urban development across its limited range. The species' dependence on specific microhabitat conditions in calcareous grasslands makes it extremely vulnerable to changes in land management practices. Climate change poses an additional threat through altered precipitation patterns that affect the moisture levels critical for this terrestrial gastropod's survival.
Where does Truncatellina linearis live?
Truncatellina linearis 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 Truncatellina linearis?
The main threats to Truncatellina linearis are 8.1, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
