Overview

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

Pyramidula tetragona faces severe population declines due to habitat destruction from agricultural expansion and urban development across its range. The species' specialized habitat requirements and limited dispersal ability make it particularly vulnerable to fragmentation, while climate change is altering the moisture and temperature conditions essential for its survival.

Threat summary

Habitat

This species inhabits calcareous grasslands, rocky outcrops, and limestone pavements, typically in areas with thin soils and specific pH conditions. It is often found in semi-natural grasslands, quarries, and disturbed ground with exposed mineral soil between 0-800m elevation.
