Overview

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

Leptothorax gredleri faces significant pressure from habitat fragmentation and degradation of its specialized alpine and subalpine environments. Climate change poses an escalating threat as warming temperatures force this cold-adapted species to retreat to increasingly limited high-elevation refugia. Agricultural intensification and tourism development in mountain regions further reduce available nesting sites in rock crevices and under stones.

Threat summary

Habitat

This species inhabits alpine and subalpine environments, typically nesting in rock crevices, under stones, and in sparse vegetation at elevations above 1,500 meters. It shows a strong preference for cool, moist microhabitats within mountain grasslands and rocky slopes of the European Alps.
