Overview

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

Trachyzelotes pedestris faces significant pressure from habitat degradation in its limited Scandinavian range, particularly from agricultural intensification and urban development that fragments its specialized ground-dwelling habitat. Climate change poses an additional threat as warming temperatures may alter the microhabitat conditions this cold-adapted spider requires. The species' restricted distribution makes it especially vulnerable to local extinctions from habitat modification.

Threat summary

Habitat

This ground spider inhabits dry, sandy soils and sparse vegetation in northern European environments, typically found in open grasslands, heathlands, and forest edges. It prefers areas with loose substrate where it can construct its characteristic ground-level retreats.
