Clubiona frisia

Unknown

Overview

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

Clubiona frisia faces severe habitat degradation due to coastal development and tourism infrastructure along North Sea coastlines. Rising sea levels and increased storm intensity threaten the species' specialized dune and saltmarsh habitats, while agricultural intensification has reduced suitable inland refugia. The spider's limited dispersal ability and highly fragmented population structure make recovery particularly challenging.

Threat summary

Habitat

This specialized spider inhabits coastal dune systems, saltmarshes, and sandy grasslands along the North Sea coast. It requires areas with sparse vegetation and specific microhabitat conditions found in transitional zones between marine and terrestrial environments.
