Enoplognatha oelandica

Unknown

Overview

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

Enoplognatha oelandica faces severe habitat loss due to agricultural intensification and abandonment of traditional grazing practices on Öland's alvar grasslands. The species' extremely limited range makes it particularly vulnerable to local disturbances, while climate change threatens the delicate moisture balance required for its specialized limestone grassland habitat. Coastal development and tourism infrastructure pose additional pressures on remaining suitable sites.

Threat summary

Habitat

This endemic spider inhabits the unique alvar limestone grasslands of Öland, Sweden, requiring areas with sparse vegetation, exposed limestone bedrock, and specific moisture conditions. The species is found in traditional grazing areas where thin soils over limestone create the specialized microhabitat conditions necessary for its survival.
