Neriene hammeni

Unknown

Overview

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

Van der Hammen's hangmat spider faces severe threats from urban development and agricultural expansion across its limited range in the Netherlands and Belgium. The species' specialized habitat requirements for undisturbed grasslands and heathlands make it particularly vulnerable to land-use changes. Climate change poses additional pressure through altered precipitation patterns that affect the microhabitat conditions essential for web construction and prey availability.

Threat summary

Habitat

This species inhabits undisturbed grasslands, heathlands, and moorland edges with specific microclimate requirements. It constructs its characteristic sheet webs in low vegetation, particularly favoring areas with stable moisture levels and minimal human disturbance.
