smalpalpedderkopp

Leptorhoptrum robustum

Unknown

Overview

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

Leptorhoptrum robustum faces significant pressure from habitat degradation in its specialized cave and underground environments. Agricultural intensification and urban development in surrounding areas alter groundwater flow patterns and introduce pollutants that contaminate the delicate subterranean ecosystems this spider depends upon. Climate change poses additional risks through altered precipitation patterns that affect cave humidity levels critical for the species' survival.

Threat summary

Habitat

This species inhabits specialized subterranean environments including limestone caves, underground chambers, and associated groundwater systems. It requires stable humidity levels and specific microclimate conditions found in these protected underground habitats.

Why is smalpalpedderkopp classified as Vulnerable?
smalpalpedderkopp is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Leptorhoptrum robustum faces significant pressure from habitat degradation in its specialized cave and underground environments. Agricultural intensification and urban development in surrounding areas alter groundwater flow patterns and introduce pollutants that contaminate the delicate subterranean ecosystems this spider depends upon. Climate change poses additional risks through altered precipitation patterns that affect cave humidity levels critical for the species' survival.
Where does smalpalpedderkopp live?
smalpalpedderkopp occurs in Austria, Belgium, Bulgaria, Denmark, Faroe Islands, and Finland (plus 14 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to smalpalpedderkopp?
The main threats to smalpalpedderkopp are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
