rietstrekspin

Tetragnatha striata

Unknown

Overview

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

The rietstrekspin faces severe habitat degradation due to wetland drainage and agricultural intensification across its limited European range. Water pollution from agricultural runoff and urban development has compromised the quality of remaining reed bed habitats essential for this specialized orb weaver. Climate change-induced alterations to wetland hydrology further threaten the delicate moisture conditions required for successful reproduction and prey availability.

Threat summary

Habitat

This specialized orb weaver spider inhabits reed beds and wetland margins, constructing its webs among tall grasses and emergent vegetation in freshwater marshes. The species requires stable water levels and dense vegetation structure typical of undisturbed wetland ecosystems.

Frequently asked questions

Why is rietstrekspin classified as Endangered?
rietstrekspin is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The rietstrekspin faces severe habitat degradation due to wetland drainage and agricultural intensification across its limited European range. Water pollution from agricultural runoff and urban development has compromised the quality of remaining reed bed habitats essential for this specialized orb weaver. Climate change-induced alterations to wetland hydrology further threaten the delicate moisture conditions required for successful reproduction and prey availability.
Where does rietstrekspin live?
rietstrekspin occurs in Åland Islands, Austria, Belgium, Denmark, Estonia, and Finland (plus 18 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 rietstrekspin?
The main threats to rietstrekspin 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.
