moerasmolspin

Robertus arundineti

Unknown

Overview

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

The moerasmolspin faces severe habitat degradation due to wetland drainage and agricultural conversion of its specialized marsh environments. Water level fluctuations from climate change and human water management disrupt the delicate moisture conditions this species requires. Pollution from agricultural runoff and urban development further compromises the quality of remaining wetland habitats.

Threat summary

Habitat

This specialized spider inhabits reed beds, marshes, and other wetland vegetation where it constructs webs among tall grasses and sedges. It requires stable moisture levels and dense vegetation structure typical of undisturbed marsh ecosystems.

Frequently asked questions

Why is moerasmolspin classified as Endangered?
moerasmolspin 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 moerasmolspin faces severe habitat degradation due to wetland drainage and agricultural conversion of its specialized marsh environments. Water level fluctuations from climate change and human water management disrupt the delicate moisture conditions this species requires. Pollution from agricultural runoff and urban development further compromises the quality of remaining wetland habitats.
Where does moerasmolspin live?
moerasmolspin occurs in Åland Islands, Austria, Belgium, Bulgaria, Czechia, and Denmark (plus 26 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 moerasmolspin?
The main threats to moerasmolspin 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.
