Overview

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

Alzoniella iberopyrenaica faces severe threats from groundwater extraction and pollution in its limited karst spring habitats. The species' extremely restricted range makes it highly vulnerable to hydrological changes, with agricultural runoff and urban development potentially altering the delicate chemical balance of its spring environments. Climate change poses an additional risk through altered precipitation patterns that could affect groundwater levels and spring flow rates.

Threat summary

Habitat

This freshwater gastropod is endemic to karst spring systems in the Iberian Peninsula, inhabiting the specialized microhabitats of limestone springs and associated groundwater seepages. The species requires pristine water quality and stable hydrological conditions typical of undisturbed karst aquifer systems.

Frequently asked questions

Why is Alzoniella iberopyrenaica classified as Critically Endangered?
Alzoniella iberopyrenaica is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Alzoniella iberopyrenaica faces severe threats from groundwater extraction and pollution in its limited karst spring habitats. The species' extremely restricted range makes it highly vulnerable to hydrological changes, with agricultural runoff and urban development potentially altering the delicate chemical balance of its spring environments. Climate change poses an additional risk through altered precipitation patterns that could affect groundwater levels and spring flow rates.
Where does Alzoniella iberopyrenaica live?
Alzoniella iberopyrenaica occurs in Spain. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Alzoniella iberopyrenaica?
The main threats to Alzoniella iberopyrenaica 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.
