Marstonia agarhecta

Unknown

Overview

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

Marstonia agarhecta faces severe threats from groundwater depletion and contamination affecting the cave and spring systems it depends upon. Agricultural runoff and urban development in the surrounding watershed have degraded water quality, while excessive groundwater pumping has reduced flow rates in critical spring habitats. The species' extremely limited range makes it particularly vulnerable to localized environmental changes.

Threat summary

Habitat

This freshwater gastropod inhabits cave springs and associated groundwater-fed aquatic systems in limestone karst terrain. It requires clean, cool, oxygen-rich water with stable temperatures and consistent flow rates typical of pristine spring environments.

Why is Marstonia agarhecta classified as Endangered?
Marstonia agarhecta 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. Marstonia agarhecta faces severe threats from groundwater depletion and contamination affecting the cave and spring systems it depends upon. Agricultural runoff and urban development in the surrounding watershed have degraded water quality, while excessive groundwater pumping has reduced flow rates in critical spring habitats. The species' extremely limited range makes it particularly vulnerable to localized environmental changes.
Where does Marstonia agarhecta live?
Marstonia agarhecta occurs in United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
