Assiminea pecos

Unknown

Overview

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

Assiminea pecos faces severe threats from water diversions and groundwater pumping that reduce spring flows in the Pecos River system. Agricultural development and urban expansion have altered the natural hydrology of its spring-fed habitats, while introduced species and water pollution from agricultural runoff further degrade the specialized aquatic environments this endemic snail requires.

Threat summary

Habitat

This endemic freshwater snail inhabits spring-fed pools and slow-flowing sections of the Pecos River system in Texas and New Mexico. It requires clean, well-oxygenated water with stable temperatures and specific mineral compositions found in natural spring environments.

Frequently asked questions

Why is Assiminea pecos classified as Endangered?
Assiminea pecos 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. Assiminea pecos faces severe threats from water diversions and groundwater pumping that reduce spring flows in the Pecos River system. Agricultural development and urban expansion have altered the natural hydrology of its spring-fed habitats, while introduced species and water pollution from agricultural runoff further degrade the specialized aquatic environments this endemic snail requires.
Where does Assiminea pecos live?
Assiminea pecos occurs in Mexico, and United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Assiminea pecos?
The main threats to Assiminea pecos 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.
