Trigonectes strigabundus

Unknown

Overview

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

Trigonectes strigabundus faces severe threats from groundwater extraction and aquifer depletion, which directly impacts the water table levels essential for its subterranean habitat. Agricultural intensification and urban development in the surrounding landscape have altered natural drainage patterns and increased pollution inputs into the groundwater system. Climate change poses an additional threat through altered precipitation patterns that affect groundwater recharge rates in its limited range.
Threat summary

Habitat
