Telmatobius fronteriensis

Declining

Overview

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

Telmatobius fronteriensis faces severe threats from habitat degradation due to mining activities and water pollution in its high-altitude aquatic environments. The species is particularly vulnerable to chytrid fungal disease, which has devastated Andean frog populations throughout its range. Climate change poses additional risks through altered precipitation patterns and temperature increases that affect the delicate water chemistry of its specialized habitat.

Threat summary
