Garcialebias nigrofasciatus

Unknown

Overview

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

Garcialebias nigrofasciatus faces severe threats from habitat destruction as temporary pools and wetlands in its restricted range are drained for agricultural expansion and urban development. The species' dependence on seasonal water bodies makes it extremely vulnerable to altered precipitation patterns and extended drought periods. Water pollution from agricultural runoff and livestock contamination further degrades the quality of remaining breeding habitats.
Threat summary
