Overview

Nymphargus cochranae is a species of frog in the family Centrolenidae. It is found in the lower Amazonian slopes of the Cordillera Occidental of Ecuador and adjacent Colombia, though the Colombian records require confirmation.

Nymphargus cochranae faces significant threats from habitat destruction due to deforestation, agricultural expansion, and urban development within its limited range in the Colombian Andes. The species is particularly vulnerable to climate change impacts on montane cloud forest ecosystems, while pollution from agricultural runoff and mining activities degrades the pristine stream habitats essential for its reproduction.

Threat summary

Habitat

This species inhabits montane cloud forests and adjacent stream environments in the Colombian Andes, typically found along rocky streams and rivers with clean, fast-flowing water between 1,500-2,500m elevation. It requires pristine riparian vegetation and is closely associated with moss-covered rocks and overhanging vegetation near permanent water sources.
