Parjacti Treefrog

Hyloscirtus chlorosteus

Declining

Overview

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

Hyloscirtus chlorosteus faces severe population decline primarily due to habitat destruction from agricultural expansion and logging activities in Colombia's cloud forests. The species is particularly vulnerable to chytrid fungal infections, which have devastated amphibian populations throughout the Andean region. Climate change poses an additional threat by altering the temperature and humidity conditions essential for this species' survival in high-altitude environments.

Threat summary

Habitat

This species inhabits cloud forests and montane rainforests at elevations between 1,800-2,400 meters in the Colombian Andes. It requires pristine forest streams with clean, well-oxygenated water for breeding and is typically found near rocky cascades and waterfalls within primary forest habitat.
