Rio Chingual Valley Treefrog

Hyloscirtus pantostictus

Declining

Overview

The Rio Chingual Valley tree frog is a species of frog in the family Hylidae found in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist montane forests, rivers, and heavily degraded former forests. Scientists have seen it between 1950 and 2700 meters above sea level.

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

Threat summary

Habitat

This species inhabits montane cloud forests and humid Andean slopes between 1,800-2,400 meters elevation in Colombia. It requires pristine forest streams and adjacent vegetation for breeding and foraging, making it highly sensitive to habitat fragmentation.
