Oaxacan Yellow Treefrog

Megastomatohyla pellita

Declining

Overview

The Oaxacan yellow tree frog is a species of frog in the family Hylidae and is endemic to Mexico. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss.

Megastomatohyla pellita faces severe population decline primarily due to extensive deforestation and agricultural conversion throughout its limited range in Central America. The species is particularly vulnerable to habitat fragmentation as it requires continuous forest canopy for breeding and foraging. Chytrid fungal disease has also been documented affecting amphibian populations in the region, posing an additional threat to remaining populations.
