Oaxacan Fringe-limbed Treefrog

Ecnomiohyla echinata

Unknown

Overview

Ecnomiohyla echinata is a species of frog in the family Hylidae. It is endemic to Sierra Juárez, Oaxaca, Mexico. Its natural habitat is cloud forest at around 2,000 m (6,600 ft) asl. It relies on humid habitats, in particular the vegetation along streams as well as epiphytic plants where it can find refuge. It breeds in streams. It is threatened by habitat loss and the spread of chytridiomycosis.

Ecnomiohyla echinata faces severe threats from habitat destruction due to deforestation, agricultural expansion, and urban development throughout its limited range in Central America. The species is particularly vulnerable due to its specialized habitat requirements and small population size, with additional pressures from climate change affecting montane forest ecosystems and potential disease outbreaks that have impacted amphibian populations across the region.

Threat summary

Why is Oaxacan Fringe-limbed Treefrog classified as Critically Endangered?
Oaxacan Fringe-limbed Treefrog is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Ecnomiohyla echinata faces severe threats from habitat destruction due to deforestation, agricultural expansion, and urban development throughout its limited range in Central America. The species is particularly vulnerable due to its specialized habitat requirements and small population size, with additional pressures from climate change affecting montane forest ecosystems and potential disease outbreaks that have impacted amphibian populations across the region.
Where does Oaxacan Fringe-limbed Treefrog live?
Oaxacan Fringe-limbed Treefrog occurs in Mexico. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
