Ecnomiohyla rabborum

Local name: Rabb’s Fringe-limbed Treefrog

Declining

Overview

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

Ecnomiohyla rabborum faces severe threats from chytrid fungal disease (Batrachochytrium dendrobatidis), which has devastated amphibian populations throughout Central America. The species' restricted range in cloud forests makes it particularly vulnerable to habitat degradation from agricultural expansion and climate change-induced shifts in moisture patterns. Its specialized breeding requirements in tree holes and bromeliads are increasingly compromised by forest fragmentation and altered precipitation regimes.

Threat summary

Habitat

This species inhabits montane cloud forests at elevations between 1,200-2,400 meters in Costa Rica and Panama. It requires pristine forest canopy with abundant epiphytes, particularly bromeliads and tree holes that collect water for breeding.
