Habitat and Ecology [top]

Habitat and Ecology:This was a terrestrial species of lowland and montane tropical rainforests. It was a stream breeding species.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The decline in Ecuador is unexplained, and is possibly due to the disease chytridiomycosis, although this seems unusual given that the species was also found at lower elevations where chytridiomycosis is often not considered to be a threat. Other possible factors contributing to the extinction of this species include general climate change, pollution and habitat loss.

Conservation Actions [top]

Conservation Actions: The range of this species overlapped with the Reserva Ecológica Cotacachi-Cayapas and possibly reached the northern limit of the Reserva Ecológica Los Illinizas.
