Habitat and conservation

edit

Osornophryne sumacoensis inhabits the cloud forest surrounding the lake, at 2,500–2,800 m (8,200–9,200 ft) asl. The forest is dominated by bamboo (Chusquea sp.), Ficus, and other trees up to 20 m (66 ft) tall.[1][3]

The species lives within the Sumaco Napo-Galeras National Park. Volcanic eruption is a threat to this species restricted to a single location.[1]
