Habitat and conservation

Pristimantis silverstonei is a nocturnal frog found on medium to high level vegetation in primary cloud forest at elevations of 1,700–2,250 m (5,580–7,380 ft) above sea level. Development is direct^[1] (i.e., there is no free-living larval stage^[5]).

A formerly common species, Pristimantis silverstonei has undergone a decline that took place in the mid–late 1990s and is possibly caused by chytridiomycosis. There are some indications that the populations might be recovering. Nevertheless, also habitat loss remains a threat. It occurs in two protected areas: Cerro El Inglés Natural Reserve and Tatamá National Natural Park. Its range is also close to the Farallones de Cali National Natural Park.^[1]
