Population [top]

Population: In Costa Rica, this species is uncommon (Puschendorf et al. 2006), but believed to be moderately abundant and stable (G. Chaves pers. comm. 2015). Lips (1998) reported a sharp decline at Las Tablas (Costa Rica), but populations have persisted at Monteverde (Costa Rica) (Pounds et al. 1997). Further information is needed on the status of the species' populations in Panama.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It inhabits relatively undisturbed, dense, primary humid montane forest. Breeding takes place by direct development.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): In Panama, the major threat is logging. In Costa Rica threats to the species are unknown (G. Chaves pers. comm. 2015). The cause of the decline at Las Tablas has not been determined, but chytridiomycosis may be involved, as it was detected in this species at this location (Lips et al. 2003). It persists at Monteverde where chytrid has also been recorded (Pounds et al. 1997). More recently, chytrid was not detected in frogs (n=4) collected along an altitudinal transect in Costa Rica (Puschendorf et al. 2006).

Conservation Actions [top]

Conservation Actions: Conservation Actions 
It has been recorded from a number of protected areas in Costa Rica (including Parque Nacional Braulio Carrillo, and Parque Internacional La Amistad) and Panama (Parque Nacional Chagres and Parque Nacional Volcán Barú).
Research Needed
Studies are required to improve the understanding of the taxonomic relationship between this species and Pristimantis cruentus, so as to aid in the correct identification of populations (G. Chaves pers. comm. 2015).
