Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2008-01-01
Assessor/s: Frank Solís, Roberto Ibáñez, Gerardo Chaves, Jay Savage, César Jaramillo, Brain Kubiki, Federico Bolaños
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern since, although its Extent of Occurrence is less than 20,000 km2, it is common and adaptable with a presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species occurs primarily in the humid, lower montane zone of the Cordillera de Tilarán, Cordillera Central, and Cordillera de Talamanca of Costa Rica and the Pacific slope of western Panama, but marginally in humid areas of the premontane zone, from 1,120-2,340m asl (Savage, 2002).

Population [top]

Population: In general, it is a very common species. In Panama, this species is presumed to have undergone some declines in the Reserva Forestal Fortuna. Although this species declined at one point at Monteverde and Cascajal, Costa Rica, populations have since recovered at Monteverde, and this species remains commonly encountered within Costa Rica.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It is a largely nocturnal tree frog of humid montane forest. It can be found in trees in pastures and similar open areas; it is commonly found in puddles on roads (Federico Bolaños pers. comm.). The species is an explosive small pond breeder; reproduction follows heavy rains, eggs are laid in small masses in the water.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Generally, it is threatened by habitat loss through the destruction of natural forests. While museum specimens of this species have been found to have the chytrid fungi, the current impact of this pathogen on the species is not known.

Conservation Actions [top]

Conservation Actions: Although there are no specific conservation measures in place, the species has been recorded from a number of protected areas in Costa Rica and a single protected area in Panama.
