Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Centrolenidae

Scientific Name: Centrolene peristictum
Species Authority: (Lynch and Duellman, 1973)

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii,iv,v)+2ab(iii,iv,v) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
Needs updating
Assessor(s): Luis A. Coloma, Santiago Ron, John Lynch, Diego Cisneros-Heredia, Erik Wild
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Vulnerable because its Area of Occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat, the number of locations, and the number of mature individuals in Colombia and Ecuador.

Geographic Range [top]

Range Description:This species occurs on the Pacific slopes of the Andes in Ecuador (in Pichincha Province, where it is known from three localities), north to the northern extent of the western slope of the Cordillera Occidental in Colombia. Its recorded altitudinal range is 1,780-1,820m in Colombia, but has been found down to 1,350m in Ecuador. The Ecuadorian population appears to be isolated from that in Colombia.

Population [top]

Population:In Ecuador, the species seems to have undergone a severe decline, and it has not been recorded in recent years. It remains uncommon in Colombia.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a species of undisturbed cloud forest, and has not been found in secondary habitats. It breeds in streams, with the eggs laid on leaves overhanging the water.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The most likely cause of the severe decline of this species is the movement of the cloud layer up the mountain sides as a result of climate change, resulting in reduced humidity within the altitudinal range of the species (probably exacerbated by habitat fragmentation). Additional likely threats include deforestation, due to agricultural development (including the planting of illegal crops), fire, logging, and human settlement; the introduction of alien predatory fish species in streams; and pollution resulting from the spraying of illegal crops. Chytridiomycosis also cannot be ruled out.

Conservation Actions [top]

Conservation Actions: It occurs in three Natural National Parks in Colombia: Farallones de Cali, Munchique, and Tatama. It is not known from any protected areas in Ecuador. There is a need for further survey work in Ecuador to establish the current population status of the species in the wild.
