Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA HEMIPHRACTIDAE

Scientific Name: Gastrotheca dendronastes
Species Authority: Duellman, 1983
Taxonomic Notes: This genus has recently been moved from the family Hylidae (Faivovich et al. 2005).

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in the Colombian and Ecuadorian Andes.

Geographic Range [top]

Range Description: This species occurs on the Pacific slopes of the Andes in southern Colombia (in the departments of Antioquia, Risaralda, Choco, Valle del Cauca and Cauca), and in one locality in the southern part of Pichincha Province, in northern Ecuador. There is also an isolated population at Florencia in the department of Caldas on the eastern slopes of the Central Cordillera in Colombia. Its altitudinal range is 1,230-2,090m asl. It probably occurs more widely than is currently known.

Population [top]

Population: It is rare in Ecuador, where it has not been found in recent years, but it is still common in Colombia.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It lives on vegetation inside primary and secondary montane forests, usually near water sources. It breeds by direct development; the eggs are carried on the back of the female.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threats are habitat loss due to agricultural development (livestock, illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops. Fire is probably also a threat in some places. Its apparent disappearance in Ecuador could be due to habitat loss, but chytridiomycosis, which has affected other species of Gastrotheca in Ecuador, cannot be ruled out.

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas in Colombia, including Parque Nacional Natural Farallones de Cali, but none in Ecuador. There is a need for close population monitoring of this species given the potential threat of chytridiomycosis.
