Taxonomic Notes: This species might be a complex of species, hence its apparently varying conservation status in the different countries in its range (J.V. Rueda pers. comm., Guayasamin et al., in press).

Assessment Information [top]

Red List Category & Criteria: Vulnerable A2a ver 3.1
Year Published: 2010
Date Assessed: 2008-11-07
Assessor(s): Juan Manuel Guayasamin
Reviewer(s): Ariadne Angulo and Simon Stuart
Listed as Vulnerable because of a population decline, projected to be more than 30% over the next 10 years, in much of its Ecuadorian range.

Population [top]

Population:In Ecuador, at Yanayacu Biological Station, only three individuals of Centrolene buckleyi were found after an intensive 3-year inventory effort, suggesting that that this species is quite rare at this locality (Guayasamin et al., 2006). Elsewhere in Ecuador (e.g. Pilaló) the species was formerly abundant; however, it is now absent from these localities (Bustamante et al., 2005; J.M. Guayasamin, pers. comm. 2008). It is still easily found in Colombia, while in Peru it is known only from two recent specimens.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species lives in montane primary and secondary forests, in páramo bushland and grassland, and in terrestrial bromeliads in inter-Andean valleys. It is nocturnal, sometimes arboreal, and lays its eggs on leaves above streams, the larvae then develop in these streams. In Ecuador, C. buckleyi seems to reproduce in the months of April and May in permanent streams. One clutch was found to contain 18 eggs (J.M. Guayasamin, pers. comm. 2008).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): It appears not to be affected by habitat loss, surviving in areas with heavy human impact. The serious decline in Ecuador is thought to be due to chytrid fungus. However, predictions suggest that, in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).

Conservation Actions [top]

Conservation Actions: There are several protected areas where it occurs, although other conservation actions may be contemplated in the event of positive detection of chytrid fungus in this species.
