Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA ELEUTHERODACTYLIDAE

Scientific Name: Eleutherodactylus thorectes
Species Authority: Hedges, 1988

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A3c; B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-12-18
Assessor(s): Blair Hedges, Richard Thomas, Robert Powell
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Critically Endangered because of an expected population decline of greater than 80% over the next ten years, predicted from severe degradation of the species' habitat on the Massif de la Hotte; Haiti; and because it has an Extent of Occurrence of less than 100km2 and an Area of Occupancy of less than 10km2, all individuals are in a single sub-population, and the extent of its forest habitat is declining.
History:
2004 Critically Endangered

Geographic Range [top]

Range Description:One of the smallest frogs in the world, this species has a very restricted range, occurring only on the peaks of Formon and Macaya at high elevations on the Massif de la Hotte, Haiti. Its altitudinal range is from 1,700-2,340 m asl.

Population [top]

Population: Believed to be common in suitable habitat, it was last recorded in 1991 (although there have been no surveys of the area since).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It is slightly arboreal in closed montane pine and cloud forest with shrubs, tree ferns, bromeliads, and climbing bamboo. Eggs are laid on the ground and it breeds by direct development.
Systems: Terrestrial

Threats [top]

Major Threat(s): Severe habitat destruction is taking place primarily due to logging (charcoal collection) by local people and slash-and-burn agriculture.

Conservation Actions [top]

Conservation Actions: This species is known only from the Parc National Macaya, but there is no management of this area for conservation, and the habitat continues to be destroyed. Urgent site-based action is required in the Massif de la Hotte to conserve the remaining habitat in the area. Survey work is also necessary to determine the current population status of this species.
