Scientific Name:	Oedipina gracilis
Species Authority:	Taylor, 1952

Assessment Information [top]

Red List Category & Criteria:	Endangered A2ac ver 3.1
Year Published:	2004
Assessor/s:	Federico Bolaños, Jay Savage, David Wake, Roberto Ibáñez, Frank Solís
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Contributor/s:
Justification: Listed as Endangered because of an observed serious population decline, estimated to be more than 50% over the last three generations, based a greatly reduced number of observations of the species, and on shrinkage and degradation of its habitat. The generation length is assumed to be 7 years.

Geographic Range [top]

Range Description:	This species is known from the Atlantic lowlands of Costa Rica and extreme north-western Panama, at 3-710m asl.
Countries:	Native: Costa Rica; Panama

Population [top]

Population:	It was formerly common, but is now very rare, though still surviving at several sites, including La Selva Biological Station in Costa Rica.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits lowland rainforest, where it can be found in leaf-litter, under rotten logs, moss or rocks, on tree trunks or on the ground. It can tolerate very limited habitat degradation. Breeding takes place by direct development.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Habitat destruction due to expanding agriculture, logging and human settlements is probably the main cause of the decline.

Major Threat(s):

Conservation Actions [top]

Conservation Actions:	It occurs in the La Selva Biological Station and Reserve in Costa Rica, but there are otherwise very few protected areas within its range. The species is in need of close population monitoring.
