|Scientific Name:||Oedipina gracilis|
|Species Authority:||Taylor, 1952|
|Red List Category & Criteria:||Endangered A2ac ver 3.1|
|Assessor(s):||Bolaños, F., Savage, J., Wake, D., Ibáñez, R. & Solís, F.|
|Reviewer(s):||Stuart, S.N., Chanson, J.S., Cox, N.A. & Young, B.E.|
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.
|Range Description:||This species is known from the Atlantic lowlands of Costa Rica and extreme north-western Panama, at 3-710m asl.|
Native:Costa Rica; Panama
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It was formerly common, but is now very rare, though still surviving at several sites, including La Selva Biological Station in Costa Rica.|
|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.|
|Major Threat(s):||Habitat destruction due to expanding agriculture, logging and human settlements is probably the main cause of the decline.|
|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.|
