Madagascar is ranked 12th in amphibian species richness by the International Union on the Conservation of Nature (IUCN) and is considered to be one of the highest priority countries for amphibian conservation. Nearly one quarter of the island’s amphibian species are threatened with extinction with habitat alteration and over-harvesting for the pet trade contributing most to this dra- matic decline. The impending threat of the amphibian chytrid fungus Batrachochytrium dendrobati- dis (5c/), which has been associated with many of the world’s recent amphibian population declines and extinctions, is of great concern. In response to the tremendous threats facing Madagascar’s amphibians, a national strategy for amphibian conservation was developed, emphasizing the need for ex situ conservation action. This project was officially launched through a collaborative effort between a community-run organization, the IUCN, and the Malagasy government. With significant financial support from multiple international agencies, the result was the construction of a captive We breeding facility in Andasibe, east-central Madagascar. discuss the process for developing and implementing this project which has included facility construction, terrarium building, culturing lo- cal feeder insects, and the training of Malagasy technicians. This is the first captive breeding and amphibian conservation project of its kind in Madagascar. Our hope is that it will not only serve as a model for other range country facilities, but become a center for training and education in an area of Madagascar that contains tremendous amphibian diversity and endemism.
