Two tree frogs inhabit remote areas of Bolivia, which harbor an astounding diversity of vertebrate species. Yet much of the country remains scientifically poorly documented for frogs—including the protected areas. In 2001, Raoul Bain from AMNH's Center for Biodiversity and Conservation teamed up with Bolivian scientists to survey the frogs of one biological hotspot—the Amboró-Madidi corridor of the High Andes. Documenting Bolivia's frog species is a first step toward bolstering conservation efforts.
