This frog species lives on a single fragment of montane rainforest within Parque Nacional Cusuco, Departamento de Cortés in northern Honduras. This threatened cloud forest habitat covers approximately 200km<sup>2</sup> and ranges in altitude from 500-2200m; within that range, <i>P. dasypus</i> is present only in the core zone of the park from 1410-1990m. <i>Plectrohyla dasypus</i> is a stream-associated species and can be found on low vegetation along stream and river margins when they emerge to forage at night. Occasionally, they can also be found in bromeliads. <p>There has been an 80% population decline of <i>P. dasypus</i> over the past ten years that can be closely linked to the presence of amphibian chytrid fungus, <i>Batrachochytrium chytridiomycosis</i>. Annual surveys from 2007 to present have shown that the majority of the population is infected. Chytrid frequently causes oral deformities in <i>P. dasypus</i> tadpoles, producing eroded jaw sheaths and gaps in tooth rows. Chytrid appears to cause the greatest mortality in recently metamorphosed frogs (very young adults) and this is likely to have a strong negative effect on recruitment of adults. This species is also threatened by degradation in the quality and extent of habitat due to a recent severe increase in illegal deforestation within the national park where it lives. <p>Because this frog is found nowhere else in the world and chytrid fungus is found throughout its habitat, establishing captive populations will be very important for its survival. The ‘Honduran Amphibian Rescue and Conservation Center’ is a new effort supported by a 2012 Amphibian Ark Seed Grant that will combat the decline of <i>P. dasypus</i> and two additional Critically Endangered amphibian species facing similar threats. In this program, tadpoles and froglets will be collected from the wild, treated for any chytrid fungal infections and raised in a controlled environment in a disease-free facility, and reintroduced back into the wild as healthy adult frogs.
