Dispersal and exposure to amphibian chytrid fungus ( Batrachochytrium dendrobatidis ,  Bd ) is not confined to the aquatic habitat, but little is known about pathways that facilitate exposure to wild terrestrial amphibians that do not typically enter bodies of water. We explored the possible spread of  Bd  from an aquatic reservoir to terrestrial substrates by the emergence of recently metamorphosed infected amphibians and potential deposition of  Bd -positive residue on riparian vegetation in Cusuco National Park, Honduras (CNP). Amphibians and their respective leaf perches were both sampled for  Bd  presence and the pathogen was detected on 76.1% (35/46) of leaves where a  Bd -positive frog had rested. Although the viability of  Bd  detected on these leaves cannot be discerned from our quantitative PCR results, the cool air temperature, closed canopy, and high humidity of this cloud forest environment in CNP is expected to encourage pathogen persistence. High prevalence of infection (88.5%) detected in the recently metamorphosed amphibians and frequent shedding of  Bd -positive residue on foliage demonstrates a pathway of  Bd  dispersal between aquatic and terrestrial habitats. This pathway provides the opportunity for environmental transmission of  Bd  among and between amphibian species without direct physical contact or exposure to an aquatic habitat.
