. Numbers of frogs are dwindling, and in the Cusuco National Park, where the habitat is fully protected, at least part of the cause of the decline is believed to be the disease chytridiomycosis caused by the fungus '' Batrachochytrium dendrobatidis''. Elsewhere this frog is also threatened by loss of habitat caused by forest clearance for agricultural purposes and by water pollution.
