This species is known from the Maya Mountains in Belize south to the Caribbean foothills of Guatemala, including the Sierra de Santa Cruz, the Montañas del Mico, and the eastern portion of the Sierra de las Minas, from sea level up to 1,160m asl.
Habitat and Ecology
It lives on the forest floor near streams in moist forest, and is not found in degraded habitats. Breeding is by direct development, and the species is not dependent on water for breeding.
It has declined drastically in Guatemala, where it is now extinct at localities where previously hundreds could be found in a few hours. It is now rare at those Guatemalan localities where it still survives. It is still common in Belize.
The major threat is habitat loss due to agriculture, wood extraction, and human settlement. It is declining, even where suitable habitat remains, for reasons that are not understood. However, some other species of Eleutherodactylus that are associated with streams have undergone dramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should be monitored carefully.
It occurs in the Columbia River Forest Reserve and probably in the Bladen Forest Reserve in Belize; and in the Montanas del Mico Catchment Reserve and the Reserva de la Biosfera Sierra de las Minas in Guatemala. Further research is needed to determine the reasons for the decline of this species in suitable habitat.
Red List Status
Listed as Endangered because of a drastic population decline estimated to be more than 50% over the last three generations, perhaps due to chytridiomycosis.
