their pools with the larger Bufo marinus toads. Diseases The pathogenic fungus Batrachochytrium dendrobatidis has had no impact on this toad. Conservation When the species had been less studied, earlier authors such as Bolaños & Chaves writing for the IUCN in 2004 mistakenly believed it to be endemic to Costa Rica. As such it was automatically added to the local Red List and considered threatened. It was described in 2004 as most likely not very tolerant of deforestation and siltation and pollution of its breeding habitat, but nonetheless it was downgraded to "least concern" in 2004. As of 2008 the IUCN describes it as "widespread and regularly encountered" and "common and somewhat adaptable with a presumed large population". It is regularly seen during the breeding period, and is common in wet forests at higher elevations at favoured habitats. It occurs at La Selva Biological Station, in the Monteverde Cloud Forest Reserve (if correctly identified) and throughout the Maquenque National Wildlife Refuge in Costa Rica, and in the Indio Maíz Biological Reserve and Río San Juan Wildlife Refuge in Nicaragua. It is kept in an ex situ collection at the Costa Rican Amphibian Research Center.
