|Population:||Formerly a common species, no specimen has been seen since 1989. It last bred in normal numbers in 1987, and its breeding sites were well known. In 1988, only eight males and two females could be located. In 1989, a single male was found, and was the last record of the species. Extensive searches since this time have failed to produce any more records (as of August, 2007).|
|Habitat and Ecology:||It lived in cloud and elfin forest, and was recorded breeding in temporary pools at the beginning of the rainy season.|
|Major Threat(s):||Its restricted range, global warming, chytridiomycosis and airborne pollution probably contributed to this species' extinction.|
Its entire range was protected by the Reserva Biológica Monteverde.
It is listed on CITES Appendix I (as Bufo periglenes).
