Holdridge's toad, formerly Bufo holdridgei, is a species of toad endemic to Costa Rica. In October 2008, it was declared extinct by the International Union for Conservation of Nature in its Red List since the species had not been seen since 1987, despite years of extensive searches. However, the species was rediscovered in 2010 by a Costa Rican herpetologist and is now classified as critically endangered. It is believed that the species is most threatened by the presence of the chytrid fungus in its habitat.
The Korean water toad, Korean toad, water toad, or Stejneger's toad, is a species of toad found in East Asia.

It is endemic to Chile and occurs in the western and eastern slopes of the Chilean Coast Range in Valdivia and Osorno Provinces.

It is a rare species threatened by habitat loss that is caused by siltation of streams caused by clear cutting and afforestation with exotic species.
Telmatobufo bullocki is a species of frog in the family Calyptocephalellidae. It is endemic to Chile, and is only known from a few locations in the Cordillera de Nahuelbuta, a part of the Chilean Coast Range. It is extremely rare; extensive fieldwork in 1992–2002 turned up only a single adult. It occurs in fast-flowing streams in temperate Nothofagus forest. The tadpoles are free-swimming and feed on algae growing on submerged rocks. It is threatened by siltation of streams caused by clear-cutting. It occurs within the Nahuelbuta National Park.
Telmatobufo venustus is a species of frog in the family Calyptocephalellidae. It is endemic to Chile and occurs on the western slopes of the Andes in Maule and Bío Bío Regions. Its natural habitats are streams in temperate Nothofagus forests where it is found under rocks along the streams. The only stable population is in the Altos de Lircay National Reserve in Maule. The only other localities, both in the Bío Bío Region, are its type locality in Chillan, where it was not found in 2014, and Ralco where it was last observed in 1981. It is threatened by habitat loss caused by fires, conversion of native habitat to pine and eucalyptus plantations, and in Ralco, hydropower dams. Trout in Altos de Lircay are also a threat.
