|Scientific Name:||Rhinella rostrata|
|Species Authority:||(Noble, 1920)|
Rhamphophryne rostrata (Noble, 1920)
|Red List Category & Criteria:||Critically Endangered B1ab(iii)+2ab(iii) ver 3.1|
|Assessor/s:||Wilmar Bolívar, John Lynch|
|Reviewer/s:||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat.
|Range Description:||This species is known only from the type locality: "Santa Rita Creek, fourteen miles north of the village of Mesopotamia in the southern part of the Department of Antioquia, Colombia", at 2,472m asl. It is unlikely to range more widely.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||This species is known from only two specimens collected in 1914. Searches of the type locality since then have not found it, and it is possible that it is now extinct.|
|Habitat and Ecology:||The type locality was forest when the specimens were collected, but the exact habitat requirements of the species are still unknown. It presumably breeds by direct development like other species in the genus.|
|Major Threat(s):||At the type locality there has been significant logging in the past, and there is now high human population density in this area with accompanying increased infrastructure development for human settlement. Agriculture, including the planting of illegal crops, is also a threat in the area as well as fumigation of illegal crops.|
|Conservation Actions:||The type locality is not within a protected area. Further survey work is needed to establish whether or not the species still occurs at the type locality or in any location outside the type locality, as the species might already be extinct in view of the scale of habitat destruction in the general vicinity.|
