EN Rhamphophryne macrorhina Trueb, 1971<br />
Endangered B1ab(iii)+2ab(iii)<br />
Order, Family: Anura, Bufonidae<br />
Country Distribution: Colombia<br />
Current Population Trend: Decreasing<br />

Geographic Range This species is known from the type locality: Santa Rita, in Antioquia Department, Colombia,<br />
between 1,890 and 1910m asl. It is also known from two other locations in Colombia: Guatape (Mesopotamia) and<br />
Amalfi (Anori) all in Antioquia Department, in the central Andes, between 1,800 and 1,900m asl. There is no suitable<br />
habitat available to the species between these known localities.<br />
Population It is a common species.<br />
Habitat and Ecology It occurs in the leaf-litter of sub-Andean and Andean forests, and is restricted to primary and<br />
good secondary forest. It most likely breeds by direct development like other species in the genus.<br />
Major Threats Habitat fragmentation and loss, due to the expansion of agriculture, timber extraction, desiccation,<br />
and the fumigation of illegal crops, are all major threats to the species’ habitat. Climate change may also be a threat,<br />
given that this species occurs at relatively high elevations.<br />
Conservation Measures The range of the species includes the Reserva La Forzosa, but other tracts of montane<br />
forest remain in urgent need of formal protection.<br />

Order, Family: Anura, Bufonidae<br />

Geographic Range This species is known from the type locality, “El Chaquiro, [department of] Antioquia, Colombia”<br />
(amended to “Hacienda Palmas, El Chaquiro, Antioquia Department, Colombia, 2,670m elevation”), and from nearby<br />
locations.<br />
Population It is a common species within its relatively small range.<br />
Habitat and Ecology It occurs in high-altitude grassland, and has not been recorded from anthropogenic habitats.<br />
It breeds by direct development.<br />
Major Threats The main threat is habitat loss due to expanding pastures for cattle grazing. Climate change may<br />
be a threat in the future.<br />
Conservation Measures The range of this species does not include any protected areas, such that habitat protection<br />
remains the most urgent conservation action required. Further survey work is needed to determine whether it<br />
occurs outside the vicinity of the type locality.<br />

CR Rhamphophryne rostrata (Noble, 1920)<br />
Critically Endangered B1ab(iii)+2ab(iii)<br />
Order, Family: Anura, Bufonidae<br />
Country Distribution: Colombia<br />
Current Population Trend: Decreasing<br />
Geographic Range This species is known only from the type<br />
locality: “Santa Rita Creek, fourteen miles north of the village of<br />
Mesopotamia in the southern part of the Department of Antioquia,<br />
Colombia”, at 2,472m asl. It is unlikely to range more widely.<br />
Population This species is known from only two specimens collected<br />
in 1914. Searches of the type locality since then have not found it,<br />
and it is possible that it is now extinct.<br />
Habitat and Ecology The type locality was forest when the<br />
specimens were collected, but the exact habitat requirements of the<br />
species are still unknown. It presumably breeds by direct development<br />
like other species in the genus.<br />
Major Threats At the type locality there has been significant logging<br />
in the past, and there is now high human population density in this<br />
area with accompanying increased infrastructure development for<br />
human settlement. Agriculture, including the planting of illegal crops,<br />
is also a threat in the area as well as fumigation of illegal crops.<br />
Conservation Measures The type locality is not within a protected area. Further survey work is needed to establish<br />
whether or not the species still occurs at the type locality or in any location outside the type locality, as the species<br />
might already be extinct in view of the scale of habitat destruction in the general vicinity.<br />

Order, Family: Anura, Bufonidae<br />
Country Distribution: Ethiopia<br />

Geographic Range This species is endemic to the mountains of south-central Ethiopia (Arsi, Balé, Sidamo and<br />
Gamo Gofa Provinces) at 1,950-3,520m asl. With the exception of the population in the Gughe Mountains, all records<br />
are from east of the Rift Valley.<br />
Population It is locally common within its limited range.<br />
Habitat and Ecology It is essentially a species of montane forest, though perhaps extending marginally into<br />
open moorland. It has been observed breeding in a small, probably temporary, pool in a grassy glade surrounded by<br />
Hypericum woodland.<br />
Major Threats It is threatened by environmental degradation resulting from human settlement, specifically the<br />
destruction of forests through both subsistence and commercial exploitation.<br />
Conservation Measures The species is relatively common in the Bale Mountains National Park, but there is a need<br />
for improved protection of other sites at which this species has been recorded.<br />
