Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA BUFONIDAE

Scientific Name: Amietophrynus superciliaris
Species Authority: (Boulenger, 1888)
Common Name(s):
English African Giant Toad, Congo Toad
Synonym(s):
Bufo superciliaris Boulenger, 1888
Taxonomic Notes: This form is probably a complex of three species (M.-O. Rödel pers. comm.). The population in the Upper Guinea forest block is suspected to be a different species from that in Central Africa. Amietophrynus chevalieri may not be a synonym of Amietophrynus superciliaris, but could be the species that occurs in the Upper Guinea forest (A. Hillers pers. comm. 2009).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2004-04-30
Assessor(s): Mills Tandy, Jean-Louis Amiet, Mark-Oliver Rödel, Annika Hillers
Reviewer(s): Stuart, S. & Chanson, J. and Cox, N. (Global Amphibian Assessment Coordinating Team)
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species' main range is from extreme southeastern Nigeria eastward towards northeastern Democratic Republic of Congo. There are records from southwestern and southern Cameroon, mainland Equatorial Guinea, northern Congo, southwestern Central African Republic and central Gabon. In West Africa, there are isolated records from southern Ghana, southwestern Côte d’Ivoire, Liberia and southern Guinea. It does not appear to have been recorded from Sierra Leone, but it is likely to occur in this country. It is generally a low-altitude species.

Population [top]

Population: It is generally uncommon through most of its range. It is very rare in West Africa.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: In Central Africa, it lives mainly in secondary forest, but also in tall primary forest, as well dense brush and cocoa plantations. In West Africa, it is restricted to primary forest along the banks of larger rivers. It breeds in relatively calm water in streams.
Systems: Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: The international trade of this species is probably now greatly reduced.

Threats [top]

Major Threat(s): Although it is tolerant of some habitat modification in central Africa, it is probably affected to some extent by forest loss, especially when the habitat becomes very open. In the past it has been harvested for the pet trade, and this might have impacted some populations, and so low-level illegal trade might continue. The West African form is considered to be possibly threatened (Hillers and Rödel 2007), given that in Upper Guinea it is found exclusively in large, healthy forests, never in smaller or degraded forests, and large pristine forests are very rare and threatened in Upper Guinea due to logging, small-holder agriculture and more and more mining activities [e.g. iron ore in Guinea] (A. Hillers pers. comm. 2009).

Conservation Actions [top]

Conservation Actions: It is included in Appendix I of CITES. It occurs in the Oban Hills National Park in Nigeria, the Korup National Park in Cameroon, the Taï National Park in Côte d’Ivoire, the Massif du Ziama Biosphere Reserve in Guinea, the Monte Alen National Park in Equatorial Guinea, in North Lorma National Forest in Liberia, and almost certainly in several other protected areas. The Upper Guinea population requires further taxonomic studies (A. Hillers pers. comm. 2009).
