This species occurs in Africa south of the Sahara from Mauritania eastward to Sudan, South Sudan, Eritrea and Djibouti; and in the Sahara, in the Trarza region (Mauritania) and in the Air mountains (Niger). Records from Yemen refer to Bufo tihamicus. It is not present in Egypt, reports by Anderson (1898) refer to modern day Sudan (S. Baha El Din pers. comm.). There do not appear to be records from Côte d’Ivoire, Togo, Chad and Central African Republic, but it is likely to occur in these countries.
Habitat and Ecology
It is a species of xeric environments such as dry savannas and semi-deserts. It breeds in temporary puddles and ponds, and has been found close to rivers in Cameroon, although in Benin it appears to avoid rivers and creeks as breeding sites (Nago et al. 2006).
It is a common species.
Drought is likely to be the most significant threat to this species, although in parts of its range an increase in the populations of humans and their domestic livestock is likely to impact unfavourably on the overall environment, perhaps especially breeding habitats.
It occurs in several protected areas.
Bufo chudeaui Chabanaud, 1919, which is known only from inadequate post-metamorphic material (rendering it a nomen dubium) from Mali could belong to this species (Tandy and Feener 1985).
