Amphibians are by far the most threatened taxonomic group in Atewa Forest. Of the 40 species that have been recorded, 30% are threatened or near-threatened with extinction. There are many species that are cryptic and poorly known, and likely to be many species that remain undiscovered.

Afia-Birago Puddle Frog Phrynobatrachus afiabirago recently described from specimens collected in Atewa Forest (Adam Leache).

In 2018 a new species of frog – Afia Birago Puddle Frog Phrynobatrachus afiabirago – was described from specimens collected in Atewa Forest and Jukwa Forest (Ofori-Boateng et al 2018). Since Jukwa Forest is now just a small fragment of just 0.5 hectare it is likely this species will be entirely dependent on Atewa Forest for its survival. Once assessed it is likely that this species will be classified as Critically Endangered.

 

This [Togo] Slippery Frog Conraua derooi photographed in Atewa Forest, is now known to be a distinct species from the population in western Togo making it entirely restricted to Atewa (J. Lindsell).

The Togo Slippery Frog Conraua derooi is a Critically Endangered species known only from Atewa and some forest patches in the western Togo highlands. Recent analysis has shown that the population in Atewa Forest is distinct at the species level and scientists (C. Ofori-Boateng & M.O. Rodel pers. comm.) are currently writing the account to describe this as a new species. This species will certainly be entirely dependent on Atewa Forest for its survival. The population of Conrauau in Atewa Forest is found only in fast flowing rocky streams with clear water, under closed canopy forest, and at relatively high altitudes. These conditions only exist on streams that flow off the plateau of the highest parts of the Atewa range, in the northern sector of the forest. This is probably the single most vulnerable species to any mining activity that may occur on the bauxite plateau since it will be impossible to control the impact on the streams on which they are dependent. There is therefore an extremely high risk that even limited mining could lead to the global extinction of this species.
