Ghana has a rich stock of biological diversity as it
lies within the three main bio-geographical zones, namely: the south
western portion within the Guineo-Congolian, the middle belt
within the Guineo-Congolian/Sudanian transition zone, while the northern-tip
of the country falls within the Sudanian zone.
Despite the lack of information on the full coverage of
the biological resources of the country in such areas as the marine and
other aquatic ecosystem, so far about 2,974 indigenous plant species,
504 fishes, 728 birds, 225 mammals, 221 species of amphibians and
reptiles have been recorded. Three species of frogs, 1 lizard, and 23
species of butterflies have been reported to be
endemic.
