Which savanna zones are characteristic locations for the Euxerus genus?

Sahel and Sudanian savanna zones

The genus *Euxerus* occupies a distinct territory spanning the western and central parts of the African continent, clearly demarcated from the ranges of the eastern *Xerus* and southern *Geosciurus*. The characteristic zones where these squirrels are found are specifically identified as the Sahel and Sudanian savanna zones. This geographic area is defined by a seasonal climate that includes distinct wet and dry periods. A key ecological requirement noted for these squirrels is the presence of sufficient tree cover within these savanna regions, which provides essential shade protection during the hottest parts of the day, a slight contrast to the more open savanna preference sometimes exhibited by East African species.
