Wechselkröte
The fauna lacks endemism and most species found are widespread. There are abundant small mammals including many gerbil species, the endangered four-toed jerboa "Allactaga tetradactyla" and the Günther's vole "Microtus guentheri". Barbary sheep "Ammotragus lervia" and mountain gazelle "Gazella cuvieri" still have populations in the region, as does the striped hyena "Htaena hyaena", and these are mixed with mammals which have more European origins such as wild boar "Sus scrofa", Eurasian otter "Lutra lutra" and red fox "Vulpes vulpes". These European affinities are echoed in the herpetofauna where grass snake "Natrix natrix", Sahara frog "Pelophylax saharicus" and the European green toad "Bufo viridis" mixed with the African common toad "Amietophrynus regularis". The North African ostrich "Struthio camelus camelus" occurred in this region but is now largely extirpated.
