Balkan and Greek Tortoises, two "exotic" tortoises in France

These two species are not native to France and should normally not be found in the wild in Corsica and the French mainland. But sometimes, because of releases of captive individuals, these exotic species are found in nature. 

Crosses with wild populations of Hermann’s Tortoise are possible, they contribute to the degradation of natural populations by generating hybrid individuals less adapted to the local conditions than native specimens.
