Introduced species include the Italian wall lizard, the pond slider and the common snapping turtle.
[13] The olive ridley sea turtle (Lepidochelys olivacea) was observed for the first time in Metropolitan France in 2017, on the Atlantic coast near the Isle of Oléron.
[14] The pond slider (Trachemys scripta) was introduced in France through the pet trade, having been imported in large numbers starting in the 1980s.
It has since been reported in nearly all French departments, and acts as a competitor to the native European pond turtle, with which it shares an ecological niche.
[16] After import of pond sliders was banned in 1997, the common snapping turtle (Chelydra serpentina) was commercialized in France, with former pets being released in the wild.
