The Mississippi Map Turtle (Graptemys kohni) bred in Canada is currently (2013) the most common turtle in the pet trade, so we can expect to see more of these in our wetlands basking along with the Red-eared Slider. Sliders are common in our area, originating from released pets. It is uncertain whether sliders can breed successfully in nature in BC climates, but this is possible at least occasionally in years with favourable environmental conditions.
Rare Turtles from the pet trade
Asian Box Turtle (Cuora amboinensis)
Central American Wood Turtle (Rhinoclemys pulcherima)
Tortoises would not survive here and are expensive (250-500$) to purchase, so it is unlikely that they will be released into the wild.There are no records of tortoises from the wild in BC.
