In the United Kingdom we have 12 naturally occuring or native species, 6 amphibians and 6 reptiles. Evidence is mounting that a 13th species, the Pool Frog, was once a native of Norfolk.

There are a number of introduced species, naturalised in the wider countryside. Some introduced species may pose a threat to native wildlife, these are listed separately.
