North American Bullfrog - Lithobates cafesbeianus

This species is a menace and needs to be reported to the local Amphibian and reptile group.

African Clawed Toad - Xenopus laevis

Used in research, escaped and deliberate releases led to several colonies notably in the Isle of Wight and South Wales, where the only occasional sightings are reported.

Alpine Newt - Triturus alpestris

European Pond Terrapin - Emys orbicularis

Released pets have formed this population, it is not certain if they are breeding but numbers are stable possibly due to continued introductions and longevity of individuals. They can be found in the south of England mainly in slow flowing rivers.

The Norfolk broads apparently holds a small population but this cannot be confirmed.

Red Eared Terrapin - Trachemys scripta elegans

Released pets have formed this population, it is not certain if they are breeding but recent finds of eggs combined with the recent warmer climate make this a matter only of time. Current numbers are stable possibly due to continued introductions and longevity of individuals.

They can be found in the south of England particularly in parks and gardens.

European Tree Frog - Hyla arborea

Small populations existed in Dorset and the Isle of Wight, two larger populations persisted until recently in London and the New Forest. A small population still survives in Essex.
