Six species of amphibians are native to Great Britain :
The two species introduced into the Pnod are shown below:
Frogs are usually seen in spring or early summer when they return to the water to breed. Although the common frog is the only native species in the British Isles, two other species have been introduced in southern England - the edible frog and the marsh frog.
The smooth (or common) newt enters the water to breed in the spring and can often be seen as it rises to the surface for air. In the breeding season the males develop a small crest and take on a prominent pattern of spots. Females are dorsally a dull brown colour. Both sexes have an orange ventral colour.
