The Common Welsh Green dragon, or just Welsh Green, is a native of Wales. It nests in the higher mountain regions where a reservation has been set up for it.

History:
Fleur Delacour faced this breed of dragon for the First Task of the Triwizard Tournament in 1994. She enchanted the creature into a magical slumber to retrieve her golden egg.

Traits:
This dragon is a relatively subdued breed (except for the rare exception of the Ilfracombe Incident). It prefers to prey mainly on sheep and other small mammals and to avoid human contact altogether. The Welsh Green's roar is rather distinctive and somewhat melodious and it issues its fire in narrow jets. The eggs of the Common Welsh Green are earthy brown, flecked with green.

It is possible that a young Common Welsh Green may have been the actual cause of the Great Fire of London.
