One of two dragon species native to the British Isles, the Common Welsh Green could be found mostly in the mountainous regions of Wales. Largely avoidant of humans, the Common Welsh Green was a mostly gentle creature and preyed mainly on sheep. This was also the dragon breed that Fleur Delacour faced in the Triwizard Tournament, but the Common Welsh Green's melodious roar and narrow jets of fire were no match for the young witch's Slumbering Spell.
