| C2 | Naturalised established species – species with established populations resulting from introduction by man, but which also occur in an apparently wild state, e.g. Grey-lag Goose. |
| C3 | Naturalised re-established species – species with populations successfully re-established by man in areas of former occurrence, e.g. Red Kite. |
| C4 | Naturalised feral species – domesticated species with populations established in the wild, e.g. Rock Dove/Feral Pigeon. |
| E | Species that have been recorded as introductions, human-assisted transportees or escapees from captivity, and whose breeding populations (if any) are thought not to be self sustaining. Species in category E that have bred in the wild in Britain are designated as E*. Category E species form no part of the British List (unless already included under categories A, B or C). |
