This Order, which applies in England, varies Part 1 of Schedule 9 to the Wildlife and Countryside Act 1981 (c. 69), which lists non-native animals which are established in the wild which may not be released or allowed to escape into the wild unless authorised by a licence. Article 2 adds common pheasant and red legged partridge to Part 1 of Schedule 9 to the Act, but only in relation to areas of England that are European sites or are within 500 metres of the boundary of these sites.
