premise: There are seven species of deer living wild in Britain. The Red Deer and the Roe Deer are native species. Fallow Deer were introduced by the Romans and, since the seventeenth century, have been joined by three other non-native species: Sika, Muntjac and Chinese Water Deer the ancestors of which have escaped from parks. In addition, a herd of Reindeer was established in Scotland in 1952. Most of the Red Deer in Britain are found in Scotland, but there are significant wild populations in south-west and north-west England, East Anglia and the north Midlands. Red deer can interbreed with the introduced Japanese Sika deer and in some areas, hybrids are common.
hypothesis: There are no Reindeer in England.
