Wild beaver have already set up home on the former farm - Derek is breeding several species of native wild animals to populate his 'stone age' park.
Back to the future - A farmer is returning his land back to the Stone Age and reintroducing species of wild animals once extinct in the UK - after becoming disenchanted with 'unsustainable' modern farming techniques.
Derek Gow is using a herd of Nazi-engineered cows to spearhead his radical rewilding scheme that will create the farming version of Jurassic Park.
The Heck cows that died out in the Iron Age were re-established in Nazi Germany in the 1930s as part of a genetics programme to create a breed of super cattle.
Joining them on Mr Gow's 115 acre ring-fenced plot of upland in Devon will be rabbit-eating wildcats, wild boar and beavers.
