Our countryside is filled with grey squirrels and parakeets, snowdrops and pheasants, rhododendrons and rabbits, none of which are indigenous to Britain. The pace of invasion is now higher than ever before. But, non-natives, problematic or peaceful, aren’t a modern phenomenon: they’ve always been with us. From the earliest settlement of our islands and the first experiments with farming, through the Roman and medieval times, to the age of exploration by Europeans and the current period of globalised free-for-all, the story of invasive species is the story of our own past, present and future. In INVASIVE ALIENS the naturalist, writer, environmental consultant and wildlife film-maker Dan Eatherley tells the remarkable story of Britain's Invasive Aliens. Copies of INVASIVE ALIENS - a Sunday Times, Daily Telegraph and Waterstones Book of the Year - will be available to purchase and get signed by Dan at the event.
