Invasive aliens

"Today's countryside is filled with squirrels and sycamores, ladybirds and pheasants, even Canada and Egyptian geese aren't out of place. The British Isles have been colonised by a succession of animals, plants, fungi and other organisms that apparently belong elsewhere. Indeed, it's often hard to sort out the native from the foreign. Some species, like the Asian hornet, cause problems; others, like snowdrops and daffodils, are cherished. Non-native organisms, invasive or otherwise, from rabbits to rhododendrons, mink to muntjac, hold up a mirror to our own species. The pace of invasion is now higher than ever, but non-natives, problematic or peaceful, aren't a modern phenomenon. From the earliest settlement of our islands and our 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."--The publisher
