A unique history of plant and animal invaders of the British isles spanning thousands of years of arrivals and escapes, as well as defences mounted and a look to the future. As Brits we pride ourselves as stoic defenders, boasting a record of resistance dating back to 1066.
Yet, even a cursory examination of the natural world reveals that while interlopers of the human variety may have been kept at bay, our islands have been invaded, conquered and settled by an endless succession of animals, plants, fungi and other alien lifeforms that apparently belong elsewhere. Indeed it's often hard to work out what actually is native, and what is foreign.
From early settlement of our islands, through the Roman and medieval period, to the age of exploration and globalisation, today's complement of alien species tells a story about our past.
"[...] To sum up, Eatherley’s thorough digest of a complex subject is engaging, informative and balanced. It is the first of these which most explains why Invasive Aliens has garnered such a sheaf of book awards. If the journalistic style puts off a few readers, it will please many more because the subject has been presented with verve and panache; I did not expect to be drawn in so comprehensively or to learn so much. [...] We should encourage as many people as possible to understand this important issue. Reading this book is a very good place to start."
– James Robertson,British Wildlife, Volume 32(1), October 2020
"Fascinating [...] Eatherley has the unflagging curiosity of a Victorian explorer. The man seems to be indefatigable as he hacks away at Himalayan balsam (the pink, flowery weed that lines almost every riverbank in Britain) or goes on patrol for invasive signal crayfish in the River Barle. He's not afraid to get wet, dirty or tired on his mission to get up close and personal with intruders of all shapes and sizes. It feels as if we are on the front line with him."
– The Times
"[Eatherley's] approach to his complex subject is open-minded, nuanced, and free-ranging to the point of wildness"
– Sunday Telegraph
"Fascinating [...] the story of "invasive species" is really the story of human history, and [Eatherley] tells it with great verve"
– Daily Telegraph
"Eatherley has an impressive grasp of history – both human and natural [...] [and] Invasive Aliens provides a well-researched overview of this complex and controversial topic. There is plenty here to surprise as well as enlighten"
– Literary Review
"This book is a fascinating, comprehensive and thoughtful compendium of the flora and fauna that have reached our shores over the years. The apocalyptic vision of how so much of our native wildlife is being annihilated – from bluebells to red squirrels to crayfish – is tempered with hope: natives develop immunities and some invaders may even be an improvement. Invasive Aliens is full of extraordinary and often complex stories [...]"
– Robin Hanbury-Tenison, Countryfile, September 2019
