100 Alien Invaders
Animals and Plants That are Changing Our World

Animals and plants are perfectly harmless in their native areas, but become a menace when they colonise new territories - often out-competing native species and, in some instances, drastically affecting the ecology. What's more, it is humankind that is largely responsible. This title exposes 100 of the most destructive alien species on the planet.

Animals and plants are perfectly harmless in their native areas, but become a menace when they colonise new territories - often out-competing native species and, in some instances, drastically affecting the ecology.

Read this book and you'll never look at house sparrows or hedgehogs in the same way again. "100 Alien Invaders" is a warts-and-all expose of 100 of the most destructive alien species on the planet.
