The impact of invasive organisms is second only to habitat loss as a threat to biodiversity and yet, despite increasing ecological awareness, people remain largely unaware of these plants and animals and their potentially devastating impact. Although most biological introductions fail, many prove successful and these can prove disastrous for native fauna and flora.This field guide will enable the identification of a range of invasive plants and animals now found in Britain. Though these species are of particular concern to conservationists there has previously been no unified guide devoted to their recognition. This book will act both as an ID guide, appealing to the amateur naturalist, and as an important tool for ecologists and land managers attempting to tackle the problem posed by invasive species.

A beautifully illustrated guide to all the ladybirds of Britain and Ireland.
"A ground-breaking identification guide ... the perfect marriage of artistic excellence, deep knowledge and, dare I say it, of scientists' genuine affection." BRETT WESTWOOD
This brand new illustrated field guide covers all 47 species of ladybird occurring in the British Isles in a handy and easy-to-use format. Twenty-seven species are colorful and conspicuous and easily recognized as ladybirds; the remaining species are more challenging, but the clear illustrations and up-to-date text in this guide will help to break down the identification barriers. A useful introduction provides an overview of ladybird ecology, tips on studying and recording, and suggested sites for finding ladybirds. The main part of the book comprises detailed species texts, covering field characters, food, habitats, suggested survey methods, ranges, conservation statuses and distribution trends. An illustrated at-a-glance identification guide and helpful pointers for differentiating similar-looking species are also included. With 102 color photographs and 47 distribution maps, combined with Richard Lewington's peerless artwork, this is the definitive guide to one of our most cherished and charismatic insect groups.
