Identification Guide to the Non-Native Invasive Plants of Britain and Ireland

This accessible guide gives you the tools to be confident in identifying and managing frequently encountered non-native invasive plants in Britain and Ireland.

Invasive alien species (IAS) are one of the biggest drivers of global biodiversity loss along with climate change and habitat fragmentation. If allowed to colonise unchecked, they can have irreversible negative impacts on the integrity of the natural environment and associated ecosystem services. In spite of widescale efforts, there has been an almost exponential increase in new introductions to Britain and Ireland in the last 20 years. The only way we can tackle them is to engage both professionals and the public in mapping their distribution, and to encourage everyone to take the right actions to contain them. This book will help you:

• Identify frequently encountered non-native invasive plants and know their potential impacts.


• Differentiate lookalikes, including how to separate native species from closely related non-native invasive species.


• Understand the extent of invasive potential, including trees, grasses, freshwater aquatics and seaweeds.


• Quickly check the legislation so you know which species should be reported and to whom.


• Prevent mistakes - often, with best intentions, people take action which makes the situation worse.


• Avoid introducing invasive species into your gardens and local environment.

Packed with illustrations, maps and tips, this book is a practical tool and reference for professional ecologists, environmentalists, gardeners and everyone interested in the protection and sustainable management of our countryside and green spaces.
