We live in a globalized world in which people and goods are transported across ecosystem boundaries in greater volumes and faster than ever before. One consequence of globalization has been the introduction, establishment, and spread of many thousands of species beyond the ecosystems in which they evolved. Many of these species cause harm, and are referred to as invasive. This sub-set of non-native species is now recognized to be one of the largest global drivers of environmental change, and policy is being developed at local, national and international scales to address the issues. Enacting policies that will successfully reduce the impacts of invasive species requires contributions from economists, ecologists, legal scholars, historians, engineers, and many more. Many experts from these disciplines are working on invasive species, but this work has rarely crossed disciplinary boundaries. This book brings together experts from many disciplines to present multi-disciplinary perspectives on the impacts of invasive species, and how policy can be created and enacted to reduce those impacts.
