Invasive alien species are a major and growing threat to biodiversity worldwide. The transport of organisms through increased levels of trade and tourism is leading to the widespread breaching of natural biogeographic barriers at unprecedented rates. Consequences can be severe, especially in naturally isolated ecosystems. Invasive alien species can cause the extinction of vulnerable endemic species, alter the structure and composition of communities, disrupt successional pathways, and lead to the loss of ecosystem services. Global climate change may further exacerbate the spread of alien species, as climatic zones shift and potential ranges alter.
The effective management of invasive alien species is clearly a
priority for biological conservation worldwide. This book first
provides strategies for managing such species at successive
invasion stages, from prevention at the border to control of major
infestations. It then describes the general tools and approaches
that are recommended for successful management of particular groups
of invasive organisms in a range of environments. In each case, the
ecological basis and practical requirements of invasive alien
species management are addressed.
This integration of proven techniques and policies will be useful
to a wide readership of students, academics, conservation
practitioners, invasive species managers, legislators, and to the
broader community concerned with biological conservation.
