Book Description
The impact of invasive species on native vegetation is a major threat to biodiversity all over the world - a threat ranked second only to habitat destruction. Other negative effects of weed invasions include reduced ecosystem services, loss to agricultural production and impacts on human health. This work covers the discipline of risk assessment as applied to the invasion ecology of plants. Taking a global context, it synthesizes theories on plant invasions, introduces a variety of models for weed risk assessment, and addresses procedures for ranking invasive species on a range of scales to determine weeds of national significance. It shows how the application of risk assessment to weed invasion may help reduce weed impact and thereby improve living conditions for people throughout the world. This text is aimed at invasions ecologists, botanists, quarantine officers, policy-makers and community groups wanting to know more about this developing discipline.

Book Description
Great uncertainty typically surrounds decisions and management actions in the conservation of biodiversity and natural resource management, and yet there are risks of serious and irreversible harm for both biodiversity and the humans that rely on it. The precautionary principle arguably underlies all international conservation efforts and promotes acting to avoid serious or irreversible environmental harm, despite lack of scientific certainty as to the likelihood, magnitude or cause of harm. This book is the first to examine the application of the precautionary principle to biodiversity conservation and natural resource management, incorporating perspectives from scientists, economists, lawyers and practitioners from both developing and developed countries. It analyses the application and impacts of the principle in many areas including forestry, invasive alien species, wildlife trade, protected areas and fisheries, in a range of national and international contexts. Particular attention is drawn to issues of equity, livelihoods, science and politics, and the book provides guidelines for applying the precautionary principle to biodiversity conservation and natural resource management.

Book Description
A decade ago, Tim Low journeyed to the remote northernmost tip of Australia. Instead of the pristine rain forests he expected, he found jungles infested with Latin American carpet grass and feral cattle. That incident helped inspire Feral Future, a passionate account of the history and implications of invasive species in that island nation, with consequences for ecological communities around the globe. Australia is far from alone in facing horrific ecological and economic damage from invading plants and animals, and in Low's capable hands, Australia's experiences serve as a wake-up call for all of us. He covers how invasive species like cane toads and pond apple got to Australia (often through misguided but intentional introductions) and what we can do to stop them. He also covers the many pests that Australia has exported to the world, including the paperbark tree (Melaleuca) that infests hundreds of thousands of acres in south Florida.

Book Description
This thesis gives an overview of factors used in weed risk assessments and explores the disparity between the measured high accuracy rate of the weed risk assessment system (WRA) as implemented in Australia and the pessimistic assessments of some workers about the possibility of predicting the weed potential of plant species imported in the future. The accuracy of the WRA may not be as high as previously thought, and it varies with weed definition and taxonomic groups. Cluster analysis and comparative analysis by independent contrasts were employed to determine the value of individual biological and ecological questions on the WRA questionnaire. Results showed that some WRA questions could be deleted from the questionnaire and the scores for others weighted differently. The WRA is not a reliable predictor of weeds when it is considered in the context of the base-rate probability of an introduced plant becoming weedy in Australia. As a result a far greater number on non-weeds will be placed on the prohibited imported list than was initially expected.

Book Description
Biological control of weeds has been practiced for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts - the technique, when practiced as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practicing biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australiawill provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students. KEY FEATURES * A unique collation of information for Australian weed research and management * Contains all the information about biological control of weeds in Australia in one book * Provides key references for further information * Will become a well cited publication

Book Description
Invasive alien species are among today's most daunting environmental threats, costing billions of dollars in economic damages and wreaking havoc on ecosystems around the world. In 1997, a consortium of scientific organizations including SCOPE, IUCN, and CABI developed the Global Invasive Species Programme (GISP) with the explicit objective of providing new tools for understanding and coping with invasive alien species. Invasive Alien Species is the final report of GISP's first phase of operation, 1997-2000, in which authorities from more than thirty countries worked to examine invasions as a worldwide environmental hazard. The book brings together the world's leading scientists and researchers involved with invasive alien species to offer a comprehensive summary and synthesis of the current state of knowledge on the subject. Invasive alien species represent a critical threat to natural ecosystems and native biodiversity, as well as to human economic vitality and health. The knowledge gained to date in understanding and combating invasive alien species can form a useful basis on which to build strategies for controlling or minimizing the effects in the future. Invasive Alien Species is an essential reference for the international community of investigators concerned with biological invasions.
