Nonindigenous plants and plant pests that find their way to the United States and become invasive can often cause problems. They cost more than $100 billion per year in crop and timber losses plus the expense of herbicides and pesticides. And this figure does not include the costs of invasions in less intensively managed ecosystems such as wetlands. Nonindigenous Plants and Plant Pests examines this growing problem and offers recommendations for enhancing the science base in this field, improving our detection of potential invaders, and refining our ability to predict their impact. The book analyzes the factors that shape an invader's progress through four stages: arriving through one of many possible ports of entry, reaching a threshold of survival, thriving through proliferation and geographic spread, and ultimate impact on the organism's new environment. The book also reviews approaches to predicting whether a species will become an invader as well as the more complex challenge of predicting and measuring its impact on the environment, a process involving value judgments and risk assessment. This detailed analysis will be of interest to policymakers, plant scientists, agricultural producers, environmentalists, and public agencies concerned with invasive plant and plant pest species.

Fire has shaped the Australian landscape and the lives of Australians for thousands of years—and will continue to do so as the climate changes. For all our advances in prevention and prediction, planning and communication, bushfires keep claiming our lives and our homes. How can we avoid another Ash Wednesday or Black Saturday?Danielle Clode has lived in the bushfire danger zone and studied the past and recent history of fire management and fire-fighting. Here she tells the complex story of Australia’s relationship with fire, from indigenous practices to country fire brigades and royal commissions—as well as her own story of living with the threat of fire. A Future in Flames is a vivid history, a sombre reflection and an invaluable guide for living and dealing with fire.
