Western Australias State Weed Plan

"This book describes and illustrates plant species that are weeds in Western Australia. Most of them have been introduced to the State, but a few are native plants that have expanded their ranges as a result of human activity or have become weeds of cultivation." -- Preface.

"This is a reference book containing information on over 200 species, including where each is proclaimed and what the legal requirements are for its control. Each weed has a detailed description and colour photograph to make identification straightforward." - product description.

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.

This text provides instruction on the concepts and application of risk analysis in the field of regulatory plant protection, covering topics such as the background on why and how risk analysis is conducted and specific methods for implementing risk analysis. This book also provides useful exercises and case studies to aid students of plant pathology and crop protection in their absorption of the subject. Equally useful for practitioners, this book is written by experts with a wealth of national and international experience. Students of plant pathology and crop protection as well as practitione.

The Pilbara region in Australia’s arid northwest is rich in flora that is suited to extreme temperatures and boom and bust cycles of moisture availability. It is also a region important for its natural resources. In places where mining activities have finished and the land is under management for ecological restoration, there is increasing demand for information about native plant communities and the biology of their seeds. Pilbara Seed Atlas and Field Guide is the first book to combine plant identification with robust, scientific criteria for cost-effective seed-based rehabilitation. It describes 103 regional plant taxa and provides guidelines for effective collection, cleaning, storage and germination of their seeds. It addresses issues such as timing of collection, quality and viability of seed, and dormancy release, which are essential for successful restoration programs. With photographs to portray the subtle differences and unique features of each species’ biology, this book will be of great use to practitioners in the field, including environmental consultants, rehabilitation companies, commercial seed collectors and government authorities, as well as naturalists and people interested in growing the Pilbara’s remarkable plants.
