Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Book Description
This comprehensive guide to wetland weeds covers both native and introduced species, ranging from minor or localised environmental problems to those that should not be tolerated in any situation. The author takes a pragmatic approach to weed control, recognising that some weeds may not be possible to eradicate, and emphasising the need to assess the extent and future potential of any infestation before taking action. Weed control should be planned in the context of the overall management goals for any type of wetland, the types of habitat weeds provide or overrun, and whether they can be replaced successfully with more appropriate plants. A range of strategies for controlling wetland weeds are considered, from containment actions to prevent the development of a soil seed bank to physical removal, and biological approaches from biocontrol to shading, overplanting and use of turbidity. The widespread use of chemical controls is also discussed, with the warning that these are often only a short-term cure and can cause more harm to aquatic ecosystems than the weeds they are holding at bay. More than 130 species of established weeds are included with information on their origins, nutrient responses, environmental effects, habitat values, prospects for containment or eradication, and even culinary uses. Other sections look at native plants as weeds, including a number of species of uncertain origins, and potential weeds still being legally sold through the aquarium and nursery trades.

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
