Management and Ecology of Freshwater Plants


Book Description

There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.




Wetland Weeds


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.




Invasive Plants of California's Wildlands


Book Description

"Invasive nonnative plants threaten native species with habitat loss, displacement, and severe population declines, thus seriously reducing biodiversity. Invasive Plants of California's Wildlands is a tremendous source for land managers and others who are interested in protecting the rich natural heritage of California and surrounding states."--John C. Sawhill, President and CEO, The Nature Conservancy







Biology and Control of Aquatic Plants


Book Description

Biology and Control of Aquatic Plants: A Best Management Practices Handbook is the fourth edition of a handbook produced by the not for profit Aquatic Ecosystem Restoration Foundation (AERF). The mission of the AERF is to support research and development which provides strategies and techniques for the environmentally and scientifically sound management, conservation and restoration of aquatic ecosystems. One way the Foundation accomplishes this mission is by producing this handbook to provide information to the public regarding the benefits of aquatic ecosystem conservation and aquatic plant management. The first, second and third editions of this handbook became some of the most widely consulted references in the aquatic plant management community. This fourth edition has been specifically designed with water resource managers, water management associations, homeowners and customers and operators of aquatic plant management companies and districts in mind. Our goal in preparing this handbook is to provide basic, scientifically sound information to assist decision-makers with their water management questions.




Weed Management Handbook


Book Description

Weed Management Handbook updates the 8th edition of Weed Control Handbook (1990). The change in the title and contents of the book from previous editions reflects both the current emphasis on producing crops in a sustainable and environmentally-friendly manner, and the new weed management challenges presenting themselves. This landmark publication contains cutting edge chapters, each written by acknowledged experts in their fields and carefully drawn together and edited by Professor Robert Naylor, known and respected world-wide for his knowledge of the area. The sequence of chapters included reflects a progression from the biology of weeds, through the underpinning science and technology relating to weed management techniques including herbicides and their application to crops, leading to principles of weed management techniques. Finally a set of relevant case studies describes the main management options available and addresses the challenges of reduced chemical options in many crops. Weed Management Handbook is a vital tool for all those involved in the crop protection / agrochemical industry, including business managers, horticultural and agricultural scientists, plant physiologists, botanists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying horticultural and agricultural sciences, plant physiology, botany and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Weed Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Publishing.




Water Hyacinth


Book Description

The water hyacinth is a disruptive factor in aquatic ecosystem management and ecosystem services, and causes problems in fisheries, transportation waterways, irrigation, hydropower generation, and water resources. To address these concerns, it is necessary to integrate past studies with current research and innovations to identify where the knowledge gap is and to creatively assess and solve the problems in a global context. This book provides comprehensive coverage of new research and technological innovations for the application of controlling, managing, harvesting, postharvest processing and utilizing the water hyacinth.

Australia's Poisonous Plants, Fungi and Cyanobacteria


Book Description

Australia's Poisonous Plants, Fungi and Cyanobacteria is the first full-colour, comprehensive guide to the major natural threats to health in Australia affecting domestic and native animals and humans. The overriding aim of the book is to prevent poisoning, as there are few effective treatments available, particularly in domestic animals. The species have been chosen because of their capacity to threaten life or damage important organs, their relative abundance or wide distribution in native and naturalised Australian flora, or because of their extensive cultivation as crops, pastures or in gardens. These include flowering plants, ferns and cone-bearing plants, macrofungi, ergot fungi and cyanobacteria. The plant species are grouped by life form such as herbs, grasses and sedges, shrubs, trees, and for flowering plants by flower type and colour for ease of identification. Species described have colour photographs, distribution maps and notes on confusing species, habitats, toxins, animals affected, conditions of poisoning, clinical signs and symptoms, post mortem changes, therapy, prevention and control. Symbols are used for quick reference to poisoning duration and available ways of managing poisoning. As further aids to understanding, poisoning hot-spots are highlighted and the book lists plants under the headings of animals affected and organs affected. A Digest gives brief details for all poisonous species in Australia. This book is written in a straightforward style making it accessible to a wide audience including farmers, veterinarians, agricultural advisors, gardeners, horticulturists, botanists and park rangers, medical practitioners and paramedics, teachers, parents and pet owners. First published in 2012 as a hardback and made available in eBook format in 2020.
