This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.

Each entry details the target weed, control agent, year of first release, country of origin of agent, status and degree of control, research organisation involved, and key references. The catalogue format has been modified slightly from earlier editions to improve ease of use. The book provides an invaluable means of keeping track of the world situation, and is a handy reference for professionals, research workers and students interested in the biological control of weeds.

In addition to the theory and principles of weed management, this book provides information about twenty-nine of the most serious weeds in the West, including weed identification, origin, history and distribution, invasion potentials, biology and ecology, and specific management options. Full-color photographs and distribution maps help illustrate the plants and the invasive threat they pose. An invaluable resource for land managers, resource specialists, and students of natural resource management, Biology and Management of Noxious Rangeland Weeds provides practical, science-based information needed for sustainable weed management and land restoration.

Though the forests are still green and the lakes full of water, an unending stream of invasions is changing many ecosystems around the world from productive, tightly integrated webs of native species to loose assemblages of stressed native species and aggressive invaders. The earth is becoming what author David Quammen has called a "planet of weeds." Nature Out of Place brings this devastating but overlooked crisis to the forefront of public consciousness by offering a fascinating exploration of its causes and consequences, along with a thoughtful and practical consideration of what can be done about it. The father and son team of Jason and Roy Van Driesche offer a unique combination of narratives that highlight specific locations and problems along with comprehensive explanations of the underlying scientific and policy issues. Chapters examine Hawaii, where introduced feral pigs are destroying the islands' native forests; zebra mussel invasion in the rivers of Ohio; the decades-long effort to eradicate an invasive weed on the Great Plains; and a story about the restoration of both ecological and human history in an urban natural area. In-depth background chapters explain topics ranging from how ecosystems become diverse, to the characteristics of effective invaders, to procedures and policies that can help prevent future invasions. The book ends with a number of specific suggestions for ways that individuals can help reduce the impacts of invasive species, and offers resources for further information. By bringing the problem of invasive species to life for readers at all levels, Nature Out of Place will play an essential role in the vital effort to raise public awareness of this ongoing ecological crisis.

Describes a ranking system used to evaluate the potential invasiveness and impacts of 113 non-native plants to natural areas in Alaska. Species are ranked by a series of questions in four broad categories: ecosystem impacts, biological attributes, distribution, and control measures. Also included is a climate screening procedure to evaluate the potential for establishment in three ecogeographic regions of Alaska [Juneau, Fairbanks, Nome].
