The Alien Plant Working Group of the Plant Conservation Alliance, located in Washington, D.C., offers fact sheets about the impact and threat of alien shrubs to the natural ecosystems of the United States. The fact sheets include a description of the native range, habitat, and ecological threat of the alien shrubs, as well as a discussion of their distribution and management approaches in the United States.
This site provides a compiled national list of invasive plants infesting natural areas throughout the USA, background information on the problem of invasive species, illustrated fact sheets that include plant descriptions, native range, distribution and habitat in the USA, management options, suggested alternative native plants, and other information, and selected links to relevant people and organizations.
Provides information for the general public, land managers, researchers, and others on the serious threat and impacts of invasive alien (exotic, non-native) plants to the native flora, fauna, and natural ecosystems of the United States. This site provides a compiled national list of invasive plants infesting natural areas throughout the U.S., background information on the problem of invasive species, illustrated fact sheets that include plant descriptions, native range, distribution and habitat in the U.S., management options, suggested alternative native plants, and other information, and selected links to relevant people and organizations.
Invasive alien species are a major threat to biodiversity and ecosystems throughout the world. In India, a country with four of the world's most important 'biodiversity hotspots', the invasion of alien plants means risking a national ecological disaster with major social and economic consequences. Currently, there is insufficient information about invasive alien plants; their distribution, rate of spread and adaptability to new environments. This book reveals existing and potential invaders, evaluates the level of risk they pose to native species and suggests steps to manage spread and limit damage. Invaluable to policy-makers, this book is also required reading for researchers of invasive plants worldwide.
Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.
The Alien Plant Working Group of the Plant Conservation Alliance, located in Washington, D.C., offers fact sheets about the impact and threat of aquatic alien plants to the natural ecosystems of the United States. The fact sheets include a description of the native range, habitat, and ecological threat of aquatic alien plants, as well as a discussion of their distribution and management approaches in the United States.
The Alien Plant Working Group of the Plant Conservation Alliance, located in Washington, D.C., offers fact sheets about the impact and threat of herbs that are alien plants to the natural ecosystems of the United States. The fact sheets include a description of the native range, habitat, and ecological threat of alien herbs, as well as a discussion of their distribution and management approaches in the United States.
Identify and understand the plants that are changing the North American landscape forever.
An easy-to-use, wide-ranging guide to invasive plants in North America. Features full-color photos and descriptions of more than 250 alien species—both terrestrial and aquatic—that are in some cases changing the landscape to an almost unimaginable degree. Accompanying text describes the plant's environmental and economic impacts as well as management techniques used to control it. Also includes an explanation of what an invasive is and a step-by-step identification key. An essential guide to understanding this unprecedented environmental challenge.
