Alteration of the Great Plains landscape during the past two centuries has permitted scores of weedy plants to flourish and expand their ranges, often profoundly affecting the ecology and economy of the region. As their numbers have increased, weed identification has become progressively more challenging. More than 600 of the 3,600 species of flowering plants and ferns documented in the Great Plains were not here 200 years ago. This book, updating and replacing Weeds of Nebraska and the Great Plains (1994), intends to enable users to "identify or confirm the identity of the most important weeds in the Great Plains."
