Here, at last, is a lavishly illustrated manual for ready identification of 299 common and economically important weeds in the region south to Virginia, north to Maine and southern Canada, and west to Wisconsin. Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower.*A dichotomous key to all the species described in the book is designed to narrow the choices to a few possible species. Identification can then be confirmed by reading the descriptions of the species and comparing a specimen with the drawings and photographs.*A fold-out grass identification table provides diagnostic information for weedy grasses in an easy-to-use tabular key.*Specimens with unusual vegetative characteristics, such as thorns, square stems, whorled leaves, or milky sap, can be rapidly identified using the shortcut identification table. The first comprehensive weed identification manual available for the Northeast, this book will facilitate appropriate weed management strategy in any horticultural or agronomic cropping system and will also serve home gardeners and landscape managers, as well as pest management specialists and allergists.

You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.
An Illustrated Guide to Their Identification and Control
Author: Elizabeth J. Czarapata
Publisher: Univ of Wisconsin Press
Invasive Plants of the Upper Midwest is an informative, colorful, comprehensive guide to invasive species that are currently endangering native habitats in the region. It will be an essential resource for land managers, nature lovers, property owners, farmers, landscapers, educators, botanists, foresters, and gardeners. Invasive plants are a growing threat to ecosystems everywhere. Often originating in distant climes, they spread to woodlands, wetlands, prairies, roadsides, and backyards that lack the biological controls which kept these plant populations in check in their homelands. Invasive Plants of the Upper Midwest includes more than 250 color photos that will help anyone identify problem trees, shrubs, vines, grasses, sedges, and herbaceous plants (including aquatic invaders). The text offers further details of plant identification; manual, mechanical, biological, and chemical control techniques; information and advice about herbicides; and suggestions for related ecological restoration and community education efforts. Also included are literature references, a glossary, a matrix of existing and potential invasive species in the Upper Midwest, an index with both scientific and common plant names, advice on state agencies to contact with invasive plant questions, and other helpful resources. The information in this book has been carefully reviewed by staffs of the Wisconsin Department of Natural Resources Bureau of Endangered Resources and the University of Wisconsin-Madison Arboretum and other invasive plant experts.
It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role

What if, one step at a time, we could make our gardens and landscapes more eco-friendly? Barbara W. Ellis's colorful, comprehensive guide shows homeowners, gardeners, garden designers, and landscapers how to do just that for the large and beautiful Chesapeake Bay watershed region. This area includes Maryland, Virginia, Delaware, Washington, D.C., and part of West Virginia (translating to portions of USDA Zones 6, 7, and 8). Here, mid-Atlantic gardeners, from beginners to advanced, will find the essential tools for taking steps to make their gardens part of the solution through long-term planning and planting. The guide is built from the ground up around six simple but powerful principles that anyone can use: * Reduce lawn * Build plant diversity * Grow native plants * Manage water runoff * Welcome wildlife * Garden wisely Included are detailed instructions for assessing and designing your particular garden or landscape site; choosing and caring for trees, shrubs, vines, ground covers, and flowers; and succeeding with such conditions as shade or poor soil. From rain gardens to woodland gardens, meadow gardens to wildlife gardens, and much more, this indispensable guide features more than 300 color photographs.
Because of its central location and geographical diversity, Kentucky is home today to perhaps the richest diversity of non-native plants east of the Rocky Mountains, and weeds make up a large component of the state's flora and vegetation. Many of Kentucky's weeds are immigrants that came to the New World from the Old and were brought to Kentucky by travelers, explorers, and settlers. This guide to the identification of 160 weeds commonly found in crops, pastures, turf, and along roadsides provides ecological, geographical, and ethnobotanical information with each species description. It is the most extensive reference on weeds in this botanically unique area. A must for all agriculturalists, naturalists and botanists.

In 1640, French explorer LaSalle was astonished to find a royal Native American kingdom northeast of New Orleans. Moving along the social and political wire, many of that Nachay tribe owned plantations with both white and black slaves by the early 1700s. One hundred and fifty years later, Major Elias Paix and his wife, Princess Melissa, along with the chief of the tribe, sold their plantations to purchase a paddle steamer and supplies in order to establish a new town as the capital of an all-Indian state. Paix fought for the South alongside Robert E. Lee, and after the war he traveled with Chief Mather to establish the town of Yellow Creek. A few years later Prince Dell, son of the Major and Melissa, sets off on the expedition at age fourteen. He exhibits unwavering duty to his tribe and has to cope with the fallout from a hasty decision made in disobedience, the loss of a beloved family member, and white men encroaching upon this new settlement. In fulfilling his unique punishment, Dell embarks upon a political career that may just facilitate much-needed unity among the Nachay tribe and other Indians.
