Book Description
Weeds are variously defined as plants growing where they are not wanted, plants that interfere with human activity. Weeds affect everyone in the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding, reducing animal health, preventing water flow, as plant parasites, etc. It is estimated that those problems cause $ billions worth of crop losses annually and the global cost of controlling weeds also runs into many $ billions every year. Atlas of Weed Mapping presents an introductory overview on the occurrence of the most common weeds of the world. The book notably includes: Description of cropping practices and explanations for the global distribution of weeds Invasive plant mapping Aquatics and wetland plants with histological plant details Theoretical and practical aspects of weed mapping Aspects on the documentation of herbicide resistance Biodiversity, rare weeds and the dominance of the most common weeds Fully illustrated with more than 800 coloured figures and a number of tables, this new characterisation of anthropogenic vegetation will be interesting for readers of a great number of disciplines such as agriculture, botany, ecology, geobotany and plant community research. More than a hundred experts have contributed data to this unique compilation.

Book Description
Early recognition and control of weeds invariably leads to considerable savings in the cost of herbicides used on crops and in gardens. This atlas is an indispensable full colour photographic guide to the 40 most common weeds afflicting arable farmland and gardens. The weeds have all been photographed at cotyledon and seedling stage to permit early identification and control. Accompanying line drawings highlight major features and calendar germination and flowering times.

Book Description
Identify and control weeds with this colorful, expanded edition—with bonus CD For more than a decade, the Color Atlas of Turfgrass Weeds has been the leading authority for green industry professionals in their ongoing quest to control weeds and limit deleterious effects: the weed clumps, color variation, and unsightly patches that disrupt turf uniformity. The Second Edition of this essential resource has been expanded and updated to provide control information that professionals need to maintain the quality that is so vital to the golf, sports field, and managed landscape industries. This new and expanded edition includes these vital updates: 50 new weed profiles, plus 400 additional, high-quality, full-color photographs featuring photographs of the weed in habit, the seedhead or flower, and in some cases, what the weed looks like when dormant An accompanying CD that features more than 1,000 photographs Valuable control strategies and recommendations for every weed Each weed alphabetically arranged by family and scientific name An alphabetical index that shows all the weeds featured

Book Description
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.

Book Description
This volume comprises updated nomenclature, distribution, and habitat data for the species in the area covered in the four parts of Flora Palaestina, by Michael Zohary and Naomi Feinbrun-Dothan (Jerusalem: The Israel Academy of Sciences and Humanities, 1966-1986). The distribution data are presented here in individual maps for each of the species recorded in the study area (defined as lying west of 360E). Four main phytogeographical regions - the Mediterranean, Irano-Turanian, Saharo-Arabian, and Sudanian - meet in Israel. The area's broad climatic and edaphic diversity is largely responsible for its botanical wealth - some 9.06 species per 100 sq. km. Of the 2,750 species listed herein, 276 were not previously recorded in Flora Palaestina. The 18,000 species-per-district records that form the basis of Flora Palaestina have been expanded to some 28,400, based largely on the author's investigations over the course of some forty years. Most of Israel's flora is documented in the Herbarium of the Hebrew University of Jerusalem, which aims to preserve all the species in the Flora Palaestina area.
