Despite the fact that fighting weeds was of paramount importance to the agricultural development of Canada, there has scarcely been any research on understanding the origins and history of these lowly plants. The War on Weeds in the Prairie West is the first full-blown environmental history of weeds in western Canada.

This guide describes a total of 230 species in the text and illustrates partially or completely 154 species. The guide begins with a general introduction to weeds, losses because of their presence in crops, and their characteristics, control, and identification. Detailed descriptions are then given by family and include common members of that family. Information is given on names, description, origin, distribution in Canada, habitat, and similar plants.

The plant species that humans rely upon have an extended family of wild counterparts that are an important source of genetic diversity used to breed productive crops. These wild and weedy cousins are valuable as a resource for adapting our food, forage, industrial and other crops to climate change. Many wild plant species are also directly used, especially for revegetation, and as medicinal and ornamental plants. North America is rich in these wild plant genetic resources. This book is a valuable reference that describes the important crop wild relatives and wild utilized species found in Canada, the United States and Mexico. The book highlights efforts taken by these countries to conserve and use wild resources and provides essential information on best practices for collecting and conserving them. Numerous maps using up-to-date information and methods illustrate the distribution of important species, and supplement detailed description on the potential value these resources have to agriculture, as well as their conservation statuses and needs. There is broad recognition of the urgent need to conserve plant diversity; however, a small fraction of wild species is distinguished by their potential to support agricultural production. Many of these species are common, even weedy, and are easily overshadowed by rare or endangered plants. Nevertheless, because of their genetic proximity to agriculturally important crops or direct use, they deserve to be recognized, celebrated, conserved, and made available to support food and agricultural security. This comprehensive two-volume reference will be valuable for students and scientists interested in economic botany, and for practitioners at all levels tasked with conserving plant biodiversity. The chapters 'Public Education and Outreach Opportunities for Crop Wild Relatives in North America' and 'Genetic Resources of Crop Wild Relatives – A Canadian Perspective' are open access under a CC BY 4.0 license via link.springer.com.

Manage Weeds on Your Farm: A Guide to Ecological Strategies provides you with in-depth information about dozens of agricultural weeds found throughout the country and the best ways of managing them. In Part One, the book begins with a general discussion of weeds: their biology, behavior and the characteristics that influence how to best control their populations. It then describes the strengths and limitations of the most common cultural management practices, physical practices and cultivation tools. Part Two is a reference section that describes the identification, ecology and management of 63 of the most common and difficult-to-control weed species found in the United States.
