Available in PDF, EPUB and Kindle. Book excerpt: Invasive weed species are a threat to the health and functionality of many rangeland systems. Downy brome (Bromus tectorum) is an invasive annual grass that affects the productivity of rangelands by decreasing the grazing capacity for livestock as well as altering the wildfire cycle and competing against more desirable vegetation for limited resources. In 2006, an Invasive Plant Management Plan and Environmental Assessment was approved for Dinosaur National Monument, calling for prioritization of invasive species management on high value wildlife habitat, vector areas, and for species with a high ecological impact. The Cub Creek Watershed was identified as a priority for immediate attention due to its high historical, recreational, and environmental significance. This research was another phase of an integrated effort to manage vegetation in the Cub Creek Watershed and surrounding rangelands. Field work at two locations within Dinosaur National Monument was coupled with greenhouse experiments to evaluate chemical and mechanical methods of downy brome seed reduction and control, and to evaluate the response of four weedy grasses to herbicides used in broadleaf weed management practices.

This book was released on 2016-01-22 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasions by exotic grasses, particularly annuals, rank among the most extensive and intensive ways that humans are contributing to the transformation of the earth’s surface. The problem is particularly notable with a suite of exotic grasses in the Bromus genus in the arid and semiarid regions that dominate the western United States, which extend from the dry basins near the Sierra and Cascade Ranges across the Intermountain Region and Rockies to about 105° longitude. This genus includes approximately 150 species that have a wide range of invasive and non-invasive tendencies in their home ranges and in North America. Bromus species that became invasive upon introduction to North America in the late 1800’s, such as Bromus tectorum and B. rubens, have since became the dominant cover on millions of hectares. Here, millenia of ecosystem development led to landscapes that would otherwise be dominated by perennial shrubs, herbs, and biotic soil crusts that were able to persist in spite of variable and scarce precipitation. This native ecosystem resilience is increasingly coveted by land owners and managers as more hectares lose their resistance to Bromus grasses and similar exotics and as climate, land use, and disturbance-regime changes are also superimposed. Managers are increasingly challenged to glean basic services from these ecosystems as they become invaded. Exotic annual grasses reduce wildlife and livestock carrying capacity and increase the frequency and extent of wildfi res and associated soil erosion. This book uses a unique ecoregional and multidisciplinary approach to evaluate the invasiveness, impacts, and management of the large Bromus genus. Students, researchers, and practitioners interested in Bromus specifically and invasive exotics in general will benefit from the depth of knowledge summarized in the book.
Download or read book Downy Brome Control Strategies for Southwestern Saskatchewan written by and published by . This book was released on 1993 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Downy brome (Bromus tectorum L.) has spread throughout southwestern Saskatchewan over the last 15 years to become a serious weed in various crops, pasture, and rangeland. This report presents results of field trials conducted over three years to evaluate herbicides, rotations, and intensive grazing as management tools for controlling downy brome. The investigators evaluated 26 herbicides for downy brome control and crop tolerance in winter wheat, fall rye, fallow, alfalfa, and grass hayland. They tested the compounds in isolation, as tank mixes, and with various adjuvants. Minor use proposals were submitted for five of the herbicides evaluated. The tests included evaluation of growth, seed production, and soil seedbank of downy brome in various crop rotations, and assessment of the effect of intensive spring grazing with cattle in reducing downy brome seed production.

Download or read book Weed Control written by Nicholas E. Korres and published by CRC Press. This book was released on 2018-12-19 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: In light of public concerns about sustainable food production, the necessity for human and environmental protection, along with the evolution of herbicide resistant weeds, call for a review of current weed control strategies. Sustainable weed control requires an integrated approach based on knowledge of each crop and the weeds that threaten it. This book will be an invaluable source of information for scholars, growers, consultants, researchers and other stakeholders dealing with either arable, row, cash, vegetables, orchards or even grassland-based production systems. The uniqueness of this book comes from the balanced coverage of herbicide effects on humans and environment in relation to best weed control practices of the most important cropping systems worldwide. Furthermore, it amalgamates and discusses the most appropriate, judicious and suitable weed control strategies for a wide range of crops. It reviews the available information and suggests solutions that are not merely feasible but also optimal.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Download or read book A Novel Method for Removing Downy Brome from Reclamation Seed written by William Rose and published by . This book was released on 2015 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disturbance increases infestation potential for weeds such as downy brome (Bromus tectorum ). Downy brome often contaminates seed used in reclamation efforts. Because downy brome germinates more rapidly and at colder temperatures than many native grasses, it may be possible to remove downy brome from desirable seed lots by exploiting germination differences. We initiated a sequence of experiments where native grass and downy brome seeds underwent a wet germination treatment followed by a drying period. During the first experiment, we evaluated three different germination temperatures (3, 6, and 12°C) for 20-days. Downy brome germinated earlier and more rapidly than native species at all temperatures. No downy brome survived the 6°C and 12°C treatments. Survival was lower for all treated seeds compared to nontreated seeds except blue grama at 3°C. We held temperature constant (6°C) in the second experiment and compared four germination treatment durations (8, 10, 12, and 14 days). Blue grama germinability was unaffected by treatment duration in the second experiment, and thickspike wheatgrass was only reduced by the 14-day treatment. Downy brome mortality was limited in the second experiment and ranged from 4.5 to 51% depending on treatment duration. In the third experiment, we compared six drying treatments after a constant germination temperature (6°C) and duration (12 days). Blue grama and thickspike wheatgrass had the highest survival compared to downy brome. Drying seeds in commercial dryers at 30°C and 60°C severely reduced downy brome survival while maintaining high blue grama survival. Results were similar for thickspike wheatgrass in the 30°C dryer.
