Book Description
Excerpt from Improving Duck Marshes by Weed Control In some plants, the ideal time for treatment shows no clear rela tion to the flowering or fruiting stages. Woody plants commonly respond best when control measures are applied in later summer or fall; giant cutgrass is killed most readily about two months after its flowering, during the period of maximum runner growth. Much remains to be learned about the ideal time for treatment of different species by different methods, and as more information is obtained on these matters control programs will improve in efficiency and economy.

Book Description
Excerpt from Natural Wild Duck Foods, 1930: Improve Your Hunting In waters where their natural food does not grow now. It can very easily be planted and the waters made attractive to the wild waterfowl. T here are important food plants for these wild waterfowl which will grow under almost every water condition that exists.

Book Description
Excerpt from Wild Ducks and Duck Foods of the Bear River Marshes, Utah It has been said in the foregoing that the supplies Of Seeds car ried over winter in the fruiting heads of the bayonet grass, or tule, are of importance as food fer the Wild ducks returning from the South in spring. AS these seeds are available practically through out the year they furnish a valuable source of sustenance. The burning of large areas, therefore to clear the marsh or to induce a fresh clean growth for ranging purposes is to be frowned upon, as it tends to destroy a certain proportion of the available stock of duck food. Many of the seeds are charred and destroyed by the flames, and though apart are not seriously harmed a largepropor tion of the'stockis. Liable to be washed away. And lost during the high water _incident to the breaking up of the winter covering of Ice In spring, and the subsequent floods due to melting snows in the foothills. While the practice of burning clears the marsh, it also destroys mats and tangles of dead vegetation that in many cases form necessary Shelters for the breeding ducks, insuring the successful hiding of their nests and later protecting the young until they are strong enough to venture into the Open.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Description
Biology and Control of Aquatic Plants: A Best Management Practices Handbook is the fourth edition of a handbook produced by the not for profit Aquatic Ecosystem Restoration Foundation (AERF). The mission of the AERF is to support research and development which provides strategies and techniques for the environmentally and scientifically sound management, conservation and restoration of aquatic ecosystems. One way the Foundation accomplishes this mission is by producing this handbook to provide information to the public regarding the benefits of aquatic ecosystem conservation and aquatic plant management. The first, second and third editions of this handbook became some of the most widely consulted references in the aquatic plant management community. This fourth edition has been specifically designed with water resource managers, water management associations, homeowners and customers and operators of aquatic plant management companies and districts in mind. Our goal in preparing this handbook is to provide basic, scientifically sound information to assist decision-makers with their water management questions.

Book Description
Named one of Vulture’s Top 10 Best Books of 2020! Leftist firebrand Fredrik deBoer exposes the lie at the heart of our educational system and demands top-to-bottom reform. Everyone agrees that education is the key to creating a more just and equal world, and that our schools are broken and failing. Proposed reforms variously target incompetent teachers, corrupt union practices, or outdated curricula, but no one acknowledges a scientifically-proven fact that we all understand intuitively: Academic potential varies between individuals, and cannot be dramatically improved. In The Cult of Smart, educator and outspoken leftist Fredrik deBoer exposes this omission as the central flaw of our entire society, which has created and perpetuated an unjust class structure based on intellectual ability. Since cognitive talent varies from person to person, our education system can never create equal opportunity for all. Instead, it teaches our children that hierarchy and competition are natural, and that human value should be based on intelligence. These ideas are counter to everything that the left believes, but until they acknowledge the existence of individual cognitive differences, progressives remain complicit in keeping the status quo in place. This passionate, voice-driven manifesto demands that we embrace a new goal for education: equality of outcomes. We must create a world that has a place for everyone, not just the academically talented. But we’ll never achieve this dream until the Cult of Smart is destroyed.

Book Description
This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
