Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Chestnut, a Bibliography: A Bibliography of References to Castanea Dentata and Other Chestnut Species, and on Chestnut Blight and Its Causal Pathogen of the Fungal Genus Endothia or Cryphonectria In working with a bibliography over a period of 12 years, trends in research and publication become apparent. Jean Q. Wade carefully tabulated the entries by time period and subject, providing the data for a few observations here: The interest in fungi, particularly pathogens, was strong in the 19th Century and continues today. In contrast, nucleic acid and other biochemical studies are relatively recent. In the early blight period, there was a major effort to understand the life cycle, spread, and pathogenic action of the blight fungus. There has been only one attempt to summarize the history of the blight and research related to the blight, Fifty years of Chestnut Blight in America (beattie and Diller, They observed that, All of the cooperative work (among Federal and State scientists) slowed and almost came to a close in 1914 and 1915 when chestnut blight appropriations were greatly reduced. The organizations were broken up and the men scattered to do other work. The attempt to understand and stop the blight was meager. From 1906 to 1910, (while the disease was spreading north, south, and west from New York City), only a few hundred dollars a years of Federal money were In that year (1911) Congress appropriated In 1912 an appropriation of was made, and this was repeated the following the Pennsylvania legislature appropriated for the 1913-14 biennium (beattie and Diller.

Book excerpt: Excerpt from Federal Domestic Plant Quarantines: March 1965 Certain plant diseases, insects, and other destructive plant pests cost the people of this country more than $7 billion a year due to their damage and money spent to control them. Most of this loss is chargeable to alien pests and diseases, many of which came to this country before our Federal quarantine laws were enacted. The European corn borer, for example, probably got into this country in 1910 on imported broomcorn. It now infests too vast an area for-an effective quarantine effort. Chestnut blight, a fungus disease from Asia, has killed almost all of our na tive chestnut trees. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Ecology of a Managed Terrestrial Landscape written by Ajith H. Perera and published by UBC Press. This book was released on 2011-11-01 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing popularity of the broad, landscape-scale approach to forest management represents a dramatic shift from the traditional, stand-based focus on timber production. Ecology of a Managed Terrestrial Landscape responds to the increasing need of forest policy developers, planners, and managers for an integrated, comprehensive perspective on ecological landscapes. The book examines the "big picture" of ecological patterns and processes through a case study of the vast managed forest region in Ontario. The contributors synthesize current landscape ecological knowledge of this area and look at gaps and future research directions from several points of view: spatial patterns, ecological functions and processes, natural disturbances, and ecological responses to disturbance. They also discuss the integration of landscape ecological knowledge into policies of forest management policies, particularly with respect to Ontario's legislative goals of forest sustainability. Ecology of a Managed Terrestrial Landscape is the first book to describe the landscape ecology of a continuously forested landscape in a comprehensive manner. It is written for instructors and students in forest management, wildlife ecology, and landscape ecology, and for forest managers, planners, and policy developers in North America.
