Available in PDF, EPUB and Kindle. Book excerpt: The "International Symposium on Scleroderris Canker of Conifers" held June 21-24, 1983 in Syracuse, New York was the result of mutual interest expressed by the USDA Forest Service, the Canadian Forestry Service, and the State Uni versity of New York College of Environmental Science and Forestry (SUNY ESF). The Symposium was an official function of the working party canker diseases (Scleroderris), Subject group S.2.06.02 Division II IUFRO. We wish to express our thanks to the USDA Forest Service, Research and the Canadian Forestry Service for financial support of the program, and SUNY ESF for hosting the Symposium. A major research program was launched in 1977 to study the biology of the European strain as found in North America. Support for this research resulted from spec i a 1 fund ing by the Congress of the United States to the USDA Forest Service, North Central Forest Experiment Station. Most of these funds were released as cooperative research grants to universities in the Lake States and the northeast. Many of the research papers delivered at this Symposium are the direct result of these research grants. While the Symposium deliberately emphasized the North American experience 'with Gremmeniella abietina in order to provide a focus for the meeting, we were anxious that this Symposium would also include studies from other countries.

This book was released on 2013-06-29 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threats posed by air pollution and climate change have resulted in considerable public debate about forest condition and growth during the past two decades. Despite the massive input ofresearch resources, no clear answers have been found to these global questions. Although there have been substantial advances in our knowledge of the effects of air pollutants on the forests, many of the questions associated with forest condition are still open. Monitoring of forest condition at the national level started in Finland in 1985 in accordance with the methodology drawn up by the International Co-operative Programme on Assessments and Monitoring of Air Pollution Effects on Forests (ICP Forests, UN/ECE). Since then, research into forest condition and vitality has been one of the key areas in the research carried out by the Finnish Forest Research Institute. Three basic questions formed the starting point for the multidisciplinary, Forest Condition Research Programme: What changes are taking place in our forests? Why does forest condition vary, and why do trees appear to be suffering? How can forest condition be maintained through appropriate forest management? This report covers forest condition and changes in environmental factors on the of the latest findings, publications and expertise of researchers participated in basis the Forest Condition Research Programme. In addition to researchers from the Finnish Forest Research Institute, a large number of scientists from domestic and foreign universities and research institutes also made a considerable contribution to the research programme.
