Book Synopsis The Canada-Alberta Wetlands Drainage and Improvement for Forestry Program by : Graham Robin Hillman

This book was released on 1990 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1985, a wetland drainage and improvement for forestry program was instituted under the Canada-Alberta Forest Resource Development Agreement to determine the effects of drainage on tree growth, ground vegetation, soils, peat, and local hydrology. Three experimental areas were chosen and portions of each drained in 1986 and 1987. Data were collected from drained and undrained portions. Additional data were collected from a treed swamp near Fort McMurray that was subjected to different drainage treatments between 1975 and 1980. The intent, in this case, was to obtain an interim estimate of tree growth rates until sufficient time has elapsed to obtain estimates from permanent sample plots on the experimental areas. Results showed that the average depth to groundwater table after drainage was between 37 and 90 cm and varied with ditch spacing. The corresponding drops in water table levels were between 17 and 78 cm. The test areas with 30-m ditch spacings appeared to be overdrained. Stream water quality data from one site only have been interpreted so far. They show that drainage had little effect on measured physical and chemical stream water quality during low flows. Further analyses are required to determine the effects of drainage on peak flows. Initial results from the three experimental areas indicate that drainage has resulted in reduced ground vegetation cover (mosses, sedges and other herbs) and vigor. Lowering the water table on the swamp near Fort McMurray resulted in sigificant increases in height, diameter and volume of 30-year-old black spruce (Picea mariana). The increase in growth of black spruce was accompanied by an equally impressive growth of alder (Alnus crispa), willow (Salix spp.), birch (Betula pumila), aspen (Populus tremuloides) and balsam poplar (E. balsamifera)."--Page iii.

Book Synopsis Methods of Dendrochronology by : E.R. Cook
Download or read book Methods of Dendrochronology written by E.R. Cook and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a review and description of the state-of-the-art methods of tree-ring analy~is with specific emphasis on applications in the environmental sciences. Traditionally, methods of tree-ring analysis, or more properly in this case methods 0/ dendrochronology, were developed and used for dating archaeological and historical structures and for reconstructing past climates. The classic book Tree Rings and Climate, by H.C. Fritts, published in 1976, provided a superb introduction to the science and an in-depth description of techniques useful for extracting climatic information from tree rings. This book, which was published by Academic Press, is sadly out of print and, even though only 12 years old, lim ited in its methods and applications. This is owing to the extremely rapid development of the science since the 1970s. Only recently have tree rings as environmental sensors been fully recog nized as a valuable tool in detecting environmental change. For example, tree ring measurements have been critically important in studies of forest decline in Europe and North America. There are also attempts to use tree-ring analysis for ecological prognosis to solve large-scale regional problems including the sustain ability of water supplies, prediction of agricultural crops, and adoption of silvi cultural measures in response to ecological changes. More speculatively, dendro chronological methods are also used for dating and evaluating some astrophysical phenomena and for indicating possible increase in the biospheric carrying capac ity due to increased atmospheric carbon dioxide.
Book Synopsis Ecological Regions of North America by :
Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Book Synopsis Tree Rings and Climate by : H Fritts
Download or read book Tree Rings and Climate written by H Fritts and published by Elsevier. This book was released on 2012-12-02 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree Rings and Climate deals with the principles of dendrochronology, with emphasis on tree-ring studies involving climate-related problems. This book looks at the spatial and temporal variations in tree-ring growth and how they can be used to reconstruct past climate. Factors and conditions that appear most relevant to tree-ring research are highlighted. Comprised of nine chapters, this book opens with an overview of the basic biological facts and principles of tree growth, as well as the most important terms, principles, and concepts of dendrochronology. The discussion then shifts to the basic biology governing the response of ring width to variation in climate; systematic variations in the width and cell structure of annual tree rings; and the significance of tree growth and structure to dendroclimatology. The movement of materials and internal water relations of trees are also considered, along with photosynthesis, respiration, and the climatic and environmental system. Models of the growth-climate relationships as well as the basic statistics and methods of analysis of these relationships are described. The final chapter includes a general discussion of dendroclimatographic data and presents examples of statistical models that are useful for reconstructing spatial variations in climate. This monograph will be of interest to climatologists, college students, and practitioners in fields such as botany, archaeology, hydrology, oceanography, biology, physiology, forestry, and geophysics.
