Download or read book Growth of Interior Spruce Seedlings on Forest Floor Materials written by Jeanette Lynne Heineman and published by . This book was released on 1991 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: On a site with a high water table and thick forest floor near Smithers, B.C., two year-old Interior spruce (Picea glauca (Moench) Voss X Picea engelmanni Parry) container seedlings were outplanted onto mineral soil, H-layer material, F-layer material, and rotten wood. Large and small screef sizes were utilized. Temperature and volumetric water contents of the various substrates were monitored over the 1989 growing season, and fertilization with NH4NO3 was carried out at the beginning of the 1990 growing season. Destructive sampling of the seedling population took place in August 1989 and August 1990 in order to determine height, root collar diameter, root mass, shoot mass, total seedling mass, and shoot to root ratio. Foliar N concentrations were also determined in late August 1990. Differences in height and diameter for the seven screef size/substrate treatments were not significant, but the organic substrates produced seedlings of greater root, shoot, and total seedling mass than did mineral soil. Greater seedling mass was correlated most strongly with higher substrate temperature, and to a lesser extent with lower soil moisture content, as well as with higher foliar N concentration. There were no significant differences in survival between the treatments. Seedlings growing in the organic substrates had higher foliar N levels, and fertilization improved growth for all parameters. It is concluded that on sites such as this, better growth results can be achieved by planting Interior spruce seedlings high above the water table in F-layer material, where conditions are warmer and drier, than by making deep screefs down to more traditionally acceptable planting substrates such as mineral soil or even the well decomposed H-layer material.

Download or read book Synopsis of Information on White Engelmann and Black Spruce Natural Regeneration in North America written by Everett B. Peterson and published by . This book was released on 1994 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report providing a subjective assessment of the scope, applicability, and overall reliability of existing published references related to natural regeneration of white, Engelmann, and black spruce in North America and a synopsis of references on the subject. The references are listed alphabetically by author for each of 563 references, based on a dBASE IV database coded according to 105 keywords. The database allows the user to search geographically, by species of spruce, by forest section within Canada, or by any of the keywords listed. The emphasis is on white spruce in a boreal mixedwood setting but also includes information on natural regeneration of Engelmann spruce and upland black spruce, plus a limited amount of Norway spruce. Most of the references are from the 1990s.

Download or read book Forest Ecosystems in the Alaskan Taiga written by K. van Cleve and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The information presented in this book is the result of combined research efforts of scientists at the University of Alaska, Fairbanks, the Institute of Northern Forestry, USDA Forest Service, and the Systems Ecology Research Group, San Diego State University. The objective of the volume is to present a synthetic overview of structure and function of taiga forest ecosystems in interior Alaska. The data base for this work has appeared in earlier published articles including the special issue of the Canadian Journal of Forest Research Volume 13:5 (1983). Stimulus for this book was a conference held in Fairbanks from June 10-14, 1983. The papers presented at the conference were fore runners of the chapters in this book. We invited 19 scientists from North America and England to critique our research and synthesis efforts. Six of these people were asked to write introductory chapters for each section of the book. Formal presentation sessions, combined with field trips to research sites, introduced the invitees to the primary and secondary successional ecosystems with which we were dealing. A major wildfire, only 24 km from the University campus, was contained the week prior to the conference and one field trip provided graphic evidence of fire impact in subarctic forests. The conference conveners regretted that it was not possible to host a similar meeting during synthesis efforts in mid-January.

Download or read book Productivity of Western Forests written by and published by . This book was released on 2005 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: In August 20-23, 2004, a conference was held in Kamilche, WA, with the title S2Productivity of Western Forests: A Forest Products Focus. S3 The meeting brought together researchers and practitioners interested in discussing the economic and biological factors influencing wood production and value. One of the underlying assumptions of the meeting organizers was that management activities would be practiced within a framework of sustaining or improving site productivity; thus, several papers deal with methods to protect or improve productivity or discuss new studies designed to test the effects of various practices. This proceedings includes 11 papers based on oral presentations at the conference, 3 papers based on posters and 2 papers describing the Fall River and Matlock Long-Term Site Productivity study areas visited on the field tours. The papers cover subjects on forest harvesting activities, stand establishment, silviculture, site productivity, remote sensing, and wood product technologies.
