Download or read book White Pine and Red Pine Volume Growth Under Uniform Shelterwood Management in Algonquin Provincial Park written by G. D. Puttock and published by Sault Ste Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1995 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Outlines the development and use of a compatible growth and yield model for red pine and white pine stands under a uniform shelterwood silvicultural system in Algonquin Provincial Park, Ontario. The model incorporates stand age, residual (post-harvest) basal area, site index, composition index (proportion of pine basal area), and projected age as predictor variables for estimating residual gross merchantable pine volume and for projecting basal area and gross merchantable pine volume growth over a given time period. Model results are presented for periods up to 25 years following uniform shelterwood harvesting and for stand ages of 40 to 130 years. The appendix contains yield curves and yield tables.
Download or read book A Silvicultural Guide for the White Pine and Red Pine Working Groups in Ontario written by David John Chapeskie and published by . This book was released on 1989 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This silvicultural guide is one of several, each of which provides a description of the silvicultural characteristics of the working group species and describes silvicultural practices for the working group. The guide reflects relevant literature and research, and the knowledge and experience of forestry staff in the management of the working group in Ontario and elsewhere. The guide covers the range and commercial importance of white pine and red spruce, siting, and wildlife and environmental considerations. Management prescriptions include such silvicultural systems as shelterwood and clear cut systems, harvesting considerations, forest renewal, stand maintenance, conversion and management intensity. Data is also given on the age-class distribution, historical harvest, average roundwood receipts, and biological rotation ages.

Book excerpt: The growth, regeneration, and quality of white pine between the 1970's and 1980's were analyzed for the six-state New England region. Growth was comparable among all states except for Rhode Island where the growth (1.71%) was low in comparison with other states and with the growth of red maple (4.29%) within the state. For all states, the proportion of acreage in white pine seedling/sapling stands was too small (8%) to maintain the current volume and acreage of the species. However, stems in the 2- to 10-inch diameter class were adequately J-shaped over all states to sustain the species. Because many of these small stems must be in small openings or under partial canopies, efforts to regenerate and release white pine seem warranted. The percentage of volume in grades 1 and 2 more than doubled between the 1970's and 1980's in all states except Massachusetts and Connecticut where the percentage remained about constant.

Marie : Ontario Ministry of Natural Resources. This book was released on 1995 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigators determined the age, mode of regeneration, and diameter growth of white pine in an old growth stand near Dividing Lake, Algonquin Provincial Park. This report presents preliminary results of the investigation, conducted as part of a study to construct ring-width chronologies and to evaluate the role of fire in pine ecosystem regeneration. The results include age distribution, period of regeneration, regeneration class, and correlation between age and growth rate.

Download or read book Growth Responses in Individual Eastern White Pine Pinus Strobus L Trees Following Partial Cutting Treatments written by Eddie Bevilacqua and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: White pine ('Pinus strobus' L.) growth following a partial cutting treatment was analyzed to assess the growth response of individual trees from three different crown classes to varying levels of local neighbourhood competitive interference. Trees from all crown classes, with an average age of 69 years, showed increased rates of diameter, basal area and volume growth following release. Only intermediate trees responded with increased height growth. Specific volume increment (SVI) proved superior to relative growth rate for assessing competition effects on size-dependent volume growth by virtue of its greater sensitivity to and better correlation with indices of competition. Significant differences in SVI among crown classes in both released and control treatments 23 years after release were observed. Released trees had increased levels of SVI for the first 15 years following treatment. The hypothesis of size symmetry in resource competition was rejected by virtue of the stronger relationship between SVI and competition indices that weighted competitors by relative size. However, two-sided competition could not be rejected in view of the significant influence of smaller trees on SVI of larger trees. No difference between intra- and inter-specific competition on white pine growth was detected. Plasticity in growth form was evident. Intermediate trees exhibited significantly different crown and stem form among crown classes in the control treatment, and different crown form relative to the release treatment. Crown size, which was positively correlated with volume increment, improved as a result of competition release and was inversely correlated with levels of local neighbourhood competition. Vertical distribution of bole area increment in all crown classes was altered in the release treatment. Bole area increment in released trees increased progressively from tree apex to base of the stem for the first 15 years after partial cutting, eventually resulting in significant changes in stem form. Control trees showed relatively constant area increment below the crown with no significant change in stem form. A cumulative volume growth model based on initial tree size, age, and local neighbourhood competition was developed for use in white pine stands managed under a partial cutting regime, such as the uniform shelterwood system.
