Download or read book Natural Regeneration of Hardwood and Softwood Tree Species Following Full-tree Harvesting in Northwestern Ontario written by Edward S. Symons and published by . This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents results of a study that describes the stand structure and composition of selected full-tree harvested sites about ten years after harvest, with examination of evidence for ingress of natural regeneration. Sampled sites were stratified by seedbed condition and the pre-harvest vegetation type they supported; seedbeds were classified as either intact/mixed forest floor or scalped/mineral soil exposed. Vegetation types were amalgamated into ecologically similar groups or treatment units. Most sites were classified as black spruce-jack pine/feathermoss with intact/mixed forest floor seedbeds. Both the rate of natural ingress over the first seven years of stand development and the resultant stand structure and composition are noted.
Book Synopsis Ingress of Natural Regeneration in Plantations After Tree-length Harvest in Northwestern Ontario by : Colin Leslie Bowling
Download or read book Ingress of Natural Regeneration in Plantations After Tree-length Harvest in Northwestern Ontario written by Colin Leslie Bowling and published by [Thunder Bay] : Ontario Ministry of Natural Resources, Northwest Science & Technology. This book was released on 1997 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarizes results of a study conducted to investigate species composition, stand structure, and rate of ingress of natural regeneration during the first 20 years following clear-cutting by the tree-length logging method in north- western Ontario. In 1990 and 1991, 96 plantations in that region were assessed, with the following data collected for planted trees and natural regeneration: tree species, site, seedbed type, height, and density. Some plots were destructively sampled to determine total tree age in order to estimate the rate of ingress of natural regeneration. Results have relevance for predicting the probability of occurrence and density of natural regeneration, and for the timing of regeneration surveys.

Download or read book Dynamic Forest written by Malcolm F. Squires and published by Dundurn. This book was released on 2017-08-26 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearing the end of a lifetime in the boreal forest, a retired forester writes a passionate plea for rational, science-based forest management. The boreal forest is constantly changing, often dramatically. We like to picture it as a stable, balanced system. Really, it is anything but stable. The boreal forest is dynamic. For over sixty years, forester Malcolm F. Squires has seen mature forests within protected areas devastated by insects, moose, wind, and wildfire. While the forests often return from this destruction, they are never quite the same. A naturally balanced boreal forest is a human notion that does not match the reality of nature. If we don’t soon recognize and accept that reality and stop making irrational demands that a forest be “protected” from change or human management, we may be dooming them to disaster.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For managed forests which rely on natural tree regeneration for canopy recruitment, abundance and composition of tree regeneration portend future forest structure and diversity. For northern hardwood forests, a geographically widespread forest type in North America, typical single-tree selection (STS) management relies on natural regeneration to promote new cohorts of canopy trees. Harvesting dispersed, select trees every 15 - 20 years, STS generates low light levels intended to promote sugar maple (Acer saccharum) and other shade-tolerant tree species in an uneven-aged system. However, following 60 + years of STS implementation in the Great Lakes region, concerning regeneration trends have emerged, namely low densities of sugar maple and low tree species diversity. Additionally, few studies have analyzed age structure under this system to assess its past efficacy in generating uneven-aged forests. The research presented here characterizes regeneration and recruitment outcomes of STS, analyzing data from a uniquely detailed and geographically widespread research project of 141 northern hardwood stands across northern Michigan.Given the silvicultural focus on regenerating sugar maple, the first two chapters focus on management outcomes for this key species. First, a flexible Bayesian hierarchical model offers insight on patterns of sugar maple regeneration for key size classes as a function of plot and stand level predictors. Our results indicate that sugar maple regeneration is sparse to absent, particularly for size classes actively browsed by deer and recently escaped from the deer browsing zone. The second analysis characterizes age structure for a subset of 51 stands, drawing on 1499 sugar maple trees > 5 cm diameter sampled via basal discs from recently harvested stumps; this analysis provides insight to past patterns of recruitment and establishment. The results suggest little evidence of sugar maple seedling regeneration and canopy ingrowth over the past 60 + years of STS management; instead, stands have highly suppressed saplings plus aging poletimber and sawtimber classes, which are at or quickly approaching economic maturity. Given declines in sugar maple dominance as evidenced by the first two research analyses, the third analysis assesses stand-level tree species diversity and individual species abundance as a function of landscape predictors and size class to shed light on projected future canopy composition. On average, there are approximately three effective common species for seedlings, saplings, and canopy stems at the stand level, and species less desirable for management are occupying growing space in the sapling layer.Together, these results indicate that STS has been unsuccessful in regenerating or recruiting sugar maple over the past 60 + years, and stands are characterized by a paucity of tree species. Our results support several potential alternative management strategies, including decreasing basal area via more intense harvests, prohibiting deer browsing via natural browsing barriers, or introducing greater diversity of tree species via direct seeding or planting. These results should be considered to improve current management of northern hardwood forests in the Great Lakes region.

Book Synopsis The CABI Encyclopedia of Forest Trees by : CABI
Download or read book The CABI Encyclopedia of Forest Trees written by CABI and published by CABI. This book was released on 2013 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CABI Encyclopedia of Forest Trees provides an extensive overview of 300 of the world's most important forest trees. Tropical, subtropical, temperate and boreal trees of major economic importance are included, covering tree species used in agroforestry practices around the world. Many of the species covered are considered to be multipurpose trees with uses extending beyond timber alone; the land uses such as watershed protection or provision of windbreaks, and non-wood uses such as the production of medicines, resins, food and forage, are also listed. Comprehensive information is presented on each tree's importance, with a summary of the main characteristics of the species, its potential for agroforestry use and any disadvantages it possesses. The tree's botanical features such as habit, stem form, foliage, inflorescence, flower and fruit characters and phenology are covered in detail with over 70 color plate pictures to aid identification. Also included are specific sections devoted to pests and diseases, distribution and silvicultural characteristics and practices, including seed sowing, nursery care, planting, thinning, and harvesting. In addition to the wealth of information detailed, based on datasheets from CABI's Forestry Compendium, selected references for further reading are provided for each entry, making this book an essential reference work for forestry students, researchers and practitioners.
