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.
Book Synopsis Natural Regeneration of Hardwood and Softwood Tree Species Following Full-tree Harvesting in Northwestern Ontario by : Edward S. Symons
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 Dynamic Forest by : Malcolm F. Squires
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.

Book Synopsis The Role of Insectivorous Birds in Forest Ecosystems by : James G. Dickson
Download or read book The Role of Insectivorous Birds in Forest Ecosystems written by James G. Dickson and published by Elsevier. This book was released on 2012-12-02 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Role of Insectivorous Birds in Forest Ecosystems is a publication of the proceedings of The Role of Insectivorous Birds in Forest Ecosystems symposium, held on July 13 and 14, 1978 at Nacogdoches, Texas. The proceedings discuss the ecology of insectivorous birds and acknowledge their roles in forest ecosystems. The book begins with an introduction to and history of insectivorous birds and their roles in forest ecosystems. It then discusses the sampling methods for bird and insect populations, bird foraging strategies, and ecology of insectivorous bird species and communities. This book will be helpful to forest managers in managing insectivorous birds. It is also especially valuable in formulating biological control strategies for use in forests.

This book was released on 1993 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.
