Download or read book Wind Damage in a Partially Harvested Boreal Mixedwood Stand in Northeastern Ontario written by James A. Rice and published by . This book was released on 2011 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the study was to test a series of innovative silvicultural treatment packages designed to create mixtures of hardwoods and conifers while monitoring changes in ecological and silvicultural indicators of sustainability. The effects of wind damage on residual trees were monitored at the Stand Level Adaptive Management (SLAM) study site east of Cochrane, Ontario. The goals of this component of the study were to quantify and compare the effects of wind damage between partially harvested and unharvested portions of stands after harvest and to determine their influence on achieving the silvicultural objectives of the partial harvest treatment. Here the authors report the amount and distribution of wind damage in the residual stands at 1, 2, and 4 years after harvest and discuss the effects of this damage on the potential to achieve the desired silvicultural objectives. Specifically, they were interested in the effects of harvest treatments, tree species, direction of fall, stem rot, and stem form on the number and percent of wind damaged trees.--Document.

Download or read book Alternative Silvicultural Systems for Ontario s Boreal Mixedwoods written by Christopher Herbert Richard Wedeles and published by Sault Ste. Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1995 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarises the potential use of alternative silvicultural (harvesting) systems on the productivity of boreal mixedwood forests. Begins with an overview of the ecology of boreal mixedwoods, including physical environment, stand dynamics, and landscape ecology; then provides detailed reviews of modified clear-cutting systems (including strip cutting, patch cutting, and seed-tree cutting), shelterwood systems, and selection systems (including group selection and individual tree selection). Also briefly discusses the environmental considerations that are associated with these systems (effects on soil, water resources, wildlife, and aesthetics). Concludes with a discussion of areas of uncertainty in the application of alternative systems and the perceived problems that have limited their use in boreal mixedwoods.

Southcentral Science Section and published by North Bay : Ontario Ministry of Natural Resources, Southcentral Sciences Section. This book was released on 1999 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesizes the published literature on the following: the ecological and possible economic effects of ice storms on natural forests and plantations, including where possible the influences of past management practices; the recovery and mortality of individual trees and forests after ice storm damage; and management recommendations for ice damaged woodlots and plantations to minimize negative impacts. The literature search also superficially considered: wind and snow damage; some of the biological functions of tree reaction to wounds, crown damage, defoliation, and increased exposure; and disease and insect implications.

Available in PDF, EPUB and Kindle. Book excerpt: "This bibliography includes a list and descriptions of the content of publications written or co-authored by staff of the Ontario Ministry of Natural Resources' Ontario Forest Research Institute between 2006 and 2010. During this five-year period, over 150 publications were produced by the institute's 14 research scientists, including a book, 83 journal articles, 31 reports, 10 technical notes, 5 newsletters, and 11 papers/summaries in conference/ workshop proceedings. The overall focus of the publications is forest resource management-related research and practice. Topical areas and scales of investigation are diverse and include natural disturbance regimes and landscape dynamics; carbon budgets and effects of climate change on forests; and silviculture studies on site preparation, tree improvement, vegetation management, growth and yield, disease management, and harvesting in conifer, mixedwood, and hardwood forests. Author and subject indexes are provided."--Document.

Download or read book Ecology and Conservation of Forest Birds written by Grzegorz Mikusiński and published by Cambridge University Press. This book was released on 2018-03-29 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.

Available in PDF, EPUB and Kindle. Book excerpt: This weather guide includes detailed specifications for locating and instrumenting fire weather stations, taking weather observations, and overwintering the Drought Code component of the FWI System. The sensitivity of the FWI System components to weather elements is represented quantitatively. The importance of weather that is not directly observable is discussed in the context of fuel moisture and fire behavior. Current developments in the observation and measurement of fire weather and the forecasting of fire danger are discussed, along with the implications for the reporting of fire weather of increasingly automated fire management information systems.

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.
