Book excerpt: This guidebook is intended to assist field practitioners in determining forest health issues and the incidence of forest health factors in high-hazard forest ecosystems. The first section describes the attributes of hazard & risk rating and briefly outlines some available hazard & risk rating systems. Section two covers forest development plan-level surveys, and includes procedures for landscape-level forest health factor surveys. Topics covered include aerial overview surveys, classification of damage, map processing, survey for pest incidence, and windthrow risk evaluation. The final section reviews stand-level surveys. Appendices include a glossary, example inventory data & field data forms, and a table of damage agents & associated pest severity ratings.

Available in PDF, EPUB and Kindle. Book excerpt: Regenerating British Columbia's Forests will assist those responsible for planning reforestation projects to reach informed decisions and will challenge them to consider primarily the biological factors basic to reforestation success rather than short-term costs and production technology. Although its main audience is practising foresters and forestry students of British Columbia, the text will be of considerable interest to foresters in other parts of Canada, the United States, and Europe who manage reforestation.

This book was released on 2019-03-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect pests. New pressures in this century are putting even more trees at risk. Expanded human mobility and global trade are providing pathways for the introduction of nonnative pests for which native tree species may lack resistance. At the same time, climate change is extending the geographic range of both native and nonnative pest species. Biotechnology has the potential to help mitigate threats to North American forests from insects and pathogens through the introduction of pest-resistant traits to forest trees. However, challenges remain: the genetic mechanisms that underlie trees' resistance to pests are poorly understood; the complexity of tree genomes makes incorporating genetic changes a slow and difficult task; and there is a lack of information on the effects of releasing new genotypes into the environment. Forest Health and Biotechnology examines the potential use of biotechnology for mitigating threats to forest tree health and identifies the ecological, economic, and social implications of deploying biotechnology in forests. This report also develops a research agenda to address knowledge gaps about the application of the technology.

Download or read book Forest Health and Mortality of Advance Regeneration Following Canopy Tree Mortality Caused by the Mountain Pine Beetle written by Kathy J. Lewis and published by . This book was released on 2011 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: "British Columbia is amid the largest recorded mountain pine beetle outbreak in North American history. To minimize timber losses, large-scale salvage operations are underway to utilize the merchantable pine. However, large-scale salvage operations can have negative impacts on a variety of forest values, including the potential to diminish mid-term timber supply opportunities. One option is to reserve stands with adequate advance regeneration for the mid-term timber supply. Another option is to salvage harvest dead trees in a way that protects the advanced regeneration. However, the health, vigour, form, and mortality rate of advance regeneration, through time, has not been well studied. To incorporate these stands into timber supply analyses and subsequent management decisions regarding reservation, mortality and forest health factors must be evaluated. We assessed the forest health of 90 residual stands over a range of stand types with varying lengths of time since attack by mountain pine beetle (MPB). Analysis of the forest health survey data showed that current damage from forest health agents was relatively low. Physical damage was the most common issue, but even in that case, the incidence ranged from
