Download or read book Forest Insect- and Disease-caused Impacts to Timber Resources of West-central Canada, 1988-1992 written by James Peter Brandt and published by Canadian Forest Service, Northern Forestry Centre. This book was released on 1995 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes the impacts caused by major forest insects (defoliators and bark beetles) and diseases (excluding those caused by fungi) to the timber resources of the Prairie Provinces and Northwest Territories in terms of wood volume losses due to tree mortality and growth reduction for the 1988-92 period. Most impacts were calculated using an automated system based on defoliation or infestation maps produced by geographic information systems and related inventory data. Results are presented for losses due to the following: spruce budworm (Choristoneura fumiferana), jack pine budworm (C. pinus pinus), forest tent caterpillar (Malacosoma disstria), large aspen tortrix (C. conflictana), bruce spanworm (Operophtera bruceata), mountain pine beetle (Dendroctonus ponderosae), spruce beetle (D. rufipennis), Douglas-fir beetle (D. pseudotsugae), Lodgepole pine dwarf mistletoe (Arceuthobium americanum), and wood decay.

Download or read book Historical Patterns of Spruce Budworm Defoliation and Bark Beetle Outbreaks in North American Conifer Forests written by David W. Williams and published by . This book was released on 2003 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This atlas presents maps of historical defoliation by the eastern and western spruce budworms and historical outbreaks of the mountain and southern pine beetles during the past half century. The maps encompass various regions of the conterminous United States and eastern Canada. This publication also serves as documentation for an extended set of digital maps, which are available on our website. The digital maps are useful for investigating spatial dynamics of insect populations and for providing pest disturbance inputs to spatially explicit forest simulation models.

Download or read book Ecosystem Management in the Boreal Forest written by Sylvie Gauthier and published by PUQ. This book was released on 2009 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.

Brief descriptions are given of major forest disturbances in the region, including forest tent caterpillar defoliation, lodgepole pine dwarf mistletoe infestation, spruce budworm defoliation, and forest fires. Current climatic data from across the region are compared to 30-year normals for a number of parameters. Details of the assessments completed on the 17 permanent biomonitoring plots are also presented, and the state of regeneration on the plots is discussed. In addition, the current status of quarantine pests in Canada of concern to the forestry sector is described.
