Book Description
The current mountain pine beetle (MPB) outbreak exceeds any recorded infestation and is considered a threat to pine species in the boreal and eastern Canadian forest ecosystems. Previous studies have shown that moderate weather and successful fire suppression create prime conditions for MPB growth, which is affecting novel forest habitat. From 2008 to 2010, the Canadian Forest Service (CFS) conducted late spring surveys of MPB infestations in the Peace Region of British Columbia to determine changes in population and infestation levels based on attack and brood densities in infested trees. During 2009 and 2010, similar data was collected by the Alberta Sustainable Resource Development (SRD) on post-winter MPB survival in north-central Alberta. Overwintering population success was determined based on two rating systems of R-values: the Canadian Forest Service Forest Insect and Disease Survey (FIDS) system of the CFS, and the SRD system. R-value was calculated by summing all live mountain pine beetles of various life stages for every plot. The British Columbia and Alberta survey data (the R-values) were combined to determine the distribution of overwintering population success. During 2009 and 2010, the overwintering MPB population success in the Peace Region of British Columbia and adjacent Alberta was based on interpolated maps of SRD ratings of infestations. For comparison, a map for each rating system was created from the 2010 surveys of British Columbia and Alberta.

Publisher:
ISBN:
Category : Forest insects
Languages : en
Pages : 40
Book Description
Forest pest conditions in Alberta, Saskatchewan, Manitoba, and the Northwest Territories during 1989 are summarized and some predictions of infestation status are given for 1990. Eleven major pests are discussed, and additional noteworthy insects, diseases, and tree damage agents are reported in a table.

The Mountain Pine Beetle
Author: Pacific Forestry Centre
Publisher:
ISBN: 9780662426233
Category : Forest management
Languages : en
Pages : 304
Book Description
"This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.
