Book Description
The distribution of lodgepole pine and jack pine stands severely damaged by lodgepole pine dwarf mistletoe, Arceuthobium americanum Nutt. Ex Engelm., is described for Alberta, Saskatchewan, and Manitoba. The distribution of affected stands is based on aerial and ground surveys of jack (Pinus banksiana Lamb.) and lodgepole pone (P. contorta Dougl, ex Loud. var latifolia Engelm.) forests conducted between 1984 and 1996. Depending on method of determination, between 455 000 and 585 000 ha of jack pine forests and 80 000 - 85 000 ha of lodgepole pine forests were severely diseased by dwardf mistletoe. These areas account for about 5% of the total area of pine in the study area. Annual losses due to reductions in growth and tree mortality were estimated at 2 347 000 m3. Most diseased jack pine stands occurred in the Boreal Plains ecozone, while diseased lodgepole pine stands occurred approximately equally in both the Boreal Plains and the Montane Cordillera ecozones. The report includes maps and a CD-Rom containing an Arc/Info export-format file of the coverage of pine areas severely damaged by dwarf mistletoe in west-central Canada.
