Summarizes 1996 results of forest health monitoring activities in Alberta, Saskatchewan, Manitoba, and the Northwest Territories, based on assessments made on 17 permanent biomonitoring plots and assessments of major forest disturbances. 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.

Although forest health may be difficult to define and measure, a strong demand exists for assessment of forest conditions at various state, regional, and national scales. Forest Health Monitoring (FHM) is a national program designed to measure the status, changes, and trends of forest conditions annually. This report presents a broad view of forest health issues affecting the Interior West region of Montana, Idaho, Wyoming, Utah, Nevada, Colorado, New Mexico, and Arizona. We found that the forests of the Interior West have changed considerably in the past century. What is more difficult to assess is whether humans have promoted change that is irreversible, or whether the change we see in the forested landscape is within healthy bounds. Discussions of forest health and forest cover change, the developed and wildland interface, insect and disease disturbances, watershed health, biodiversity, and air quality comprise the body of this report. This initial report sets the stage for more in-depth reports on forest health in the Interior West by introducing the FHM program, defining "the forest" regionally, discussing prominent issues, and displaying summary FHM data taken from 1996-1999. A website address is provided on the inside back cover of this report to solicit reader suggestions for improving future FHM reports.

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.

This Special Issue of Water, Air and Soil Pollution offers contributions from the th 18 IUFRO workshop on Air Pollution Stress, Forest Responses to the Pollution st Climate of the 21 Century held in Edinburgh, Scotland, from September 21 to 23,1998. The meeting was held under the auspices of IUFRO, Research Group 7.04.00 chaired by Dr Kevin Percy of Canada. A new session structure was adopted to stimulate activity within the six working parties and a brief resume of these is presented at the front of this volume. The two, one-day plenary sessions were devoted to the two important air pollution issues, nitrogen deposition and ozone. Invited papers were augmented by a large and excellent contribution of poster papers. The final day comprised parallel Working Party Sessions with pre arranged speakers to stimulate discussions. One hundred and thirty one scientists attended, representing 20 countries and 7 IUFRO regions: Northern Europe, Central Europe, Eastern Europe, Mediterranean, North America, Asia and the Western Pacific.
