Book Description
The Acid Rain National Early Warning System (ARNEWS) was established in 1984 to detect early signs of damage to Canadian forests and to monitor changes in forest vegetation and soils. In this document, the number of trees that died in 1995 is reported, in addition to the historical mortality rate for major species. The cause of tree mortality is also determined in the field, using nondestructive techniques, and when necessary supplemented by laboratory examination.

Book Description
The current rate and scale of environmental change around the world makes the detection and understanding of these changes increasingly urgent. Subsequently, government legislation is focusing on measurable results of environmental programs, requiring researchers to employ effective and efficient methods for acquiring high-quality data. Envi

Book Description
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.

Book Description
In July 2006, more than 170 researchers and managers from the United States, Canada, and Mexico convened in Boulder, Colorado, to discuss the state of the science in environmental threat assessment. This two-volume general technical report compiles peer-reviewed papers that were among those presented during the 3-day conference. Papers are organized by four broad topical sections--Land, Air and Water, Fire, and Pests/Biota--and are divided into syntheses and case studies. Land topics include discussions of forest land conversion and soil quality as well as investigations of species' responses to climate change. Air and water topics include discussions of forest vulnerability to severe weather and storm damage modeling. Fire topics include discussions of wildland arson and wildfire risk management as well as how people precieve wildfire risk and uncertainty. Pests/biota topics include discussions of risk mapping and probabilistic risk assessments as well as investigations of individual threats, including the southern pine beetle and Phytophora alni. Ultimately, this publication will foster exchange and collaboration between those who develop knowledge and tools for threat assessment and those who are responsible for managing forests and rangelands.
