The Acid Rain National Early Warning System (ARNEWS) plot network was initiated in 1984 when the then Canadian Forestry Service decided to establish a national program to detect early signs of air pollution damage to Canada's forests. Since that time, more than 150 ARNEWS plots have been established across Canada to monitor changes in forest vegetation and soils caused by air pollution and environmental change. More than 10 000 trees are currently monitored in the ARNEWS plot network. All components of ARNEWS methods were revised with three objectives in mind: practicality, meaningfulness, and repeatability. Components such as plot establishment guidelines, protocols for collecting general mensuration data, soil analysis methods, analysis of tree condition, and assessments of ground vegetation and regeneration were all examined closely and revised where necessary. Numerous new figures are appended to describe parameters and to provide examples of procedures to follow for abnormal situations. Appendices have been attached listing tree species codes and summarizing other code values used. Codes were synchronized with other studies conducted by the Forest Insect and Disease Survey.
