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
In the fall/winter of 1987 a project was begun to determine if the measured rate of change in sugar maple tree conditions is related to various levels of pollution, managed sugarbush vs. undisturbed stands, or various levels of initial stand decline conditions; the possible causes of sugar maple decline; and the geographical relationships between causes and the extents of decline. This report summarizes the results of the 1988 field season.
