The perceived health of forest ecosystems over large temporal and spatial scales can be
strongly influenced by the frames of reference chosen to evaluate both forest condition and …

Critical loads of acidity were estimated for upland forests in Eastern Canada using the
steady-state Simple Mass Balance (SMB) Model. A consistent methodology was applied to …

In Canada, the eastern tolerant hardwood forest is potentially at risk from air pollution.
Surveys indicate that, overall, the condition of hardwood forests has either not changed or …

Acid deposition over time scales of decades may deplete essential base cation (BC)
reserves in soils to the extent that forest health may be affected. In order to assess the …

Increased nitrate (NO3) concentrations in streamwaters draining forested catchments are
reportedly an early indicator of nitrogen (N) saturation. Nitrate concentrations in streams …

There is growing concern that available base cation pools in soil are declining in eastern
North America and that some forests are approaching nitrogen (N) saturation due to the …

The cycling of base cations (K, Ca, Mg, and Na) was investigated in a boreal balsam fir
forest (the Lake Laflamme Watershed) between 1999 and 2005. Base cation budgets were …

A sustainable forest management system requires that a balance must be reached between
ecosystem nutrient losses and gains in the course of a rotation. In order to determine the …

ABSTRACT The Athabasca Oil Sands Region of northern Alberta is home to the largest
source of S emissions in Canada, and some of the surrounding upland forests are located …

A dendrochemical survey of sugar maple (Acer saccharum Marsh) was conducted insouth-
central Ontario, which encompassed twenty-two sites in areas that both exceeded orwere …
