Bruno Périchon,Patrice Courvalins that are important in understanding forest function and the consequences of atmospheric deposition to forested ecosystems. Chapter 1 described the silvical characteristics of the spruce-fir forest; further information can be obtained on the forest types included in the spruce-fir category from Eyre (1980) and USDA (1965).

The roles of many of these natural and airborne chemical stress agents in the decline of red spruce were unknown at the onset of the North American Forest Response Program in 1985.
