The North American Sugar Maple Project (NAMP) is a joint project of the Canadian Forest Service, Natural Resources Canada, and the United States Department of Agriculture Forest Service, initiated in 1988 with the goal of monitoring changes in crown condition of sugar maple (Acer saccharum Marsh.). The project includes 233 sites throughout the range of sugar maple in eastern North America. This report describes the condition of sugar maple for the 62 sites in Canada from 1988 to 1993; half of the trees were in sugar bushes (stands managed for sap production) and half in stands not managed as sugar bushes.
