Abstract: Though northern white-cedar is a common and economically important component of the Acadian Forest of Maine and adjacent Canada, there is little regional data about the growth and development of this species. Sixty sites in northern Maine were used to compare growth of cedar to that of red spruce and balsam fir along a range of site classes and light exposures. On average, cedar grew faster than spruce but slower than fir, however species-specific basal area growth rates were affected differently by site class and light exposure. Balsam fir was the only species showing strong growth responses to increased crown light levels. Decay was present in all species, but a higher proportion of cedar stems were decayed. The proportion of decayed balsam fir stems increased as site drainage improved. Our data suggest that cedar in Maine often exceed 150 years of readable rings at breast height.
