Abstract

Decline of sugar maple (Acer saccharum Marsh.) has been a problem on the Allegheny Plateau of Pennsylvania since the mid-1980's (Kolb and McCormick 1993; Williams et al. 1996). Horsley et al. (this volume) found that declining stands were distinguished from non-declining stands by a combination of repeated insect defoliation and low foliar calcium and magnesium concentrations. Stands that exhibited only one of these two conditions remained healthy. Information is needed (1) to determine whether low foliar nutrient concentrations are related to soil quality, (2) to determine key parameters and threshold values that describe soil conditions which might predispose a stand to decline, and (3) to develop methods to predict the distribution of susceptible sites across the landscape. Furthermore, information about the role of acid deposition in inducing soil fertility problems remains elusive.
