Predicting Sugar Maple Mortality in Managed Uneven-Aged Northern Hardwood Stands
Assessment of mortality among 1,455 shade-tolerant sugar maple (Acer saccharum Marsh.) trees from managed uneven-aged northern hardwood stands in two physiographic regions of New York State revealed that loss varied with tree diameter, residual stand basal area, and time since the last selection system cutting. Larger trees showed lower rates of mortality than smaller ones, and mortality increased with residual stand basal area and time since cutting. Coefficients for predictor equations are presented, along with a table of mortality estimates by tree diameter for stands of different levels of residual stocking and with different lapse times after selection system cutting.
