Many pests and other stresses affect maple trees growing in a sugarbush. Some pests can markedly reduce sap quantity and quality; others, although conspicuous, are not important. Stresses can result from activities by people and from natural phenomena. Recognizing problems and understanding the factors that contribute to their occurrence, development, and significance are necessary to maintain tree health. This report brings together current information on the living agents and nonliving factors that can cause problems in sugarbushes. Insects, diseases, improper forest stand management, and unwise sugaring practices are illustrated and ways to prevent or reduce their effects are described.
