As implied by the names of these pests, most insect related problems in sugar maple involve the leaves. Other Problems Sugar maple is very sensitive to high sodium levels in the soil. Hence it can sustain major injury from salt added to road surfaces to melt winter ice and snow. The use of salt in the winter is a common practice throughout much of New York State and New England. Affected trees are found primarily along roads, although in extreme cases water drainage from roads into maple stands has caused extensive damage.
Salt enters the roots and accumulates throughout the tree.
When soil moisture levels decrease, the high salt concentration in the tissues causes the death of many twigs. Therefore, salt damage becomes obvious following long dry periods during the summer. The successful management of any forest must begin with specific goals. Stands of sugar maple can be managed to produce sap for syrup and wood for a variety of products. Both of these alternatives can be beneficial to wildlife by providing cover, browse, and nesting sites.
