Silvicultural Management of Beech and the Beech Bark Disease
Herbicides were used to control dense, advance reproduction of American beech and sprouting from roots and stumps of harvested beech in a northern hardwood stand in eastern Maine. Beech comprised 51% of the overstory basal area and was highly defective as a result of the beech bark disease. Beech saplings accounted for 80% of the advance reproduction. The herbicides glyphosate (Roundup®) or triclopyr (Garlon 3A®), applied using a backpack mist blower, were effective in reducing advance reproduction of beech by 100% and 93%, respectively. When applied in frills on larger beech six weeks prior to harvesting, glyphosate reduced the number of sprouts, two growing seasons after treatment, by 85%; triclopyr by 87%. Beech individuals believed to be resistant to infestation by the beech scale were left as a component of the residual overstory, along with sugar maple, red maple, yellow birch, and paper birch. The two-stage application of herbicides followed by shelter-wood harvesting is a strategy for managing stands dominated by defective beech. North. J. Appl. For. 3:89-91, Sept. 1986.
