Maple tapping guidelines, which specify the number of taps in relation to bole diameter, and the spacing and depth of tapholes, have been devised primarily using sugar maple wounding as a model. With its importance as a present and future resource for maple sap, it is critical that we extend our knowledge about taphole wounds to red maple so that, if necessary, these guidelines can be revised to include the proper and sustainable tapping of this species.

Sugarmakers should consider tapping red maples to supplement sap production from sugar maples.
While sugar maples are the gold standard for sap production, red maples are also an important source of sap for maple products.
