On a recent walk through the Arboretum's collection of tress and shrubs in our Certified Plant Professional area, some damage was noted on the pecan tree. These rows of holes are not caused by insects, but rather by the yellow-bellied sapsucker. This woodpecker does exactly what its name implies: feeds on the sap from trees. It also will eat or feed to its young any insects that are drawn to the sap. Will it harm the tree? What can be done to prevent it or discourage it? Click here for all the answers: SAPSUCKER DAMAGE
