Oak Stump Sprouting on Dry Sites in Northern Lower Michigan
Abstract:In clearcut portions of 37 stands, stumps from northern red, northern pin, and white oak trees, averaging about 65 years old when felled, were measured to relate sprouting to stump diameter, estimated dbh, slope position, aspect, site index, and parent tree (stump) age. At least one vigorous sprout was produced by 80 and 77% of northern red and northern pin oak stumps, respectively, and sprouting was independent of stump diameter. In contrast, 54% of white oak stumps produced at least one vigorous sprout, and sprouting was related to stump diameter. Northern red and northern pin oaks sprouted least frequently on lower slopes, whereas white oaks sprouted least frequently on midslope positions. White oak sprouting was also less frequent on south-and west-facing slopes. Sprouting of white and northern pin oaks was weakly associated with site index. The sprouting of all species was related to tree age, but only white oak showed a consistent trend of decreased sprouting with increased tree age. An average of 134 oak stumps per acre produced at least one vigorous sprout. North. J. Appl. For. 4:142-145, Sept. 1987.
