Characteristics of sprouts occurrence by cutting to lower the stump height after harvesting the oak forest on the slope
This study was conducted to suggest an improved cutting to lower the stump height after harvesting that can induce the occurrence of high-quality root sprouts considering the locational characteristics of oak forests distributed mainly on slope. The study site was established in where the location environment and the stump diameter distribution were similar. The stumps were cut (control area) low horizontally based on the top of the slope, and cut (treatment area) parallel to the slope and close to the ground. The average number of occurred sprouts per stump was eleven, and there was no difference between control and treatment. The amount of stump lateral sprouts was decreased by 38% in the treatment (4.3 sprouts/stump) compared to the control (6.9 sprouts/stump). The occurrence of root sprouts (control: 3.8 sprouts/stump, treatment: 6.5 sprouts/stump) increased by 171%. 79.5% of the control lateral sprouts occurred in the lower slope direction where the stump height was relatively high. It was analyzed that lowing the overall stump height was a factor in reducing the occurrence of lateral sprouts. In order to promote the occurrence of high-quality root sprouts, an improved stump cutting, parallel to the slope and close to the ground, would be advantageous.
