Abstract

A Midstory competition control and shoot clipping have been proposed to increase the vigor and height of advance bottomland oak reproduction. Results from a study in east-central Mississippi showed that advance cherrybark oak (Quercus pagoda Raf) released from midstory competition had greater survival than nonreleased seedlings, 64% and 48%, respectively, 9 yr after treatment. Released seedlings were also 2.5-3.4 ft taller than nonreleased seedlings depending on site. However, this significant growth response was not observed until 3 to 5 yr after release. Clipping oak seedlings at the time of release did not result in greater seedling heights after 9 yr, but subsequent sprouts were similar in height to unclipped seedlings. Midstory competition control is recommended to increased the vigor and height of advance bottomland oak reproduction. This practice may need to be conducted 5 to 10 yr prior to final overstory removal to maximize height growth of advance reproduction.
