Abstract
After clearcuting in bottomlands, oak seedlings that naturally regenerate are often overtopped by woody pioneer species, sprouts and herbaceous material. To improve the competitive status of three- to four-year-old oak seedlings in two bottomland stands in South Carolina, several herbicides and methods of application were used to kill and/or stunt the overtopping competition. Oak seedling diameter growth two years after treatment was nearly doubled by four of the late summer herbicide oversprays and by two of the directed applications. Height growth two years after treatment was increased by 1.9 to 2.7 feet by two of the oversprays and by one of the directed soil applications. Timing the oversprays so that competing vegetation shielded the oak seedlings from herbicide damage appeared to aid in improving the oak seedling's competitive position in the rapidly developing dominant canopy.
