Abstract
Nuttall oaks from a dense seedling catch survived for 5 to 10 years in complete shade and for 15 years with 1 or 2 hours of daily sunlight. They made little growth, but they responded well when released after periods of 1 to 9 years. Time of release did not affect subsequent survival or growth. Green ash, water hickory, and sugarberry survived equally well and outgrew the oaks after the overstory was removed. After 15 years, the largest ashes were 5 to 10 feet taller and 1.5 to 2 times larger in diameter than most Nuttalls. On the better sites and where openings were one-fifth acre or larger, trees emerged from the vines in 5 to 10 years.
