Abstract
From 2000 to 2008 hardwood regeneration <5 cm diameter at breast height were individually tagged and monitored in the Boston Mountains of northern Arkansas. The study site is a 32-ha area in an upland oak-hickory stand that was approximately 70 years old in 2000. Mean basal area for all standing trees in 2000 was 25.9 m
2/ha, and there were 417 standing trees/ha. Stocking was 88 percent. In 2000 we established 480 permanent circular regeneration plots, each with a 1.31-m radius. In each quarter of each regeneration plot, we measured species, distance, azimuth, height, ground diameter, stem age, and origin of the two tallest trees of northern red oak (
Quercus rubra) and white oak (
Q. alba). By mid-2001 this stand began to exhibit symptoms of severe oak decline. In 2004, a prescribed fire was applied to one-fourth of the study area.
