Abstract

Understory pine and hardwood regeneration in the Ozark and Ouachita National Forests were measured in 1995 for the first time following thinning and hardwood control at plot establishment 1985-87. Red maple (Acer rubrum), shortleaf pine and flowering dogwood (Cornus florida) were the most frequently recorded species. Understory shortleaf pine stems have declined consistently since 1995. The binomial logistic regression model showed that site index and overstory shortleaf pine basal area were negatively related to shortleaf pine regeneration (P<0.05). Overstory shortleaf pine thinning may initiate shortleaf pine regeneration at early stage; however, newly regenerated hardwood species will dominate the entire regeneration process long-term, if hardwood control treatments are not applied.
