    Description

    Oak stump sprouts are vital to sustaining oak's presence and long-term dominance when regenerating oak-, mixed-hardwood forests. A study was initiated on the Hoosier National Forest in southern Indiana in 1987 to predict the sprouting potential and dominance probability of oaks. Before clearcutting, we sampled 2,188 trees of 5 oak species: white oak (Quercus alba L.), chestnut oak (Q. prinus L.), black oak (Q. velutina Lam.), scarlet oak (Q. coccinea Muenchh.), and northern red oak (Q. rubra L.). Measurements were taken during 15 years to develop sprouting and dominance probability models. A dominant oak was one that had 1 or more sprouts per stump in the dominant or codominant crown class 15 years after clearcutting. We used logistic regression to develop models for estimating dominance probabilities of the five species. Two models were developed that predict future sprout dominance based on a preharvest stand inventory, and six models were developed based on postharvest measurements of stump sprouts and competing vegetation.
