Abstract

Coppice regeneration is favored in North America for oak (Quercus spp.) regeneration. Although models of oak stump sprouting do not consider Armillaria root disease, many oak stumps in upland Ozark forest stands carry active Armillaria root crown infections. The spatial pattern of sprouting on oak stumps is related to the circumferential distribution of Armillaria-infected roots. We draw attention to the proper interpretation of sprout "tree" age, re: root system age and the ages of Armillaria infections present. The pattern of channels left by decay of stump root systems seems well-suited to attracting roots into contact with Armillaria inocula.
