Abstract
Abstract Stump sprouts are an important component of the regeneration for northern pin oak on scrub oak sites in Central Wisconsin, but there exists little quantitative information about their actual contribution. This study examines the occurrence of sprouting from northern pin oak stumps remaining after overstory removal in four stands in Central Wisconsin. On average, 85% of all stumps sprouted. Sprouting frequency diminished significantly (P < 0.0001) as stump diameter increased, but even the largest stumps sprouted at rates of 71% or better. With stump sprouting rates this high, coppice regeneration could fill much of the regeneration need for similar scrub oak sites.
