Cut stumps can be temporary hot spots of carbon emissions due to connections to decaying root systems. Drivers of variation in stump decomposition have yet to be clearly identified, including interactions with stump sprouting, an important regeneration pathway after harvest in temperate deciduous forests. The aim of this study was to identify the effects of sprouting relative to other abiotic and biotic factors on carbon emissions from cut stumps.

One physiological mechanism favoring Quercus over mesophytic and/or shade-tolerant deciduous broadleaved species is prolific and vigorous resprouting following topkill. Generalizations regarding interspecific differences in fire-induced resprouting are confounded by interactions between biotic and abiotic factors.
