Abstract

Forest insects and pathogens are major disturbance agents that have affected millions of
hectares in North America in recent decades, implying significant impacts to the carbon (C)
cycle. Here we review and synthesize published studies of the effects of biotic disturbances on
forest C cycling in the United States and Canada. Primary productivity in stands was reduced,
sometimes considerably, immediately following insect or pathogen attack. After repeated
growth reductions caused by some insects or pathogens or a single infestation by some bark
beetle species, tree mortality occurred, altering productivity and decomposition. In the years
following disturbance, primary productivity in some cases increased rapidly as a result of
enhanced growth by surviving vegetation, and in other cases increased slowly because of lower
