DescriptionInsect herbivory that results in extensive defoliation has the potential to affect forest nitrogen dynamics. High-nitrogen leaf materials and insect excrement (frass) are deposited on the forest floor during the growing season, potentially providing a pulse of labile carbon and nitrogen. Whether the released nitrogen is retained by or lost from the forest system has important implications for nitrogen dynamics within the forest, as well as across the larger landscape. Invasion of forests in the New Jersey Pine Barrens by the gypsy moth (Lymantria dispar L.) during the summer months of 2006 and 2007 provided the opportunity to study the impact of defoliation on nitrogen cycling in an oak-pine stand. Nitrogen budgets were produced for a non-defoliated year, 2005, and a year in which forest plots were completely defoliated, 2007, in order to assess the ecosystemlevel effects of defoliation. The two budgets were not as distinct as expected. This was due, in part, to the lack of adequate forest floor data for 2005. It is likely that the forest floor is the site of altered nitrogen cycling and that microbial activity is a key component of nitrogen retention and/or loss. Future studies should focus on filling the gaps in our understanding of the Pine Barrens nitrogen budget.
