Defoliation-induced changes in foliage quality during a spruce budworm outbreak

This dataset is associated with the article authored by Louis De Grandpré et al. titled "Defoliation-induced changes in foliage quality may trigger broad-scale insect outbreaks" accepted for publication in Communications Biology. In this study, progression of a spruce budworm outbreak over several years was shown to be associated with increased soil nutrient fluxes and availability and improved foliage quality in surviving host trees.
