To determine if repeated summer browsing caus a C (source) limitation in trees in the long-term, we analyd the non-structural carbohydrate (NSC) and nitrogen (N) concentrations and pools of Betula pubescens saplings subjected to different cl
ipping treatments (unclipped, 33% and 66% shoot removal) for 7 years. 2. The short-term effect of browsing on C allocation was assd by clipping trees with different browsing histories and analyzing their C and N respons within the same growing ason. 3. Long-term repetitive summer browsing significantly decread sapling growth and soluble sugar (SS) concentrations in fine roots. However, trees
