Short summary
We developed century-scale records of wood nitrogen isotopes (δ15N) from 16 trees across a long-term savanna fire experiment. Results show similar long-term trajectories in three out of four burn treatments. Lack of evidence to support our hypotheses underscores the complexity of nitrogen dynamics inferred from wood δ15N. This is the first study to our knowledge to investigate multi-decadal effects of fire at different return intervals on wood δ15N, a potential proxy of nitrogen availability.
