We assessed changes in SR rates during early (1.5–4 years) post-fire stages. Overall, both high burn-severity sites showed higher SR rates than the unburnt site. The low burn-severity and unburnt sites presented similar SR rates. Slope aspect clearly influenced post-fire SR rates at the high burn-severity sites. Decaying stump roots resulted in high contributions to the post-fire SR.
