Fires are an important perturbation for the carbon (C) dynamics of boreal forests, especially when they stand-replacing. In North American crown fires predominant and, therefore, most studied. However, surface can also lead to major tree mortality with substantial implications C balance. Here, we assess short- (hours days) medium-term (1–3 years) effects different fire types (surface vs. crown) on postfire soil effluxes in jack pine (Pinus banksiana Lamb.) and black spruce (Picea mariana (Mill.) BSP) forest stands Northwest Territories, Canada. We found that while trees were instantly killed by four studied, died within 1 year after two three Associated this mortality, autotrophic respiration decreased both types, although at timings. The heterotrophic was either lower or unchanged measured 1–3 years type but increased immediately a fire, possibly due interaction between ash generation wetting performed suppress fire. Our results suggest thus substantially alter fluxes short medium term, through changes vegetation environment.
