Post-fire soil respiration in relation to burnt wood management in a Mediterranean mountain ecosystem

摘要: After a wildfire, the management of burnt wood may determine microclimatic conditions and microbiological activity with potential to affect soil respiration. To experimentally analyze effect on respiration, we manipulated recently burned pine forest in Mediterranean mountain (Sierra Nevada National Natural Park, SE Spain). Three representative treatments post-fire were established at two elevations: (1) “salvage logging” (SL), where all trees cut, trunks removed, branches chipped; (2) “non-intervention” (NI), leaving standing; (3) “cut plus lopping” (CL), treatment felled, main lopped off, but left situ partially covering ground surface. Seasonal measurements carried out over course years. In addition, performed continuous diurnal campaigns an irrigation experiment ascertain roles temperature moisture determining CO2 fluxes across treatments. Soil highest CL (average 3.34 ± 0.19mol m −2 s −1 ) lowest
