Decline in Net Ecosystem Productivity Following Canopy Transition to Late-Succession Forests

Popis výsledku v původním jazyce

Boreal forests are critical to the global carbon (C) cycle. Despite recent advances in our understanding of boreal C budgets, C dynamics during compositional transition to late-succession forests remain unclear. Using a carefully replicated 203-year chronosequence, we examined long-term patterns of forest C stocks and net ecosystem productivity (NEP) following stand-replacing fire in the boreal forest of centralCanada.Wemeasured all C pools, including understorey vegetation, belowground biomass, and soil C, which are often missing from C budgets.Wefound a slight decrease in total ecosystem Cstocks during early stand initiation, between 1 and 8 years after fire, at -0.90 Mg C ha-1 y-1. As stands regenerated, live vegetation biomass increased rapidly, with total ecosystem C stocks reaching a maximum of 287.72 Mg C ha-1 92 years after fire. Total ecosystem C mass then decreased in the 140- and 203- year-old stands, losing between -0.50 and -0.74 Mg C ha-1 y-1, contrasting with views that
