Two-decadal trends in aboveground litterfall and net primary production in self-thinning Pinus banksiana stands in Wood Buffalo National Park, NWT, Canada

A two-decade study in Wood Buffalo National Park, Canada, revealed that aboveground net primary production (ANPP) in self-thinning jack pine stands peaks at around 500 grams per square meter annually in stands aged 30–50 years. The research found a declining trend in ANPP after 50 years, with older stands exhibiting lower biomass turnover rates compared to younger ones. The study employed long-term litterfall collection and biomass estimation using allometric relationships, providing insights into the carbon dynamics of jack pine stands at different stages of self-thinning.
