Larch forests (Larix spp.) cover approximately 2.6 million km² across Siberia, yet little is known about the magnitude and drivers of carbon combustion in these ecosystems. To address the paucity of field-based estimates of fuel load and consumption in Siberian larch forests, we sampled 41 burned plots, one to two years after fire, in Cajander larch (Larix cajanderi) forests in the Republic of Sakha (Yakutia), Russia. We estimated pre-fire carbon stocks and combustion with the objective of identifying the main drivers of carbon emissions.
