In the context of climate change, Congo Basin forests play a major role in carbon regulation. However, dead wood remains poorly documented in peatland swamp forests. This study estimates dead-wood carbon stocks at Bodzale, in Likouala. Four 1-ha plots were established, including three in swamp forest and one in terra firme forest. Downed dead wood and standing dead wood were inventoried and then classified according to diameter and state of decomposition. In total, 795 dead-wood elements were recorded, comprising 750 logs and 45 snags. Carbon stocks in logs ranged from 0.062 to 0.194 tC ha-1, with the highest value in P1 and the lowest in P4. Stocks in snags were low, ranging from 0.0016 to 0.0025 tC ha-1. Stocks did not differ significantly among plots for logs (p = 0.085), but did differ according to decomposition class (p = 0.001). These findings highlight the value of integrating dead wood into carbon budgets for Congolese peatland forests.
