Temporal replicate data of measurements published in Dezzeo et al. (2021) Fine root carbon stocks and dynamics along a degradation gradient of palm swamp forest in a Peruvian Amazon peatland. Submitted to Ecosystems for review. Data collected in Iquitos, Peru, to evaluate fine root C stocks and dynamics as influenced by peat forest degradation and environmental controls along a palm swamp peatland degradation gradient (Intact site, moderately degraded site and heavily degraded site) considering structural changes in vegetation.
