Tropical peat in the Peruvian Amazon have high palm densities of Mauritia flexuosa L.f. (aguaje), which are often cut instead of being raised to collect their fruits. This important type of forest alteration can generate changes in the dynamics of fine roots. The productivity, mortality, biomass, necromass and decomposition of fine roots were studied, as well as the cut-off rate of M. flexuosa along an alteration gradient that includes sites of low, moderate and high alteration. Root productivity at the plot level was higher for the site with low alteration than the moderate and high site. Likewise, a negative relationship was found between fine root mortality and precipitation. The fine-root carbon biomass was consistently higher than the fine-root carbon necromass between sites and between the ages of M. flexuosa within the sites. The percentage of carbon (C) of fine roots was higher for the moderate site in all species and ages of M. flexuosa compared to the high site. The C: N ratio of the fine roots showed low values in the high site than the low site for M. flexuosa seedling. However, for the same site, the C: N ratio of fine roots was higher in individuals with low M. flexuosa than dicot trees, respectively. Finally, the cut-off rate of M. flexuosa was 10 individuals ha-1 year-1, and the average cut-off number was 68 individuals ha-1.
