In order to determine the dynamics of biomass, carbon and CO2e, a study was carried out in the high dry varillal forest of Iquitos, Peru under the principle of continuous forest inventory, during the period 2005 to 2017, using three permanent plots of one hectare each divided into 100 sub-plots of 10 x 10 m. The average at the end of the census period (2017), for aboveground biomass was 186.18±5.87 t/ha, for aboveground carbon it was 87.03±76 t/ha; for the carbon dioxide equivalent of trees above ground it was 320.85±10.12 tCO2e/ha and below ground it was 118.71±3.75 tCO2e/ha. The aboveground biomass in trees without lianas was 121.53±56,315 t/ha, and in trees with lianas that restrict their growth was 2.81 ± 5.14 t/ha. While the aboveground biomass of trees with regular crown was 99.57±62.88 t/ha, in those with irregular crown 36.09±40.39 t/ha. The annual growth rate of the aver...
