Coastal wetlands of Lima are ecosystems where plants store a large amount of biomass, and soil with very rich with organic matter. These characteristics make these ecosystems potential and important carbon storage in the desert coast of Peru. Despite this, frequent fires of anthropogenic origin have been reported, which could affect this ecosystem service. The objective of this work was to quantify the carbon stored in the American bulrush (Schoenoplectus americanus) community in the Protected Area Los Pantanos de Villa Wildlige Refuge (RVSPV) under two scenarios of American Bulrush’s growth, the first scenario was a natural growth zone (unburned area), and the other was a post-fire zone (burned area) after a year of disturbance. For this, 5 plots of 1m2 were made in each scenario; in each plot the aboveground biomass (herbaceous and litter/necromass), the root biomass (roots and rhizomes) were measured, and soil samples were taken (up to 30 cm deep). The amount of carbon in the aboveground and belowground was measured by the Dumas method. Our results show that the total carbon sequestration values were 305.37 MgCha-1 in the unburned area, and 155.52 MgCha-1 in the burned area; in both scenarios, the soil stored the most significant amount in the first 10 cm. The potential of this coastal wetland to sequester carbon, and the possibility of including these ecosystems in financial incentives for climate change mitigation are discussed.
