Dynamics of elemental composition in the sediments of Can Gio mangrove Biosphere reserve period of 13 years after Durian typhoon 2006

Abstract

Corg levels, Ntot level, and CN ratio are indicators for nitrogen limitation of plants and other organisms in the recovery process of storm-damaged forests. Here we compare between the 2 sections by multifactor-ANOVA analysis sediment characteristics along with the succession of a monoculture of Rhizophora in the South Vietnam with data from from 2007 to 2019 to know the initial state of the sediment after the disturbance and change during the self-recovery of the ecosystem. In the first stage, the Corg levels were much higher, while the Ntot deficiency was a crisis. Due to the presence of tall trees and the recovery process, the growth of nitrogen fixation mediated by attached microalgae on the surface sediments and the microbes living in the rhizosphere. Follow-up assessments and field experiments are needed to understand the sediment characteristics vary during the self-recovery of the ecosystem.
