Native vegetation removal affects the ecosystem ecological functions like nutrient cycling. Riparian forests act as a link between the terrestrial and aquatic environment, and thus have an important role in the biogeochemical cycling operation. Litter-soil layer is mainly responsible for nutrient cycling and went back into the system through the decomposition, which is the mineralization of organic matter with the breakdown of organic compounds in inorganic. This process is carried out by microorganisms, being dependent on the chemical composition of the vegetable substrate, the environmental temperature and humidity conditions, and soil conditions, including aggregation and density. Thus, it can be used as the recovery parameters of an ecosystem production and decomposition of litter, its chemical composition and return nutrients to the system; the chemical and physical characteristics of the soil as carbon stocks, as well as their microbial activity. This project aims to assess the nutrient cycling in riparian forests reforestation areas as ecological succession endpoint in watersheds with reforested streams stretches in the city of São Carlos region. For this, we selected nine areas between reforested and control, for monitoring the deposition, decomposition and chemical composition of litter, and also evaluated and characterized the soil properties in these areas. The results will allow a better understanding of the effects of restoration and riparian vegetation structure in the production and decomposition of litter and so the maintenance of biogeochemical cycles. Thus, you can specify parameters for the implementation of future projects and for better management of recovery areas.
