Objectives

Clear-cut and soil amelioration cause nutrient release over time and space in the catchment. This study follows the dynamics of greenhouse gases in wetland buffer zones left between the and the water outlet of the catchment. Possible transformation of nitrogen into nitrous oxide and increase in anaerobic decomposition by means of methane exchange between soil and the atmosphere within the buffer zone is evaluated. The aim is to predict the extent and volume of greenhouse gas emissions in the wetland buffer, and find prerequisites for the buffer construction in order to reduce the greenhouse gas emissions caused by forestry.
