In my PhD-project I study availability of groundwater and how it affects soil organic carbon, nutrient accumulation and tree growth.

By using a high density tree and soil survey in relation to high resolution hydrological maps, I try to understand the spatial variation of soil properties and forest growth. All my reseach is conducted within the Krycklan Catchment. 

Further understanding of how hydrology controls the spatial variation of soil properties and forest growth can be used to locate areas of with high potential of forest growth and carbon sequestration. My reseach also tries to further the understanding of  the commonly observed production gradients along slopes in Boreal landscapes, moving from recharge to discharge areas.
