Restoration ecology

Ecological restoration assists damaged or destroyed ecosystems to recover. Restoration ecology is the science studying this recovery process

The research is focused on ecological and physical processes in terrestrial and aquatic ecosystems. Of particular interest are the interactions between different parts of the landscape, for example between land and water and between different parts of a water system. Important questions are (1) whether restoration projects reach their goals which often deal with the recreation of a lost stage, (2) to what extent restoration projects can maximize certain ecosystem components to increase the amount of a specific ecosystem service, (3) how restoration projects can be designed with respect to future climate changes, and (4) how various human actors affect different parts of a restoration project. The research is carried out in collaboration with researchers at several Swedish and foreign universities and comprises, besides ecology, also disciplines such as political science and environmental history.
