Duration: 2010-2014   Keywords: ash-fertilization, biodiversity, cut-away peatland, greenhouse gases, mire, peat, restoration
Research Programme: Forests for multiple purposes

Objectives

The project
1) investigates the impacts of restoration on the structure and function of peatland ecosystems,
2) analyses the cost-efficiency of restoration, and
3) provides information for the rehabilitation of cut-over peatlands.

The aims are to provide information on the ecological and economical sustainability of restoration for planning and decision processes.

The first subproject investigates the impacts of different restoration methods on the ground water table, nutrient economy, vegetation composition, tree stand structure, and decomposition rates of litter and peat of peatlands. The flow of greenhouse gases as a response to increased temperature and restoration is measured in order to investigate the combined influence of climate change and change of water level on the emission of greenhouse gases.

The second subproject analyses the process, which develops and measures the cost-efficiency and quality of restoration (Balanced Scorecard (BSC) measures) and investigates how the system works in practice. The major focus is to investigate how documented scientific knowledge and tacit knowledge are identified and applied during the process.

The third subproject focuses on the effects of rehabilitation methods and peat- and wood-ash fertilizers to the vegetation and early establishment of tree seedlings on cut-away peatlands.

The project is closely conntected to the peatland project of Northern Ostrobothnia and Kainuu, in which ecosystem services of peatlands (biodiversity, greenhouse gases, recreation, reindeer husbandry, economical impacts) and alternative rehabilitation measures of cut-over peatlands are investigated.
