Peatland Nitrogen Pollution Experiment (Whim Bog)

The purpose of the Whim Bog field manipulation experiment is to study the effects of nitrogen air pollution on a semi-natural peatland ecosystem. Peatlands occupy 12% of the UK’s land area and capture/store vast quantities of carbon dioxide (CO2) from the atmosphere, helping to offset human-generated greenhouse gas emissions that drive climate change. The Whim Bog experiment releases nitrogen onto the site in controlled volumes to mimic the effects of different levels of airborne nitrogen pollution. Researchers study the effects of different levels and combinations of elevated nitrogen on the peatland bog vegetation and on ecosystem services such as carbon storage and greenhouse gas emissions.
