Climate change as a driver of carbon flow in peatlands
Current climatic predictions for Scotland are for drier summers and winters in the East, and wetter winters in the West of the country. We are therefore investigating the impact of drought on carbon cycling in peatlands. Our main current site is located at Leys Estate, Banchory, where we are carrying out replicated drought experiments using rain-excluding shelters. Previous work was carried out as part of a PhD studentship by Hannah Toberman with CEH Bangor and the University of Bangor on a drought experiment at Plynlymon, Wales (CLIMOOR).
