This study examines changes in peat bogs resulting from peat extraction and grazing. The study also found that a far more significant impact to these land forms in the long term, with far greater and more rapid change has occurred as a result of windfarm construction. The authors write that "Although the installation of individual turbines over blanket bog often results in the extraction of peat in isolated locations, the associated infrastructure of tracks and electrical cable conduits has wider impact not only on the hydrology, but also on peatland geomorphology." According to the report "Windfarm installations have already significantly altered the functioning of some of these ecosystems, and without urgent protection some of the blanket bogs identified here may soon be lost. Action of a most urgent nature is needed from the governments of Cantabria and Castilla y León in order to retain what remains and restore these systems to important natural carbon sinks."
