Abstract

This study uses a series of gully sites across the Bleaklow plateau (Peak District, Derbyshire), subject to different restoration interventions, to investigate differences in carbon pathways (DOC, CO2) and hydrology between restoration strategies and gully position. The results show that the position within the gully (interfluve, gully side, or gully floor) does not significantly affect water quality but that it plays a significant role in CO2 exchange. Gully floors are areas of high photosynthesis and ecosystem respiration, though net ecosystem exchange is not significantly different across the gully. While gully position plays a role in the cycling of some carbon species, this study highlights the importance of vegetation as a key control on carbon cycling
