Theme X. Peatland carbon budgets and greenhouse gas (GHG) fluxes
In this paper we present data from Black Law Wind Farm, Scotland, to examine the effect of wind turbines on (1) peatland surface and subsurface temperatures, soil moisture and water table depth and (2) greenhouse gas fluxes and pore water dissolved organic carbon concentrations. Moreover, within our experimental framework we examine the impact of the three main plant functional types (shrubs, mosses and sedges) and their interaction with wind turbine affect to allow both upscaling and the implications of changes in plant composition, over the long-term, on carbon fluxes to be elucidated. The results indicate that there are relationships between wind turbines, plant functional type and their interactions and carbon fluxes. Consequently, the long-term effects of wind farms on carbon cycling needs to be taken into account when considering their life cycle carbon budget.
