Abstract

Upland heath is an extensive habitat in the UK and is currently managed for a range of objectives: agricultural grazing, sporting interests, and biodiversity conservation. Increasingly land management will also have to address the provision of the ecosystem service of carbon sequestration (transfer of CO2 from the atmosphere into long-lived pools for storage). This study investigates carbon sequestration in Calluna- and Nardus-dominated upland heath vegetation communities in NE Scotland, which typically occurs as a result of low and high intensity management (grazing and burning) regimes, respectively. A 13CO2 tracer experiment compared the rate of carbon assimilation and the retention of assimilated carbon over six weeks during the growing season between these two communities. There was no difference in 13CO2 uptake between Calluna- or Nardus-dominated vegetation communities and they both retained over 40% of the assimilated 13C after six weeks. The 13C retained was mostly held in Calluna leaf and stem tissue in the Calluna-dominated community and in graminoid leaves in the Nardus-dominated community. Consideration of the strategies of the dominant species and the attributes of the tissues in which 13C was retained suggests that Calluna-dominated vegetation may be of greater benefit to carbon sequestration in the longer term.
