Project Summary

My research aims to quantify CO2 fluxes from damaged peatlands in the southwest of England (Exmoor and Dartmoor); to understand the biotic and abiotic controls (both temporal and spatial) driving CO2 fluxes and how eco-hydrological restoration of these peatlands affects both the magnitude and direction of fluxes and their relationships with controlling variables.  In order to do this I collect plot scale measurements of net ecosystem exchange, partitioned below-ground respiration (total, heterotrophic and autotrophic) and a range of potential biotic and abiotic controls.  I use proximal (digital cameras and time-lapse cameras), distal (Unmanned Aerial Vehicle mounted cameras) and satellite (MODIS) remotely sensed data to investigate links between vegetation phenology, structure and distribution and CO2 fluxes at a range of spatial extents.
