Field measurements


The following measurements will be performed:
  1. Climate (AWS)
  2. C fluxes (photosynthesis & respiration)
  3. GHG emissions (CH4 and N2O)
  4. C stocks (peat depth; carbon densities; vegetation carbon)
  5. Vegetation dynamics (composition and change)
  6. Water balance (in versus out)
  7. Water quality (DOC & POC)
  8. Peat pipes (GPR surveys)
  9. Crane fly (emergence & abundance)
The following measurements will be performed across the monitoring areas:
  • At the start and end of the project, peat depth (mainly manual peat rod method) and the location and extent of any peat pipes found will be assessed using ground penetrating radar.
  • Vegetation composition and cover – to include both vascular plants and bryophytes using digital pictures and visual assessment on site (during summer).
  • Sward height and grazing intensity to be indicated using biomass utilisation, heather grazing index or similar techniques. Heather growth/vigour will be specifically recorded (e.g. height or shoot growth increment length; during summer).
  • Hourly water tables measured at permanent quadrats using automated loggers and manual water samples will be taken.
  • Hourly weather data: light, rainfall, humidity, pressure, air and soil temperature measured by a weather station (AWS) and used to inform models of photosynthesis and greenhouse gas fluxes.
  • Manual light and dark chamber measurements of carbon dioxide flux (photosynthesis and respiration) and manual methane flux measurements representing a range of water tables and vegetation covers (seasonally, throughout the year).
