Purpose: The capability of peatland ecosystems to regulate evapotranspiration (ET) following wildfire is a key control on the resilience of their globally important carbon stocks under future climatic conditions. Evaporation dominates post-fire ET, with canopy and sub-canopy removal restricting transpiration and increasing evaporation potential. Therefore, in order to project the hydrology and associated stability of peatlands to a diverse range of post-fire weather conditions and future climates the regulation of evaporation must be accurately parameterised in peatland ecohydrological models.
Abstract: To achieve this, we measure the surface resistance (rs) to evaporation over the growing season one year post-fire within four zones of a boreal peatland that burned to differing depths, relating rs to near surface soil tensions.
