Interactive comment on “Modelling contrasting responses of wetland productivity to changes in water table depth” by R. F. Grant et al

Responses of wetland carbon cycling to environmental changes, particularly changes in water table depth, which are the key determinants to control the ecological and biogeochemical functions of wetlands, are highly non-linear and complex due to the dynamic interactions of several physical and biological processes. Several field experiments have found that wetland productivities have a significantly different response to changes in water table depth with respect to the position of water table at which the change occurred. Therefore, it is critical for an ecosystem model to capture this phenomenon in order to project well how the wetland carbon cycling would respond to the projected climate change. The authors presented the abilities of an ecosystem model ecosys to capture the contrasting responses of CO2 fluxes at Lost Creek, WI, to changes in temperature and water table depth. This model was evaluated by comparing the modelled carbon fluxes with the EC measured C fluxes with a detailed C2736
