Approximately 1.19 x 106 km2 of Canada is covered by peatlands containing over 110 to 150 Gt C. Most are relatively pristine. A tiny area (~ 0.21 x 106 ha) of Canadian peatlands is affected by land-use change. The most common land disturbances are due to agriculture, fossil fuel and mineral exploration and extraction, and the creation of hydroelectric reservoirs. A small area of peatlands (~350 km2) is disturbed by peat extraction for use in horticulture. As part of attempting to quantify CO2 emissions from peatlands, we have adapted the Coupmodel to simulate a restored bog. Coupmodel reproduces the exchanges of energy, water, and carbon well. The key, it appears, to the simulation's success is being able to approximate the seasonal distribution of the water table depth. Our simulations are compared to the measurement reported in Nugent et al. (2018). The simulated bog returns to a sink in the same range of undisturbed peatlands a decade or so after restoration. The sink strength is a function of water table depth. Simulations also show that the restored peatlands are relatively insensitive to climate change over the projected conditions for the next one hundred years.
