In July 2016, a fire burnt six hectares of pine-sphagnum ecosystem in the Burns Bog Ecological Conservancy Area. Prolific seedling germination following the fire has drastically altered the post-fire ecosystem. In June 2023, an eddy covariance tower was installed in the burn zone to measure fluxes of carbon dioxide (CO2) and water vapor above a dense stand of 2 m [95% CI +/- 15] tall Lodgepole Pine saplings. By March, 2024 the mean sapling height in the study area 2.5 m [95% CI +/- 25]. Despite the rapid tree growth, ecosystem respiration exceeded gross primary production and gap-filled CO2 fluxes suggest the site was a net source of 1.27 g m-2 d-1 [95% CI +/- 0.59] over the study period. Maximum daily CO2 emissions were observed to coincide with maximum water table depth (0.77 m) in early October. Drawdown of the water table by the seedlings exposes the thick organic layer (>1m) to aerobic conditions which result in net Carbon loss from the ecosystem. Observations are ongoing and an annual budget will be estimated as more data becomes available.
