The CO2 dynamics and hydrology of an experimental Sphagnum farming site
(University of Waterloo, 2017-01-23)Sphagnum farming (or cultivation) is a recent land management strategy in reclaimed peatlands. The goal of Sphagnum farming is to cultivate Sphagnum fibers on a cyclic basis. Sphagnum moss is non-vascular and requires high ... -
Deeper Burning Increases Available Phosphorus, Promotes Moss Growth, and Carbon Dioxide Uptake in a Fen Peatland One-Year Post-Wildfire in Fort McMurray, AB
(University of Waterloo, 2019-01-25)Carbon storage in northern peatlands is estimated to be ~795 Tg, equivalent to ~40% of atmospheric CO2. Peatlands are dominant features of the Western Boreal Plains (WBP), which are experiencing a regime shift to a ... -
Effect of water table drawdown on northern peatland methane dynamics: Implications for climate change
(Wiley, 2004-10-07)As natural sources of methane (CH4), peatlands play an important role in the global carbon cycle. Climate models predict that evapotranspiration will increase under a 2 x CO2 scenario due to increased temperatures leading ... -
Evaluating parameter fitting and model design for unsaturated processes in peatlands
(University of Waterloo, 2019-04-08)Growing Sphagnum moss for peatland restoration and fibre farming requires the proper moisture regime be maintained; thus, there is a desire to optimize growth by creating ideal hydrological conditions. Sphagnum mosses have ... -
An evaluation of the water balance and moisture dynamics within Sphagnum mosses following the restoration (rewetting) of an abandoned block-cut bog
(University of Waterloo, 2011-09-30)Artificial drainage networks established throughout peatlands during the peat extraction process often remain active following abandonment, maintaining a water table relatively far from the surface of the peat and hindering ... -
The feasibility of field based mechanical compression to reduce the capillary barrier effect and increase CO2 sequestration in a restored cutover peatland
(University of Waterloo, 2019-01-28)Ten years after restoration was implemented at the Bois-des-Bel peatland (BdB) in Quebec, there was limited hydrological connectivity between the regenerated Sphagnum moss and the remnant cutover peat due to the formation ... -
Impacts Of Seismic Line Restoration Techniques On Nutrient Biogeochemical Processes In A Boreal Fen
(University of Waterloo, 2021-12-23)Peatlands contain 40 cm or more of partially-decomposed plant matter and sequester carbon and nutrients. The disturbance of peatlands alters these ecological functions. Seismic lines, long cutlines in the forest created ... -
Local controls on tree seedling growth following mounding on peatland seismic lines in Brazeau County and Lac La Biche, Alberta
(University of Waterloo, 2023-06-22)Seismic lines in boreal peatlands are struggling to restore native canopy level vegetation. Mounding is a common restoration method that provides an advantageous growing environment for native tree seedlings. Although many ... -
Methane Dynamics in a Southern Ontario Calcareous Fen
(University of Waterloo, 2020-08-07)Peatlands are important ecosystems that are pivotal for the global carbon budget. They have the ability to take carbon dioxide out of the atmosphere and store it within peat, which has very slow decomposition rates. Peatlands ... -
Microclimatic Effects of Forest to Peatland Transitions Within the Boreal Plains
(University of Waterloo, 2019-04-30)Peatlands cover approximately 50% of the total landscape of the Western Boreal Forest, which includes the sub-humid Boreal Plains (BP) ecozone. The BP experiences persistent water deficit conditions, promoting anaerobic ... -
The Role of Ericaceous Shrubs in the Surface Water Balance and Soil Water Availability of Cutover Peatland, Québec
(University of Waterloo, 2008-09-12)Peatlands are carbon sinks and occupy approximately 13% of Canada’s terrestrial surface of which 0.02% have been harvested for horticultural peat. The extraction of peat from natural peatlands alters the hydrology which ... -
The Surface and Subsurface Distribution and Transport of Sodium within a Constructed Fen Peatland in a Post-mined Landscape in the Alberta Oil Sands Region
(University of Waterloo, 2021-05-27)Nikanotee Fen Watershed is an engineered upland-fen peatland system in the Athabasca Oil Sands Region constructed from salvaged peat and forest soils, overburden and tailings sand materials. Sodium-rich leachate from ... -
Vadose zone flow patterns and their implications for sodium transport and aquifer recharge in a reclaimed fen watershed in the Athabasca Oil Sands Region, Alberta, Canada
(University of Waterloo, 2021-06-02)The reclaimed Nikanotee Fen watershed consists of an upland tailings sand aquifer, capped with a finer soil cover (LFH-mineral mix, or LFH) to support vegetation, that supplies groundwater to a low-lying fen peatland. ...
