Carbon gas exchange, primary production and litter decomposition of a restored fen on a former oil well-pad
(University of Waterloo, 2018-02-16)Over 500,000 oil and gas wells have been drilled in Alberta. Recently updated peatland restoration criteria for well-pads creates incentive for peatland restoration, but little is known about functional outcomes of restoration ... -
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 ... -
The combined impact of salinity and water table on Juncus balticus growth: Implications for fen construction in the Athabasca Oil Sands Region
(University of Waterloo, 2022-08-05)Oil sands mining destroys peatlands by removing all vegetation on the ground and digging up to 75 m deep to reach the oil. To investigate methods to return peatlands to the post-mining landscape, a fen reclamation project ... -
Dissolved organic carbon production and transport in a constructed watershed in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2018-01-23)Within the Western Boreal Plains, a significant amount of surface cover has been removed through open-pit oil sands mining activities, which includes fen peatlands. Fen construction has been performed on the post-oil sands ... -
Effects of restoring peatland seismic lines on soil properties in boreal Alberta, Canada
(University of Waterloo, 2021-10-04)Long, linear disturbances called seismic lines have been and continue to be created through the boreal forest in Alberta for petroleum exploration. Restoration of these seismic lines has shown some success but is often ... -
Impacts of resource access road crossings on ecohydrology and carbon dynamics of boreal peatlands
(University of Waterloo, 2019-09-04)Resource access road crossings are expected to alter peatland ecohydrological properties by obstructing surface and sub-surface water flows, providing favorable conditions to stimulate microbial activity, and ultimately ... -
Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
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 ... -
Influence of graminoid species identity on carbon exchange in a restored peatland in central Alberta, Canada
(University of Waterloo, 2017-09-27)Peatlands are globally important ecosystems for carbon sequestration. Commercial extraction of peat layers alters the ecosystem services provided by pristine peatlands. One metric of peatland restoration is recovery of ... -
Methane cycling in horticultural extracted, restored, and unrestored peatlands in central Alberta, Canada
(University of Waterloo, 2020-01-24)Horticulture peat extraction drastically changes peatland ecosystems and their carbon and greenhouse gas balance. Comprehensive study on the combined response of methane (CH4) cycling (i.e., CH4 production, oxidation, ... -
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 ... -
Methane dynamics of a constructed fen in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2017-01-18)Oil sands mining activities in the Athabasca Oil Sands Region in northeastern Alberta, Canada have resulted in an extensive amount of land disturbance. The Alberta government requires some reclamation of disturbed land to ... -
Organic matter decomposition at a constructed fen in the Athabasca Oil Sands Region in Alberta, Canada
(University of Waterloo, 2019-03-13)Resource mining and extraction in northern Alberta has resulted in substantial disturbances across a variety of ecosystems, including fen peatlands. Provincial regulations require companies to reclaim disturbed areas to ... -
Salinity Effects on Dissolved Organic Carbon Concentration and Quality in a Constructed Fen Peatland, Fort McMurray, AB
(University of Waterloo, 2020-08-05)In northern Alberta, oil sands mining disturbs the landscape; reclamation to an “equivalent land capability” is required, and industry is testing peatland construction as part of landscape reclamation. To determine if these ...
