Since European settlement of the Canadian Prairies there has been substantial loss of wetlands. This loss occurs in large part due to drainage by private agricultural operators seeking to boost the productivity of their land. Policy makers now seek not only to conserve wetlands and prevent...
Extensive work, funded in part by the Cumulative Environmental Management Association, has been devoted to developing sophisticated tools for evaluating shallow open water reclaimed marshes on oil sands mined land. These tools use environmental and biological measurements to assess the condition...
Development of a GIS Water Table Visualization Tool (WTVT) for Determining Water Table Position in Heterogeneous Landscapes in the Boreal Plains Ecozone, AlbertaDownload
The Boreal Plain is currently undergoing an unprecedented rate of land use change from oil and gas extraction as well as forestry. This change needs to be managed responsibly to ensure the long term sustainability of the region, both ecologically and economically. As part of this understanding...
Diversity of wetland non-biting midges (Diptera: Chironomidae) and their responses to environmental factors in AlbertaDownload
Wetlands provide a wide range of services, including improving water quality, providing habitats for wildlife, and storing floodwaters. In Alberta, wetlands cover about 21% of the landscape of the province. In Alberta, as elsewhere, wetlands have suffered from human activities and many have...
Factors driving switches in the primary producer communities of shallow lakes of the Boreal Plains, Alberta, CanadaDownload
The mechanisms that contribute to the frequent switching of primary producer communities in shallow lakes on the Boreal Plains of Alberta, Canada were explored. The lakes tend to be clear and macrophyte-rich (61% of lakes) or turbid and phytoplankton-rich (30% of lakes). The study is based on...
Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlandsDownload
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....
Doctoral thesis. Study of determine the cause of the pattern of Ledum groenlandicum in mires (peatlands). Field research centered primarily in two mire systems located in central Alberta. The influence of several major environmental variables on the plant's life cycle was studied.
Marsh reclamation in the oil sands of Alberta: providing benchmarks and models of vegetation developmentDownload
A key objective of the Alberta oil sands industry is to reclaim the post-mined landscape to “equivalent land capability” (Harris 2007). Vitt and Bhatti (2012) proposed a restoration framework for boreal disturbances. They suggested that to increase chances of achieving ecosystem equivalency and...
Methane efflux form boreal wetlands: theory and testing of the ecosystem model ecosys with chamber and tower flux measurementsDownload
A robust model of CH4 emission from terrestrial ecosystems should be capable of simulating the temporal and spatial variability that characterizes field measurements. Such a model should couple a biologically based treatment of microbial CH4 transformations with a physically based treatment of...
On the origin of virtual wetlands by means of computer aided selection or the preservation of favoured places in the struggle for functional wetlandsDownload
To aid in reclamation planning for the Genesee Coal Mine in Alberta, I qualified the pre-mined state of wetlands and measured land use and land cover (LULC) change between 1982 and 2007. A generalized linear model (GLM) was developed to explain the presence of wetlands on the pre-mined...
