Stream Crossings in the Western Boreal Forest: Assessing Impacts and Prioritizing Restoration for Native Freshwater Fishes
DownloadFall 2015
Growing anthropogenic development in response to rising demands for natural resources is a major concern for freshwater fish, particularly in resource rich regions such as Canada’s boreal forest. Expanding networks of industrial resource roads has led to the installation of hundreds of thousands...

The effects of underplanted white spruce on understory environment and vegetation in aspen-dominated stands of the western boreal forest
DownloadSpring 2012
In the boreal forest of Alberta, Canada, underplanting white spruce (Picea glauca) in aspen (Populus tremuloides) forests attempts to address concerns about "unmixing the mixedwoods". Important ecological differences exist between mixedwood, broadleaf and conifer forests. I studied changes in...

The potential of forest floor transfer for the reclamation of boreal forest understory plant communities
DownloadFall 2011
We examined a direct forest floor transfer reclamation technique to establish a native boreal forest understory plant community on a reclamation site at a coal mine. Forest floor material was salvaged from an aspen-dominated (Populus tremuloides Michx.) donor forest at two depths (15 and 40 cm)...

Fall 2017
Legacy propagule banks of salvaged topsoils are excellent sources of plant propagules for reclamation of mine sites. However, prior studies show that less than 50% of species found in original propagule banks actually establish. We hypothesize that the expression of this legacy propagule bank is...

The Structure and Dynamics of Fish Isotopic and Trophic Niches in Natural Lakes and Constructed Fisheries Offsets in the Alberta Oil Sands
DownloadFall 2022
Habitat offsets, where damages to natural ecosystems caused by socio-economic development projects are compensated for by the construction or restoration of other ecosystems, can contribute to biological conservation when implemented properly. But, large uncertainties remain surrounding our...

The use of peat applications and Carex aquatilis for peatland reclamation on post mined landscapes in northern Alberta, Canada
DownloadFall 2018
I investigated peatland reclamation factors in a wetland built on a former open-pit oil sands mine in northern Alberta, Canada. The primary research objectives were to investigate the persistence of peat placed in a newly constructed wetland, the survival and establishment of Carex aquatilis...

Trace elements in berries collected near upgraders and open pit mines in the Athabasca Bituminous Sands Region (ABSR): distinguishing atmospheric dust deposition from plant uptake
DownloadFall 2019
Bitumen mining and upgrading operations in the Athabasca Bituminous Sands Region (ABSR) may lead to increased concentrations of trace elements in the surrounding environment. Elevated concentrations of potentially toxic trace elements could pose a risk to local indigenous communities through the...

Spring 2016
Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...

Spring 2010
This research determined if woody debris amendments facilitate land reclamation after oil sands mining. Specifically, it assessed if woody debris affects vegetation cover and richness, woody species survival and abundance, soil nutrients, temperature and water, microbial biomass carbon and...

Water availability and understory influence on tree growth in reclaimed forest ecosystems, Athabasca oil sands region, Alberta, Canada
DownloadFall 2015
Reclaimed forest ecosystems in the Athabasca oil sands region (AOSR) have limiting factors to growth that can result in poor tree performance, as indicated by stunted growth, foliar discolouration and needle dropping, and ultimately threaten reclamation success. Indicators of reclamation success...
