An Alternate Indicator System for Nutrient Supply as Part of Ecosystem Function, a Component of Reclamation Success in the Athabasca Oil Sands Region
DownloadFall 2017
Northeastern Alberta faces the challenges of reclaiming a vast area that has been disturbed my oil sands mining, cumulatively 896 km2 and increasing as of December 2013. The limited resources available for reclamation and expensive costs of undertaking the process necessitates that reclamation be...

An Investigation of Potential Weed Management Practices and Multivariate Assessment Parameters for Alberta's Oil Sands Reclamation Efforts
DownloadSpring 2018
Reclamation efforts that promote the re-establishment of native tree and plant communities subsequent of large-scale oil sands mining land disturbances are crucial in restoring natural ecosystems. It is important that reclamation procedures capable of facilitating the establishment of native...

Assessing the long-term impact of acid deposition and the risk of soil acidification in boreal forests in the Athabasca oil sands region in Alberta, Canada
DownloadFall 2012
Significant amounts of SO2 and NOx have been emitted from the Athabasca oil sands region (AOSR) in Alberta, Canada, in the past several decades. The impact of acid deposition on forest ecosystems and the risk of soil acidification were assessed in jack pine (Pinus banksiana) and trembling aspen...

Developing and testing methods to assess species extinction risk and ecosystem degeneration
DownloadFall 2016
Species worldwide are becoming increasingly threatened due to the rapid changes in climate and land use induced by human activities. The loss of species threatens the provision of food, goods and many other ecosystem services essential to the sustainability and well-being of human society. It is...

Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...

Spring 2012
This study examined the potential of using conifer seedlings Picea glauca and Pinus banksiana inoculated with ectomycorrhizal (ECM) fungi to improve revegetation success and plant establishment in reclaimed oil sands mining sites. Mycorrhizal inoculum potential of the reclamation soils was low...

Increasing wildfire growth modelling decision support using ensemble weather forecasts over the province of Alberta, Canada
DownloadFall 2015
Across Alberta, wildfires ignite each fire season and a small number achieve a size greater than 100 hectares, which account for the vast majority of the area burned. These fires often require large suppression efforts that include wildfire growth simulation modelling in order to understand their...

Marsh reclamation in the oil sands of Alberta: providing benchmarks and models of vegetation development
DownloadFall 2014
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...

In many regions of the world, fires are the primary environmental disturbance producing a mosaic of burned and unburned patches varying at temporal and spatial scales and providing a variety of ecosystem services. Fire perimeters mark the separation between the burned and unburned matrix of a...

Tree size and tree height are two essential quantities to measure structure and productivity of forest stands. As such, they encourage predictability in changes among tree growth patterns and are fundamental to developing forest management plans. Tree height and size (commonly measured as...
