Effects of Elemental Sulfur on Soil pH and Growth of Saskatoon Berry (Amelanchier alnifolia) and Beaked Hazelnut (Corylus cornuta) Seedlings
Resource
The land disturbed by open-pit oil sands mining must be restored to support the survival and growth of native boreal plants. Because tailings sand and sodic shale overburden are commonly used as an...
Effects of Fire Severity and Woody Debris on Tree Regeneration for Exploratory Well Pads in Jack Pine (Pinus banksiana) Forests
Resource
This study compares the effects of wildfire and local variation in the amount of residual woody debris on natural regeneration in jack pine on exploratory well pads in Alberta’s boreal forest.
Effects of Narrow Linear Disturbances on Light and Wind Patterns in Fragmented Boreal Forests in Northeastern Alberta
Resource
Forest fragmentation threatens forest biodiversity and ecosystem function. One of the concerns relates to increases in edge effects, which among other things affects the forest microclimate that...
Effects of Natural Land Cover, Anthropogenic Disturbance, Space, and Climate on Oribatid Mite Communities in Canada’s Oil Sands Region
Resource
Soil contains a diverse fauna and microflora that are vital for maintaining healthy soils and their various ecosystem services. Oribatid mites are typically highly abundant arthropods in the soil and...
Effects of Wildfire and Soil Compaction on Recovery of Narrow Linear Disturbances in Upland Mesic Boreal Forests
Resource
Energy exploration has led to fragmentation of habitats worldwide. In boreal forests of Alberta, Canada narrow clear-cut linear disturbances (3–14 m wide) called seismic lines are often the largest...
Elk Winter Food Habits and Forage Quality Along the Eastern Slopes of Alberta (A Review)
Resource
A review of the limited number of studies on elk winter food habits along the Eastern Slopes of Alberta shows that elk prefer grasses and grasslike plants over shrubs. When available, rough fescue (...

EMEND for Schools: 360 Video and Teaching Resources
Resource
The Emend for Schools: 360° Video EMEND Tour Teachers Resource is a full lesson plan and 360 immersive and interactive video teaching tool, including a teacher lesson plan and student workbook aligned...
Emerging Issues – Land Degradation
Resource
Problems associated with soil degradation have, in some parts of Canada, reached crisis proportions. Combatting these problems is a complex task involving the consideration of social, economic, and...
Empowering Indigenous Resilience With Treatment Wetlands
Resource
Many Indigenous communities in Canada have little or no access to water treatment facilities. Treatment wetlands could offer a nature-based solution with localized and decentralized wastewater...
Enhanced Revegetation and Reclamation of Oil Sands Disturbed Sites Using Actinorhizal and Mycorrhizal Biotechnology
Resource
Preliminary results, after two growth seasons, show promise in the use of pre-inoculated seedlings in enhancing growth and establishment of alders and conifers on oil sands reclamation sites.
Environmental and Management Drivers of Carbon Dioxide and Methane Emissions From Actively-Extracted Peatlands in Alberta, Canada
Resource
The installation of drainage ditches and removal of vegetation in preparation for vacuum harvesting alters the carbon dynamics of peatlands. However, we lack the measurements to understand the spatial...
Establishment and Vegetation Survey of 16 Pinus banksiana-dominated Permanent Plots for the Athabasca Oil Sands Ecological Monitoring Project in 1981
Resource
16 undisturbed, 5-ha, permanent plots dominated by Pinus banksiana (jack pine) were established along an impingement gradient of atmospheric emissions from oil sands processing plants
Estimate of the Maximum Probable Precipitation for Alberta River Basins
Resource
Point measurements of maximum depth showed that over 50% of the rainstorms occur in June and July, with only a small percentage in April (5.6) and September (10. 1).
Estimating Lichen Biomass in Forests and Peatlands of Northwestern Canada in a Changing Climate
Resource
Climate warming in the North could lead to lichen decline within critical woodland caribou habitat. We used repeat measurements of sixty-nine plots over ten years (2007–2008 and 2017–2018) to assess...
Ethics in Community Based Monitoring and Knowledge Coproduction
Resource
A two-day workshop “Ethical Space for Knowledge Coproduction: Workshop on Ethics in Community Based Monitoring” brought together 60 people from February 12-13, 2019, at the University of Alberta on...
Evaluating Functional Recovery of Habitat for Threatened Woodland Caribou
Resource
Habitat restoration is a core element for the recovery of many declining species. In western Canada, habitat restoration for the recovery of woodland caribou is focused on linear features (LFs)...
