Effect of Forest Understorey Stand Density on Woodland Caribou Habitat Use
Resource
Woodland caribou ( Rangifer tarandus caribou) are considered to preferentially use older forests that provide abundant terrestrial lichen forage and refuge from predators. However, structural...
Effect of Forest Understory Stand Density on Woodland Caribou (Rangifer tarandus caribou) Habitat Selection
Resource
Woodland caribou ( Rangifer tarandus caribou (Gmelin, 1788)) use older forests that provide abundant terrestrial lichen forage and refuge from predators. However, forest structural characteristics...
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 Oil and Gas Development on Grassland Birds
Resource
Grassland bird populations have declined significantly over the past century, largely due to anthropogenic habitat loss and degradation. It is estimated that approximate 20% of original native...
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 (...

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...
End of the Road: Short-term Responses of a Large Mammal Community to Forest Road Decommissioning
Resource
This resource is available on an external database and may require a paid subscription to access it. It is included on the CCLM to support our goal of capturing and sharing the breadth of all...
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
