Effect of Seed Production and Soil Scarification on the Natural Regeneration of a Second-Growth Fir Stand in the Lower St. Lawrence Region
Resource
This study examines the relationship between seed production, soil scarification and seedling establishment in balsam fir ( Abies balsamea [L.] Mill.) and white spruce ( Picea glauca [Moench] Voss)...
Effects of Cell Size and Spacing on Root Density and Field Performance of Container-Reared Black Spruce
Resource
This study examined the effects of nursery rearing in an array of 51 individual fabricated frames that supported a range of six growing cell sizes at 11 plant spacings in all possible combinations. A...
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 Harvesting Methods on Soil Properties and Forest Productivity in Interior British Columbia
Resource
Seven treatment units in three different clearcut blocks in the Golden Forest District were studied to assess overall soil disturbance levels resulting from ground-based harvesting using two methods...
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 Partial Cutting on the Incidences of Tree Wounding, Microbial Succession and Tree Mortality
Resource
One of the challenges of partial cutting operations is minimizing damage to residual trees. In these types of cuts, large pieces of forestry equipment must be manoeuvred in somewhat confined spaces...
Effects of Removal of the Paperpot Container on Growth and Development of Black Spruce Seedlings on a Drained Peatland Clearcut in Northeastern Ontario
Resource
This report discusses the results of a study of 60 black spruce ( Picea mariana [Mill.] B.S.P.) paperpot seedlings, of which half were planted with the paper container removed. Planting was done on a...
Effects of Silvicultural Systems and Vegetation Control on Tree Growth in a Coastal Montane Ecosystem: Seven Year Results
Resource
Technology Transfer Notes are a series of publications focusing on forestry research applications. Technology Transfer Notes offer new techniques, methods, tools and procedures, and deliver research...
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...
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.
