Symptomology and Threshold Levels of Air Pollutant Injury to Vegetation, 1979-80
Resource
A number of coniferous and deciduous species that had been growing on the Suncor tailings sand dike for five to seven years were fumigated with 0.34 ppm SO2 under controlled environmental conditions
Temperature, Moisture and Freeze–thaw Controls on CO2 Production in Soil Incubations From Northern Peatlands
Resource
Peat accumulation in high latitude wetlands represents a natural long-term carbon sink, resulting from the cumulative excess of growing season net ecosystem production over non-growing season (NGS)...
Temporal Trends of Ecosystem Development on Different Site Types in Reclaimed Boreal Forests
Resource
Forest development after land reclamation in the oil sands mining region of northern Alberta, Canada was assessed using long-term monitoring plots from both reclaimed and natural forests. The metrics...
Terrestrial Lidar Scanners Help to Better Predict Wood Quality by Using Tree Structure.
Resource
This fibre fact demonstrates that fine-scale structural information derived from t-lidar and new modeling techniques can improve wood fibre attribute predictions.
The 2023 Wildfire Season in Québec: An Overview of Extreme Conditions, Impacts, Lessons Learned and Considerations for the Future
Resource
Abstract The 2023 wildfire season in Québec set records due to extreme warm and dry conditions, burning 4.5 million hectares and indicating persistent and escalating impacts associated with climate...
The Autecology of Major Tree Species in the North Central Region of Ontario
Resource
This report provides information on the general autecology of 12 common tree species occurring in the North Central (NC) Region of Ontario.
The Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
The Canadian National Vegetation Classification: Principles, Methods and Status
Resource
The Canadian National Vegetation Classification (CNVC) is an ecological classification of natural vegetation communities in Canada. It provides a framework for describing patterns of vegetation at...
The Cryptophagidae of Canada and the Northern United States of America
Resource
This review of Cryptophagidae of Canada and the Northern United States (US) covers 142 species among the following genera: Caenoscelis (6 species), Antherophagus (4), Cryptophagus (33), Henoticus (4)...
The Direct and Habitat-mediated Influence of Climate on the Biogeography of Boreal Caribou in Canada
Resource
Effective species conservation efforts require insight into whether a species’ extent of occurrence may shift due to changing climate, habitat loss, or both. The extent of occurrence of the threatened...
The DNA Barcode: A Unique Identifier for Pathogenic Forest Fungi
Resource
In the era of molecular biology, DNA barcoding is being used to fill gaps in taxonomy and confirm findings obtained through traditional approaches based on morphological differences between species...
The Effects of Black Spruce Fuel Management on Surface Fuel Condition and Peat Burn Severity in an Experimental Fire
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...
The Effects of Soil Temperature and Site Preparation on Subalpine and Boreal Tree Species: A Bibliography
Resource
In forestry, the purpose of site preparation is to ameliorate environmental conditions which limit tree seedling survival and growth. In subalpine and boreal forests, low soil temperature in...
The Essential Carbon Service Provided by Northern Peatlands
Resource
Northern peatlands have cooled the global climate by accumulating large quantities of soil carbon (C) over thousands of years. Maintaining the C sink function of these peatlands and their immense long...
The FastTRAC to First-Rate Seeds
Resource
(Fast Tests for Rating and Amelioration of Conifer) – A collaboration among CWFC researchers, academia, government and industry transforms traditional tree breeding programs by improving genetic...
The Impact of Fuel Treatments on Wildfire Behavior in North American Boreal Fuels: A Simulation Study Using FIRETEC
Resource
Current methods of predicting fire spread in Canadian forests are suited to large wildfires that spread through natural forests. Recently, the use of mechanical and thinning treatments of forests in...
The Influence of Forest Harvesting Activities on Seismic Line Tree and Shrub Regeneration in Upland Mixedwood Boreal Forests
Resource
Alberta’s forests are becoming increasingly disturbed and fragmented by the cumulative effects of anthropogenic disturbances exacerbated by the enduring footprint of seismic lines on the landscape...
The Multisource Vegetation Inventory (MVI): A Satellite-Based Forest Inventory for the Northwest Territories Taiga Plains
Resource
Wall-to-wall 30 m raster maps of broad forest type, stand height, crown closure, stand volume, total volume, aboveground biomass, and stand age were created for a ~400,000 km2 area, validated with independent data, and generalized into a polygon GIS layer resembling a traditional FI map. The MVI project showed that a reasonably accurate FI map for large, remote, predominantly non-inventoried boreal regions can be obtained at a low cost by combining limited field data with remote sensing data from multiple sources.
The Natural Defences of Trees Against Injury and Disease
Resource
Trees are constantly exposed to a multitude of micro-organisms, but only a few are capable of causing disease. When trees come under attack from micro-organisms, their primary line of defence is a...
