Baseline Condition of Jack Pine Biomonitoring Plots in the Athabasca Oil Sands Area, 1976-1977
Resource
No measureable air pollutant effect was observed on either vascular or lichen communities at any site even though significantly high tissue pollutant concentrations were documented within 10km of GCOS
Beech Scale
Resource
Beech scale is an introduced insect that damages beech trees; this damage can lead to beech bark disease. The insect was introduced to North America in the late 1800’s and has spread throughout...
Biomass and Root Stem Production of a Colony-forming Willow (Salix interior) on Highly Disturbed, Low Fertility Sites
Resource
This study describes biomass production, colony formation, and clonal spread via root stems of a wide-ranging North American willow species, Salix interior (INT), one of the few willows that can...
Biomass Estimates for Major Boreal Forest Species in West-Central Canada
Resource
Forest biomass is the second-largest renewable energy resource in Canada, representing a major pool in the global carbon budget, but better estimates of forest biomass are needed. In the 1980s...
Biophysical Determinants of Shifting Tundra Vegetation Productivity in the Beaufort Delta Region of Canada
Resource
Temperature increases across the circumpolar north have driven rapid increases in vegetation productivity, often described as ‘greening’. These changes have been widespread, but spatial variation in...
Biting Flies and Activity of Caribou in the Boreal Forest
Resource
Habitat loss has been implicated in the decline of forest-dwelling caribou ( Rangifer tarandus caribou), but it is unknown how biting insects, potentially important components of boreal forest habitat...
Black Spruce Seeds Short-Lived on Boreal Forest Seedbeds
Resource
Viability of black spruce ( Picea mariana [Mill.] B.S.P.) seeds after dispersal in nature or by man may be a crucial factor affecting regeneration of the species on boreal forest seedbeds. Some...
Boreal Caribou Can Coexist with Natural but Not Industrial Disturbances
Resource
Abstract: For species at risk, it is important that demographic models be consistent with our most recent knowledge because alternate model versions can have differing predictions for wildlife and...
Boreal Mixedwood Forest Potential for Carbon Uptake and Storage
Resource
The boreal mixedwood forest ecosystem includes both coniferous and deciduous tree species and is a common and widespread ecosystem in the Canadian boreal forest resulting from harvesting, forest fires...

Can satellite imagery be used to assess forest regeneration on seismic lines? Webinar with Angeline Van Dongen from Natural Resources Canada, Canadian Forest Service.
Breeding Strategies of Important Tree Species in Canada: Papers Presented at the Workshop
Resource
Breeding programs and strategies for four major tree species of Canada are presented, including Douglas-fir ( Pseudotsuga menziesii (Mirb.) Franco), jack pine ( Pinus banksiana Lamb), the larch...
Bringing Forests Back After Oil and Gas Disturbances: An Experiment Testing Emerging Techniques to Grow Trees on Seismic Lines.
Resource
This publication discusses the restoration of treed peatlands after disturbances caused by oil and gas activities, particularly in areas where seismic lines have been created. Seismic lines are...
Bur Oak (Quercus Macrocarpa) Biomass Production on a Former Coal Mine Site: Positive Effects of Coppicing on Rapid Recovery of Growth and Yield
Resource
Ten-year-old bur oak ( Quercus macrocarpa Michx.) saplings established on the exposed, infertile, treeless barrens of a former coal mine site in New Brunswick, Canada, were harvested to assess the...
Buried Wood Effects on Macronutrient Supply and Microbial Activity and Metabolic Potential in Different Oil Sands Reclamation Soils in Northern Alberta
Resource
Buried wood is an important yet understudied component of natural and anthropogenic soils. Nutrient immobilization as a response to wood addition during oil sands' reclamation may be a concern since...
Burned Timber: Salvage Logging to Promote Regeneration
Resource
To make up for timber losses caused by fire, salvage logging of burned timber is an economically attractive option. Improved logging practices could promote the establishment of regeneration while...
Butternut: What Are Its Odds Against Canker?
Resource
The continuing spread of butternut canker constitutes the greatest threat to the survival of butternut trees, which have been protected under the Species at Risk Act since 2005. Furthermore, growing...
Calcareous Soils, Their Properties and Potential Limitations to Conifer Growth in Southeastern British Columbia and Western Alberta: A Literature Review
Resource
This report is a review of published literature on calcareous soils and their role in the productivity of coniferous forests in southwestern British Columbia and western Alberta. Definitions, origins...
