Annosus Root and Butt Rot Caused by Heterobasidion Irregular in Pines
Resource
Annosus root and butt rot appeared in Quebec relatively recently and its progression still seems to be fairly limited. However, the capacity of this disease to spread over long distances and the value...
Annual Aboveground Carbon Uptake Enhancements from Assisted Gene Flow in Boreal Black Spruce Forests Are Not Long-Lasting
Resource
Assisted gene flow between populations has been proposed as an adaptive forest management strategy that could contribute to the sequestration of carbon. Here we provide an assessment of the mitigation...
Applications of Simulation-Based Burn Probability Modelling: A Review
Resource
Wildland fire scientists and land managers working in fire-prone areas require spatial estimates of wildfire potential. To fulfill this need, a simulation-modelling approach was developed whereby...
Are Climates in Canada and the United States Suitable for the European Spruce Bark Beetle, Ips typographus, and its Fungal Associate, Endoconidiophora polonica?
Resource
Invasions of exotic forest insects and pathogens can devastate evolutionarily naïve habitats and could cause irreversible changes to urban and natural ecosystems. Given the ever-increasing volume of...
Assessing the Climate Suitability and Potential Economic Impacts of Oak Wilt in Canada
Resource
Oak wilt is a disease that kills oak trees and is caused by a fungus named Bretziella fagacearum. Though not currently found in Canada, our distribution models indicate that suitable climate...
Assessing the Cumulative Effects of Environmental Change on Wildlife Harvesting Areas in the Inuvialuit Settlement Region through Spatial Analysis and Community-based Research
Resource
Arctic ecosystems are undergoing rapid environmental transformations. Climate change is affecting permafrost temperature, vegetation structure, and wildlife populations, and increasing human...
Assessing the Impact of Fine-Scale Structure on Predicting Wood Fibre Attributes of Boreal Conifer Trees and Forest Plots
Resource
Information about wood fibre attributes (WFA) is important for optimizing forest resource management and increasing the competitiveness of the sector. Many factors influence WFA at both the plot (e.g...
Assessing the Influence of Climate on the Growth Rate of Boreal Tree Species in Northeastern Canada Through Long Term Permanent Sample Plot Datasets
Resource
Climate has a considerable influence on tree growth. Forest managers benefit from the empirical study of the historic relationship between climatic variables and tree growth to support forest...
Assessment of Potential for Remote Sensing Detection of Bark Beetle-Infested Areas During Green Attack: A Literature Review
Resource
Changes observed in the foliage of trees killed by bark beetles are usually described in terms of stages that have been related to a specific timeframe. The “green attack” stage is the period of time...
Automated Characterization of Forest Canopy Vertical Layering for Predicting Forest Inventory Attributes by Layer Using Airborne LiDAR Data
Resource
Forest canopy vertical layering influences stand development and yield and is critical information for forest management planning and wood supply analysis. It is also relevant for other applications...
Balsam Fir-Yellow Birch Forest Succession in the Lower St. Lawrence Region
Resource
In Quebec, the bioclimatic zone of balsam fir-yellow birch covers an area of 94,768 km 2. Some of the forest cover types in the area, such as balsam fir-yellow birch, are among the most productive in...
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...
BERA News Fall 2022
Resource
Understanding how birds respond to landscape disturbance is key to effective restoration. Two studies used non-invasive microphone arrays to determine the exact locations of singing individuals in the...
BERA News Spring 2022
Resource
Mounding is a common restoration technique designed to improve microsite conditions for planted seedlings in wetlands. There are a variety of strategies for constructing mounds, though, and how mounds...
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...
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 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...
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...
