Novel Aerial Photography as an Aid to Sampling Secondary Structure in Pine Stands
Resource
This project describes a new method for sampling secondary structure in beetle-attacked pine stands and reports on a test of its accuracy. The method consists of interpreting aerial photos taken when...
Oak Wilt
Resource
Oak wilt is a tree disease caused by the fungus Bretziella fagacearum. The fungus is widespread throughout the eastern United States and, as of 2021, found within 600 m of the Canadian border near...
Old-Growth Forests in Canada
Resource
This pamphlet is about old-growth forests in Canada. It includes a map that shows the Forest Regions of Canada and provides examples of different old-growth forest types in some of these regions.
Opportunities and Limitations of Thinning to Increase Resistance and Resilience of Trees and Forests to Global Change
Resource
We reviewed recent literature to identify the positive and negative effects of thinning on both stand- and treelevel resistance and resilience to four stressors that are expected to increase in...
Optisource: A Tool for Optimizing Seed Transfer
Resource
Can seedlings intended for reforestation be planted anywhere, regardless of the seed source from which they were obtained? The Optisource software was developed to help forest managers answer this...
Peat Loss Collocates with a Threshold in Plant–Mycorrhizal Associations in Drained Peatlands Encroached by Trees
Resource
Drainage-induced encroachment by trees may have major effects on the carbon balance of northern peatlands, and responses of microbial communities are likely to play a central mechanistic role. We...
Peatland Drainage and Improvement Program (Phase 2): Controlling Water Table Levels to Enhance Tree Establishment and Growth
Resource
Three experimental forest drainage sites were established in Alberta’s boreal forest to determine the effects of lowered water tables on soils, local hydrology, ground vegetation composition and tree...
Peatland Restoration Increases Water Storage and Attenuates Downstream Stormflow but Does Not Guarantee an Immediate Reversal of Long-term Ecohydrological Degradation
Resource
Peatland restoration is experiencing a global upsurge as a tool to protect and provide various ecosystem services. As the range of peatland types being restored diversifies, do previous findings...
Peatlands Promote Fire Refugia In Boreal Forests Of Northern Alberta, Canada
Resource
Abstract In the boreal forests of North America, large wildfires often leave residual patches of unburned vegetation, termed fire refugia, which can affect post-fire ecosystem processes. Although...
Peatlands Reduce Fire Severity and Promote Fire Refugia in Boreal Forests
News
Contact
In the boreal biome of North America, large wildfires usually leave behind residual patches of unburned vegetation, termed refugia, which can strongly affect post-fire ecosystem processes. While...
Petawawa Research Forest: Applied Science at its Finest!
Resource
Since 1918, forest researchers have used the Petawawa Research Forest to establish long term experiments and have collected data using varied and innovative techniques to learn how trees grow within...
Physiology and Mechanisms of Airborne Pollutant Injury to Vegetation, 1979-80
Resource
Appreciable changes in biochemical functions in an epiphytic lichen, Evernia mesomorpha, were observed in response to controlled SO2 exposures even at a very low SO2 concentration (0.1 ppm)
Phytoremediation Efficacy of Salix discolor and S. eriocephela on Adjacent Acidic Clay and Shale Overburden on a Former Mine Site: Growth, Soil, and Foliage Traits
Resource
Plants regularly experience suboptimal environments, but this can be particularly acute on highly disturbed mine sites such as the extensive coal mine spoils in central New Brunswick. Willows have...
