The effect of climate change on mountain pine beetle (Dendroctonus ponderosae Hopkins) in Western Canada
(2021)The mountain pine beetle, Dendroctonus ponderosae, (MPB) is the largest forest disturbance factor throughout its range in North America. The most recent MPB outbreak began in the 1990s and has resulted in an approximate ... -
The effect of ectomycorrhizal fungus Hebeloma longicaudum on drought stress of Pinus banksiana seedlings
(2023)This study looks at the influence of the ectomycorrhizal fungus Hebeloma longicaudum to form associations and impact growth of jack pine seedlings under simulated drought conditions. Four treatment groups of jack pine ... -
Effect of harvest intensity on soil carbon and nutrients across global forests: a meta-analysis
(2018)Logging residues can retain important nutrients for tree growth after biomass harvesting. However, increasing the harvest intensity may decrease soil nutrient stores stocks and affect biomass productivity. Using 2207 ... -
Effect of spacing management on growth and commercial logging of red pine
(2021)To maximize utilization of the forest resource, spacing management always plays an important role in tree planting. It will influence tree height, diameter, mortality, self-pruning, and most importantly, early growth ... -
The effect of tree size on the delivered wood cost in Northern Ontario
(2020)To determine the effects that tree size has on the delivered wood cost, data was collected from existing literature on: average tree size (m3), average off road transport distance, volume per hectare (m3/ha), logging chance ... -
Effect of tree species diversity on species growth rate in the Saskatchewan boreal forest
(2023)Diverse ecosystems are crucial to combating climate change. This study aims to examine the impacts of tree species diversity on growth rate of seven boreal tree species. Data from permanent sample plots located in the ... -
The effects different commercial thinning treatments have on black spruce diameter, height, basal area and volume
(2023)Commercial thinning is a potential opportunity for forest managers to realize mid rotation wood volume while stimulating increased growth of residual trees for the final harvest. The practice of commercial thinning is, ... -
The effects of a forest fires on water flow and quality in lakes surrounding a Northern Ontario mine
(2023)Water quality and quantity can be greatly impacted following a forest fire, but fire impacts can vary based on fire intensity, watershed topography, and post-fire precipitation events. Forest fires are an important ... -
The effects of biogeographic factors on the persistence and distribution of the common five-lined skink in Southern Ontario
(2018)The management of biogeographic factors associated with species at risk populations is an excellent conservation tool if the effects of such factors are thoroughly understood. Biogeographic factors, or habitats, such as ... -
The effects of competition on underplanted juvenile white spruce in fill blocks in northern Alberta
(2020)This paper examined the effects of competition on juvenile white spruce growth planted in the understory of lodgepole pine on a mixedwood boreal site. Growth and success of planted white spruce seedlings were investigated ... -
Effects of environmental factors on seed germination
(2019)Detailed understanding of the environmental conditions required for the germination and growth of tree seeds is an important prerequisite for the formulation of comprehensive and sustainable forest development strategies, ... -
Effects of forest fire on watershed ecosystem
(2019)Global warming has increased the frequency of forest fires and droughts, which have had a number of effects on the hydrologic ecosystems of watersheds`. Therefore, the influence of forest fires on forest watersheds and ... -
Effects of Lalrise Vita. Bacillus velezensis on Pinus banksiana and Picea mariana
(2022)Jack pine, Pinus banksisana, and black spruce, Picea mariana, are the top two species harvested and planted in the boreal forest of Canada. Sustainable forest management incorporates greenhouses and artificial fertilizers ... -
Effects of mechanical site preparation on the growth of Jack Pine (Pinus banksiana)
(2018)The boreal forest in Canada provides a large volume of timber for Canadians and other countries year after year and effective silviculture is the key to sustainable harvesting. Site preparation can be a critical step in ... -
The effects of mechanical site preparation, unscarified and refill land types on the growth and establishment of planted seedlings
(2023)This study examines the effects of different site types of tree planting blocks on the growth and establishment of planted seedlings within the Black Spruce Forest, north of Thunder Bay, Ontario. Measurements of planted ... -
The effects of nanosilver on northern pike
(2018)Nanosilver (nAg) is an effective anti-microbial agent that is being increasingly used in consumer products. With such an expansive list of products incorporating nAg, the risk of environmental release is high. Studies ... -
The effects of nitrogen Rate On seedlings growth in Picea Mariana
(2017)Nitrogen (N) is critically important for plant growth and development. The objective of this thesis is to examine how different rates of Nitrogen affect the seedling growth in black spruce (Picea mariana Mill.). This ... -
Effects of past grazing and trampling on soil nutrients at Stanley Hill Bison, Kakabeka Falls, Ontario
(2020)Global studies indicate that ungulates can have negative influences on soil quality and directly affect soil nutrient availability. This thesis examines the effects of past cattle grazing and current bison grazing on ... -
The effects of plantation spacing on Pinus resinosa wood density variation and managing for increased carbon sequestration
(2020)Pinus resinosa is found throughout a large portion of eastern North America. Dating back to the early settlement era, wood utilization has varied from solely infrastructure to bioenergy and carbon sequestration. Although ... -
Effects of road construction cost in determining whether a block should be harvested in the summer or winter on the Romeo Malette Forest
(2022)Permanent and temporary forest roads are key infrastructures for the removal of raw forest products. Ensuring an efficient road network is laid out and proper construction methods are chosen will aid in reducing the total ...
