Edge effects of road material and compaction on the regeneration of jack pine in the English River Forest
(2018)There is potentially a considerable proportion of harvestable forest area experiencing road edge effects. It may be important to understand these effects and how trees respond to them to improve forest growth modeling ... -
The effect of Bacillus thuringiensis serotype kurstaki (Btk) as an insecticide on jack pine budworm in the 2019 Northern Ontario spray program in comparison to historical use
(2020)Bacillus thuringiensis (Bt) has been used historically as an insecticide by the Ontario Ministry of Natural Resources and Forestry (OMNRF) to suppress jack pine budworm populations in dense outbreaks. In some previous ... -
The effect of block composition on the severity of spruce beetle (Dendroctonus rufipennis) damage in northern British Columbia
(2021)The spruce beetle (Dendroctonus rufipennis) is a natural part of the western North American landscape, feeding on the phloem of trees in the Picea genus. The spruce beetle generally feeds on downed trees but can also ... -
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 ... -
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 ... -
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 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 ... -
Effects of soil microorganisms on bamboo (Phyllostachys praecon C. D. Chu et C. S. Chao 'Prevernalis) growth
(2021)Soil microorganisms and plants together form a stable dynamic system in which they interact and influence each other. The growth and development of plants provide nutrients to the soil microorganisms, which in turn promote ... -
Effects of species composition and season change on fine root length increase with stand development in Northwest Ontario
(2018)The root length is an important indicator to reflect the growth characteristics of the tree, but the root length is difficult to obtain through direct measurement, and the root as a sensitive organ of plants can indirectly ...
