Ecological and economic values of public trees from the Manitou tree inventory
(2020)Urban trees are an underappreciated aspect to urban communities and contribute valuable ecosystem services. As of November 2017, the emerald ash borer (Agrilus planipennis), an invasive beetle from Asia had been found in ... -
An economic analysis of an American ginseng growing operation in a woodlot in Janetville, Ontario
(2018)American ginseng (Panax quinquefolius) has been valued for centuries as a medicine, particularly in Asian cultures. It is highly valuable, and as a result it has been poached to endangered levels throughout much of its ... -
Economic feasibility of ground-based steep slope logging using winch-assist technologies
(2018)This thesis examines the use of winch-assist technologies in logging operations in the interior of British Columbia. The data used for this thesis is from a contractor’s (located in Central B.C.) professional judgment ... -
Economic risk analysis of the emerald ash borer on the Thunder Bay campus of Lakehead University
(2018)In addition to their beauty, these trees contribute valuable ecosystem services. As of June 2016 the emerald ash borer, an invasive beetle from Asia, has been found in Thunder Bay and has the potential to kill every ash ... -
The economic value of recovering the town of Oakville's urban forest after the impacts of the emerald ash borer
(2019)The Town of Oakville is responsible for maintaining some 2,016,500 city trees planted within boulevards on the city’s streets (UFORE 2016). Prior to the emerald ash borer, ash trees represented the top 5 most trees planted ... -
Ecotypic variation of black spruce in northwestern Ontario
(2020)The success of reforestation can be improved by selecting the appropriate seed source for the site type. However, not much is known about the differences in using upland versus lowland black spruce seed sources when ... -
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 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 ...
