Determining genetic resistance to jack pine budworm defoliation in jack pine from different geographic seed sources across Ontario
(2020)Jack pine budworm is an outbreak insect that defoliates jack pine forests across Canada. While it is a native species, the outbreaks can have severe economic impacts, such as loss of timber volume and increased risk of ... -
Determining the accuracy of terrestrial LiDAR on red pine
(2019)This paper reviews the capabilities of the FARO Terrestrial LiDAR technology to produce accurate forest measurements. The study was conducted on single Red Pine trees in Northern Ontario. Field measurements were compared ... -
Differences in density measures between TreeAzin® injected and non-injected ash wood
(2021)This undergraduate thesis explores an observation made by the City of Thunder Bay’s urban forestry department staff of TreeAzin injected Green Ash tree’s limbs and branches failing shortly after being injected. The ... -
Differences in dung beetle (Coleoptera: Scarabaeinae) assemblages in different habitat types and habitat patches within the Verde Sumaco forest, Ecuador
(2019)Scarabaeinae, the dung-eating beetle subfamily, comprises keystone species that perform a host of ecological functions. They are easily surveyed and respond to habitat change, making them suitable indicators of effects of ... -
Differential treatment of boreal forest biome by forest stewardship council
(2017)This thesis examines the conduct of Forest Stewardship Council (FSC) regarding the certification stringency in the boreal biome. Certification is less stringent in Russia as compared to other boreal nations; Canada, ... -
Diversity of life history characteristics of Lake Superior migratory rainbow trout
(2017)Rainbow Trout (Oncorhynchus mykiss) have been present in the Great Lakes since their introduction in the late 1800’s (Clarkson et al. 1997). These fish have naturalized many streams and have established naturally reproducing ... -
Does Canada lynx trapper harvest track population cycles? A review of data from 1973 to 2016 in Ontario's sixteen northern forest districts
(2019)The Canada lynx (Lynx canadensis) has been widely studied for its strong interaction with the snowshoe hare (Lepus americanus), and the lynx exhibits a slightly lagged, 10-year population cycle dependent on the hare ... -
The dynamic effects of tree species diversity on nitrogen in soil
(2019)The availability of nitrogen in soil is one of the most important factors for tree growth. Although tree species mixtures are known to increase forest productivity, it remains unclear how they affect soil nitrogen. In ... -
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 ...
