Acoustic properties of four central boreal tree species for potential use in instruments
(2023)In resonance wood, acoustic velocity, density profiles, and ring characteristics play an important role. Multiple factors cause variation of these properties, like the difference between juvenile wood and mature wood, ... -
Acoustic wave propagation testing to determine quality in timber and timber products
(2020)Assessing and grading of raw materials in the timber industry is a key factor in the maximization of extracted value. Several different approaches are utilized to measure the quality of standing timber and sawn lumber. ... -
Alternative uses for waste products from biomass burners
(2021)Woody biomass has become an important source of renewable energy throughout the world. A major issue that has risen from the increased use of combustion technology to produce thermal energy is the large amount of waste ... -
Analysis of current and future Low Impact Development sites in Thunder Bay, Ontario
(2017)The rapid spread of urbanization in Thunder Bay has caused the increase of impermeable surfaces and the increase in flood incidents within the city. Another contributing factor to increased flood incidents is due to the ... -
An analysis of northern goshawk prey preferences by biogeoclimatic subzone across coastal British Columbia
(2020)This thesis investigates the dietary preferences of northern goshawk populations in second growth stands on Vancouver Island and the islands of the Johnstone Strait region on the BC Mainland Coast. Prey abundance was ... -
Analysis of using unmanned aerial vehicles in forestry
(2019)Unmanned aerial vehicles are a growing market within the forestry industry. They provide opportunities for enhancement of data collection, monitoring of wildlife, forest fire detection and monitoring, compliance monitoring ... -
Analysis on the influencing factors of forest natural regeneration in northern China
(2021)The purpose of this paper is to clarify that the differences in natural regeneration between the two forests in northern China are caused by precipitation, altitude, temperature, and canopy density. Similarly, the ... -
Analyzing impacts of brush saw and herbicide treatments on branching and stem quality in northern Ontario jack pine plantations
(2020)In an industry where new science is ever-evolving, forest managers must constantly look towards research to guide best practices in achieving the highest quality forest product. Three common silvicultural treatments ... -
Apparent competition and the differing effects of generalist and specialist predators on cervid populations
(2020)Apparent competition is an important ecological function that has been extensively studied in wild cervid populations, but little is known about how to manage it or why some cervid populations are more affected by it ... -
Application of Walki®Biomass cover as a better alternative to plastic mulching
(2022)Mulch is a material that works as a protective layer over the soil so as to retain water and prevent excess evaporation. They are either in the form of continuous sheets like plastic mulch or they come in a shredded form, ... -
Assessing data accessibility and quality: predicting the effect of impervious surfaces on water quality in urban centres on the west coast of Lake Superior
(2020)This research will critically examine the difference in data quality and accessibility between two cities through an analysis of predicting the effect of impervious surfaces on water quality. Through using the Impervious ... -
Assessing progress toward an effectively managed, representative, and well-connected global protected area network
(2022)Protected areas are a cornerstone of conservation efforts to prevent biodiversity loss. Aichi Target 11 of the Convention on Biological Diversity called for the area of protected areas to be increased to 17% of terrestrial ... -
Assessing the feasibility of low-cost unmanned aerial vehicle data collection and automatic tree detection to determine silviculture stand stocking status in BC
(2022)The objective of this research was to evaluate the capabilities and limitations of low-cost UAV-collected silviculture data derived from Digital Aerial Photogrammetric point clouds. Four regenerating forest stands with a ... -
Assessment of black spruce portfolio trial survival and growth and implications for reforestation under climate change
(2018)The purpose of this study is to assess the performance of black spruce seedlings at a genetic trial designed to select seed sources adapted to several climate change scenarios. Height variability among trees is attributed ... -
Assessment of hazard tree/snag detection using drone-based, multi-spectral sensors
(2022)Snags are an integral component of forest ecosystems as they provide habitat for a number of different species and add complexity to vertical forest structure. However, snags also may pose as potential hazards to people ... -
Assessment of lake trout (Salvelinus namaycush) mercury concentration across a gradient of food web complexity and environmental variables
(2023)Exposure to mercury has been linked to health risks in both people and wildlife. In Ontario, mercury pollution is to blame for 85% of the consumption restrictions on fish from inland lakes. Heavy metals like mercury ... -
An assessment of the utility of an unmanned aerial vehicle for measuring tree heights in a jack pine provenance trial
(2020)This independent study is an assessment of the utility of an unmanned aerial vehicle (UAV) for measuring the heights of jack pine (Pinus banksiana) trees in a provenance trial. An electronic hypsometer, the Haglöf Vertex ... -
Assessment using TerrSet geovisualisation of the temporal and spatial effectiveness of the prescribed burn program in re-establishing the oak savannah habitat at the Pinery Provincial Park
(2022)Oak savannah is a plant community of widely spaced deciduous trees with a canopy cover of between 25 to 35%, allowing grasses and other ground cover vegetation to thrive, providing habitats for numerous plant and animal ...
