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, ... -
Increasing fruit production in wild populations of pawpaw (Asimina Triloba (L) Dunal) trees in southern Ontario
(2023)The pawpaw (Asimina triloba (L) Dunal) is a unique native understory tree species found in the Deciduous and Carolinian forest regions in Southern Ontario. It is at the edge of its range in Ontario, most of the population ... -
Investigation of adaptive variation of black spruce in 29-year height growth of Black Spruce in a northwestern Ontario provenance trial
(2023)Seed sources from across northwestern Ontario were used to establish a black spruce provenance trial at the former Thunder Bay Forest Nursery located on 25th Sideroad, Thunder Bay. The heights of these trees were measured ... -
The use of citizen science data to predict the winter distribution of the snowy owl in Ontario
(2023)As an Anishinaabe person and environmental scientist, I feel I have an inherent duty to be a steward of the environment. I chose to conduct research on Snowy Owls after learning about the conservation issues affecting ... -
Urban forest management: evaluating the benefits and options for replacing declining urban ash tress, and value-added potential of urban trees
(2023)This thesis investigates the benefits and options for replacing declining urban ash trees, as well as the value-added potential of urban trees more broadly. The study aims to provide insights into the selection of suitable ... -
Modeling the impact of hemlock woolly adelgid under several climate change scenarios
(2023)The hemlock woolly adelgid (Adelges tsugae), or HWA, is a species of insect invasive to eastern North America that has caused significant mortality amongst its hemlock (Tsuga spp.) hosts. Survivorship and subsequent ... -
The association of rat prevalence and composting in Thunder Bay’s urban neighbourhoods
(2023)Landfilling is the most common municipal solid and urban organic waste disposal method in North America and comes with numerous negative environmental side effects. Encouraging greater participation in community composting ... -
Monitoring and access management of resource roads with instrumentation
(2023)Forest transportation operations are facing challenges such as having larger road networks to manage because of dispersed harvest patterns, climate changes forcing more hauling to take place under wet road conditions, ... -
Evaluation of Canada’s biomass policy in comparison to its Nordic counterparts
(2023)The transition towards renewable energy sources is considered one of the main mitigation measures combating the effects of climate change. The use of renewable energy, particularly those derived from forest biomass, is ... -
Comparison of Picea mariana, Abies balsamea, Betula papyrifera, Populus tremuloides for the production of wood pellets
(2023)Scientists and international organisations agree that wood pellets are a type of biofuel that is better for the environment than fossil fuels. Wood pellets are produced from the residues in sawmills, ground logs and is ... -
Using Canadian migration monitoring network data to assess population changes in Canada Warbler (Cardellina canadensis)
(2023)The Canada Warbler (Cardellina canadensis) has been listed since 2010 as Threatened according to the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) due to significant and long-term declines in the ... -
Triad zoning in northern Ontario and woodland caribou conservation: a critical review
(2023)Woodland caribou in Ontario are threatened, posing a conflict between habitat and timber supply for forest areas. The current management practices with Dynamic Caribou Habitat Schedules (DCHS) address long-term habitat ... -
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, ... -
Integrated resource management options for the jack pine budworm (Choristoneura pinus pinus) outbreak around Pikangikum First Nation
(2023)The outbreak of jack pine budworm (Choristoneura pinus pinus) on the Whitefeather Forest was examined to identify a correlation between the large fires and the outbreak. Maps and literature regarding both disturbances were ... -
Disconnect between Indigenous traditional connection with water due to water insecurity
(2023)People indigenous to what is now Northern Ontario have always had a traditional connection and relationship with water. In recent year, that relationship has been put through many obstacles amounting to water insecurity. ... -
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 ... -
Opportunities for Indigenous fire stewardship within Ontario’s policy framework
(2023)Indigenous people have used fire as a tool for thousands of years for resource management, community protection, and cultural purposes. The criminalization of the practice during colonization in combination with a history ... -
The potential uses of virus-infected symbionts to improve drought and heat stress in trees for improvement, climate change resilience, and restoration
(2023)With the rapid changes occurring to the climate of the boreal forest, many populations of trees are facing increased stresses and seeing lower productivity and survival. Conventional tree improvement programs take decades ... -
Tracking stand-level responses (mortality and recovery) in jack pine (Pinus banksiana Lamb.)- dominated stands following the recent jack pine budworm (Choristoneura pinus pinus F.) infestation across northwestern Ontario
(2023)This study investigates the stand-level responses (mortality and recovery) in jack pine-dominated forests following a recent infestation of the jack pine budworm across northwestern Ontario. The aim is to understand the ... -
Evaluating the effects of biomass harvesting on soil nutrient availability, foliar nutrition, and seedling growth in third-growth black spruce plantations in northwestern Ontario
(2023)Residual forest biomass is a viable feedstock that can be used in the bioenergy stream. There remains, however, a concern that excessive removal of forest biomass may have negative impacts on forest biodiversity, ...
