Transpiration Response of Residual Lodgepole Pine After Partial-cut and Strip-shelterwood Harvesting in Alberta's Southern Rocky Mountains
DownloadFall 2019
Forest harvesting reduces forest canopy cover which can reduce evapotranspiration and affect the hydrologic regime of watersheds. Prior research has shown while transpiration is reduced by the removal of trees, it can also affect soil moisture and meteorological variables (e.g....

Seeing the forest for the soil: topographic controls on soil carbon dynamics in the boreal mixedwood forest
DownloadFall 2018
Boreal forest soils store an estimated 272 Pg of carbon. Due to a high degree of spatial heterogeneity, there is a wide range in carbon stores in this ecosystem. Changes in topography and forest structure are important to carbon distribution, influencing the soil microclimate and the chemical...

Identifying understory diversity and resilience patterns with the depth-to-water index in boreal mixedwood forests
DownloadFall 2017
For the purpose of informing biodiversity conservation efforts in managed landscapes, we explored whether and how understory plant communities (abundance, diversity, composition) were related to a topographic moisture index, called depth-to-water, in the boreal mixedwood forests of northwestern...

Impacts of clear-cut harvesting on carabid beetle (Coleoptera: Carabidae) assemblages of aspen dominated forests in central Alberta
DownloadFall 2016
Disturbances, both natural and those related to human activity, reset succession in boreal ecosystems, and affect forest biodiversity. The link between forest harvesting and biodiversity is of considerable conservation concern. In this thesis, I investigate the impacts of clear-cut harvesting on...

Fall 2015
Site index is widely used as a measure of forest site productivity, and is an essential input into growth and yield models forecasting forest stand development. However, accurate estimates of site index are frequently difficult or even impossible to obtain, particularly in the boreal mixedwoods...

Natural variation and short-term impact of aspen harvesting on surface stream chemistry in the Boreal Plains
DownloadSpring 2011
This thesis describes the natural variation and influence of aspen harvesting on stream chemical concentration and flow-weighted export from catchments typical of the Western Boreal Plain, Alberta, Canada. The catchment stream discharge and stream chemical concentrations presented are taken from...

Interactions between the forest tent caterpillar (Malacosoma disstria Hubner) and its natural enemies: the effects of forest composition and implications for outbreak spread
DownloadFall 2011
Forest tent caterpillar (Malacosoma disstria Hübner; FTC), a major defoliator of aspen trees, occupies both aspen and mixedwood forest stands in Alberta’s boreal forest. Forest stand composition could influence the spatial pattern of FTC outbreaks if mortality from natural enemies differs...

Gastropod diversity in the boreal mixedwood forest of northern Alberta - variation among forest types and response to partial harvesting
DownloadFall 2010
Terrestrial gastropods are important decomposers, herbivores, and prey items in forest systems and constitute a poorly understood element of forest biodiversity in Canada. I studied gastropod assemblages in relation to forest cover type and in response to variable retention harvesting in the...
