The Technical Efficiency of Wildfire Suppression in Alberta, Canada: A Stochastic Frontier Analysis
DownloadFall 2021
Wildfire management agencies are increasingly interested in the efficiency of wildfire suppression as they work to protect human lives and communities from wildfire damages under constrained management budgets. In Alberta, climate change is expected to increase the length of the wildfire season...

Species invasions are increasing worldwide and are impacting populations, communities, and ecosystems. Non-native species that are ecosystem engineers, such as earthworms, may be particularly likely to have large impacts due to their ability to modify both biological and physical characteristics...

An evaluation of hitchhiker seedlings with native boreal species as a revegetation tool of industrially disturbed sites in Alberta, Canada
DownloadSpring 2020
Herbaceous forbs hitchhiked, or co-grown, with a woody species, is a solution to establish both native woody and herbaceous species at recently disturbed sites. The broad study objectives were to (1) assess the growth of fireweed hitchhiked with three deciduous woody species and one conifer over...

Biomass burning, from wildfires to cooking stoves, is a major contributor to atmospheric pollution on a global scale, affecting the quality of the air we breathe. Emissions from biomass burning are both health and climate affecting, and vary considerably in composition depending on how the fuel...

Community ecology of ants (Hymenoptera: Formicidae) in the central sand hills of Alberta, and a key to the ants of Alberta.
DownloadFall 2012
In this study I examined ant biodiversity in Alberta. Over a two-year period, 41,791 ants were captured in pitfall traps on five sand hills in central Alberta and one adjacent aspen parkland community. Using additional collections, I produced a key to the 92 species of ants known from Alberta,...

Composition and structure of spider assemblages in layers of the mixedwood boreal forest after variable retention harvest
DownloadFall 2011
Natural disturbances are important drivers of ecosystem change in the boreal forest and new approaches to sustainable forest management draw on natural disturbance patterns as a template for harvesting. The main premise for such approach is that species have evolved and adapted to stand-replacing...

Conservation and ecology of bryophytes in partially harvested boreal mixed-wood forests of west-central Canada
DownloadFall 2010
This thesis examined the efficacy of residual forest structure for the preservation and recovery of bryophytes five to six years after partial canopy harvest in boreal mixed-wood forests of northwestern Alberta, Canada. Bryophytes were sampled in two forest types that differed in pre-harvest...

The Canadian boreal forest is vital breeding habitat for North American songbirds. Extensive anthropogenic disturbances within this biome are therefore of conservation concern. Using unharvested stands as controls, I examined the effects of variable retention management (VRM) relative to...

Achieving forest recovery on previously forested well sites in northern Alberta is an on-going challenge for the oil and gas industry. Thirty-three experimental oil sands exploration (OSE) sites were constructed and reclaimed between 2004 and 2006 in northeastern Alberta. Our goal was to...

Spotting in the context of wildland fire refers to the creation of new fires, downwind from an existing fire front, where the new fires result due to the launch, and subsequent fuel bed ignition upon landing, of burning plant ma- terial released from the main front. We will present a new...
