The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

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...

The loss of mature forest habitat from forest harvesting represents a substantial threat to the diversity of nocturnal boreal forest moth assemblages. In this study, I used spatial patterns of species diversity to quantify the effects of aggregated green tree retention harvesting on the diversity...

Exotic species of earthworms are invading North American forests, where native earthworms were extirpated by the last glaciation. The invasion of these ecosystem engineers can alter soil organic matter (SOM) dynamics, carbon (C) persistence, and ecosystem functioning. While the topic has been...

This study quantified environmental parameters to develop reclamation strategies for phosphogypsum stacks. Research was conducted on phosphogypsum stack experimental plots established in 2006 (6 soil cap depths, 5 vegetation treatments), and soil capped slopes seeded in 1998. Significant root...

Contamination of land, water, and air is a widespread concern often associated with anthropogenic activities. Remediation of contaminated sites is necessary to minimize negative impacts on human health and the environment and allow for safe, productive use of land. Although contaminated sites...

This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...

Brunisolic soils developed on coarse textured (sandy loam to sand) deposits comprise a significant portion of the land currently being disturbed by surface mining in the Athabasca Oil Sands Region of Alberta, Canada. The goals of this study were to determine (i) how the physical properties of...

A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Prior to mining oil sands, soil is salvaged for reclamation and forest stands are harvested for their merchantable timber. Harvest operations leave large amounts of residual woody debris, which has been historically burned or mulched. Woody debris has significant ecological effects and can be...
