Competitive Relationships in Forest Restoration: Impact of Cover Crops and Fertilization on Tree and Understory Development
DownloadFall 2014
Initial reclamation practices affect the early development and future recovery trajectories of tree and understory species on reclamation sites. In this thesis I explored the effects of yellow sweet clover (Melilotus officinalis) as a cover crop on tree performance and competition control in...

Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...

Legacy propagule banks of salvaged topsoils are excellent sources of plant propagules for reclamation of mine sites. However, prior studies show that less than 50% of species found in original propagule banks actually establish. We hypothesize that the expression of this legacy propagule bank is...

The role of microtopography in vegetation colonization and early forest development on mine reclamation sites
DownloadSpring 2023
Microsite heterogeneity is an important variable that drives biodiversity in forests. Current forest reclamation practices often do not incorporate site heterogeneity in their practices which might pose a challenge to the reclamation goals of restoring disturbed sites to resilient and sustainable...

Spring triticale is being evaluated as a platform crop for bio-industrial products on the Canadian prairies and may require genetic modification (GM). Seed lost at harvest may persist and result in volunteer GM triticale populations in following crops that could impact co-existence with...

Integrating cultural weed management practices with herbicides is an important strategy to reduce wild oat (Avena fatua L.) populations in Alberta, Canada. The purpose of this thesis is to expand the knowledge on wild oat seed banks and seedling emergence within integrated weed management...
