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...

Caners, Richard T., Lieffers, Victor J., Ge, Hangfei
Winter exploration of oil sands deposits underlying wooded fens mostly eliminates the hummock-hollow topography on drilling pads and the ice roads leading to them, after their abandonment in spring. Recovery of black spruce (Picea mariana (P. Mill.) B.S.P.) and tamarack (Larix laricina (Du Roi)...

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...
