Benefits of Fertilization for White Spruce and Lodgepole Pine Trees Depend on the Reclamation Substrate – Overburden vs Tailings Sand
Resource
Nitrogen and complete fertilizer applications improved growth of white spruce on overburden sites. Fertilization did not, however, have an effect on lodgepole pine growth on tailings sand sites
Boreal Trees Can Grow on Saline Sites – Implications for Reclamation Success on Saline Soils
Resource
Both aspen and spruce grew on sites with very high salinity and pH deeper in the soil profile (i.e., 40-100cm), so long as surface soils were not highly saline and had adequate moisture and nutrients.
Coarse Woody Debris Increases Microbial Functional Diversity in Reclaimed Soils
Resource
Forest floor mineral soil mix had significantly greater soil microbial functional diversity than peat mineral soil mix. CWD increased microbial biomass and microbial functional diversity in both soil
Deeper Soil Salvaging Depths Produce Greater Cover of Native Plants than Shallow Salvage Depths on a Reclaimed Coal Mine Site
Resource
The deeper soil salvage depth (40 cm) was better than the shallow salvage depth (15 cm) at establishing a forest understory plant community characteristic of the boreal forest.
Large Stocks of Peatland Carbon and Nitrogen are Vulnerable to Permafrost Thaw
Resource
Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine...
Near-surface Controls on Peatland Hydrology: Implications for Rapid Disturbance Adaptation and Enhanced Resilience to Disturbance
Resource
Northern peatlands faced compounding disturbances that transformed such critical ecosystems from long-term carbon sinks into carbon sources. Considerable investment is therefore directed for restoring...
Plow-in Pipeline Construction Improves Recovery of Rough Fescue Grassland
Resource
Plow-in pipeline approach resulted in a fescue-bluegrass vegetation community that had the best rough fescue recovery and greatest similarity to undisturbed natural grassland
Prioritization can Improve Cost Effectiveness of Seismic Line Restoration
Resource
Upland mesic sites showed a relatively strong ability to regenerate on their own (passive restoration), while lowland (bogs and fens) and upland dry sites were slow to recover.
Protecting Forest Floor in Place Rather than Stripping it Off is a Better Strategy to Regenerated Temporary Drilling Pads
Resource
Where forest floor was protected from disturbance, there were approximately 10 times as many aspen sprouts that were at least 3 times as tall as sprouts in the area where floor was stripped & replaced
Rat Root Plants May Not be Suitable for Reclaiming Oil Sands Tailing Ponds
Resource
This study tested the ability of rat root to grow in a high pH/high salinity environment, similar to that of a constructed oil sands tailings pond wetland.
Reconstructed Soils in Alberta Oil Sands Limit Fine Root Growth of Trees
Resource
Tailings sand sites: fine root biomass decreased with depth and proximity to the textural interface. Overburden sites: fine root biomass decreased abruptly at the textural interface and EC increased
Soil Salvage Depth is Key to Aspen Root Fragment Survival and Sucker Regeneration in Forest Reclamation
Resource
Aspen sucker production from root fragments was 3X higher at salvage/placement depth of 40 cm compared to 15 cm. Successful suckering occurred in root fragments with little damage in upper 20 cm soil
Temporary Drilling Pads From Oil Sands Exploration Require Microtopography for Restoration
Resource
Differences in microtopography were associated with differences in plant species richness and composition between OSE pads and the undisturbed sites.
