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
Biogeochemical Response to Vegetation and Hydrologic Change in an Alaskan Boreal Fen Ecosystem
Resource
Boreal peatlands store approximately one third of the earth’s terrestrial carbon, locked away in currently waterlogged and frozen conditions. Peatlands of boreal and arctic ecosystems are affected...
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
Constructed Wetland Pilot Project at the Strachan Gas Plant
Resource
A pilot scale constructed wetland was built at the Strachan Gas Plant to evaluate its ability to treat dissolved phase hydrocarbons in groundwater. The overall objective was to assess the feasibility...
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.
Disturbance Zones of Influence on Boreal Songbird Communities in Northeastern Alberta
Resource
Canada’s boreal forest is important habitat for many North American birds, which play a vital role in the health of forests, and provide ecosystem services. Expanding human development in northern...
Linear Features, Forestry and Wolf Predation of Caribou and Other Prey in West Central Alberta
Resource
The primary goal of this research was to determine how human activities affect caribou population dynamics through modification of predator‐prey relationships. This knowledge can then be used to...
Peat Loss Collocates with a Threshold in Plant–Mycorrhizal Associations in Drained Peatlands Encroached by Trees
Resource
Drainage-induced encroachment by trees may have major effects on the carbon balance of northern peatlands, and responses of microbial communities are likely to play a central mechanistic role. We...
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
Review of Revegetation Practices for Oil and Gas Disturbances in Western Canada
Resource
Various methods have been developed and used to revegetate sites disturbed by oil and gas activities in Western Canada. Considerable information describing these methods and their effectiveness exists...
Scaling Up the Role of Predation in Caribou Declines in West-Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges). 2012 AUPRF project status update
Resource
Avoidance by caribou and increased wolf predation risk in disturbed areas indicate functional habitat loss for caribou, yet these patterns alone do not necessarily imply a demographic impact. Spatial...
Scaling Up the Role of Predation in Caribou Declines in West‐Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges). Interim Report
Resource
Our primary goal is to address the relative contributions of forestry and oil and gas production to the decline of caribou populations. This knowledge can then be used to develop appropriate...
Scaling Up the Role of Predation in Caribou Declines in West-Central Alberta (Redwillow, Narraway, Redrock Prairie Creek, A la Pêche and Little Smoky Ranges)
Resource
Anthropogenic disturbances contribute to the way animals perceive and respond to their environment. These multiple disturbances can additionally act in non-independent ways to shape an animal’s...
