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.
Caribou (Rangifer tarandus) and Inuit Nutrition Security in Canada
Project
Organization:
The objective of this study was to examine food and nutrition security in relation to wildlife population and management status across Inuit Nunangat (the Inuit homeland, consisting of four regions...
Caribou (Rangifer tarandus) and Inuit Nutrition Security in Canada
Resource
A 2018 academic paper examining the relationship between Inuit nutrition and caribou. It found that “Caribou was the top dietary source of protein in Nunavut (up to 35% of total intake) and the ISR...
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.
Finding Lichen for Caribou
Resource
A storymap website that explains the importance of lichen as a food source for caribou and the first steps of a project for mapping lichen undertaken by Natural Resources Canada's Canada Centre for...
Historical Landscape Use of Migratory Caribou: New Insights From Old Antlers
Resource
Accumulations of shed caribou antlers ( Rangifer tarandus) are valuable resources for expanding the temporal scope with which we evaluate seasonal landscape use of herds. Female caribou shed their...

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
Potential Impact of Restricted Caribou (Rangifer tarandus) Consumption on Anemia Prevalence Among Inuit Adults in Northern Canada
Resource
Abstract Background Caribou ( Rangifer tarandus) is the top dietary source of iron and several micronutrients necessary for red blood cell production (erythropoiesis) in the contemporary diet of Inuit...
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.
The Third Generation of Pan-Canadian Wetland Map at 10 m Resolution Using Multisource Earth Observation Data on Cloud Computing Platform
Resource
Development of the Canadian Wetland Inventory Map (CWIM) has thus far proceeded over two generations, reporting the extent and location of bog, fen, swamp, marsh, and water wetlands across the country...
