Action Plan for the Bluenose-East Caribou Herd
Resource
A 56-page action plan for the Bluenose-east herd prepared by the wildlife management boards with stewardship responsibilities for barren-ground caribou and their habitat in the Northwest Territories...
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
Decision-support Tools to Assess Cumulative Effects on the Cape Bathurst, Tuktoyaktuk Peninsula, Bluenose-West, and Bluenose-East Herds of Barren-ground Caribou – Project Summary Report
Resource
This report summarizes a project whose purpose was to collaboratively develop decision-support tools that will help northern decision-makers review, explore, and learn about the cumulative effects of...
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.
Does Dust from Arctic Mines Affect Caribou Forage?
Resource
A 2017 paper assessing the impacts of dust from a mining haul road in the NWT on vegetation used by caribou. The paper concluded that dust from the road negatively affected the vegetation within a...
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.
Reasons for Decision Final Report, Part B - Bluenose-East Caribou Herd
Resource
Serious conservation concern exists for the Bluenose-East caribou herd and additional management actions are vital for herd recovery. The first report, Part A, dealt with the proposed harvest...
Reasons for Decisions Related to a Joint Proposal for Dìga (Wolf) Management in Wek’èezhìı
Resource
A 109-page document on the reasons for decision of the Wek’èezhìı Renewable Resources Board regarding wolf management in the region.
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...
Tǫdzı (Boreal Caribou) and the State of Their Habitat
Resource
This report considers Tłı̨chǫ knowledge of the relationships that tǫdzı (boreal caribou) have with their habitat, including human and other-than human beings.
