Land-use Planning Following Resource Extraction – Lessons from Grizzly Bears at Reclaimed and Active Open Pit Mines
Resource
Following closure, access management on designated trails will reduce risk of conflicts. Imposing access restrictions, preserving undisturbed habitat patches and restoring original vegetation
Large Scale Mapping of Soil Organic Carbon Concentration with 3D Machine Learning and Satellite Observations
Resource
Canada has extensive forests and peatlands that play key roles in global carbon cycle. Canadian soils and peatlands are assumed to store approximately 20% of the world’s soil carbon stock. However...
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...
Large-scale Probabilistic Identification of Boreal Peatlands Using Google Earth Engine, Open-access Satellite Data, and Machine Learning
Resource
The resulting peatland occurrence model shows an accuracy of 87% compared to our validation data set. Differentiating peatlands from mineral wetlands achieved an accuracy of 69%.
Leveraging Genomics Tools to Explore Relationships Between Agriculture, Biodiversity and Waterfowl Productivity in Prairie Wetlands
Resource
Environmental genomics is a research method that sequences DNA from samples collected from the environment (e.g. wetlands, water, soil, organisms, etc.). This method can accelerate species...
Lichens: A Limit to Peat Growth?
Resource
The fruticose lichens Cladina stellaris and Cladina rangiferina, form thick mats that can cover large areas of northern peatlands (above c. 50° latitude), including the extensive peatlands of the...
Limited Impacts of Extensive Human Land Use on Dominance, Specialization, and Biotic Homogenization in Boreal Plant Communities
Resource
Rank species occupancy curves revealed high species dominance regardless of disturbance: within any disturbance class a few species occupied nearly every site and most species were found in a low...
Long Term Prediction of Vegetation Performance on Mined Sands
Resource
This project on the "Long Term Prediction of Vegetation Performance On Mined Sands" (V.E.6.1) was undertaken to provide management with answers on the predictive ability to maintain different kinds of...

Low-impact Line Construction Retains and Speeds Recovery of Trees on Seismic Lines in Forested Peatlands
Resource
Abstract Seismic lines are linear features created by the oil and gas industry for energy exploration. Though individually narrow, collectively seismic lines are a pervasive management challenge...
Low-impact Line Construction Retains and Speeds Recovery of Trees on Seismic Lines in Forested Peatlands
Resource
Seismic lines, linear features originating from the oil and gas industry for energy exploration, pose a substantial management challenge due to their collective impact on biogeochemical cycles, plant...

Event Date and Time
March 14th, 2024 at 12:00pm MST to March 14th, 2024 at 1:30pm MST
Organization
Humans impact everything, including our soil. We remove, mix and compact soil horizons. We add amendments, including waste materials, to replace soil or improve its health. Soils that that have been...

Managing Wolves (Canis Lupus) to Recover Threatened Woodland Caribou (Rangifer Tarandus Caribou) in Alberta
Resource
Across Canada, woodland caribou ( Rangifer tarandus caribou (Gmelin, 1788)) populations are declining because of human-induced changes to food webs that are resulting in apparent competition-induced...
