Phosphogypsum (PG), an acidic byproduct of phosphoric acid production during phosphate fertilizer manufacturing, is commonly stacked on the facilities and capped with soil at decommissioning. The research evaluated soil capping depth (0, 8, 15, 30, 46, 91 cm) effects on response of five seeded...
EFFECTS OF MICRO SITES AND AMENDMENTS ON NEAR SURFACE SOIL TEMPERATURE AND VOLUMETRIC WATER CONTENT TO ENHANCE REVEGETATIONDownload
Land reclamation requires successful germination, emergence and establishment of desired plant species. Seed and micro sites, often lacking in disturbed ecosystems, can be limiting factors for germination and plant establishment. Micro sites, or safe sites, are required to reduce or prevent soil...
Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...
Natural Recovery of Upland Boreal Forest Vegetation on a Hummocky Peat-Mineral Mix Substrate in the Athabasca Oil Sands Region, AlbertaDownload
This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...
Oil Sands Reclamation With Woody Debris Using LFH Mineral Soil Mix And Peat Mineral Soil Mix Cover Soils: Impacts On Select Soil And Vegetation PropertiesDownload
Prior to mining oil sands, soil is salvaged for reclamation and forest stands are harvested for their merchantable timber. Harvest operations leave large amounts of residual woody debris, which has been historically burned or mulched. Woody debris has significant ecological effects and can be...
Drilling fluid, also referred to as drilling mud, is used to lubricate and cool the drilling apparatus, transport drill cuttings to the surface and seal off porous geologic formations. Disposal of drilling fluid is a growing concern to the global oil and gas industry as it can require extensive...
Plant and soil biophysical properties for evaluating land reclamation in Jasper National Park, CanadaDownload
Jasper National Park has numerous disturbances in the montane and subalpine ecoregions of varying ages and causes, such as pipelines, road ways, trade waste pits and recreational activities. These disturbances are in various degrees of effective reclamation, in some cases soil conditions have...
Prairie plant species at risk in Southern Alberta: identification of critical habitat at the microsite level for Halimolobos virgata (Nutt.) O.E. Schulz and determination of set back distance between pipeline disturbance and Halimolobos virgata and Cryptantha minima Rydb.Download
Little is known about the effect disturbances such as pipelines can have on prairie plant species at risk and their critical habitat in Alberta. Halimolobos virgata appears to be a ruderal, disturbance evolved species that occupies a unique rim niche. This habitat around the rim of depressional...
Festuca hallii (plains rough fescue), a late-seral bunchgrass and long-lived perennial, is difficult to restore once disturbed. Once dominant in grasslands throughout central Alberta, F. hallii now occurs in remnants, a result of agricultural and residential development, and oil and gas...
This research determined if woody debris amendments facilitate land reclamation after oil sands mining. Specifically, it assessed if woody debris affects vegetation cover and richness, woody species survival and abundance, soil nutrients, temperature and water, microbial biomass carbon and...
