This 3-year meso-scale greenhouse study used 55-gallon columns to evaluate the survival and growth of boreal wetland communities planted on centrifuge (CF) tailings and co-mixed (CM) tailings capped with different reclamation cover soil capping designs. The CF tailings were capped with a shallow layer (10 and 30 cm) of peat reclamation material (PRM) and the CM tailings were capped with a shallow layer (5 cm) of PRM above 15 or 35 cm of reclamation subsoil (till). After 3 years, plant survival and growth on CF tailings showed significant improvement with a 10 cm PRM cap compared to the uncapped tailings, and plants growing on a 30 cm PRM cap outperformed those on the 10 cm PRM cap. Plant growth on CM tailings was significantly improved with a soil cover containing 5 cm PRM and at least 15 cm till. Among the seven native wetland species included in this study, the top performing species in terms of survival and above-ground biomass were Salix bebbiana, Scirpus microcarpus, and Carex aquatilis.

This 3 year meso-scale greenhouse study used 55 gallon columns to evaluate the survival and growth of boreal upland and wetland communities on thickened tailings (TT) with 0 cm, 10 cm, and 30 cm peat mineral mix (PMM) reclamation cap. While survival was high in all treatments, the PMM cap treatments showed significant improvement in overall plant growth, cover, and above-ground biomass compared to the uncapped treatment, with growth on the 30 cm PMM cap outperforming the 10 cm PMM cap. The plant growth response was similar between the two communities and the top performing species, in terms of survival and growth, in capped TT were Cornus sericea, Populus tremuloides, Salix bebbiana, and Scirpus microcarpus.

The article discusses a study on the growth of aspen and white spruce on naturally saline areas and its significance for developing forest productivity on reclaimed saline soils. It cites the methods used in the study in the saline areas of northern Alberta, such as soil and tree sampling and basal area growth using analysis of variance (ANOVA). Results indicate growth decline in white spruce which also suggests that rooting limitation may restrict forest productivity related to salinity.

The article presents a study which assessed the appropriateness of an organic residual cover on mine tailings for the production of bioenergy crops. It mentions the importance of reclamation of mining areas for nearby communities due to related environmental and health hazards. It says that the study used paper mill biosolids to build an experimental area within closed tailings in Copper Cliff, Ontario for the winter of 2007-2008.

The article presents a study on the application of reforestation and soil reclamation techniques on five gas and oil well sites in northeastern British Columbia. It states that treatments including tillage, brush mats, and wood chip mulch and chemical analysis were conducted to the area. Results suggest that soil rehabilitation and well site construction treatments have little impact on soil nitrogen and carbon.

The article presents a study on natural and reconstructed soil phenolic profiles from Athabasca oil sand region Alberta, Canada. It states that soil samples were taken to investigate the organic matter composition between natural and reconstructed soils. Results show that the presence of vanillyl phenols, coumaryl phenols, p-hydroxy phenols, and other phenolic community are much higher in natural soils than in reconstructed soils.

The article presents a study which quantifies soil water regimes of the reclaimed upland slopes in Alberta's oil sands region. It mentions that lower slope positions have higher soil water contents than the upper slope position, wherein vegetation and soil variability may influence soil water's spatial variability. It states that soil water in the peat-mineral mix was influenced by the textural discontinuity on reclaimed slopes.

The article presents a study on the reclamation of mined areas in the Athabasca oil sands region by analyzing the soil water dynamics using unsaturated flow modeling. It mentions the importance of soil water dynamics analysis in developing adequate reclamation strategies. It states that simulation of fluxes and soil water dynamics at the water table was conducted for three scenarios of reclamation and were compared with that fluxes that were obtained from natural conditions.

The article presents a study on the evaluation of mining waste materials that are possible for use in soil reclamation at a diamond mine in Northwest Territories. The study used substrates including glacial till, gravel, and processed kimberlite, as well as amendments including salvaged topsoil, sewage sludge, and inorganic fertilizer. The results showed that salvaged topsoil provided an increase in plant density, while sewage is a good source of organic matter.

The article focuses on the history of reclamation practices and lignite coal mining in Lusatia, eastern Germany. It says that Germany is dependent on lignite processing and lignite mining industries since the 19th century and considered as the leading producer of lignite coal in the world. It offers an overview of the post-mining reclamation and techniques of lignite mining in the country. It also mentions the technical process and natural composition for constructing mine site.

The article focuses on the regulatory history of the industrial land reclamation and conversion program in Alberta. It says that land reclamation started in the province upon the Surface Reclamation Act's enactment in 1963. It mentions that the reclamation and conversion program is influenced by several factors including public expectations, science advancements, and regulatory policies. It also mentions the jurisdiction that balances environmental protection and industrial development.
