“…The TT were also relatively low in nutrients and high in sodium and sulfur compared to the PMM (Table 1). The PMM's values were within the general range of PMM coversoil used for reclamation in this region (MacKenzie and Quideau 2012; Schott et al 2016;Stack et al 2020Stack et al , 2021.…”

“…Lalonde et al (2020) also noted that VMC generally increased with soil capping depth, although capping depth effects were not evident in this 16week study. In a reclamation field study using various subsoil and topsoil capping treatments above lean oil sands overburden, enhanced growth on thicker capping depths (>30 cm) was observed in the third growing season (Stack et al 2020).…”

This three-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 the 30 cm PMM cap outperforming the 10 cm PMM. 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.

“…PHCs F1-F4 in the CF tailings and F1-F3 in the CM tailings exceeded Alberta Tier 1 guidelines. PRM parameters were within the general range of coversoil used for reclamation in this region (MacKenzie and Quideau 2012; Schott et al 2016;Stack et al 2020Stack et al , 2021 and the till had a higher pH, sand content, and exchangeable Ca 2+ concentration relative to the other substrates (Table 1).…”

Growth and survival of native wetland species in shallow capped centrifuged tailings and co-mixed tailings: a meso-scale greenhouse study

et al. 2023

This three-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 three 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 survival and above-ground biomass were Salix bebbiana, Scirpus microcarpus and Carex aquatilis.

“…Most forests are distributed in water-rich regions. Although annual precipitation in most boreal forest regions is always less than 500 mm, they are not water-limited due to the high soil water-holding capacity of high soil organic matter [33] and low water loss under thermal constraint. Mesic species adopt a riskier sequence through looser stomatal regulation to maximize carbon uptake at the expense of hydraulic safety [32].…”

Vegetation and Evapotranspiration Responses to Increased Atmospheric Vapor Pressure Deficit across the Global Forest

A forest is vulnerable to drought and plays important roles in the regulation of carbon and water cycling in a terrestrial ecosystem. Atmospheric vapor pressure deficit (VPD) has been identified as an increasingly major factor in plant functioning and has been established as a main contributor to recent drought-induced plant mortality, independent of other drivers associated with climate change. However, most previous studies have focused on the effects of climate warming and CO2 enrichment on vegetation growth, without considering the effects of an increased VPD on vegetation growth and evapotranspiration (ET) in forest ecosystems. This could lead to a large uncertainty in estimating the variability in forest carbon sinks. Based on the long-term satellite data, we investigated the response of the leaf area index (LAI) and ET to the VPD via a partial correlation analysis in this study. We also examined the temporal variability in the partial coefficients within a ten-year moving window. The results showed that over 50% of the region displayed a negative partial correlation between the LAI, ET, and VPD, and those pixels were mainly concentrated in North America and the plains of Eastern Europe. Regions with a negative trend of partial correlation in both the LAI and ET are mostly located in the plains of Eastern Europe and the Siberian Plain of western Russia, while the positive trend is mainly in South America. The plains of Eastern Europe are becoming drier, which was proved by the interannual trend of the Standardized Precipitation Evapotranspiration Index (SPEI) and soil water content (SWC). Additionally, the LAI and ET in those areas exhibited a significant positive correlation with the SWC based on the moving window average. This study suggests that the role of the VPD on vegetation will become increasingly prominent in the context of future climate change for the forest ecosystem.
