Article
Full-text available
In Canada, low-grade ore mines generate large amounts of mineral waste, such as mine tailings. To control erosion of the fine-grained tailings particles as quickly as possible, it is common practice for the mining industry to revegetate the mine tailings with agronomic herbaceous plants. However, it is unclear whether this practice is consequential...
Article
One of the main environmental risks related to the surface storage of reactive mine tailings is acid mine drainage (AMD). AMD generation is often managed by limiting oxygen access to the reactive tailings. To do so, engineered cover systems such as covers with a capillary barrier effect (CCBEs) can be used. Over time, plants may colonize CCBE mater...
Article
Organic covers are increasingly used to control the generation of contaminated mine drainage from tailings impoundment facilities. Their efficiency in controlling the mobility of contaminants in the underlying tailings depends on their biogeochemical and hydrogeological properties. In the present study, fibric peat, an easily accessible material at...
Article
Full-text available
Abandoned unrestored mines are an important environmental concern as they typically remain unvegetated for decades, exposing vast amounts of mine waste to erosion. Several factors limit the revegetation of these sites, including extreme abiotic and unfavorable biotic conditions. However, some pioneer tree species having high levels of genetic diver...

Article
It is well known that soil physico-chemical conditions and the nature of organic matter have important effects on soil micro-arthropod communities, including collembolans. However, mechanisms by which the physical or chemical quality of litter influence collembolan communities remain unclear. Plant secondary metabolites are partially released in so...
Article
Covers with capillary barrier effects (CCBE) are multilayered oxygen barrier covers used in humid climates to reclaim reactive mine tailings and limit the generation of acid mine drainage. Once constructed, CCBEs are colonized by surrounding plants. Roots modify water storage and respire oxygen. The performance of CCBEs could evolve over time due t...
Article
Refractory ores, in which gold is often embedded within As-bearing and acid-generating sulfide minerals, are becoming the main gold source worldwide. These ores require an oxidizing pre-treatment, prior to cyanidation, to efficiently breakdown the sulfides and enhance gold liberation. As a result, large volumes of As-rich effluents (> 500 mg/L) are...
Article
Full-text available
In reclaimed waste rocks slopes, the soil cover spread for revegetation is prone to erosion. This soil needs to be immediately protected from soil erosion by above and belowground vegetation. The seeding of fast-growing herbaceous species used in agriculture is generally used on waste rock slopes to control erosion, but these compete with planted t...
Conference Paper
Full-text available
Mine tailings can produce acid mine drainage (AMD) when exposed to water and oxygen. Under humid climates, one of the methods used to control AMD production is the use of an oxygen barrier cover such as a cover with capillary barrier effect (CCBE). CCBEs functioning relies on maintaining a high degree of saturation in one of the cover layers called...
Article
Peat and mine drainage treatment sludge can be valorized as amendments on mine sites to stabilize gold mine tailings and reduce the potential leaching of contaminants in pore water. However, the influence of organic amendments on the mobility of metalloids and/or metals in the tailings must be validated, as the leached contaminants may vary accordi...
Article
Mine wastes create harsh recruitment conditions for forest tree seedlings, especially waste rock piles where erodible slopes are prone to drought. Plantations using fast-growing tree species can potentially accelerate the conversion of degraded mine sites into forests through facilitation of tree recruitment, while contributing to the stability of...
Article
Full-text available
Root development is important to ensure tree survival in conditions of water stress. Despite their long-recognized role, little attention has been given to their development on waste rock slopes subject to rapid drainage. This study was conducted in an open-pit gold mine in a boreal forest. Its main objective was to establish a plantation design wi...

Les résidus miniers peuvent produire du drainage minier acide (DMA) lorsqu‘ils sont exposés à l’eau et à l'oxygène. Une des méthodes utilisées pour empêcher cette production est l’installation d'une barrière à l’oxygène telle une couverture multicouche avec effet de barrière capillaire (CEBC). Les CEBC limitent la diffusion d’oxygène en maintenant...
Article
Organic amendments aided with vegetation are considered a promising prevention approach for the stabilization of metal-contaminated tailings. However, the inconsistency in the performance of different amendments and their effects on plants growth indicate that further studies are still required. To better select the appropriate organic amendments a...
Article
Full-text available
Surface metal mining produces large volumes of waste rocks. If they contain sulfide minerals, these rocks can generate a flow of acidic water from the mining site, known as acid mine drainage (AMD), which increases trace metals availability for plant roots. Adequate root development is crucial to decreasing planting stress and improving phytoremedi...
Article
Full-text available
Metal mining generates large volumes of wastes, which can contain sulphide minerals that generate acid when exposed to atmospheric conditions, providing unfavourable conditions for plant establishment. In particular, mining waste rocks are piled on tens of meters, and remain devoid of vegetation, creating a desolated anthropogenic landscape. The us...
Article
Full-text available
Tree planting can accelerate the conversion of mine sites into forests after closure, thereby decreasing environmental impacts on forested landscapes. However, few studies have investigated tree planting to reclaim metalliferous mine tailings. To mitigate the restrictions to tree growth associated with mine tailings, soils and amendments can be use...
Article
Full-text available
The seeding of agronomic graminoid species that are tolerant to the compacted and low aeration conditions associated with mine tailings allows for rapid cover of mine waste, which in turn controls erosion. These graminoids can be used as primer-species on mine tailings to improve the rooting of other plant species, which may not tolerate soil compa...
Article
Full-text available
A broad and diversified group of compounds, secondary metabolites, are known to govern species interactions in ecosystems. Recent studies have shown that secondary metabolites can also play a major role in ecosystem processes, such as plant succession or in the process of litter decomposition, by governing the interplay between plant matter and soi...
Conference Paper
The management of mine solid waste remains the most important environmental commitment for mine companies. This research project was carried out on the low sulphur waste rock of the Canadian Malartic mine, with the aim of assessing the erosion control effectiveness of different plantation designs on 33% slopes. Since the mine is located in the bore...
Article
Full-text available
Tree water uptake relies on well-developed root systems. However, mine wastes can restrict root growth, in particular metalliferous mill tailings which consist of the finely crushed ore that remains after valuable metals are removed. Thus water stress could limit plantation success in reclaimed mine lands. This study evaluates the effect of substra...
Article
Full-text available
Background and Aims Abandoned lands are increasingly used to establish fast-growing tree plantations, and are often rapidly colonized by a high density of herbaceous undergrowth. These weeds are generally removed since they compete with trees for resources, in particular soil nutrients. However, mixing herbaceous litter with the litter of planted t...
Article
Full-text available
Tree species influence the litter decomposition process by influencing litter quality and soil microclimate. Furthermore, over the long term, trees could promote soil communities that are particularly capable of degrading the litter they encounter most often. Thus, plant litter could decompose faster when placed in the habitat from which it was der...
Conference Paper
Full-text available
In forested regions, the revegetation of milled mine tailings should aim at tree establishment to decrease the environmental impacts of mining and foster social acceptability. However, tree establishment on fine grain-sized mine tailings is difficult due to physical restrictions, in particular low macroporosity and saturated hydraulic conductivity,...
Article
Full-text available
Tree planting is a useful means of integrating reclaimed mine sites into natural forested landscapes. The main objective of this study was to evaluate the effect of soil thickness and nature on the establishment and metal accumulation of trees planted in non acid-generating mine wastes under boreal conditions. Two field experiments were conducted t...

On Mediterranean calcareous soils, high fire frequency induces soil impoverishment and the development of stable Quercus coccifera garrigues. Organic amendment could increase soil fertility levels, and could alter the vegetation dynamics and the established dominance relationships. In this study, the plant cover evolution is monitored in an amended...
Article
Mediterranean soils are generally low in organic matter and have a low water holding capacity. Moreover, recurrent fires are common in Mediterranean regions and increase the deterioration of these soils. Soil properties and ecosystem resilience after fire could be improved by amendment with compost, which is a source of organic matter and nutrients...

The aim of the study was to evaluate the effects of sewage sludge compost (control, 20 kg m(-2), 40 kg m(-2)) supplied to Quercus pubescens Willd seedlings planted in a post-fire calcareous site in Provence (France). Changes in soil properties, seedling survival, growth and nutrition were monitored 7 months, 1.5 years and 2.5 years after amendment,...
Article
In Mediterranean frequently burnt areas, fire and erosion result in the decrease of soil fertility, so afforestation is a major concern. We carried out an in situ experiment of compost amendment to improve survival and growth of planted tree seedlings. One-year-tree seedlings of native species (Quercus ilex, Pinus halepensis and Pinus pinea) were p...
Article
Full-text available
In Mediterranean areas, often characterized by degraded soil due to recurrent fires and violent precipitation events, sewage sludge com- post could improve soil properties and stimulate plant succession pro- cesses. Most of the studies dealing with compost effects on soil properties only take into account the mineral horizon compartment, without st...
Article
Estimation of litter colonization by fungi, using ergosterol, an indicator of fungal biomass, is a reliable way to describe the process of leaf litter decomposition. This litter colonization by fungi is regulated both by exogenous or environmental factors, and endogenous factors, i.e. litter chemistry. In this work, we have examined the effects of...
Article
Terrestrial Mediterranean ecosystems are characterized by low water and organic matter soil content, which become worse with recurrent fires. Biosolids amendment could be a way to facilitate ecosystem resilience. Leaf litter decomposition is a vital process in the functioning of terrestrial ecosystems and can be studied through fungi and bacteria....
