Abstract
The topsoil native seed bank is a valuable resource in post‐mining rehabilitation capable of providing a cost‐effective means for restoring plant diversity. However, the value of the native soil seed bank is affected by topsoil management practices especially long‐term stockpiling. Salvaged topsoil is usually stockpiled until mining operations are completed and landforming has been performed. This study compared the germinable soil seed bank of freshly harvested topsoil against the effects of stockpile age (stored for 1 and 3 years) and depth (top and bottom 50 cm of 2‐m‐high stockpiles). Total native seedling emergence was greater from the 1‐year‐old stockpile but was dominated by annuals including species commonly found on disturbed sites. Seedling emergence of perennial species was more than 4‐fold greater in fresh topsoil than in the 1‐year‐old stockpiles, and 2‐fold greater than the bottom 50 cm of 3‐year‐old stockpiles, with no difference in the top 50 cm of the 3‐year‐old stockpiles. Although there was no difference in total emergence between the top and bottom of stockpiled topsoil, there was greater emergence of the ecologically important Triodia grass genus from the top than bottom of 3‐year‐old stockpiles. Species composition of the seed bank in the 1‐year‐old stockpile was different to fresh topsoil and the 3‐year‐old stockpile possibly reflecting differences in species composition of vegetation present when topsoil was initially salvaged for stockpiling, confounding comparisons between years. This study demonstrates the importance of conducting soil seed bank analysis of stockpiled topsoil to be used in restoration programs.

A thorough knowledge of soil functionality is critical to successful restoration of disturbed ecosystems, and its evaluation involves the assessment of soil properties and processes as a component of a healthy ecosystem. Here, we propose a set of soil quality indicators to assess the soil status in restored soils (topsoil and waste material) and test new methods that are easy to apply, interpret, and cost-effective for the analysis of soil biological indicators in restored ecosystems. We show th...

Abstract Natural disturbances such as wildfires cause significant alterations to the structure and functioning of semi-arid ecosystems. After such disturbances, the recovery of the soil ecosystem as a whole, and more specifically the belowground microbial communities, is poorly understood. In this study, we aimed to (a) assess the short, medium and long term changes in soil physicochemical and microbiological indicators and indices after a wildfire in a semi-arid environment, (b) analyse the key...

Simultaneous environmental changes challenge biodiversity persistence and human wellbeing. The science and practice of restoration ecology, in collaboration with other disciplines, can contribute to overcoming these challenges. This endeavor requires a solid conceptual foundation based in empirical research which confronts, tests and influences theoretical developments. We review conceptual developments in restoration ecology over the last 30 years. We frame our review in the context of changing...

Topsoil is a valuable resource for revegetation of mine sites as it contains seeds of plant species indigenous to the local environment. As mine site restoration is undertaken after the completion of mining, it is a common practice to stockpile topsoil in preparation for restoration activities. While many studies have found a decrease in seedling emergence with increasing stockpile age in temperate regions around the world, a few examine the effect of stockpile age on topsoil seed bank and seedl...

Global warming is occurring more rapidly above the treeline than at lower elevations and alpine areas are predicted to experience above average warming in the future. Temperature is a primary factor in stimulating seed germination and regulating changes in seed dormancy status. Thus, plant regeneration from seed will be crucial to the persistence, migration and post disturbance recruitment of alpine plants in future climates. Here, we present the first assessment of the impact of soil warming on...

Two new troglobitic species of silverfi sh of the genus Trinemura Silvestri are described from the semi-arid Pilbara region of Western Australia. A third species is recorded but not described due to the lack of a mature male specimen. The deep subterranean habitat of these new species is developed within weathered rocks of banded iron formation. The surveyed distributions of each species appears confi ned to proximal landforms which are topographically and geologically isolated from each other. ...

A thorough understanding of the rate of depletion of ungerminated seeds in soil is necessary to understand and model the population dynamics of many plant species. To assess how edaphic conditions influence seed survival over time a long-term field study was set up. Mesh bags of seeds of 12 species were buried under 12 contrasting semi-natural and grassland habitats and retrieved at intervals over 10 years. Seed survival and viability were assessed through germination trials and chemical stainin...

With nearly two-thirds of the world's ecosystems degraded ( 1 ), the October 2010 meeting of the Conference of the Parties to the Convention on Biological Diversity (COP-10) highlighted ecological restoration as a significant opportunity for achieving global conservation goals ( 2 ). The restoration of nature, natural assets, and biodiversity is now a global business worth at least $1.6 trillion annually and likely to grow substantially ( 3 ). Although seed banks have emerged as a tool to protec...

Typical reclamation practices in the central Appalachian coal region often use compacted spoils as a topsoil replacement, and these soils are revegetated with aggressive grasses and legumes. This restoration approach results in an herbaceous-dominated landscape with limited natural succession by native flora. An alternative restoration method is to save topsoil prior to mining, stockpile it during mining, and then replace it on uncompacted spoils to “inoculate” the site with native plant species...

Surface soil reclamation is used to increase the re-establishment of native vegetation following disturbance through preservation and eventual replacement of the indigenous seed reserves. Employed widely in the mining industry, soil reclamation has had variable success in re-establishing native vegetation in arid and semi-arid regions. We tested whether variable success could be due in part to a decrease of seed reserves during the reclamation process by measuring the change in abundance of germ...

Although aboveground metrics remain the standard, restoring functional ecosystems should promote both aboveground and belowground biotic communities. Restoration using salvaged soil—removal and translocation of topsoil from areas planned for development, with subsequent deposition at degraded sites—is an alternative to traditional methods. Salvaged soil contains both seed and spore banks, which may holistically augment restoration. Salvaged soil methods may reduce non-native germination by buryi...

Abstract Mining activities have significant environmental impacts, such as the production of acid mine drainage and the typical absence of vegetation on mine tailings whose absence can facilitate the migration of metals to adjacent ecosystems. We investigated the metal and metalloid composition of plants and substrates on, and near a former gold mine site to understand elemental dynamics in such environments. A mine tailings deposit rich in Mo and As in Northwestern Quebec was studied following ...

Abstract The reforestation of the Amazon forest after mining requires the introduction of native species, such as the Brazil nut tree. However, there are incipient studies with the Brazil nut tree under these conditions. The aim of this study was to diagnose soil properties that determine the adequate growth of Brazil nut trees in bauxite mining restoration areas in the Amazon forest. Three Brazil nut tree sites in bauxite mining reforestation areas in Porto Trombetas–Oriximina (Para, Brazilian ...

Mineral tailings impoundments represent a rapidly growing land area requiring revegetation and a major challenge to restoring biodiversity in postmined environments. Topsoil covers are essential for revegetation, to mitigate the physical and hydrogeochemical obstacles presented by tailings. However, mines in arid and semiarid regions are often large scale and geographically isolated from resources and suffer a scarcity of suitable topsoil, stimulating interest in cost‐effective shallow cover sys...

Restoration of degraded arid and semi-arid land faces the challenge of reinstating vegetation communities exposed to limited and variable rainfall events that in combination with a deficit of original topsoil may exceed thresholds for seedling development. In a series of glasshouse experiments, we evaluated variation in drought responses of (i) 21 arid zone plant species from the mining intensive Pilbara region of Western Australia in an original topsoil substrate and (ii) four selected species ...

The use of native plant seeds is fundamental to large-scale rehabilitation and the re-establishment of self-sustaining ecosystems after high-impact mining activity has ceased. However, many of the biological attributes of seeds are often overlooked in large-scale rehabilitation programs. Multi-disciplinary, long-term research collaborations are required to improve seed-based mine rehabilitation. In this paper, we review the steps that BHP Western Australia Iron Ore (WAIO), a large iron ore minin...
