“…However, deterioration in cover performance and even failure can be caused by increased soil permeability resulting from (i) the formation of shrinkage cracks and (ii) macropores associated with root channels or (iii) ant and termite galleries (Taylor et al, 2003) or (iv) burrowing macrofauna such as earthworms (Edwards et al, 1990;Frouz and Kuraz, 2013). While the importance of the first two causes has been accepted by soil scientists (e.g.…”

“…Some ant species bring soil material from deep soil horizons to the surface (Folgarait, 1998) or damage geotextiles, which can have negative impacts on the functionality of compacted barrier layers through the creation of preferential flow paths (Manassero et al, 2013;O'Kane Consultants Inc., 2003). Later during ecosystem rehabilitation, burrowing macrofauna such as earthworms affect the soil structure and profile characteristics in a similar manner by modifying the pore and aggregate size distribution, the soil bulk density, and soil organic matter, eventually affecting the soil water-holding capacity and infiltration rates (Blouin et al, 2013;Jouquet et al, 2014;Frouz and Kuraz, 2013). The qualitative and quantitative impact of macrofauna on hydrological variables (e.g.…”

“…Iridomyrmex species in Australia) build underground galleries, thereby initiating changes in soil properties (Lee and Foster, 1991). This macrofauna alters the local soil structure and profile characteristics (Jones et al, 1994;De Bruyn and Conacher, 1994); influence soil aggregate stability (Cammeraat and Risch, 2008;Lavelle et al, 2006), water infiltration and mechanical strength (Eldridge, 1994;Frouz and Kuraz, 2013); and increase the field capacity through the formation of holo-organic and organomineral aggregates (Frouz and Kuraz, 2013). That is, soil macrofauna introduces or increases heterogeneity of soil properties.…”

“…Through successive rainfall events, the loss of stored soil water through evapotranspiration decreases net percolation through the soil (Hauser et al, 2001;Rock, 2010) and reduces surface runoff and erosion. Regardless of the rehabilitation design, the soil macrofauna is particularly important in this initial stage of rehabilitation (Frouz and Kuraz, 2013), due to their rapid recolonisation, particularly by generalist taxa that have long-distance dispersal strategies. For example, the typical dispersal strategy for many ant species is by nuptial flights (Peeters and Molet, 2009), where copulation occurs in the air after specific climatic cues and queens fly from 100 m to 10 km from their originating nest to find suitable habitat before dropping their wings and establishing a new nest (Hölldobler and Wilson, 1990).…”

Abstract. Recolonisation of soil by macrofauna (especially ants, termites and earthworms) in rehabilitated open-cut mine sites is inevitable and, in terms of habitat restoration and function, typically of great value. In these highly disturbed landscapes, soil invertebrates play a major role in soil development (macropore configuration, nutrient cycling, bioturbation, etc.) and can influence hydrological processes such as infiltration, seepage, runoff generation and soil erosion. Understanding and quantifying these ecosystem processes is important in rehabilitation design, establishment and subsequent management to ensure progress to the desired end goal, especially in waste cover systems designed to prevent water reaching and transporting underlying hazardous waste materials. However, the soil macrofauna is typically overlooked during hydrological modelling, possibly due to uncertainties on the extent of their influence, which can lead to failure of waste cover systems or rehabilitation activities. We propose that scientific experiments under controlled conditions and field trials on post-mining lands are required to quantify (i) macrofauna-soil structure interactions, (ii) functional dynamics of macrofauna taxa, and (iii) their effects on macrofauna and soil development over time. Such knowledge would provide crucial information for soil water models, which would increase confidence in mine waste cover design recommendations and eventually lead to higher likelihood of rehabilitation success of open-cut mining land.

Water regime of reclaimed and unreclaimed post‐mining sites

et al. 2017

View full text Add to dashboard Cite

Water regime, throughfall, stemflow, soil water storage, subsurface runoff, and meteorological parameters were studied during 2 years (2011–2012) in 2 reclaimed and 2 unreclaimed post‐mining sites near Sokolov (Czech Republic). All sites were 25–35 years old, covered by woody vegetation, and developed on the same overburden consisting of tertiary clays. Interception of water by vegetation was about one third of precipitation in both reclaimed and unreclaimed sites; stemflow also did not differ significantly between sites and represented less than 10% of interception. Both reclaimed and unreclaimed sites have stable amount of soil water in the soil profile independent of precipitation, but water storage in reclaimed sites was significantly higher. The results suggest that after 25–35 years, there is no major difference in water budget of reclaimed and unreclaimed sites that develop by unassisted natural succession.

Effects of Soil Development Time and Litter Quality on Soil Carbon Sequestration: Assessing Soil Carbon Saturation with a Field Transplant Experiment along a Post‐mining Chronosequence

In previous studies, the rate of soil carbon (C) sequestration decreased with increasing age of post‐mining soils. It was also shown to depend on plant biomass and earthworm bioturbation. Here, a soil transplant experiment was used to determine whether this decrease is caused by soil C saturation or other factors (such as bioturbation and litter input). Soils collected on 15‐, 25‐ and 50‐year‐old successional sites, dominated by willow (Salix caprea L.) and birch (Betula pendula Roth), and on a 50‐year‐old site reclaimed by the planting of alder (Alnus glutinosa L.) were placed in plastic boxes that were accessible to soil macrofauna. The boxes were buried in the 50‐year‐old reclaimed site and supplemented with either alder litter or successional (willow and birch) litter. Soil C content and soil C fractions (hot water C, particulate organic C, particulate organic C bound in aggregates and C bound to mineral soil) were studied. After 1 year, the C content increased by 2–5%, but there was no effect of soil source or litter type. For all C fractions, the relationships between change in C content and initial C content were described by bell‐shaped curves. Easily available C fractions were saturated earlier than more recalcitrant fractions. Despite these saturation tendencies in individual soil organic matter pools, the soil was evidently far from saturation after 50 years of soil development. The decrease in C sequestration with soil age previously observed for this soil was probably caused by a decrease in litter input rather than by C saturation.
