“…Surface integrity, a measure of the stability of the soil surface and expressed as the cover of uneroded soil surface, would be expected to increase with increasing age of rehabilitation, in line with studies of open‐cut coal mines (Li et al, 2020). However, despite the upward trend, we failed to detect significant increases in integrity with rehabilitation (Figure S8.3).…”

1. Human-induced disturbance has substantially influenced the structure and function of terrestrial ecosystems globally. However, the extent to which multiple ecosystem functions (multifunctionality) recover following anthropogenic disturbance (ecosystem recovery) remains poorly understood.2. We report on the first study examining the temporal dynamics in recovery of multifunctionality from 3 to 12 years after the commencement of rehabilitation following mining-induced disturbance, and relate this information to changes in biota. We examined changes in 57 biotic (plants, microbial) and functional (soil) attributes associated with biodiversity and ecosystem services at four open-cut coal mines in eastern Australia. Increasing time since commencement of rehabilitation was associated withincreases in overall multifunctionality, soil microbial abundance, plant productivity, plant structure and soil stability, but not nutrient cycling, soil carbon sequestration nor soil nutrients. However, the temporal responses of individual ecosystem properties varied widely, from strongly positive (e.g. litter cover, fine and coarse frass, seed biomass, microbial and fungal biomass) to strongly negative (groundstorey foliage cover). We also show that sites with more developed biota tended to have greater ecosystem multifunctionality. Moreover, recovery of plant litter was closely associated with recovery of most microbial components, soil integrity and soil respiration. Overall, however, rehabilitated | 1633

“…Therefore, monitoring the status of key soil attributes after reclamation and over time is essential for gaining insights into soil development and land restoration following reclamation (Ngugi et al, 2018;Shrestha & Lal, 2011). However, only few studies have addressed this issue (Hüblová & Frouz, 2021;Li et al, 2020;Yuan et al, 2021) and even fewer have focused on the existing ecological networks between soil microbial communities (SMCs) after land reclamation in mining areas (Li et al, 2021;Ma et al, 2020).…”

Understanding the interactions among soil microbial species and how they respond to land reclamation is essential to evaluate the success of ecological restoration actions in disturbed mine soil. In this study, we strived to reveal the interactions among soil bacterial communities along the reclamation timeline of a coal mine in Zoucheng, China. To do so, we investigated changes in the composition of soil bacterial over time and constructed molecular ecological networks (i.e., microbial network) following mining soil reclamation into agricultural land. The relationships between microbial networks and selected soil attributes (i.e., soil pH, electric conductivity, organic matter, soil nutrients and enzymatic activities) were also analyzed. The results showed that the composition of soil bacteria changed significantly along the reclamation timeline. The microbial network profile revealed that Acidobacteria, Planctomycetes and Proteobacteria were the key microbial populations. Soil pH, soil organic matter content, soil dehydrogenase and urease activities were significantly correlated (0.001 ≤ p < 0.05) with the microbial network structure, suggesting that the microbial networks found influenced the provision of relevant soil ecological functions after reclamation. The variation in complexity of the microbial networks along the reclamation timeline revealed that microbial development was promoted by the shift in land use from mining into agriculture. Overall, our findings shed light on how soil microbial communities and networks change following mine reclamation into agricultural land. The results presented herein will undoubtedly aid in the establishment of success indicators of ecological restoration activities in disturbed mining soil.

“…Singh and Singh (2006) have reported that using native tree species to repair damaged coal mines may aid the development of a self‐sustaining ecosystem in the short term. Li et al (2020) have reported that phytoremediation continuously increases soil nutrients and ecological stability. Vegetation restoration using certain woody species and vegetation can facilitate soil self‐sustainment by rectifying nutrient levels and by facilitating the accumulation of nutrients to achieve sustainable development of the degraded land (Cui et al, 2019; Dowarah et al, 2009).…”

Repair of damaged areas in open-pit (opencast) coal mines has emerged as an important environmental concern. Our research investigated the mechanism by which different ecological restoration methods affected soil nematode communities in damaged areas of desert steppe coal mines. Using high-throughput sequencing technology, nematode community composition, diversity, and function were analyzed to determine the response of nematodes to different ecological restoration methods in damaged areas of coal mines. For slope rehabilitation, vegetation blanket restoration exhibited more favorable effects than those exhibited by vegetation bag restoration and natural restoration. For rehabilitation of the platform area under the slope, the diversity of soil nematodes and the soil fauna analysis under alien soil restoration conditions were performed and exhibited similar characteristics to those of the native vegetation. Findings based on Linear discriminant analysis Effect Size (LEfSe) multi-level discriminant analysis and determination of shared genera suggest that Paraphelenchus, Cervidellus, Panagrolaimus, Microdorylaimus, Cephalobus, and Ecumenicus may be the key genera of soil nematodes in the damaged ecosystem of open-pit coal mines in the desert steppe. We found that reasonable water and fertilizer management in slope restoration and under-slope platform area restoration may play a key role in the restoration of damaged ecosystems in open-pit coal mines. We comprehensively analyzed the response of soil nematode communities and their functions to different ecological restoration methods, and provided a reference for evaluating the quality of underground ecosystem restoration of damaged areas in abandoned desert steppe open-pit coal mines.
