“…The results showed that the soil porosity of the GFG sites was significantly higher than that of the cultivated land, which is consistent with the present findings (Ning et al, 2019). Soil organic matter of site A was 62.41% higher than site D, probably as a result of higher microbial biomass, which decomposes vegetation litter and humus on the soil surface resulting in more soil organic matter (Cui et al, 2010;Lin et al, 2011;. The total nitrogen content of site A was 58.59% higher than site D, probably as a result of nitrogen from the leaf litter entering the soil with rainwater following decomposition by microorganisms.…”

A 1-year baseline survey was conducted in north-western China to evaluate the ecological restoration quality of grain for green (GFG) using soil ciliate communities. The aims of this study were focused on analyzing the changes of soil ciliate communities in four plots (A, GFG for 15 years; B, GFG for 13 years; C, layland; D, cultivated land) for GFG environmental assessment. Simultaneously we studied the effects of vegetation communities and physical-chemical variables with GFG changes on soil ciliates. A total of 114 species of ciliates were identified among the four sample sites, representing 9 classes, 14 orders, 22 families and 37 genera. The community patterns of the soil ciliates were significantly correlated with the individual abundance of aboveground plants, soil water content, and soil porosity. The contents of total nitrogen were the main factor affecting the soil ciliate community composition. The species number, individual abundance, and diversity index of the ciliates were each in the order A>B>C>D; that is, the community composition of ciliates was complicated with the implementation of the GFG. It was shown that the succession of ciliate community shifts toward promoting the complexity with the progress of GFG. These findings demonstrate that soil ciliate communities may be used as a useful indicator to evaluate the effects of the ecological restoration quality of GFG.

“…This is probably why biodiversity hotspots need good protection from surrounding disturbances caused by human activities, such as mining. Many native plant species in Australia have developed sophisticated microbial-root acquisition and foliar N conserving mechanisms to live in infertile soil of very low levels of available N and P, such as native Banksia and Jarrah species (Lin et al 2011;Pate et al 1993) and spinifex in arid landscapes (Winkworth 1967).…”

The rehabilitation of mined landscapes has reached a significant crossroad. There are rising regulatory and community expectations and financial costs, but operational success has made very slow progress across the mining and minerals sectors. The history of rehabilitating mined landscapes is relatively short, with prescriptive approaches encouraged by the introduction of the US Surface Mining Control and Reclamation Act in 1977. During these four decades, the goalpost of closure standards has shifted from non-pollution in the 1980s, sustainable land use since 1990s, to 'resilient ecosystems', in response to the society's acceptance of climate change and uncertainties. In the meantime, operations at mine sites have been largely resorting to 'environmental engineering' (or briefly referred to as 'engineering') thinking and approaches to reconstruct and rehabilitate mined landscapes for economic and natural land uses. The continuation of 'engineering' from mining into rehabilitation is because this mindset is conducive to 'engineering' methods which are prescriptive and definitive in operational process, such as land contouring, topsoil sheeting, and seed sowing, fertilisation, drainage installation, and slope stabilisation. In contrast, the transition into 'ecological' thinking is much needed to design and create new ecosystems at an operational level. 'Ecological' methods are descriptive and characteristics of undefined operational requirements and associated risks in the short/intermediate term. In many cases, agroecosystems (e.g. pastures) have been adopted as post-mining land use of mined landscapes, such as coal mines in central Queensland. Agroecosystems at remote mine sites may not be sustainable due to high energy requirements to improve and maintain the productive capacity for economic outcomes in landscapes with inherently infertile soils and low rainfall. Nor are they 'resilient' due to the lack of ecological diversity and functional redundancy. In other cases, the goal is to restore the mined landscapes back to seemingly 'original' ecosystems, based on comparing short-term ecological features with non-disturbed 'reference sites', while disregarding the loss of regolith structure and landform diversity after mining.
