Revegetation of Mine Sites
Published in Bruno Bussière, Marie Guittonny, Hard Rock Mine Reclamation, 2020
Finally, whatever the selected plants for revegetation, diversity of species and genotypes is important to increase the chances of plant establishment in variable living conditions on reclamation sites and to increase resistance to stresses and diseases. Moreover, diverse planting or seeding mixtures will provide differing habitats for recolonization by a diverse flora and fauna.
Energy as a Consumptive Product

Impacts on wildlife can be mitigated with several measures. Revegetation is one of them, offering protection against wildlife habitat loss and against landslides and soil erosion. Additionally, restricting sites of human activities to the minimum required and reclaiming areas that are no longer necessary can contribute to the minimization of wildlife habitat loss.
Some physiological characteristics to estimate species potential as a mine reclamation ground cover

The planting of vegetation to stabilise soil disturbed by mining has become common practice in much of the world, and is a requirement in many countries. A primary goal of revegetation, upon which many regulations are based, is to stabilise surface materials reducing the movement of sediment into surface waters and prevent the development of erosional landforms. The visual improvement of mined landscapes is another common goal, prompting revegetation activities on both newly mined land and older mine spoils where vegetation has not developed spontaneously. The establishment of vegetation by direct seeding is an economically attractive option and the selection of herbaceous species is often based on seed cost and availability, and on the reliability of vegetation establishment. Regional ground cover mixtures are often developed by trial and error. Agronomic species are commonly used because seeds are readily available, relatively low in cost, planting dates and methods are well established, and in many cases are available as widely adapted cultivars. Seeding trials have identified species or cultivars tolerant of adverse chemistry, such as high metal concentrations of some mine spoils [1]. Identification and demonstrated success of some species for mine reclamation has led to their widespread use on regional and even global scales over the past few decades.

With the progression of science and technology, economic expansion, industrial growth, escalation of urbanization and augmentation of population, the rate of utilization of mineral resources is incessantly escalating. Mining activity caused damage to the environment because of the production of heavy metals during the process (Pavilonis et al. 2017). Generally mining activities exposed land cover and badly affected the areas by stacking of soil mound,damaged rock particles, disintegrated materials etc. Mining disrupts soil characteristics like soil profile and structure, microbial populations and community, and nutrient cycles, which play pivotal roles in maintaining a healthy ecosystem and thus leads to destruction of native vegetation and soil horizons (Kundu and Ghose 1997) Based on geochemical characteristics and the mineralogical compositions of both ore and rocks, the degree of heavy metal contamination in soil varies, which subsequently affects plant and microbial growth (Iavazzo et al. 2012). The present study was conducted at the Frogmore mine site to evaluate the potential contaminants and its probable remediation measure to restore soil fertility and vegetation. This site is a derelict mine, which presents potential contamination problems. The current site covers open shafts and unsealed tailings and waste rock dumps that pose impending contamination threats that could potentially scatter offsite through acid mine drainage (AMD) and sediment spreading through surface runoff. Restoration of mine spoiled land is a highly expensive affair. Revegetation encompasses the most extensively recognized and practical way to lessen erosion and guard soils against degradation (Pardo, Bernal, and Clemente 2014). Although it is desired that the pristine conditions should be restored, reclamation of derelict mine land is a very intricate process.

Human population growth has increased food demands and expanded agricultural frontiers, land use, and forest area degradation, usually related to poor planning (Ferreira and Santos 2012). Revegetation techniques aim to restore degraded environments and mitigate environmental impacts (Chazdon 2008). Direct seeding, a technique of forest cultivation, has been increasing in ecological restoration programs in Brazil, with lower costs due to the elimination of seedling production (Benayas et al. 2009).
