mine-site-rehabilitation
Mine-site rehabilitation is the process of restoring plant communities and ecological function to land that has been disturbed by mining activities, typically involving soil remediation, revegetation, and the reestablishment of native flora. For plant scientists, it provides a critical applied context for studying stress physiology, heavy metal tolerance, and plant-soil interactions under extreme conditions. Research in this area informs strategies for selecting and breeding resilient plant species capable of surviving contaminated, compacted, or nutrient-depleted substrates.

Coal mining devastates air, soil, and water quality across mining regions worldwide. This review finds that using plants to clean up contaminated land — a method called phytoremediation — offers a cost-effective, sustainable alternative to conventional cleanup methods, especially when combined with modern techniques like microbes, biochar, and genetic improvements.
Conventional cleanup methods like topsoil replacement and water spraying are limited in effectiveness, site-specific, and costly — making plant-based remediation an increasingly attractive alternative.
Different plant functional groups (grasses, shrubs, trees, aquatic plants) play distinct roles in stabilizing, extracting, or breaking down heavy metals and other mining contaminants in soil and water.
Emerging enhancements — including microbe-assisted growth, biochar integration, nano-scale materials, and genetic improvement of plants — can significantly boost phytoremediation performance at real-world field scale.
