Effects of 15-Year-Old Plantation on Soil Conditions, Spontaneous Vegetation, and the Trace Metal Content in Wood Products at Kipushi Tailings Dam

Phytostabilization is a more appropriate way for rehabilitation of metal-polluted environments in the Copperbelt region. A 1.5-hectare tree planting trial had been installed on tailings dam (TD) with help organic matter (OM) mixed to topsoil. Then, 15 years later, this study aimed evaluate performance plantation, regard soils and spontaneous vegetation. The Cu Co concentration was higher reclaimed soil compared unreclaimed. Acacia auriculiformis , polyacantha Albizia lebbeck Pinus sylvestris Psidium guajava Senna siamea spectabilis Syzygium guineense responded well criteria phytostabilization, whereas Leucaena leucocephala very invasive. Metal manifold charcoals than woods (Zn: 3.8–39.8 mg kg ?1 wood versus 272–523 charcoal) no differences between regardless origin. implantation aided amendments can meet phytostabilization through good survival regeneration heavily contaminated TD.
