Whether phytoextraction or phytostabilization is the goal, plants used need to be suited to the climate at the mine tailings site. In temperate regions tailings are often saturated or waterlogged and require plants adapted to slightly anaerobic and wetland conditions (Craw et al. 2007).In arid and semi-arid regions plants must be both drought- and salt-tolerant to tolerate …
