Description	Plants capable of accumulating exceptionally large concentrations of metals such as Zn, Cd, Ni, and Pb have been termed hyperaccumulators (Brooks et al., 1977). Unlike most plants, these species typically maintain high tissue concentrations of metals across a wide range of metal concentrations in the soil. Metal hyperaccumulation is an extreme evolutionary response to the presence of high metal concentrations in soils and is not a common characteristic among terrestrial higher plants. A number of hyperaccumulating species endemic to metalliferous soils have been reported (Baker et al., Chapter 5). Notable metal-accumulators include several members of the Cruciferae. For example, Alyssum and Thlaspi species native to serpentine soils can accumulate concentrations of Ni in excess of 2% on a dry matter basis (Brooks and Radford, 1978; Brooks et al., 1979; Reeves and Brooks, 1983a), while species of Thlaspi from Zn/Pb mineralized soils can accumulate Zn to more than 2%, Cd up to 0.1%, and Pb up to 0.8% (Shimwell and Laurie, 1972; Reeves and Brooks, 1983a; Reeves and Brooks, 1983b).
