Manganese

Hyperaccumulation threshold: 10,000 µg g⁻¹ [ref] Primary

Manganese hyperaccumulators are predominantly woody species from the tropics and subtropics, especially Australia, New Caledonia and East Asia. Unlike Zn/Cd hyperaccumulators they do not necessarily grow on strongly metalliferous soils, suggesting a distinct physiological strategy.

6 species recorded in this database; highest cited value 55,200 µg g⁻¹.
