“…Tree species that take up Cd or Zn from the rooting zone obviously translocate those trace metals to their leaves, as reported before (Alriksson and Eriksson, 2001;Hammer et al, 2003;Meers et al, 2005;Mertens et al, 2007;Unterbrunner et al, 2007;Vervaeke et al, 2003).…”

“…It is generally known that plant species can differ in their effect on soil pH, organic matter content and CEC, and differences between tree species for these soil characteristics have been reported in the past (Augusto et al, 2002;Finzi et al, 1998;Hagen-Thorn et al, 2004;Mertens et al, 2007;Nordén, 1994;Reich et al, 2005). In the present study, all tree species except aspen, tended to decrease the pH slightly, but not (yet) significantly, in the topsoil compared to 20-30 cm (Table 5).…”

“…and Salix spp. are known to take up Cd and Zn from polluted soils and to accumulate these metals in their biomass, including branches, leaves and wood, distinctly more than other tree species (Brekken and Steinnes, 2004;Hassinen et al, 2009;Laureysens et al, 2004;Mertens et al, 2007;Unterbrunner et al, 2007;Vandecasteele et al, 2003). The Cd and Zn concentrations measured in the biomass of aspen (Populus tremula) are in line with these reports.…”

“…Sandy soils are characterized by a low CEC and a low acid neutralizing capacity, which makes them more vulnerable to acidification. The differences in topsoil pH between the species can probably be attributed to the chemical properties and the decomposition rate of the different leaf litter types (Hagen-Thorn et al, 2004;Mertens et al, 2007;Reich et al, 2005). Retarded litter decomposition leads to the production of organic acids and delays the return of base cations to the soil, which will result in lower pH values (HagenThorn et al, 2004).…”

“…Consequently, the distribution and fluxes of metals in biomass, litter and mineral soil will be species specific as well (Alriksson and Eriksson, 2001;Mertens et al, 2007;Watmough et al, 2005). Selecting appropriate tree species is thus crucial for achieving successful phytostabilization.…”

Phytostabilization of metals using trees is often promoted although the influence of different tree species on the mobilization of metals is not yet clear. This study examined effects of six tree species on the soil characteristics pH, organic carbon (OC) content and cation exchange capacity (CEC) and on the redistribution of cadmium (Cd) and zinc (Zn) on a polluted sandy soil. Soil and biomass were sampled in 10-years-old stands growing on former agricultural land. The tree species included were silver birch (Betula pendula), oak (Quercus robur and Q. petraea), black locust (Robinia pseudoacacia), aspen (Populus tremula), Scots pine (Pinus sylvestris) and Douglas fir (Pseudotsuga menziesii). In the short period of ten years, only aspen caused significant changes in the soil characteristics. Due to accumulation of Cd and Zn in its leaf litter, aspen increased the total as well as the NH 4 OAc-EDTA-extractable Cd and Zn concentrations in the topsoil compared to deeper soil layers and to other tree species. Also topsoil pH, OC content and CEC were significantly higher than under most of the other species. This caused rather low 'bio-available' CaCl 2 -extractable concentrations under aspen. Nevertheless, given the risks of aboveground metal dispersion and topsoil accumulation, it is recommended that aspen should be avoided when afforesting Cd and Zn contaminated lands.

Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. This has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require it. Nevertheless, ecological restoration remains a young and rapidly growing discipline and its intersection with toxicology is even more nascent and underdeveloped. Consequently, we provide guidance to scientists and practitioners on when, where, and how to restore contaminated ecosystems. Although restoration has many benefits, it also can be expensive, and in many cases systems can recover without human intervention. Hence, the first question we address is: “When should we restore contaminated ecosystems?” Second, we provide suggestions on what to restore—biodiversity, functions, services, all 3, or something else—and where to restore given expected changes to habitats driven by global climate change. Finally, we provide guidance on how to restore contaminated ecosystems. To do this, we analyze critical aspects of the literature dealing with the ecology of restoring contaminated ecosystems. Additionally, we review approaches for translating the science of restoration to on-the-ground actions, which includes discussions of market incentives and the finances of restoration, stakeholder outreach and governance models for ecosystem restoration, and working with contractors to implement restoration plans. By explicitly considering the mechanisms and strategies that maximize the success of the restoration of contaminated sites, we hope that our synthesis serves to increase and improve collaborations between restoration ecologists and ecotoxicologists and set a roadmap for the restoration of contaminated ecosystems.
