<span style="font-family: Calibri, Helvetica, sans-serif; font-size: 11pt; line-height: normal;">Facilitating the establishment of native pioneer plant species on mine tailings with inherent metal and/or acid tolerance is important to speed up natural succession
at minimal cost, especially in remote areas where phytoremediation can be labor intensive. We investigated vegetation community dynamics after

and waste rock deposits in the Sudbury Basin, Ontario, Canada with and without various site amendments (i.e. liming and fertilization) and planting. Metal/acid tolerant pioneer plants (</span><span style="font-family: Calibri, Helvetica, sans-serif; font-size: 11pt; line-height: normal;"><i style="line-height: normal;">Betula

tolerant to site conditions were planted at the fully amended (limed, fertilized, planted) mine tailings site in the 1970s, but conifers were not propagating at the site or facilitating understory succession. The planted nitrogen-fixing leguminous species

phytoremediation.</span><o:p><span style="font-family: Calibri, Helvetica, sans-serif; font-size: 11pt; line-height: normal;"> </span></o:p></p>
