Decades of industrial growth have left an international environmental long-term problem. Soil and water are increasingly being contaminated with toxic and potential carcinogenic compounds and heavy metals. In the mining area, site conditions are normally very harsh for plant growth. Copper is a contaminant that is affecting our environment. In Southern California, copper is contaminating our waterways. These experiments were the first such study in this species and were used to assess the copper tolerance and resistance of the California native bush, Baccharis salicifolia (Mule Fat). Male and Female propagated cuttings were grown in sand and gravel mixture under greenhouse conditions. Copper was administered as a dilute solution of copper sulfate in water as in previous studies. Copper concentration was determined by previous research in various species. The results from this research showed that Baccharis salicifolia is resistant and tolerant to high copper concentrations and is an excellent candidate for remediation.
