Fifteen poplar plantings from nine long-term phytoremediation installations were sampled from 2012 to 2013 in the U.S. Midwest (Illinois, Iowa, Wisconsin) and Southeast (Alabama, Florida, North Carolina). Performance sampling results at each site were compared with similar phytoremediation systems in the literature. Review of significant genotypic differences from each planting was performed for biomass production and carbon sequestration ecosystem services. Results show that phytoremediation success can be increased by appropriate selection and deployment of poplar genotype, whether generalist genotypes, which are tailored to grow well and tolerate a broad diversity of contaminants, or specialist genotypes that significantly outperform their counterparts under unique site conditions. Overall, the contaminated poplar sites provided ecosystem services comparable to uncontaminated poplar sites used for bioenergy and biofuels feedstock production.
