With the Great Lakes Restoration Initiative, the Forest Service works in partnership with cities, counties, and corporations to install phytoremediation
sites. The initiative is in its fourth year of annual funding, and altogether, about 20,000 trees have been planted at 16 phytoremediation sites in the Lake
Michigan and Lake Superior watersheds. The trees are mostly fast-growing willows and poplars, which are ideal for phytoremediation because they grow quickly
and have deep and extensive root systems. https://www.usda.gov/media/blog/2019/08/ ...
