ysabetwordsmithEcosystem of Pansies Thrives on Soil Contaminated by Lead Mining–Turning it into Clean Organic Compounds
For areas contaminated by lead and zinc mining across Europe, a class of plants known as “metallophytes” are helping enrich nature while diminishing pollution.
The Guardian reported on this kind of ecological double speak, where wildflowers seemingly grow in healthy abundance on semi-mountainous landscapes in the north of the UK, a place that has seen lead and zinc mining since Roman times.
That is an awesome scenario.
English county authorities are at pains to decide what to do with these curious places: their existence is predicated on one or many neurotoxic pollutants, but the plants’ ability to take up the toxic heavy metal, and weave it into complex organic molecules in their roots which renders them nontoxic is not only saving millions of dollars in remediation work, but going on while the area is enriched from the food web diversity they help anchor.
When the biosphere figures out how to fix what humans fucked up, LEAVE IT ALONE while it heals.
Note that this ecosystem probably originated to handle natural disasters such as volcanic eruptions, which can spew out lots of toxic things. They are a different category of "bandage plants" similar to those designed to handle fire zones or landslides, and should be left to do their work in peace.

Some transfers might work, others not, depending on local details. The community of bandage plants is different in different places, as with other plants, and each plant has its own job description. Considering how little study humans have made of such things, and how they tend to dismiss most bandage plants as "weeds," I would proceed with caution.
