> Our trees accumulate metals from the soil, making their wood less digestible to fungi

Given that fungi play a crucial role in decomposition and also water/nutrient exchange between living plants, do you think there are any major risks from second order effects? Particularly if these plants become well established and dominate a local ecosystem?

And as a follow up question, does the increase in metallic content pose any extra risks when burning in a forest fire? Perhaps through emissions or thermodynamic effects.

Very interesting idea, good luck and thank you for the thoughtful commentary here.
