Mushroom Cultivation
Invasive plants can be used as substrate to grow edible and medicinal mushrooms. Many sites with invasive plants have experienced disturbance and contamination that gave way for those plants to move in in the first place. Be cautious of the substrate you are growing mushrooms for consumption on.
Forest Care with Fungi is an amazing project that explores growing edible and medicinal mushrooms on introduced plant matter. They've detailed a process for growing oyster mushrooms and other species!
