I think this more reads like "How to fight non-native species with native species".
The definition of invasive doesn't really lend itself to an easy change-out. Truly invasive are the plants that modify the entire ecosystem, brings trees down, swamps everything else, spreads easily, difficult to eradicate etc.
I work in the invasive plant industry and I wish it were that easy. Sure, some jobs are "remove the exotics" but that's simple work compared to the true monsters.
