We're looking at the super-low-bar of doing things like removing known invasive plants as published in the state's DNR. They maintain a yearly list of nasties to remove.
We also don't use any chemicals to do the killing, as so many of those have terrible side effects. Killing larger invasives involves something as simple as "black contractor bag enveloping and tied at base". It captures all the seeds, kills the plant, and provides easy removal.
We also see that a lot of "lawn grasses" are also pretty invasive especially to forests. So, we also try to keep the lawn encroachment from happening..... as much. Ive done the high tech solution of "lay a slab of plywood on the grasses at the edge of the forest"!
We're also designing our garden with local plants in mind, including rarer plants for our area. If/when those flower and seed, we're seeing natives with natives. And the non-natives we bring in are checked for invasiveness.
Basically, it's being low-key stewards to the land.
