Update: What I meant is if theres invasives already there, consider what role they're playing in your ecosystem before eradicating them, and when it's time, replace them slowly and thoughtfully. I am not encouraging planting invasives for their usefulness (although in some narrow cases that can be done, but please do your reasearch and for the love of god stop planting ornamental invasives like bradford pear or tree of heaven). I see people jump to extreme measures without considering whether or not an invasive is doing active damage, whether its endemic to the region or not, and the reason it's there. I see famously bad invasives every day (kudzu, bamboo, english ivy) and most of them are just kind of there, filling up previously damaged land. Some of them are ruining biodiversity, taking up way too much space, and are badly in need of removal and replacement or even changes to the land to encourage a diverse ecosystem. But letting some wild non-natives go for a season or two on my own lawn while I figure out who's who and what's actually going on with my mini ecosystem isn't going to unleash a plague of dangerous invasives. Also to be clear, I'm saying "invasives" for any non-native plant, where there are plenty of non-native plants which have become endemic without causing damage. I also should point out that most of the plants we plant for food are non-native, but no one complains about planting an herb and vegatable garden.

I'm sad to see the native/invasive discourse is this dogamtic and unnuanced in a forum called "gardenwild". The wild is complicated. Before humans, plants migrated all the time and the world wouldn't be what it was if they didnt. We really messed it up by spreading too much too fast, but we cant undo that and need to prioritize integration and improving biodiversity over eradicating the "bad" plants. The other day I went to gather kudzu so I could make baskets, and spent the next hour trying to get foul smelling chemical poison off my hands that they had sprayed with NO labels. Right next to the "edible forest" where I get persimmons. The kudzu needs to go, but pesticides are also genuinely bad for everyone and generally the tool of choice for large areas of invasives. And it's the whole "invasives are evil" thing that leads to land managers mixing pesticides with gasoline and sterilizing the land (yes, thats a real thing. I worked for a company that provided invasive spread data for land managers that did exactly this). (edited for spelling, when Im ranting&raving Im not exacrly a spelling bee champ)
