Honeysuckle is killing forests and ivy is helping, especially in the northeast/midwest. Kill all that shit, help stop it from spreading. And try to volunteer for local groups that are clearing invasive species. It’s pretty amazing seeing a forest before and after invasive species have been removed.
I would guess on a small scale, we’re making progress. It’s much easier to manage on a small scale or if there is no exotic seed bank. For example, I’ve seen former agricultural fields look great 3 years after restoration.
There just isn’t a unified response to it. There are so many different entities that own and manage land it, you get different results.
I wish I knew about control of invasives in other countries and how serious they’re taking it.
