Definitely both, since a lot of people (myself included) don’t have anything resembling a good local landtrust. Evety tiny bit of park/public land/etc near me is like 99% amur honeysuckle, garlic mustard, and lesser celendine. None of the people ostensibly responsible for taking care of said land seem to care… 😭

Many conservation authorities look for volunteers for tree planting, invasive species removal, and cleaning up litter. They can be a great way to start helping your local areas.
