Community Service - Pulling Invasives?

There’s also a forgiveness/permission issue here. My inclination (speaking only for myself and not anyone else) would be to reach out to whoever manages the preserve and say “I would like to volunteer. Ideally I’d like to help plant natives and remove invasives. In the meantime I’ll go ahead and remove any egregious invasive I am confident I recognize. Please advise how I can best contribute.” Then do what you need to do, prioritizing doing no harm.
