if you think it’s potentially invasive for some reason, then first get it identified either through iNat or via, say, an Agricultural Extension Service. once you know what it is, you can check with state and/or federal agencies or legal code / regs (agriculture, fish and wildlife) to see if the authorities have anything to say about that particular species. sometimes they will want to know about them so that they can come out and do a more thorough investigation. sometimes, you can just dispose of it, or leave it as it is.
