I have been planting pollinator plants, both annuals and perennials in vacant/abandoned lots in my county. I try to do it when no one is looking as some people will destroy stuff just for the sake of doing it. For the last 15 years I've spread Diospyros virginiana (persimmon) seeds over a large range. Great wildlife plant that is also worth foraging. I've also spread a fair amount of riparian pollinator seeds in urban areas near me that have been stripped bare.
