Hi Ceasar: From what I’ve read of your comments on a couple threads, I have a link to something I think you will really, really enjoy seeing. As it turns out, there is an international colaboration of folks just like you who have either planted or discovered fruit, nuts, berries, etc growing on public lands/public places and have mapped them. I think there are even 11 or 12 in Puerto Rico (I think that is where you are?) so maybe there are already some close to you. (I saw Mangos, breadfruit, starfruit, and macadamia nuts all shown on the map of PR). You can plant more, then list them and one day contribute to the map.
It isn’t perfect, it isn’t always up to date, the produce isn’t always on truly “Public land” but is almost always a location where its fine to pick it (ie edge of parking lots, trees on private land but with limbs hanging over public sidewalks, etc). In short, it just seems like this map and the idea behind it is right along the lines of what you’ve been talking about and hoping to do. Take a look…I hope you like it!
