Osm was really crappy two- three years ago where I live (europe) but now it is better than google maps, a lot has happened. Also, I go hiking and canoeing alot, and there is a lot more info on osm than on goggle now outside cities, like shelters, camping grounds, firepits, hiking trail, mtb-trails. I dont know if the outdoorspeople are good at updating osm.

I prob have something similiar to bottom pic, and I would say it is much easier to maintain than a grasslawndessert. I have some garden paths and spots that I trim down, and cut down bushes when they get to big once a year, but never use a lawnmower or bother about weeds. Mosquitos are less now that I have more birds, a tawny owl is living in a hollow tree close to my compost and takes care of rodents. Dug a pond and got lots of frogs that also eats insects.
