Hi jepee,

please don't map single trees as landuse=forest (see here, for example: https://www.openstreetmap.org/way/1288931753). You can use a single node with natural=tree for that. And for tree rows, you could use natural=tree_row instead of a landuse polygon (see here, for example: https://www.openstreetmap.org/way/1288931747). It's more accurate to map a single tree as such and not as landuse, which is applied to areas.
