I've reverted this changeset since it deleted many features which quite likely still exist including a waterway=stream, a natural=wood and highway=track.

Please see https://wiki.openstreetmap.org/wiki/Why_can%27t_I_delete_this_trail%3F and https://wiki.openstreetmap.org/wiki/Why_we_won%27t_delete_roads_on_private_property for details on why features which exist on private property may still exist in OpenStreetMap.

If there are firetrails, driveways or walking tracks which don't allow the public to use but do exist on the ground you can use http://wiki.openstreetmap.org/wiki/Tag:access=private to mark them as no public access.
