surface=bark? I expect it to be woodchips made out of bark. Maybe it should be tagged surface=woodchips, see https://wiki.openstreetmap.org/wiki/Tag:surface%3Dwoodchips

(with optional woodchips=bark)

maybe if surface=bark is valid and should not be changed to surface=woodchips - consider posting about it on tagging mailing list, https://community.openstreetmap.org/ and/or editing that wiki page
