If by any chance some of you find this discussion, I'll be happy to receive your opinion on this.
Basically, all these forest paths are public paths but vehicles aren't allowed, thus most of them is closed off with barriers (Polish law). Setting "All" access to forestry makes the path on the map to look unaccessible, regardless if you specified pedestrian/bike/horse to yes. So I think it's better to keep "All" access to "yes" and then, as for the vehicles change it to "no" (as they are not allowed) or "forestry", because forest services are the only ones that can enter with vehicles?
