Thanks very much for the explanation - I think I'm still only scratching the surface here. Anyway, I'll see if I can extend my xslt mangling to detect this kind of thing. Looks possible with a couple of regexes. ><http://wiki.openstreetmap.org/wiki/Special:Search?search=conservation&go=Go> Yep, http://wiki.openstreetmap.org/wiki/Proposed_features/conservation is yet another example of a proposal that appears to have run out of steam. I don't think the proposal process is working. I also confess to not understanding the difference between land_use=nature_reserve and land_use=conservation after reading that page. Fwiw, I would have thought it makes more sense to tag/render it as a boundary rather than the area itself.
