OpenStreetMap
It looks like all US national parks are being converted from leisure=park to leisure=nature_preserve.
The wiki doesn't give clear instructions about whether or not that's not the official way to do it. In official US NPS parlance, a nature preserve is not quite the same as a national park, but I understand that's not really the point. However, whereas the park region used to be rendered in this nice, understated transparent light green (very similar to official NPS maps actually), the nature_preserve has this butt ugly high saturation green with, at higher zoom level, an equally ugly 'NR' grid rendered onto it.
I know, I know, don't tag with the renderer in mind, but won't someone please think about esthetic sensibilities and all that?

The nature reserves only appear like that because that is how Mapnik is configured. Mapnik can be configured to render nature reserves in a different color. So it's not the tag that's the issue, but the default Mapnik rules I suppose.

Sorry, sent you a message when I really meant to reply to your post.

I know that's how Mapnik is configured. I think it's configured badly...

mapnik renders boundary=national_park too. For instance you can see the New Forest here in the UK: osm.org/go/eui8AK

OSM needs another tag for national park areas. At least in the U.S., national parks aren’t just reserves; they’re in large part recreational areas. So not only is this usage aesthetically poor, it’s semantically incorrect.
