A national park is a relatively large area of land declared by a government (just as boundary=administrative are declared/recognised by governments), to be set aside for human recreation and enjoyment, animal and environmental protection. This would normally also come with restrictions on human activity, particularly development, for the protection of wildlife and scenery. National parks are often named “X national park” (with translation)

boundary=protected_area - A more recently introduced tag with a more verbose tagging scheme which can deal with all kind of protections and protection levels. It attempts to encompass both nature reserves and national parks, but so far been used less.

Т.е. как я понял :sunglasses: этот странный protected_area это чей-то очередной эксперимент из-за чесотки в одном месте. И он естественно мапником неподдерживается :D.
