All Natural Monuments or Features (World)

This group collects the 40 Protected Areas subcategory members that the atlas already places under its own Natural Monument or Feature subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Natural Monument or Feature stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Natural Monument or Feature subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Natural Monument or Feature subcategory page or the Groups index.
