All Strict Nature Reserves (World)

This group collects the 13 Protected Areas subcategory members that the atlas already places under its own Strict Nature Reserve subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Strict Nature Reserve stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Strict Nature Reserve subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Strict Nature Reserve subcategory page or the Groups index.
