All Wetlands and Tidal Flats (World)

This group collects the 12 Bodies of Water subcategory members that the atlas already places under its own Wetlands and Tidal Flats subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Wetlands and Tidal Flats stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Wetlands and Tidal Flats subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Wetlands and Tidal Flats subcategory page or the Groups index.
