All Grasslands and Savannas (World)

This group collects the 19 Landforms subcategory members that the atlas already places under its own Grasslands and Savannas subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Grasslands and Savannas stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Grasslands and Savannas subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Grasslands and Savannas subcategory page or the Groups index.
