Minecraft wiki entry for Badlands_(old), associated text: The modified badlands plateau featured smaller plateaus and somewhat harsher terrain than the badlands plateau, mimicking large plateaus that have weathered more over time. Eroded badlands replaced the usual thin desert border that this biome variant shared with other biomes. The modified badlands plateau was the second rarest biome in Minecraft, after modified jungle edge, and was only present in about 1/5 of the badlands biomes, and almost always (98% chance) came with an eroded badlands bordering the edges and modified wooded badlands plateaus surrounding it at the center.
