Minecraft wiki entry for Warped_Forest, associated text: Because it has the least-rich diversity of mobs of any biome in the Nether, it is safer than the other Nether biomes. Like the mushroom fields in the Overworld, hostile mobs do not spawn in a warped forest. Numerous neutral endermen live inland, and striders are found in its lava regions. Fortresses and bastion remnants can also be found here.
