Minecraft wiki entry for Dirt_Path, associated text: Dirt paths are primarily used for decoration, although they also prevent hostile mobs from spawning. They are a similar color to grass blocks placed in a desert or savanna biome. They are only 15⁄16 of a block high, therefore items that require a full block like torches and buttons cannot be placed on them. Villagers and iron golems prefer to use dirt paths the most when routing compared to any other block.‌[Bedrock Edition only]
