Minecraft wiki entry for Desert, associated text: Desert biomes are quite barren, with the only vegetation being cacti and dead bushes. Among the mobs that can spawn in the desert, only rabbits spawn in the wild, while villagers, cats, cows, sheep, and pigs appear in desert villages. The surface is made entirely of sand, with sandstone generating underneath the sand to prevent it from falling into caves below. lava ponds may still generate; water may still generate if the altitude dips low enough, allowing for sugar cane. Deserts make up for their barrenness by featuring a relatively large number of structures, such as pillager outposts, villages, desert pyramids, fossils, and desert wells. Villages and desert temples may offer refuge and valuable loot, desert wells may serve as a rare source of water, and fossils can provide large numbers of bone blocks and bone meal, or simply a neat paleontological find, while pillager outposts are the only source of wood on the desert surface.
