A swamp biome.

A swamp is a temperate, murky biome. There are two variants of swamp.

Description[]

Swamps are mostly flat biomes, with elevations low enough to go below sea level throughout much of the area. Large portions of swamps are flooded, from marsh-like patches of single blocks of grass forming in shallow water, to large lakes, with patches of clay on the lakebed. Water in swamps takes on a gray-green color at the surface, turning pale yellow when submerged in it. Unlike most biomes, swamps have varying temperatures, which affects the color of grass blocks, grass and leaves.

Vegetation includes oak trees, that can grow in shallow water and generate with vines growing on them. Sugar cane is found often growing on shores, while seagrass litters the bottom of flooded areas. Blue orchids may grow among the grass, while lily pads dot the surfaces of lakes; both are found exclusively in swamps. In Bedrock Edition, huge mushrooms can generate as well.

Rarely, a swamp may include a swamp hut, housing a witch and a black cat. Only witches can spawn in and around the hut. Swamps, alongside deserts, can generate fossils, rare structures found underground around Y=50.

Slimes can spawn in swamps at low light levels, alongside common monsters, between elevations of Y=50 and Y=70 (exclusive). Their spawn rate is affected by the moon phase, spawning most often during full moon and not spawning at all during new moon.

Villagers that spawn in swamps get a unique swamp-themed look. While villagers have swamp-specific types, no village featuring exclusively these villagers can be generated. The only way for these villagers to spawn is either by being bred in swamp or curing a zombie villager that spawned in a swamp.

Swamp biomes are usually found next to other lush biomes, such as forests, dark forests, birch forests, and plains biomes. Like aquatic biomes, swamp biomes undergo little to no change when generated in the Amplified world type.‌[Java Edition only]

The swamp biome is the standard swamp variant. Non-flooded areas of this biome feature relatively flat terrain, similarly to plains biomes, though with significantly more trees and less tall grass. In Java Edition, some parts of the swamp may have marsh-like terrain, where the grass has multiple single blocks of water generating within it. At nighttime, depending on the moon phase, slimes may spawn at Y-levels 50-70 alongside other hostile mobs, making swamps the only places aboveground where slimes can be found. Swamp huts and fossils also generate in this biome.

The swamp hills variant featured hillier terrain rising up between the flat marshes. These hills would tower over the otherwise low-elevation swamp. Additionally, flooded areas in swamp hills tended to reach lower depths than the rest of the swamp, sometimes deep enough to have a gravel floor in place of a dirt floor, like normal oceans. Swamp huts did not generate in swamp hills‌[Java Edition only], nor did slimes spawn, but fossils did still generate underground. Additionally, seagrass did not generate in flooded areas of swamp hills. If it connected to a sparse jungle it had a chance to create a modified jungle edge biome.

Swamp hills used the same mob spawning chances as swamps.
