Biomes are regions or the terrain in a Minecraft world with varying geographical features, flora, Mobs (fauna), elevation, temperatures, sky colors and foliage colors.
Introduced in the Halloween Update, biomes separate every generated world into different environments, paralleling the real world. Examples of biomes include the forest, jungle, desert and tundra. Prior to the Halloween Update, every world had only a single theme, either grassy or snowy.
The term biome is analogous to its scientific usage: on Earth, a biome is climatically and geographically defined by distinctive communities of plants, animals and soil organisms supported by similar climatic conditions. They are often referred to as ecosystems.
Main article: Plains Biome
Plains are the most basic of all lands, but the easiest to obtain food due to grass (seeds) and the spawning of farm animals, which are more abundant than in other biomes.
Subtype: Sunflower Fields
Sunflower fields are plains that produce a naturally occurring abundance of sunflowers.
Subtype: Wild-flower Fields
A variation of either plains or forest biomes, wild-flower biomes are easily identified by the massive amount of flowers growing.
Main article: Forest Biome
The forest biome is mainly made up of trees. The type of tree can vary, but the oak tree is the most common type of tree in a forest.
Subtype: Birch Forest
This biome only includes Birch Trees, with some Oak Trees possible. It also looks much like a forest biome, although none of the birch trees can be large like their oak variants. However, if it's a hilly version of this biome, the birch trees can be extra tall.
This biome consists of oak trees and sometimes large oaks. Ferns, yellow flowers, red flowers, sheep, pigs, cows, and on occasion, packs of wolves, all naturally spawn here.Subtype: Pine Forest
Pine forests consist of pine trees. Most often pine forests are found as Taiga biomes with snow, though some can spawn warm enough to rain.
Subtype: Flower Forest
Flower Forests are forests with oak trees, but have many different types of flowers scattered around the area.
Roofed Forest ("Dark Forest")
Main article: Roofed Forest Biome
The roofed forest biome was added as of 1.7.2. It's a subtype of the forest biome. It features dark oak trees and huge mushrooms. The roofed forest biome is a very dangerous biome to spawn in as there are many dark places in the forest where hostile mobs are likely to spawn. It's also a more common biome than the mushroom biome, which makes it a better place to search for if someone wants to find giant mushrooms.
Main article: Swamp Biome
Swamp Biomes feature shallow bodies of discolored water and discolored grass, with oak trees covered in vines. Slimes and Witch Huts can be found in swamps. Swamp biomes are the only natural source for Lily Pads, which can generate in water. This is also the only biome to find naturally-occurring Blue Orchids.
In Minecraft: Pocket Edition, Giant Mushrooms spawn in this biome as of the 0.10.0 update.
Main article: Jungle
Jungle Biomes are very forested biomes. They have the tallest trees of any biome. Similar to swamp biomes, the trees are covered in vines. This is the only biome where ocelots spawn. They also occasionally contain a Jungle Temple. Jungles look similar to a Tropical Rainforest. Cocoa Pods grow here, and as of 1.7.2, wild Melons can also be found.
Main article: Taiga
A biome with densely filled spruce trees and dull grey-blue grass. Hills are common, and wolves are found in this biome more frequently than in others. Spruce Trees cover the landscape. Water will freeze into Ice. Sugar Cane can spawn here, but it will break down due to the freezing of the ice. The main difference between Taiga and Tundra is the amount of trees (more in a Taiga) and amount of snow (more in a Tundra).
Subtype: Cold Taiga
Contains densely filled spruce trees with lots of snow and ice.
Mega Taiga (Redwood Forest)
Main article: Mega-Taiga Biome
The Mega Taiga Biome is a subtype of the Taiga biome with a variant called Mega Spruce Taiga. It contains various blocks, including Podzol and a variant of Dirt. Also featured are 2x2 Spruce Trees, along with Ferns, Mushrooms, and Dead Bushes. This biome also features boulders made of Moss Stone that serve as a decorative purpose.
Ice Plains (Tundra)
Main article: Ice Plains Biome
Tundra biomes, known as Ice Plains in-game, are biomes completely covered in snow and have ice blocks due to water freezing (breaking ice produces water). Spruce trees are found in this biome. Wolves also spawn here. When it rains in other biomes, it will snow in this biome.
Subtype: Ice Spike Plains
Ice Spike plains are a variation of the ice plains, and much rarer. Relatively few trees will grow in these plains. Large "spikes" of packed ice can be found throughout. Bodies of water will typically be frozen into packed ice, as opposed to the Tundra's regular ice (suggesting the Ice Spike plains are severely colder).
Main article: Mesa Biome
The Mesa Biome features various colours of clay and natural hardened clay that can be mined and dyed for decorated purposes. Also found in this biome is red sand, which was implemented in 1.7. Other things included in this biome are Dead Bushes and occasional Cacti. Mesa biomes are rare, and usually spawn near Savanna biomes.
Main article: Desert Biome
The desert biome is the most abundant source of cactus. There are hills and small mountains made of sand and sandstone. In the desert you can also find desert wells. Desert temples also spawn in large deserts.
Main article: Savanna Biome
This biome features dull, dry grass, and acacia trees. NPC villages spawn naturally here, along with horses. It never rains in this biome, often connected with deserts or mesas (if you create a new world using the seed "Indev", you will spawn next to a Savanna biome with a Desert biome connecting to it).
Main article: Ocean Biome
Ocean Biomes are extremely large open biomes made of water. Far beneath the water is a landscape made of gravel, dirt, and clay. Ocean biomes often flood into Abandoned Mine Shafts or caves. Occasionally, oceans have small two block wide air patches. Ocean biomes have no maximum size but usually are found between 10,000 and 25,000 blocks wide. Occasionally, in Ocean biomes, you can find small islands with little vegetation. Players can spawn in Ocean biomes on an island with no wood in the middle of nowhere forcing them to cheat, make a new world, or swim to find land.
Subtype: Deep Ocean
Deep ocean biomes are a variant of ocean biomes. They are much deeper than regular ocean biomes. The ocean floor consists of gravel. They can be 30 blocks deep, making underwater exploration dangerous. However, you may encounter light underwater, which comes from Abandoned Mine Shafts. As of update 1.8, deep ocean biomes generate Ocean Monuments (ocean temples) surrounded by hostile Guardians.
Main Article: Mushroom Island Biome
Mushroom islands are a rare biome. Instead of dirt, mushroom islands utilize Mycelium. Mushroom islands are typically found away from other land biomes, near or in ocean biomes. Giant mushrooms grow in place of trees, and the naturally occurring mobs are Mooshrooms. Dirt placed on a mushroom island will eventually be turned into Mycelium, much like grass in other biomes. Farmland is resistant to Mycelium change.
Main Article: Extreme Hills Biome
A highly mountainous biome with dull grey-blue grass and a few scattered oak trees.
Cliffs, peaks, valleys, waterfalls, overhangs, occasional lavafalls, and many other structures exist, creating outstanding views. More underground cave systems are present here than in any other biome. Falling is a significant risk, as there are many ledges and sudden drops, often not visible, and the drops can be large enough to cause severe fall damage, or even death.
Extreme Hills (and Extreme Hills Edge) are the only biomes where Emerald Ore spawns abundantly. As of 1.7, Spruce Trees spawn here as well. If the mountain gets high enough, snow could cover the mountains.

Each of the biomes listed above generates exclusively within the Overworld. However, there are areas of a Minecraft world which are far larger, but share similar characteristics to a biome (they generate unique landscapes, structures, mobs etc). The "zones" in this separate category can only be reached by using a specific method and typically have a brief loading screen as a player enters one. They are, in some ways, considered as entirely separate worlds.
Main Article: Overworld
The Overworld is the regular game play world containing each of the biomes listed above. This is the world the player will spawn and spend the majority of the game.
The Overworld can be generated when creating a new Seed as Default, Superflat (No biomes), Large Biomes, Amplified (Data heavy - large mountains and hills that dwarf the Default Hilly Biomes), and Customized (allows player to decide what structures generate more or less and to any extent desired).
Main Article: The Nether
This biome is the Nether dimension. It is the first dimension that was released with the game. This biome features more mobs and the Nether Fortress. The only way to get to the Nether is to build the portal made out of Obsidian and light it with a flint and steel.
Lava is abundant, and the floor is replaced with Netherrack - some with fire burning infinitely, Soul Sand, Glowstone, and occasionally gravel pits. Nether quartz can be mined and turned into decorative blocks. Maps can be made, but are ultimately not useful as areas tend to look identical. Compasses and Clocks do not work and will instead flux erratically. Beds placed in the Nether explode when clicked with the same damage as lit TNT. Water can not be placed anywhere within the nether.
In this realm mobs that spawn naturally include Ghasts, Zombie Pigmen, Blazes, Magma Cubes, Skeletons, Wither Skeletons, and Withers. Chickens can be spawned by throwing eggs, which in turn can create Zombie Pigmen Jockies if a baby Zombie Pigman mounts a chicken.
Main Article: The End
The End is a series of floating islands in a black, static filled void. It is the second dimension that was added in update TU9 for consoles and 1.0 for all other releases. In this zone, the ground is replaced with End Stone.
The end features many Endermen and the Ender Dragon boss. The landscape is dotted with Obsidian pillars topped with Ender crystals, which heal the Ender Dragon as you battle. Destroying these is key to defeating the dragon.
Once in the End you can not return without either dying or defeating the ender dragon (which opens the return portal). This also "finishes" the game (Gameplay resumes as normal after the end credits.). In the end, compasses, clocks, and beds do not work, behaving the same as they do in the Nether.
To get to the end, you will need to collect Ender Pearls from Endermen in the player realm, create 12 Eyes of Ender (using Blaze Powder and an Ender Pearl), and locate a stronghold using the Ender Pearls (Thrown in to the air and following their path. Some disappear so you will need many, especially if the stronghold is far.). Once in the stronghold the player must navigate the expansive ruins and locate the broken End Portal Frame (Be weary of Silverfish which will spawn throughout, but a silverfish Mob Spawner is located by the portal), using the Eyes of Ender on the 12 tables, and opening the portal to the End.
Outer End/End City
Main Article: End City
The outer end is another part of the end, with the main feature being one or more end cities. You can get there by killing the Ender Dragon and then tossing an Ender Pearl through the one-block portal in the sky. An End City has many islands and like the end, they are surrounded by a void. Chorus Plants are the only vegetation native to this zone. Endermen and Shulkers are common within an end city. An End City area can have several different types of tower-shaped structures and an end ship, each filled with loot. There are Purpur Blocks and End Stone Bricks are exclusive to this zone.
