Biome

Biomes, also called ecosystems, are areas with specific height, light levels, vegetation, and types of blocks. As of 0.9.0, Pocket Edition has all PC 1.7.2 biomes with some shrunk to fit the height limit. As of now all biomes are Desert, Ocean, Tundra, Extreme Hills, Deep Ocean, Mushroom Island, Savannah. Roofed Forests, Jungles, Ice Plains, and the rare Mesa and Plataue biomes, as well as Forests, Plains, and Flower Forests, Mega Taiga, and Mega Spruce Taiga. The four biomes; Mega Taiga, Jungle, Roofed Forest, and Mega Spruce Taiga have been shrunk to fit Pocket Edition's height limit of 128 blocks. (It will go back to 256 blocks once Pocket Edition receives an update.)

Desert, Beach, and Oasis
A desert is a infertile biome consisting mostly of sand, sandstone (on layer 3 and 4), and sand dunes. Sugarcane can be found also in the desert biome if next to an ocean or a river biome.

Block Types
In the desert, mostly you will see, sand and sandstone on layers 3 and 4.

Height
The height of the desert is mostly sea level, but occasionally small hills form.

Vegetation
Plants such as cacti, and sugarcane (if near water, rare) can be found in the desert. As of 0.9.0, dead bushes will randomly spawn here.

Other notable features
Water is occasionally found nearby deserts. A beach is a biome like the desert but found near ocean biome. Cactus may occasionaly spawn in here. As of 0.9.0, Villages and Desert Wells may naturally spawn in Deserts. Rivers may also flow through deserts.

An oasis are mostly part of the desert biome with small patches of sand and a water source. Due to the heat, crops and trees take longer to grow.

Temperature- Dry: These biomes are very dry and hot. Not recommended for growing crops here.

Block Types
Dirt, usually with snow on the top. Water sources have ice on the top.

Height
Tends to be quite mountainous. Rarely totally flat.

Vegetation
Spruce trees can only be found in this biome. Grass blocks are located underneath the snow. The coldness of the biome makes it difficult for other plants to grow.

Temperature
Temp- (Cold): The coldness gives plants a difficult time to grow. Spruce Trees however are unaffected by the cold. Not recommended for plants.

Block Types
Mainly dirt and grass, with the somewhat rare patch of gravel.

Height
Rather close to sea level, but bumpy.

Vegetation
Oak and Birch trees, with sugar cane occasionally spawning near water. Mushrooms sometimes spawn underneath trees, where the light level is low enough. Two variations of the forest biome, the Birch and Spruce forests were added in 0.9.0.

Other notable features
Not safe to travel at night, because trees are very dense and can obstruct vision, but allow plenty of room for monsters to spawn. Creepers are especially a problem in this biome. It is probably the most common of all the current biomes. Spiders will spawn from the leaves.

Clearing
A small to medium sized area devoid of trees.

Birch Forest
Birch Forests are a type of forest added in 0.9.0. As the name suggests, it only has Birch Trees. The biome is flat.

Height
Relatively Flat Area

Vegetation
Birch Trees and Tall Grass.

Other Notable Features
Occasionally, an area devoid of trees.

Block Types
Mostly Dirt and Grass, Gravel forms (Rarely) in patches.

Height
Mostly Flat, but small to medium sized hills tend to form.

Vegetation
Mushrooms and Flowers, the area is rather barren of trees.

Other Notable Features
Very flat and grassy, making it the most suitable location to build large structures, but rarely far from a forest.

Block Types
Oceans are extremely large areas of water, sometimes extending for one hundred blocks in all directions, and can be as much as 40 blocks deep. The bottom consists of either dirt, sand, or gravel, and clay can sometimes be found near the shore.

Height
Sea level and can extend from 15-25 blocks deep, though can be up to 40 blocks deep

Other notable features
If you can create a solid surface to build on, it is the absolute flattest biome in the game.

Lake
Smaller bodies of water, usually up to about 5-10 blocks deep.

Block Types
Dirt, stone, and grass. Veins of Coal and rarely iron can be seen on the sides of the mountains. Emeralds can be found deep underground.

Height
Extremely hilly, mountains rise very high and are incredibly steep.

Vegetation
There is very little vegetation due to the lack of available space. Trees can sometimes spawn, and mushrooms spawn underneath overhangs.

Other notable features
This is the most unusual biome, overhangs tend to form and extend for quite a ways. Another common oddity is "Floating Islands", Where part of the terrain is suspended midair, with no apparent connection to any cliff or the ground. These are hard to access, but, if it is big enough, are among the most interesting places to build your home. The darkness of the overhangs can cause occasional Hostile Mob spawning.

Hills
Smaller mountains which are very common in most biomes.

Cold Beach/ Seaside Tundra
A rare occurance in which snow caps sand on a beach, but the water near does not freeze, and some sand may be left bare with Cactus on it.

Block Types
Usally snow, sand and water. Occasionally gravel.

Height
Sea-level, occasionally a large hill may rise near it.

Vegatation
Cacti, very rarely sugarcane.

Other notable features
An odd mix of biomes, and usually not very large. Sometimes a Desert will be present. There is almost always a Tundra Biome near this Mixed Biome, but sometimes there is simply snow on a beach. It should be noted that Cold Beaches should not have Ice instead of Water, because if it does it is a Tundra/Taiga.

Mushroom Island
The Mushroom island is a biome added to Minecraft PE in 0.9.0. The island consists of Huge Mushrooms, Mycelium, and Mooshrooms. It can be mountainous or relatively flat depending on the generator.

Height
Very tall trees and sometimes quite mountainous. However due to a height lag limit, it will be shrunken to fit.

Mountainous Jungle
As the name suggests, this a high altitude version of a jungle. It was added in 0.9.5. It is quite high and sometimes higher than extreme hills. Due to the darkness, sometimes mobs will spawn.

Other Notable Features
This is the only terrain where ocelots spawn (Note: Not in 0.9.0 however). Spiders may spawn in larger quantities due to high amount of leaves. Cocoa also grows from some of the wood. Moss stone Boulders, a rare naturally spawning object, can be found here.

Savanna Biome

Deep Ocean
The deep ocean biome is a variety of the Ocean Biome except the water goes down much much lower. Small islands can be scattered around. Sometimes the ocean connects to cave systems down below. In some cases, strongholds can be found in the water due to the world generation. Squids may spawn here. (Not in Update 0.9.0). This biome appeared in Update 0.9.0. Those who fall to the very bottom of the ocean may not rise to the surface without losing health, giving an example of how deep it can be.

Grass grows here. Oak is the most common tree with occasional birch and Dark Oak.

Height
Roofed Forests are very tall. There are some hills or mountains. Due to lag limit, it will be shrunken for Pocket Edition.

Vegetation
The grass is a normal green. Trees grow, but plants may grow slower on the ground due to the low light levels. Given enough space, Huge mushrooms can grow. Bioma

Far Biome
The far biome is a biome found at the edge of infinite worlds and will be added in 0.9.1. The pocket edition far lands is called the stripe lands. The biome is very far from the center of a world. It is also extremely laggish. The game also starts to crash around the biome.
