Biome

Biomes, unofficially called ecosystems, are areas with specific height, light levels, vegetation, and types of blocks. Minecraft Pocket Edition currently has most PC 1.7.10 biomes with an exception of a few such as Amplified. In total, Pocket Edition has 29 biomes.

Snowy
These biomes are known for their inclusion of snow and ice. These areas are not good for crops.

 * Frozen River
 * Ice Plains
 * Ice Plains Spikes

Neutral
These biomes are either completely filled with water, or have tons of variants that vary depending on their biome.

Neutral Biomes

 * Ocean
 * Deep Ocean
 * Hills and its variants

Plains
The Plains is a basic, common biome that features some small trees, lots of grass, small pools of water, and the occasional lava pit.

Temperature
Lush.

Unique Mobs, Items, and Resources
None.

Reasons to Visit
This is a great place to build a home. It features lots of open space, can border relatively any biome, and features both hostile and passive mobs. Also, players may come here to get small amounts of trees.

Good for a Base?
Yes. It has lots of open space and is the perfect place for crop growing. You should definitely come here to build any kind of base.

Desert
Sparse of life. The Desert doesn't have much to feature besides cactus.

Temperature
Dry.

Unique Mobs, Items, and Resources

 * Cactus - A resources made exclusively for decoration or as a weak attacking tool. Cactus can also be used as a trap or "garbage can", as it damages anything that touches it, and also gets rid of items dropped near it or into it.
 * Dry Bush - Dry Bushes are completely dead bushes that can be sheared for decoration, but serve no other use.
 * Sandstone - Basically the sandy variant of Cobblestone. However, it takes less time to break by punching (about as much time as it takes to break one normal piece of Wood) and is very useful for building houses if the player prefers to use it.
 * Desert Village - A variant of a Village that is only found specifically in Desert biomes. It is made completely out of Sand, Sandstone, and small amounts of Cobblestone.

Reasons to Visit
Well, Deserts are full of rare resources; Dead Bushes, Cacti, and much more. Also, at some point, you will want glass, which is smelted from sand. Sand that falls may also giveaway to dungeons.

Good for a Base?
Not really. Deserts feature no wood, passive mobs, or much water at all. This means that living in a Desert would be hard. Only build a base on the borderline of it and another biome; preferably a wood-filled one, like a Forest or Jungle. However, note that the flat appearance of deserts allow lots of sighting for monsters at night.

Extreme Hills
The Extreme Hills is a huge, steep, mountain-like biome that is the perfect home for master miners.

Temperature
Cold.

Unique Mobs, Items, and Resources

 * Emerald Ore - Found exclusively in this biome, Emerald Ore and Emeralds mostly just serve as a way to craft an Emerald Block, which is used for decoration only. This means that trying to find these is mostly a waste of time, although you should get it if you just randomly find it. It is extremely rare upon ores.

Reasons to Visit
This is the best place for mining and cave exploration in the game. It features huge amounts of ore, whether inside caves or out in the open, and ores all the way up to Iron can be visible outside of caves. These hills are also very steep, raising chances of fall damage and making it good for a nice, hardcore survival.

Good for a Base?
Sure! Just make sure it's nearby a tree-filled biome, since trees aren't the most common here. This biome can really help when you want ore, so when you need it, think about making a base here.

Forest
The Forest is a common biome featuring a large amount of Trees.

Temperature
Lush.

Unique Mobs, Items, and Resources
Sheep, Cows, most Passive Mobs.

Reasons to Visit
Well, you need Wood, so you should visit here if you have the chance! This is a biome filled with wood (mostly just Oak and Birch), and it's a great place to get it.

Good for a Base?
Yes. Especially when you're starting out, since there is so much wood. Just try to build it on the border of it and another biome, so you don't have to deal with the occasional Hostile Mob or having to clear out so many leaves.

Taiga
The Taiga is a relatively cold biome featuring Spruce Trees, Ferns, and notably, Wolves.

Temperature
Cold.

Unique Mobs, Items, and Resources

 * Wolves - While in most other versions they also spawn in Forests, in this version they spawn exclusively in this biome. Wolves are neutral, tameable mobs that come in both baby and adult versions. They can be tamed with a bone.
 * Spruce Trees - While not specifically exclusive to here, Spruce Trees are almost always only found here, and are the darkest wood type out there.
 * Fern - Ferns appear exclusively here. Large Ferns grow as well.
 * Podzol - A variant of dirt found exclusively to this biome. Podzol will randomly have mossy cobblestone on it as well.

Reasons to Visit
If you want Wolves or Spruce Wood, then this is the place for you. That's it's main purpose.

Good for a Base?
Sure! Wolves can guard your house, which is really helpful! Just note that you're going to be stuck with using only one type of wood, unless your house is nearby an area with different wood types.

Temperature
Lush.

Unique Mobs, Items, and Resources

 * Lily Pad - These are items used for decoration and creating bridges across water. They are only found here, and in large quantities.
 * Dark Water - The swamp biome has a darker and lusher water color to it.

Reasons to Visit
Well, good for you to take a swim in, and a great place for you to find Lily Pads, Vines, and Mushrooms. Also, if you need to quickly get Oak Wood, you can come here.

Good for a Base?
Why not. The large amount of nice resources make it a good place to have one. Just note that you won't have as much wood as you might want, and you'll be stuck with Oak Wood for the most part. However, swamp oak trees drop many more saplings than normal oak trees.

Temperature
Lush. (However, depending on what it cuts through, the temperature might vary)

Unique Mobs, Items, and Resources
Clay

Reasons to Visit
Not really much at all. You can go in here for a quick swim, but nothing specific you might want in this biome besides Clay, Sand, or Gravel.

Good for a Base?
Not really. The River itself gets in the way, and you'll probably have to climb a lot to get to where the wood's at, as there's not much wood down at the River biome.

Temperature
Snowy.

Unique Mobs, Items, and Resources

 * Snow - While not exclusive to here, it is found in the biggest amounts in this biome. Snow can be dug up with a Shovel to get Snowballs or make Snow Blocks.

Reasons to Visit
Come here for Snow, or raiding with Spruce Wood. Wolves might be found here, too.

Good for a Base?
All the wood you can really get here is Spruce Wood, so it depends. However, if you don't mind only using Spruce Wood, then this can be a good place for a home if you don't mind the snow or Wolves.

Temperature
Lush/Moderate temperature

Unique Mobs, Items, and Resources

 * Mycelium - Mycelium is the Mushroom Island's Dirt, which is purple-ish in color and spreads if place near other blocks. If you get Mycelium near a regular dirt block, the entire world could be taken over by Mycelium.
 * Giant Mushrooms - They can also be found in Roofed Forests, but are pretty much exclusive to here. If chopped down, they give off large amounts of Mushrooms.
 * Mushrooms - These are also obviously not exclusive to here, but like with the Giant Mushrooms, they are found in the biggest amounts here.
 * Mooshrooms - These are Cows with mushrooms growing on their back. They are red in color, and can give off Mushrooms if sheared or Mushroom Stew if you have a bowl. If you can get one to your house, you have an infinite food source, as you can have infinite amounts of Mushroom Stew in here.

Reasons to Visit
Well, if you love mushrooms, then this is the place to be. Plus, no hostile mobs spawn on these islands, so it's a good place to have a sanctuary.

Good for a Base?
No, unless you have resources prepared. It doesn't feature any Wood or even Grass, and there aren't really any mobs for food. Never make a base here, unless it's very close to or connected to some sort of wood-filled biome.

Beach
The Beach features Sand, Gravel, and the occasional group of Clay. It is often found when a Desert Biome reaches an Ocean Biome.

Temperature
Lush.

Unique Mobs, Items, and Resources
None.

Reasons to Visit
If you need Clay, Gravel, or Sand, this can be a nice place to stay. Otherwise from that, there isn't much reason to be here.

Good for a Base?
Depends. If you're near a Forest, Jungle, or anything of that sort, then yes. If not, then probably not. Beaches don't feature much wood, so you'll want one.

Jungle
The Jungle is a dense, lush biomes filled with trees, both thick and tall, Melons, Cocoa Beans, and much more.

Temperature
Lush.

Unique Mobs, Items, and Resources

 * Jungle Trees - These trees are found exclusively here, and are the best type of wood out there, so try to get at these trees when you can.
 * Ocelots - Passive mobs that run very quickly, away from the player. They were added and then removed, due to no Fish for taming. They have no drops and can scare away Creepers. Ocelots are currently not in Pocket Edition.
 * Cocoa Beans - Chocolate beans that can be used to craft Cookies and such. Kinda unhealthy, but tasty.
 * Melons - When destroyed, they create Melon Slices. They are only spawned in this biome and are very useful.
 * Vines - While not only spawned in this biome, Vines are most often found here and can be climbed to get to the top of those Jungle Trees.

Reasons to Visit
So many resources, it's ridiculous. Just come here for Jungle Wood, Cocoa Beans, whatever. But it's a great place to be, and it's great for a treehouse!

Good for a Base?
Yes/No. You have super tall trees and lots of wood, so why not build a tree house? Also, all those resources makes it a good place to live in, too. However, a major disadvantage is that Spiders may be abundant due to the fact that they spawn on leaves.

Birch Forest
A variant of the Forest biome that only has Birch Trees.

Temperature
Lush.

Unique Mobs, Items, and Resources

 * Birch Trees - Of course, they are not exclusive to here, but they are most common here.

Reasons to Visit
Just good for raiding with Birch Wood.

Good for a Base?
If you don't mind the Leaves and there only being one type of wood for you to use, then go for it.

Roofed Forest
Also called the Dark Forest, the Roofed Forest is an almost completely shaded in Forest variation with tall Dark Oak trees and Giant Mushrooms.

Temperature
Lush.

Unique Mobs, Items, and Resources

 * Dark Oak Trees - These Oak Tree variants are only found here.

Reasons to Visit
Well, if you want Dark Oak Wood, this is the only place you can get it. Also, it's the only place in the game besides the Mushroom Island to feature Giant Mushrooms. Lastly, it's good for mob hunting, as the shade allows mobs to easily spawn here, even during daytime.

Good for a Base?
Sure! You can mob hunt here, and get a bunch of mushrooms and wood, too! However, it's best you make a tree house here, since monsters and leaves can get in the way of your house on ground.

Cold Taiga
Now here's the real deal; the Taiga biome with Snow everywhere. Makes more sense the regular Taiga.

Temperature
Snowy.

Unique Mobs, Items, and Resources
None.

Reasons to Visit
Basically the same reasons as the Ice Plains; getting snow and wolves. Also, wood can be found more commonly here, making it better for a home than the Ice Plains.

Good for a Base?
Also the same as the Ice Plains; if you don't mind the Wolves, Snow, and there only being one type of wood, then go for it.

Savannah
A warm, vast biome with Acacia Wood and large amounts of grass. They are almost always found near a Mesa biome.

Temperature
Dry.

Unique Mobs, Items, and Resources

 * Villages - While not exclusive to here, they are found most commonly here. Read the page for the info.
 * Acacia Trees - Special trees that are often not straight. They spawn in this biome exclusively.

Reasons to Visit
For Acacia Wood and Villages, this is the place to be. Also, if you want large amounts of Seeds, then you should be here, too. Also, seeing one of these probably means there is a Mesa nearby.

Good for a Base?
Sure. Especially if you're nearby a village, since you can take your time with having to make a house if you're nearby one. Just note that you'll probably be limited to only using Acacia Wood.

Mesa
A Desert-like biome featuring Cactus, Dead Bushes, Red Sand, and Stained Clay of all kinds. Also, in a future update, Gold will be found here at any level, and it will have above ground Mineshafts.

Temperature
Dry.

Unique Mobs, Items, and Resources

 * Red Sand - They are only found here, so get them if you need it. Just red versions of Sand.
 * Clay - It is found most commonly here, but is not exclusive to here. Can be used to make Bricks.
 * Stained Clay - You can find various versions of it at any level here, whether above ground or underground.
 * Hardened Clay - Just like Stained Clay, it can be found at any level here.
 * Above Ground Mineshafts - Mineshafts, that hence their name, are only found above the ground. Much better to come in one of these than have to go explore underground and waste your time finding one.

Reasons to Visit
If you need Clay, come here and get as much as you want. It's got Hardened, Stained, and regular versions, all spawned naturally. You can also get Dry Bushes and Cactus here as well.

Good for a Base?
Yes if resources are provided. It has very little life and no wood, so you should only come here for the Red Sand and clay of all kinds. Not for making a base, unless you're near a Jungle or something.

Ice Spikes
The Ice Spikes is basically the Ice Plains Biome, but with huge tree-like ice spikes that release water when destroyed. It also features steep cliffs.

Temperature
Snowy.

Unique Mobs, Items, and Resources

 * Ice Spike Trees - These unique structures may release water when damaged.

Reasons to Visit
Mostly just for getting fun out of destroying the spikes, or getting snow. This is a better place for exploration than a regular Ice Plains biome, however, as it has more ore and is much more steep.

Good for a Base?
Sure! Better than an Ice Plains biome, as it might not have Wolves, but does have steep hills and huge Ice Spikes.

Mega Spruce Taiga
This biome is a unique, woods-style area, featuring wolves, tall and thick spruce trees, Podzol, and Mossy Cobblestone. A nice place to have a home, as well.

Temperature
Cold.

Unique Mobs, Items, and Resources

 * Podzol - A variation of Dirt that looks like Dirt, but is slightly different.
 * Mossy Cobblestone - Found naturally here, this is basically Cobblestone with Vines all over it, but actually isn't.

Reasons to Visit
If you need Podzol or Mossy Cobblestone, come here. Also, the trees are really tall as well, so you might want to try it out. Wolves can be found here as well, and these biomes feature a fair amount of caves.

Good for a Base?
Sure! It has tons of Wood and useful resources, and can be good for a typical log cabin-like home.
