A '''biome''' is a biotic area with homogeneous features, characterized by distinctive [[plant]]s, [[creatures|animal species]] and [[climate]]. A biome will also contain only one set of stone layers, though these usually expand beyond a single biome. Your [[dwarves]] will find different resources depending on which biomes they select when starting a fort.

== Biomes in Dwarf Fortress ==
+
Biomes are important when choosing a fortress location in order to understand your [[surroundings]]. Individual biomes, which form at least one map-tile of your embark location, can be cycled with the {{Key|F#}}-keys; for example, an area with 3 biomes present can be cycled using {{Key|F1}}, {{Key|F2}} and {{Key|F3}}. The selected biome will be highlighted with flashing Xs on the Local Map, and the biome's information will be displayed on the right side of the screen. ''(See the [[Indecisive%27s_illustrated_fortress_mode_tutorial|illustrated guide]] for more detail).''

Biomes in Dwarf Fortress are relevant when you are choosing a fortress location. The individual biomes which form at least one tile of your plot can be cycled with the F-keys, one for each biome in your plot. Your selected biome will be highlighted with Xs on the Local Map, and the biome's information will be displayed on the right side of the screen.
+
== Understanding Biomes ==
  
 +
Selecting different Biomes gives you some ability to influence the difficulty of your game.  Each biome has a different set of resources; the availability of [[tree]]s, [[sand]], certain [[plant]]s or [[animal]]s, and sometimes [[water]] is specific to a particular biome, and different biomes may have different stone layers containing [[flux]], [[coal]], useful [[ore]]s, or a high chance of [[magma]].  [[Mountain]]s have a lot of [[ore]] and some exclusive [[underground river|features]], but no [[soil]].
  
−
== How to Utilize Biomes ==
+
Generally it is advantageous to plot your embark [[location]] at the convergence of multiple different biomes, the more the better (within reason) - which is made easier if you enlarge your starting embarkation area.  However, it is not usually too hard to find three or four biomes using the default size.
 +
* ''Note: Making the starting plot larger will slow your game down considerably; likewise, a small embark area can dramatically increase framerate.''
  
−
Biomes present an easy way for you to provide a variety of resources to your fort. As your starting plot stretches over varied biomes you will have access to the unique resources they each may provide. Generally it is advantageous to plot your embarkation at the convergence of 3 seperate biomes (4 or more if possible - which is made easier if you enlarge your starting plot).
+
By making use of several biomes you can provide more resources for your fort. Making sure one of your biomes contains either a broadleaf or conifer [[forest]] will provide you with an ample supply of [[tree]]s, even if the rest of your plot extends into badlands and [[desert]].  You might get wood from a forest, ore from a mountain, and flux from [[hills]] that just happen to have a flux layer; many other permutations are possible.
  
−
By making use of the 3 seperate biomes you provide more resources for your fort, especially if they are unique biomes. For instance: making sure one of your plots cover a broadleaf or conifer forest will provide you with an ample supply of trees, even if the rest of your plot extends into badlands and desert.  
+
Any biome can have any set of [[surroundings]]; for example a [[glacier]] could be [[haunted]], [[wilderness]] or [[mirthful]]. However, a named region (which is a contiguous area of one category of biomes, such as forests or wetlands) will be either good, neutral, or evil.  It is not uncommon to see a large mountain range with one alignment and a few mountains, disconnected from the main mountain range by a single region tile, with a different alignment.  Therefore, the more biomes you have, the more likely it is to have several alignments, if so desired.
  
−
Surroundings are not directly linked to biomes (i.e. Glaciers can be Haunted, Wilderness or Serene).
+
If your plot contains only [[ocean]], [[lake]] or [[mountain]] biomes you will not be able to embark. The dwarves would have difficulty parking their [[wagon (embark)|wagon]] on water, while mountains are too barren and remote to reach.
−
 
 
−
If your plot is completely encompassed by an Ocean, Lake or Mountain biome you will not be able to embark.
 
  
 +
The exact process is unknown, but no relation has been found between biomes and the stone layers that lie deep beneath them in the same area block.

This article is about an older version of DF.

A biome is a biotic area with homogeneous features, characterized by distinctive plants, animal species and climate. A biome will also contain only one set of stone layers, though these usually expand beyond a single biome. Your dwarves will find different resources depending on which biomes they select when starting a fort.

Selecting a biome[edit]

Biomes are important when choosing a fortress location in order to understand your surroundings. Individual biomes, which form at least one map-tile of your embark location, can be cycled with the F#-keys; for example, an area with 3 biomes present can be cycled using F1, F2 and F3. The selected biome will be highlighted with flashing Xs on the Local Map, and the biome's information will be displayed on the right side of the screen. (See the illustrated guide for more detail).

Understanding Biomes[edit]

Selecting different Biomes gives you some ability to influence the difficulty of your game. Each biome has a different set of resources; the availability of trees, sand, certain plants or animals, and sometimes water is specific to a particular biome, and different biomes may have different stone layers containing flux, coal, useful ores, or a high chance of magma. Mountains have a lot of ore and some exclusive features, but no soil.

Generally it is advantageous to plot your embark location at the convergence of multiple different biomes, the more the better (within reason) - which is made easier if you enlarge your starting embarkation area. However, it is not usually too hard to find three or four biomes using the default size.

  • Note: Making the starting plot larger will slow your game down considerably; likewise, a small embark area can dramatically increase framerate.

By making use of several biomes you can provide more resources for your fort. Making sure one of your biomes contains either a broadleaf or conifer forest will provide you with an ample supply of trees, even if the rest of your plot extends into badlands and desert. You might get wood from a forest, ore from a mountain, and flux from hills that just happen to have a flux layer; many other permutations are possible.

Any biome can have any set of surroundings; for example a glacier could be haunted, wilderness or mirthful. However, a named region (which is a contiguous area of one category of biomes, such as forests or wetlands) will be either good, neutral, or evil. It is not uncommon to see a large mountain range with one alignment and a few mountains, disconnected from the main mountain range by a single region tile, with a different alignment. Therefore, the more biomes you have, the more likely it is to have several alignments, if so desired.

If your plot contains only ocean, lake or mountain biomes you will not be able to embark. The dwarves would have difficulty parking their wagon on water, while mountains are too barren and remote to reach.

The exact process is unknown, but no relation has been found between biomes and the stone layers that lie deep beneath them in the same area block.
