Forest

The Forest biome is a common lush biome. It has a total of three variations, and is among the first biomes added to the game.

Description
The forest biome has a large number of oak and birch trees across its mildly hilly terrain. Lilacs, rose bushes, and peonies can also be found alongside the usual dandelions and poppies. The trees generate densely, but not normally dense enough to allow hostile mob spawning during daylight like the related dark forest biome. Wolves rarely spawn in forests, making this the only other biome aside from taigas where wolves can spawn. Lakes generate relatively frequently, and lava lakes that generate in forests can cause wide-spreading fires due to the density of flammable trees. Forests can generate in patches within other biomes, usually plains; these patches are typically only a couple hundred blocks in size, making forests potentially some of the smallest biomes. Forest is the most common biome in Minecraft.

Forests are one of the most preferred biomes for beginners, as they serve as an abundant source of wood and don't have too many dangers aside from the usual hostile mobs. Tamed wolves can help fight against hostile mobs, making them especially useful for when players lack resources for armor. The density of the trees, however, can lead to obstructed night vision and can get a beginner lost very quickly.

Variants
The main forest biome has two additional variants, for a total of three different forest biomes, excluding Dark Forests, Birch Forests and their variants.

Wooded Hills
Wooded Hills (known as ForestHills before 1.13) variants are similar to normal forests, though the terrain is hillier and generally more erratic, making it less suitable for shelter. Wolves may still spawn in the hills.

Flower Forest
The Flower Forest variant has less trees than the regular forest biome, but boasts countless numbers of flowers across its landscape. Every type of flower, except for sunflowers and blue orchids, generates in this biome; in fact, allium flowers only generate in this biome. The vast numbers of flowers makes this biome an excellent source of dye. The terrain here is somewhat more erratic than the regular forest biome, comparable to the wooded hills biome. Wolves do not spawn here, but rabbits can.
