  • Composed of multiple colored hardened clay.
  • Dead bushes spawn in this biome.
• Redwood Forest biome.

    • Currently obtained only by the silk touch enchantment.
  • Contains dirt blocks that do not allow grass to grow.
    • They have a data value of 1.

Improvements & Changes

• Changes to oceans.
  • Oceans are smaller and take up much less of the map.
• Biomes have been put into four main categories: snow-covered, cold, medium, and dry/warm. Biomes will attempt to avoid getting placed next to a biome that is too different to itself.
• Most biomes have uncommon/rare variations.
  • Non-snowy taiga variation.
• Spruce Trees will generate in Extreme Hills biomes or a variant of them.
• Snow may now generate depending on Y level, with noise variation.
  • Biome dependent.
