Biome/Before Beta 1.8

In Java Edition Beta 1.8, Legacy Console Edition TU5, and Pocket Edition Alpha 0.9.0 biomes received a major overhaul, removing and changing many biomes.

Biome types
Before the Adventure Update, biomes were much smaller, sometimes smaller than a chunk, and less distinct.

Biome placement was controlled by temperature and rainfall values, allowing interface biomes and making it nearly impossible to generate desert near taiga or rain forest near tundra while making transitions from biome to biome smoother. Height variation was less dependent on biome type, allowing cliffs and mountains to generate up to 128 y-axis in any biome (new versions only allow tall mountains to spawn in extreme hills and hill/mountain variations). Tall grass was also much less present in pre-1.8 worlds (except in the "Plains" and "Rainforest" biomes).

There were 13 biome types: 10 in the Overworld, 1 in the Nether, and 2 unused ones that are in the code but aren't encountered in normal play. These biomes were added in Java Edition Alpha 1.2.0 and relatively few changes undergone to these biomes other than the introduction of birch and spruce trees in Beta 1.2 (which allowed for new chunks to have birch trees generate in forests and spruce to generate in taiga in place of oak trees), the level file format being changed to Scaevalus' MCRegion in Beta 1.3, desert biome borders being rotated due to then not lining up in Beta 1.4, and the introduction of tall grass and ferns in Beta 1.6 test build 3, so obviously those characteristics shown below don't apply to versions before they were introduced. Grass and foliage colors were determined by the noise generated temperature and humidity values, rather than from the biomes directly, so there can be many different grass and foliage colors for one biome. Once the game gets the temperature and humidity values for pulling grass and foliage colors, it uses said values to grab colors from /misc/grasscolor.png or /misc/foliagecolor.png, and applies it to the uncolored grass or leaves.
