Biome Classification

There are two major bases of classifying biome.

[A] On the basis of climate with special emphasis on availability of moisture –

According to this basis biomes are determined by the degree to which moisture is available to plants in a scale hanging from abundant (forest biome) to almost scarce (desert biome).

But within each biome, conditions of temperature are vastly different from low to high altitudes and low to high latitudes.

Consequently there is a need to sub-divide each biome in to further sub-types.

[1] Forest biome

[2] Savanna biome

[3] Grassland biome

[4] Desert biome


[B] On the basis of climate and vegetation

This classification argues that there is a close relationship between the world distributional patterns of plants and animal species and the climatic types of the world.

Thus, based on this relationship the world has been divided into different biome types.

The vegetation is the most dominant component of the biomes.

As the vegetation and climate have intimate relationship the world is divided into various types on the basis of climates.

Further, these climate based biomes are divided into various sub-types on the basis of vegetation.
