Biomes
What is a Biome?
Biomes are large geographical areas that share similar characteristics such as flora, fauna and soil. These characteristics have adapted to live in that particular biome.
How do different biomes vary?
Biomes can vary from their landscape, climate, vegetation, soil, location and plant and animal species. For example deserts are hot, dry and don't get much rainfall where as forests are quite most areas which have large amounts of vegetation etc.

Australia's major biomes
- Wetlands and Rivers - Are under threat in many parts of Australia
- Savanna - Generally flat and have few trees and also minimal amounts of rainfall
- Sea grass meadows - 60+ known species in Australia. Sea grass meadows absorb a lot of nutrients
- Old-growth forests - Multi-layered and have few signs of human disturbance.
- Desert - Temperature extremes, can be referred to as the outback, can also be ice deserts as well as sand deserts.
Biomes in the Central African Republic
The African Savanna biome is tropical grassland and can also be described as a thorn bush savanna. The dry season occurs for more than seven months of the year which includes extreme heat and dry winds. Savanna has both a dry and a rainy season. Seasonal fires play a vital role in the savanna's biodiversity. In October, a series of violent thunderstorms, followed by a strong drying wind, signals the beginning of the dry season. Fire is prevalent around January, at the height of the dry season.This type of grassland biome can also increase the chances of grasing which turns grasslands into hot, dry deserts. This leads to restricted resources such as freshwater and moist soil. Although this biome provides large areas of land, due to climate change it can also make it difficult to produce good quality food and livestock.
This biome is used for food production in the C.A.R. because of the huge amounts of land available. Farmers benefit from this in many way because large pests do not live in grasslands which doesn't effect nearby farms and houses. Although grasslands provide lots of land for farming they also do have a down side. If the soil is over grazed, the grassland can turn into a dessert. This can effect farmers because the soil will be too dry and have no nutrients which wont benefit crops in anyway. this then plays an effect of food production and shortages.
