Biomes terrian
Climate
The savanna climate has a temperature range of 20° - 30° C. In the winter, it is usually about 20° - 25° C. In the summer the temperature ranges from 25° - 30° C. In a Savanna the temperature does not change a lot. There is an annual precipitation of 10 to 30 inches (100 to 150 cm) of rain. From December to February hardly any rain falls at all.

Humans' Impact
Humans' Impact
1) In savannah,there's limited trees. One way humans positively influence the biome is they create biomes,by slashing the vegetation and burning the debris . This agricultural method is known as the Slash-and-Burn agriculture. The purpose of doing this is the soil will be more healthy and the seed is preserved.
Buried seeds sprout
The biome becomes a mature or recovered forest with a variety of living forms

2) Increasing more fires can spread and damage the soil.
Humans in the past has negatively deteriorated the savannah biome environmental landscape. Since vegetation is destroyed,some animals has to rely on their prey to obtain their energy,but this a struggle for animals because human practices such as hunting declined the number of life in the biome for the animals flesh.
For example, elephants for many years were shot for the tush and lions for their fur.

3) Humans impacted the environment in a negative way by taking much of the land to input infrastructure and for industrialization.
Infrastructure: water dams
Industrialization: factories, businesses

Interesting Fact
Biome facts
The savannah has many unique factors like it's climates,animals and the beautiful features in the forest.
1) As you know the world's largest tropical savannah is the Australian Tropical savannah,which has dense grasses and spread with varieties of trees that survive in the dry-hot weather. Vegetation that mostly inhabit in this area is the Red Oak,Acacia and Manketti tree.
2) The climates in a savannah are dry and rainy. These climates occur seasonally at an extreme level.
3) Savannahs are near the equator. Countries like Africa,India and Australia are places where biomes extensively are inhibited.
4) In the Australian savannah, Marsupials dominate among the animals. They are mammals.
5) The Acacia tree is the most common tree,which produce human gum Arabic- are polysaccharides found in the woody elements of plants or in the seed coating, which is used as a stabilizer in the food industry and is a key ingredient in other industries.
