Grasslands Praire and Savannah

Kesauntee Cole 3 rd period project

Savanna

Savanna grasslands are found between tropical rainforests and desert. This includes areas such as Central Africa (Kenya), America and The North and East of South America (Brazil). Savanna is similar to grassland but with scattered trees. These areas have seasons: cool and dry, hot and dry followed by warm and wet.

Abotic factors

Abiotic Factors: Weather (Winters are dry and cool, summers are humid, hot and wet), Climate (Warm year round about 70 degrees), Precipitation (Can go through droughts, but not as dry as a desert, 15-25 inches during wet season), Soil (During the dry season it is infertile), Sun, Wind, Air

Warnings

Major threats to savanna biome

Savannas are amongst the oldest ecosystems used by people. Homo sapiens evolved in a savanna environment in East Africa about one million years ago. Anthropologists believe that these human populations existed by hunting wildlife and gathering plant materials. The Australian Aborigines are one of the traditional savanna hunter-gatherer cultures that still exist (Solbrig 1993).

Savannas land use currently includes fully nomadic pastoralism, semi-nomadic pastoralism, subsistence cultivation with no cash crop, and cash crop cultivation (including ranch, estate and plantation farming). In addition to food, fibre and wood production, savannas are also used for mining, national parks, tourism and urban developments.

Human usage of the savanna biome is increasing, which can lead to degradation of vegetation and soil resources, resulting in nutrient losses and shifts in water balance and availability. Brazilian cerradão contains over 800 species of trees and shrubs alone; approximately 40% of the cerradão and llanos has now been cleared or altered for agricultural uses with crops such as coffee, soybeans, rice, corn and beans.

Weather report

average precipitation in the Australian and the Africa savanna during the wet season is around 15 to 25 inches. Only rain falls in the Australian Savanna, there are no other forms of moisture. Most of the rain falls during the wet season.

Threats

Endangered Species

Black Rhino



The black rhino is one of the most endangered animal in the world--there were fewer than 3,200 in the world in 2001, most of which live on wildlife preserves. Even there, poachers kill them for their horns, which some people believe have medicinal value.
