Transcript of Savanna Biome Project

Welcome to the Savanna Biome! Abiotic Features Weather
The average day during the winter-dry season is cool, but never gets cold. The summer-rainy season is humid and very wet. Climate Soil In the summer-wet season, the soil in the tropical grassland tends to be
very fertile due to constant grazing of large herbivores. The animals also leave behind
nutrients and the grasses and small shrubs replenish. Biotic Features Dominant Plants Jarrah Tree
-Long and deep root system that allows it the ability to pull up underground water during a drought
Umbrella Thorn Acacia
-It has “taproots” that can reach up to 115 feet underground and a second set of roots just underground that can be up to 2 times the area of the overhead canopy Baobab Tree:
-its loses its leaves 9 months out of the year and holds all of its water inside of its trunk
the trunks can be anywhere from 22 to 36 feet around and are able to hold up to 120,000 liters of water.
-It can live for thousands of years Dominant Animals African Wild Dog
-The African wild dog lives in grasslands, savannas, and open woodlands of eastern and southern Africa. The African wild dog is the largest dog in Africa, and the only member of the Lycaon genus.The African wild dog's scientific name literally means painted wolf. Emu
-The largest bird that inhabits the lush, grassy fields of Australia is the emu. Adults are about 5.7 ft. tall and weigh about 110-120 lbs. It has medium size wings, but it can't fly! African Elephant
-There are two species of elephants in Africa; the savanna elephant and the forest elephant, (Loxodonta cyclotis). The savanna elephant's habitat is usually savannas or grasslands. They are herbivores, and feed on grasses, fruits, tree leaves, bark, shrubs, and vines. Value to Humans:
- the tropical savanna is filled with biodiversity
-many plants found only in the tropical savanna are used for making medicines or are used for ingredients in things such as soda.
-savannas have many natural resources that humans use such as minerals, precious metals, limestone, and diamonds.
Unique Features Frequent fires are caused because of lightening during wet season.

There are 3 types of grasslands. Tall grasslands have very tall grass and they get 30 inches of rain a year. Mixed grasslands have grasses that are around 2 and 3 feet high. Mixed grasslands get 15 to 25 inches of rain per year. The last kind of grassland is short grasslands. This type of grassland is almost a desert. It has very short grass and only receives 10 inches of rain each year. Grasslands are usually called the transitional biome. Transitional biome means that grasslands are usually found between deserts and forests. It would become a forest if grasslands received more rain. If it received any less rain, it would be a desert. The End!
