  6. Herbivores of Savanna They all had to adapt to having plants with no water.

  7. Plants in the Savanna • The Curcuma Hides when it is growing. • The Liatris scariosa var. nieuwalndii can live with well-drained soils.

  8. Plant in the savanna cont. • Shrubs have to be able to grow with no water. • The Camassia quamash is able to grow with little amounts of water. • Death Camas have to grow with no water.

  9. Carnivores in Savanna Hibernate during the winter. Will migrate for food.

  10. Description of Savanna • A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome.

  11. Rainfall • Savannas get all their rain in the summer months. • 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.

  12. The threat in Savanna • 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.

  13. The benefits of Savanna • 1) To protect and provide habitat for migratory birds - Savannas provide habitat for over 100 species of birds. Brown thrashers, blue-winged teal, yellow warblers, and bluebirds make colorful additions to the savanna landscape • 2) To protect and provide habitat for threatened and endangered species • 3) To support a natural diversity of plants and animals on refuge lands - Savannas support a wonderful variety of living things. White-tailed deer, wild turkeys, wild lupine, mourning cloak butterflies, and the eastern hognosed snake all make their homes on Necedah's savanna habitats.

  14. Wetlands in savanna • The tropical Savanna has many wetlands
