1 Tropical Savanna By: Kristin Maushart & Holly Reynolds

2 Geography

3 What factors determine the development of savanna vegetation?  Climate--including seasonality (if exists)  Soils— nutrient-poor, but either well or poorly drained  Fire— natural or (more commonly) human-induced  Human influences-- cutting, agriculture

4 Victoria Plains, Australia Trans Fly, Indonesia Kimberly, West Australia East African Savannas Climates www.runet.edu

5 Wildlife  Herbivorous  Herd Animals www.elephant-pictures.net www.gallery.search.yahoo.com

6 Wildlife ~Carnivorous ~Herds/Solitary http://www.bengaltigers.com/bigcats/lions.htm

7 Plant Life  Cold temperate steppe: growing season.  Cold temperate steppe: dormant season. www.managingwholes.com

8 Plant Life  High rainfall tropical savanna: growing season.  High rainfall tropical savanna: dormant season. www.managingwholes.com

9 Fire  Most types show evidence of frequent fire  Morphological “adaptations” to withstand it

10 Human Influences  Conversion of savanna/forest to agriculture, grazing land; charcoal extraction  Higher ground-level temperatures (“albedo”) by loss of vegetation cover  Increased erosion, soil compaction  Reduced soil nutrients
