Tropical Grasslands Cameron V. Jessica S. 5th hour
Tropical Grasslands • Characteristics of grasslands: • Seasonal drought • Grazing of large herbivores • Periodic fires • High avg. temperatures • Low to moderate precipitation • Prolonged dry season (Miller, p. 136)
Savanna’s A tropical grassland is also know as a savanna, they are grasslands with very few individually scattered trees. The savannas are always found in warm to hot climates
Climate Characteristics • Average annual temperature: 18c • Temperature range during the year: 20-15c • Average annual precipitation : ~50.8 to 127 cm • The year consists of 6 to 8 months of rain and then a few months of drought

Geographic Location The orange areas are the Tropical Grasslands. They are found around tropical forests in Australia, India, Africa, and South America and some in North America.

Why these organisms + special adaptations • The reason that there is such a diverse animal population because there is plenty of grass, shrubs, trees to eat, and for most of the year there is water, except for 2 dry seasons. The herbivores are very fast to escape predators and some animals like the gazelle and the ostrich can reach speeds up to 80 mph. To make up for their lack of speed (except cheetahs) predators are very cunning, strong, and a lot of them hunt in packs. The Plants like the baobab tree hold extra water in their trunk, and lose their leaves to survive the dry season, and grasses leave only their roots because they have no where to hold extra water.
