Tropical Grasslands By: Caitlin Stadtler
What is the Climate? • Warm Climate– Hence the name Tropical • High Temp: 86 degrees Fahrenheit • Low Temp: 68 degrees Fahrenheit • 2 Seasons • Summer: Wet Season • 20-50 inches of rain per year • Winter: Dry Season
What is the Landscape Like? • Grassland with scattered trees • Mostly grasses and forbs (small leaved plants) • Soil: porous, rapid drainage of water
Types of Savannas • Climactic Savannas: result from climactic conditions • Edaphic Savannas: caused by soil conditions and are not entirely maintained by fire -- these can occur on hills or ridges where the soil is shallow, or in valleys where clay soils become waterlogged in wet weather. • Derived Savanna: result of people clearing forest land for cultivation
Common Names • Savanna • Shrub land • Prairie • Steppe
Where in the World do we find Tropical Grasslands? • Mostly Australia and Africa • Found between tropical rainforests and deserts • Found in a wide ban on both sides of the equator
What Kinds of Animals? Mammals: Hedgehog, Aardvark, Elephant, Naked Mole Rat Birds: Ostrich, Pigeon, Golden Eagle, Zebra Finch Insects: Painted Lady, Desert Locust Reptiles: Crocodile, Frilled Lizard, Pythons, River Turtle
What Kinds of Plants? • Orchids • Grasses and Sedges • Hat Thrower Fungus
Animal Adaptations • Thrive during the Rainy Season • But, in the Dry Season, water becomes difficult to find • Large mammals and birds migrate in search of water • Fleeing from Fires in the Dry Season
Animal Adaptations (2) Elephants: • Baobab Trees: Store water in their trunks • Elephants have the size and anatomy to be able to open up the large trunks and suck water from them • Thus, they do not need to migrate • Although they sometimes do
Plant Adaptations • Overall, plants adapted to grow fast when there is adequate water supply and to store water for use during long periods of drought • Grass: turns grown when there is lack of water to limit water loss • Store moisture and liquid in roots • Baobab Tree: only grows leaves in wet season • Limits water loss
Plant Adaptations (2) • Acacia Trees: has developed ability to grow long/deep roots which allows it to reach to deep water • Fire Resistant • Thorns – protect them against predators • Symbiotic Relationship with Stinging Ants • Alkaloid Chemical – protects Acacia trees from grazing giraffes
Human Impacts • Positive!! (+) • The creation of National Parks: protect from endangered species, allow animal populations to thrive • Negative.. (-) • Tourist presence can be hindering to the animal populations • Lion Hunting • Poaching slaughtering animals • Illegal residents kill over 40,000 animals a year
