Giraffes
Human Interactions
with Giraffes
Nearly 30% of Giraffe population has dropped due to:
Savannas have two sections of the seasons when it comes to rain. There is a rainy season in the summer with around 15 to 25 inches of rain and a dry season in the winter when their's only a couple of inches of rain The plants have to be able to survive the dry season/drought in the savanna. Some plants store water/energy in their roots or trunks & other plants have roots that go deep into the ground to reach the water underground.
Every day during the rainy season, the hot wet air rises off the ground and bumps into the cooler air above and turns into rain.
Food of Giraffe
Seed pods
Leaves and twigs of acacia, mimosa, and wild apricot trees
Sometimes grass (must stand in an akward position)
They also eat some fruit ocasionally like marula fruit
Giraffe Eco-System
Giraffes mainly live in sub-Saharan region of Africa (south of the Sahara dessert). The weather is usually between 20-40 degrees Celsius and it is very dry. It is very hard for giraffes to first find water.

ANIMALS
TREES
The trees in the African Savanna are generally 6-12 meters tall. These trees can be up to 30 meters tall, have a circumference of over 40 meters, and a diameter of 10 meters (at base of trunk). Some of these trees are:
Adansonia Digitata
This tree lives between 1'000-6'000 years old. It is shaped like a bottle and its trunk has over 120,000 litres within its tissues.
IN AFRICA THERE ARE APPROXIMATELY 100 SPECIES OF WILD BOVIDS (A MAMMAL THAT COMES FROM THE CATTLE FAMILY). THE AFRICAN SAVANNA HAS APPROXIMATELY 1/3 OF THE WORLDS FELINES (CATS): LIONS, LEOPARDS, CHEETAHS, THREE DIFFERENT SPECIES OF HYENAS, 3 TYPES OF JACKALS, & HYENA DOGS.
THE SAVANNA BIRDS ARE: THE OSTRICH, WEAVER PASSERINES, & VULTURES.
Acacia
Acacia are 1/2 of the trees that live in this eco-system and live a short life (about 15-30 years). There are more than 800 species of this kind of tree. Acacia Tortillis has an umbrella leaf shape and are giraffes favorite food.

Hunting:
African Hunters like the giraffe for its hide & hair. Also sometimes for its tough nutritious meat & the tail to make bracelets.
Groups of people who try to protect the environment (conservation groups) consider it a concern
Habitat Destruction:
Basically all the forms of habitat destruction reduce the amount of land available for giraffes. Some land is taken from human development like roads and houses, and some land is developed for raising crops or livestock. In some places, people cut down trees for firewood.
Relocation:
Not all humans have negative effects on giraffes. Humans making the effort to relocate animals to better habitats have helped keep the giraffe population in some areas.



Research:
One specie of Giraffe is called The Rothschild's Giraffe. In Kenya, their is a Rothschild's Giraffe Project where they research to help this specie survive. They've done research on habitat needs, social structure and behavior of the Rothschild's giraffe.


Water in the Savanna
A giraffe is a herbivore and will typically eat about 66 pounds (30kg) of food a day. Their foods are:
Food Webs
Natural Disaster
Man Made Disaster
