Savanna

The savanna is a vast ecosystem comprising about a third of the world's land area, characterized by extensive grasslands interspersed with scattered trees. This environment is home to the most diverse large mammals on Earth, including herbivores like gazelles, zebras, and giraffes, as well as carnivores such as lions, leopards, and hyenas.

Human Impact

Poaching has lead to many animal species being endangered and even close to extinction
People setting fires or not putting them out properly
Ranchers raising native (Savanna) herbivors for meat instead of cattle
Fences put up disrupt animals migrating for food and water
Increasing population means more domestic animals graze in the Savanna

Vegetation

Thorny Acacia and Water Storing Boabab are some of the few species of trees that can survive the devastating dry seasons
Grass grows rapidly during rainy season and then dies back to drought resistant roots during dry period
Grass is sharp and bladed to protect from animals. Only some can eat it
Trees have long 'tap root' to reach water underground

Animals

Adaptations
Burrowing animals are protected from predator and fires as well as to avoid heat
Nocturnal animals hunt at night when less predators lurk around
Leopards have strong jaws that can crush skulls in a single bite
Cheetas can run very fast (up to over 110 km/h) to catch prey
Giraffes have long necks to eat from taller trees
Many have long wings or long legs for migration
Most diverse large mammals on Earth
Carnivors include Lion, Leopard, and Hyenas
Hebevors including gazells, Wilderbeasts, Zebra, Rhinos, Giraffe, Snakes, Carcal, Emu, Mongosse and Koala

What/Where

Warm all year around with rainy season during summer and dry season during winter
Mostly located in South America, Africa and Austrailia and found between rainforests and deserts around 30'N and 30'S
The Savanna is an ecosytem that makes up roughly 1/3 of the world's land with large areas of grassland and scattered trees
