Located in northern Tanzania, East Africa, the Serengeti national park is home to the biggest herds of grazers in the world, other herbivores, predators, carrion feeders and over 500 species of bird While it was created by natural forces, the plains are maintained by the actions of billions of animals. Migrating herds trample and crop the land, leading to fresh shoots and renewal of the grassland. Smaller creatures also lend a hand. Termites recycle the soil with their digging The mounds of earth they leave, provide homes for snakes, mongooses and mice.
Predators hide behind them to spy on prey. Dung beetles dig tunnels into the soil to store refuse for their larvae.
This helps fertilize the soil and keeps the grasslands healthy.
