In the heart of the Pantanal wetlands, there's a region so remote very few humans ever get there. Because of this, the ecosystem is pristine and the wildlife that lives here hardly knows any threats, except from other animals. The vast landscape is dotted by ten thousand lakes flush with aquatic plants, hundreds of acres of forests are filled with tall palm trees and large patches of savannah make this region, known as Nhecolandia, the perfect habitat for a thunderous herd of three hundred white-lipped peccaries. Scientists track the sub-herds to learn more about their behaviour and social organization.
