The Chaccoan peccary is an endemic species of Gran Chaco, the second largest forest in South America. The peccary is a pig that is threatened with extinction by the degradation of its habitat, hunting, and the diseases that fall on it. It plays an important ecological role in the Gran Chaco. It feeds mainly on cacti and roots, so by tasting them, it spreads the seeds planted and contributes to the well-being of the ecosystem. The international organization Edge of Existence is responsible for monitoring the species and raising public awareness of its vulnerability.
