salt licks. Conservation status Because the Chacoan peccary is endemic to a formerly isolated region of South America, it is most vulnerable to human activity. Just as quickly as this species is discovered in an area, it disappears. Herd numbers are decreasing as a result of habitat loss and fragmentation. Their range is being quickly transformed into large Texas-style ranches. Hunting also continues, as well as an unidentified disease that has plagued the herds in recent years. A population has been established in North American and European zoos. Preserves have also been established in Paraguay, but are not highly enforced.
