To Emiliano Donadio, the foundation’s scientific director, the release not only is crucial to rebuilding Iberá’s ancient ecosystem, but is a scientific experiment that will provide a rare glimpse of how the return of one of the world’s largest carnivores could transform an ecosystem. By the end of this year, conservationists hope to install one of the final missing ecological pieces-an apex predator-with the release of the jaguars. Because of the region’s now-protected status and the reintroduction of locally extirpated species to reconstruct ecological communities, the area is thriving with pampas deer and marsh deer, capybaras, caimans, and diverse bird and insect life. Now, wildlife is making a comeback in Iberá, thanks to an ecological restoration effort spearheaded by the nonprofit Rewilding Argentina Foundation. People killed off native predators to protect livestock, and many species were decimated to satisfy a burgeoning market for fur, leather, and feathers. Once a pristine habitat, the region has lost much of its wildlife since the early 20th century, when ranchers moved into the area. Three adults and the two-year-olds Amarí and Mbareté currently live in an enclosure on San Alonso, a patch of high ground in Iberá’s patchwork of flooded wilderness, lagoons, jungle, and grasslands. 3767-3774., doi:10.1242/jeb.The jaguars don’t know it yet, but soon they’ll be free to roam Argentina’s Iberá wetlands, becoming the first apex predators to do so in a century.
