Filled with freshwater lagoons and reservoirs, the Iberá Wetlands connect diverse forests, marshlands, and grasslands, which were severely deteriorated during the 20th century, with a devastating loss of wildlife, including keystone species like the giant otter and the jaguar, and a loss of traditional knowledge in the communities. By reintroducing Iberá’s keystone species, we can restore the region’s natural processes and the unique culture that evolved with them.
