In 2022, 38 tortoises rescued from the illegal pet trade in Paraguay were imported to Argentina to be released in the wild. The Red-footed Tortoises underwent a lengthy quarantine in Argentina before their transfer to El Impenetrable National Park. After serious health screenings and acclimatizing in a pre-release area for several weeks, the first 10 specimens were released in 2022. This conservation strategy is called rewilding and seeks to recover healthy, complete, functional ecosystems by bringing back locally extinct species and supplementing threatened species. The rest of the group was released in different batches during the wet season of 2023.
During the pre-release period, the tortoises are held in semicaptive conditions, fed and provided with water. After acclimation, they are set free in their new environment, with newly released tortoises monitored on a daily basis through VHF transmitters. This initial monitoring stage, which lasts 30 days, allows evaluation of the initial adaptation to the wild of the tortoises. Observations include the shelters they use, activity, distance moved from previous locations, inhabited environments, and food preferences. After this initial stage, only five tortoises of the group will be monitored on a daily basis.
This thriving population is regularly monitored and found in good condition, feeding from native plants, fruits, carrion, snails, and mushrooms, and engaging in reproductive behavior.
