Elephants rewilded in South Africa exhibit wild behavior after five years

Eleven elephants, once held captive for tourism and entertainment, have been successfully rewilded in South Africa, displaying behaviors akin to their wild counterparts after five years. A study published on July 29, 2026, in the journal PLOS One, tracked these elephants after their release into four fenced reserves. Led by researchers from the Elephant Reintegration Trust of South Africa, this project highlights the resilience of elephants and the potential for successful rewilding initiatives. The findings indicate that these elephants have adapted remarkably well to their new environment, raising hopes for the future of captive elephants.

The historical context of this study reveals the challenges faced by elephants in captivity. Many elephants in South Africa were captured for commercial purposes, leading to a life of confinement that can result in psychological trauma. The project aimed to assess whether these elephants could regain the instincts and behaviors typical of wild populations. Over the five years, the researchers conducted thorough observations, monitoring the elephants' actions and stress levels through non-invasive methods, such as analyzing dung samples for stress hormones.

On the ground, the rewilding effort involved meticulous planning and execution. The team observed each elephant for three-week stretches annually, looking for signs of stress or abnormal behavior. This careful monitoring was crucial in determining how well the elephants adapted to their new surroundings. The researchers noted that while some elephants displayed signs of elevated stress hormones, all readings remained within healthy ranges, suggesting that the rewilding process was largely successful.

The project underscores the importance of tailored approaches to rewilding, considering the individual personalities of the elephants. The broader implications of this study extend beyond the specific animals involved. The successful rewilding of these elephants contributes to conservation efforts and highlights the potential for restoring wildlife populations. It also serves as a reminder of the psychological impact of captivity on elephants, emphasizing the need for improved welfare standards in facilities that house them.

The research suggests that with proper care and attention, elephants can overcome their past traumas and thrive in natural settings. Looking ahead, the findings from this study pave the way for future rewilding projects and conservation strategies. The success of these 11 elephants demonstrates the possibility of reintegrating formerly captive animals into the wild, encouraging other conservationists to explore similar initiatives. As more elephants are rewilded, the knowledge gained from this project will be invaluable in shaping best practices for the rehabilitation of captive wildlife, contributing to a healthier ecosystem and a brighter future for elephants in South Africa and beyond.
