The Release of a Captive-Raised Female African Elephant (Loxodonta africana) in the Okavango Delta, Botswana.

Evans K, Moore RJ, Harris S - Animals (Basel) (2013)

Bottom Line: Wild female elephants live in close-knit matrilineal groups and housing captive elephants in artificial social groupings can cause significant welfare issues for individuals not accepted by other group members.Although she did not fully integrate into a wild herd, she had three calves of her own, and formed a social unit with another female and her calf that were later released from the same captive herd.We recommend that release to the wild be considered as a management option for other captive female elephants.

ABSTRACT
Wild female elephants live in close-knit matrilineal groups and housing captive elephants in artificial social groupings can cause significant welfare issues for individuals not accepted by other group members. We document the release of a captive-raised female elephant used in the safari industry because of welfare and management problems. She was fitted with a satellite collar, and spatial and behavioural data were collected over a 17-month period to quantify her interactions with the wild population. She was then monitored infrequently for a further five-and-a-half years. We observed few signs of aggression towards her from the wild elephants with which she socialized. She used an area of comparable size to wild female elephants, and this continued to increase as she explored new areas. Although she did not fully integrate into a wild herd, she had three calves of her own, and formed a social unit with another female and her calf that were later released from the same captive herd. We recommend that release to the wild be considered as a management option for other captive female elephants.

animals-03-00370-f002: Distance to nearest neighbour when Nandipa was with wild herds and one or more of the released males. The figure shows means ± SE.

Mentions: Over the 17 months she was monitored, Nandipa spent 55% of her time with one or more of the released males and the wild males with which they associated, and 28% of her time with wild herds. Twelve percent of her time was spent alone, while the remaining 5% was spent with the Abu herd. Distance to nearest neighbour was not affected by season (F2,43 = 1.100, P = 0.343) or time post-release (F15,43 = 1.610, P = 0.139). However, it was affected by social grouping (t = −3.56, P = 0.004), being significantly smaller when Nandipa was with a wild herd than when she was with the released males (Figure 2).
