caused issues. Kruger had successfully rebuilt the African elephant population and other animal preserves were still struggling. SO it was decided to move elephants from Kruger to other preserves to strengthen the populations elsewhere.
It was easier to move the smaller females and males so a lot of young bulls were put in a new environment, Pilanesburg in the case of the story, and ran amok without the guidance and discipline offered by older males. That is when they decided to bring in some of the bigger males, despite the difficulty to transport them from Kruger.
