For many years, Opwall has been working with a project called Space for Elephants Foundation in KwaZulu-Natal to provide research supporting responsible elephant population management. Together we have monitored the behavioural changes of a large herd of elephants in the Pongola Reserve following the vasectomies of the adult bulls. Parts of this reserve were subjected to huge grazing pressure, leading the elephants to take the matter into their own hands by traversing around the fences at the local dam and into a neighbouring reserve – Royal Jozini Big 6 in Swaziland. Behavioural data is currently being collected on the elephants in this new home, giving our researchers the unique opportunity to compare behavioural data from the same herd in two very different reserves. We are also monitoring changes in vegetation and herbivore distribution following this sudden change in grazing pressure in both Pongola and Royal Jozini Big 6.
