SPECIES ID ‒ MAMMALS | RESEARCH PROJECT Black rhinoceros (Diceros bicornis), commonly referred to as ‘black rhino’, have been relentlessly persecuted since the 19th century and there are only about 5 000 animals remaining today. Ruthless poaching across Africa, and presently in South Africa, threatens the survival of the species on a global scale. South African National Parks “The biggest challenge is ‘trying to provide advice on both (SANParks) has established a Black Rhino Guardian Programme in theto best manage expanding populations in fenced reserves how Kruger National Park, whichwithin South Africa, while simultaneously educating people on hosts the largest population of black rhino in alarming pan-African decline facing elephants’.” the the country. This multidisciplinary programme draws support from Scientific Services, Ranger Services, K Air Services and Veterinary Wildlife Services to enable the best management and protection possible for the species. ruger is home to For 20 years, Elephants Alive, one of southern the Hoedspruit-based NGO, has Af rica’s largest been studying the elephants of f ree-ranging the Greater Kruger to ensure their elephant survival, and to promote harmony populations. with humans.

These last two activities are undertaken in collaboration with Cambridge University. Our research is helping us to understand the importance of the oldest bulls in elephant society, sadly deemed by trophy hunters to be ‘beyond their prime’ and by poachers as their most lucrative targets because of their large tusks. We have watched these long-lived old males teach, lead and discipline Collared elephant ‘Classic’, about 45 years old.

We have focused our attention on monitoring and naming mature bulls because much less is known about male elephants. Males can also be more at risk of being involved in human- elephant conflicts such as crop raiding – and of course big bulls are top of poachers’ hit lists.

SPECIES ID ‒ MAMMALS | RESEARCH PROJECT the younger bulls. Elephants revere their elders, relying on their wisdom to teach them their ways – something we humans sadly seem to have lost. Our elephant ID studies are the longest and most consistent for all of southern Africa. This long- term research is providing fundamental information for elephant management and protection, informing SANParks, conservation bodies and private landowners on seasonal movements, the sustainability of trophy hunting in some private reserves, and impact on vegetation. Worryingly, it is now also used to identify poaching hotspots. Michelle re-collaring ‘Classic’. “Our elephant ID studies are the longest and most consistent for all of southern Africa.

SPECIES ID ‒ MAMMALS | RESEARCH PROJECT “As well as identifying and studying the movements of elephants, Elephants Alive also works hard to minimise human-elephant conflict.” As well as identifying and studying the movements of elephants, Elephants Alive also works hard to minimise human-elephant conflict. One of the biggest issues is elephants damaging large trees – particularly in the private reserves bordering Kruger, where there are more artificial waterholes, which attract more elephants in times of drought or during the dry season when they are primarily browsers. Some private landowners are calling for elephants to be shot to reduce tree damage. Elephants Alive outreach work at schools. Elephants bypassing a tree with beehives.

Named as one of “the ten most inspiring women in South Africa” by Culture Trip in 2017, Michelle is one of conservation’s unsung heroes. When asked what Elephants Alive’s biggest challenge is, Michelle explains that the biggest challenge is “trying to provide advice on both how to best manage expanding populations in fenced reserves within South Africa, while simultaneously educating people on the alarming pan-African decline facing elephants”.
