Elephants boost tree losses in South Africa's largest savanna reserve

Protected areas, such as nature reserves and national parks, play a crucial role in sheltering wildlife, such as African elephants, from hunting and habitat destruction. But it's important that conservation managers understand how the vegetation in these natural protected zones is affected by the population growth spurred by this animal safeguarding. New remote sensing research shows that elephants are one of the leading causes of fallen trees in South Africa's Kruger National Park.
