The elephant population in Pilanesberg, South Africa.

What should be done with a herd of marauding elephants? This was the problem recently confronting officials at Pilanesberg National Park in South Africa. A number of orphaned male elephants had been transported to the park in order to provide them with a safe and nurturing environment. However, this step to protect the elephant population soon threatened another endangered species.

The young elephants had entered musth, like puberty, a state of heightened hormonal activity and increased aggression. The elephants went on a killing spree, slaying almost 40 rhinoceros—including incredibly rare black rhinos. The park officials did not want to kill the young elephants, but they could not afford to have any more rhinos slaughtered.

Oddly enough, the solution to this disastrous situation was to bring more male elephants into the park. This time, however, they were full-grown bull elephants. In almost no time at all, a previously impossible hierarchy had been established, and the orphaned males fell right into place. As of yet, no rhino killings have been reported.  The Pilanesberg story has a positive ending, but many elephants are not as lucky. The elephant population in Africa has been drastically reduced by loss of habitat to cultivation and urbanization, and many have been orphaned by poachers cashing in on the ivory trade. Some biologists believe that if elephant numbers continue to drop, it will soon be impossible to save the species.

Elephants are amazing creatures. As well as holding the title of "largest land animal," they are also among the most intelligent. An elephant has 150,000 muscle units in its trunk, can swim long distances without tiring, walks almost silently despite weighing about 7 tons, can travel up to 6,000 miles in a year while searching for food, and can live 60 years. Full-grown elephants have no natural enemies, other than humans. Eating 165-330 pounds of food a day, an elephant can clear thick brush into open savannah in no time, creating an open habitat for other animals. Several tree species rely almost solely on the elephant to scatter their seeds. If the elephant were to disappear, these life-forms would bear the consequences.

With only 2 elephant species left out of 600, the danger of extinction is imminent. If the population in any particular area drops below 100 individuals (as it has in several parks), that population is virtually doomed, having entered an “extinction vortex.” With fewer reproductive males and females being born continued inbreeding leads to genetic deterioration. The numbers begin to drop, and the cycle continues until the population completely dies out. Evidence of this genetic deterioration can be seen in elephant tusks, which are gradually becoming smaller. All elephants with exceptionally large tusks have already been poached.

Humans have always ...
