The population of elephants in Kruger National Park, South Africa, grew exponentially for approximately 60 years after they were first protected from hunting. When population density of elephant is plotted against time, the shape of the growth curve would be

The J-shaped curve of exponential growth is characteristic of some populations that are introduced into a new environment or whose numbers have been drastically reduced by a catastrophic event and are rebounding. For example, the population of elephants in Kruger National Park, South Africa, grew exponentially for approximately 60 years after they were first protected from hunting.
