What happens when a population reaches carrying capacity?
In 1970 there was about 2000 deers on an island. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus biologist feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, biologist decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd.
Do you think the deer on the island would be better off, worse off, or about the same without the wolves. Explain your position.
