Introduction: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service 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. In 1971, ten wolves were flown into the island. The results of this program are shown in the following table.
Describe what happened to the deer and wolf populations between 1971 and 1980. How did the number of wolves affect the number of deer?
What do you think would have happened to the deer on the island had wolves NOT been introduced? How do you predict this would affect the ecosystem?
Look at the number of deer in “predation” and “starvation” columns. What conclusions can you draw about the introduction of the wolves on these values?
