Hunters and wildlife officials work together to control the population of feral swine. Feral swine are invasive predators of sea turtle eggs and competitors of black bears. When feral swine are successfully removed from the area by the hunters and wildlife officials, the sea turtle nesting success rate increases. In addition, removal of feral swine allows the black bear population to thrive.

Impact of Wolves in Yellowstone
Wolves are an important predator in Yellowstone National Park. When wolves were removed, the elk population grew too large. The elk ate too many trees and shrubs. The lack of shrubs and trees meant the bird population went down, as they needed the shrubs and trees for their habitat.
Later, when the wolves returned and were able to decrease the elk population, the numbers of trees (like the cottonwood tree) and shrubs were able to increase. When the trees and shrubs increased, the bird populations grew. The birds and the trees help each other. The birds help scatter seeds for new trees, while the trees provide shelter for the birds.
