Tree Growth

Environment

  • This increase in trees directly affects the population of animals in the environment
  • They have more to feed on
  • Since the wolves have returned, they have kept the elk population under control, and more trees are able to grow

Tree Growth

  • Growth of trees in Yellowstone decreased after wolves were eradicated there,because too many elk fed on tree seedlings

Compensation

  • Wolf reintroduction policies include compensation for livestock losses

  • Wolves help keep the coyote population down, who are more likely to kill livestock

Economy
