A reintroduced wolf in Yellowstone National Park
Elk herd browsing in meadows

In the 1930ies the last wolves were shot. In 1995 park rangers brought them back into Yellowstone NP. How would a predatorW-Logo.gif(English) like a wolf change and influence wildlife? Would they hunt down all elks and deer?

Task
  1. Why were many people against reintroducing wolves? What were they afraid of?
  2. How did the behavior or elks and deer change when wolves began living there again?
  3. What happened to the vegetation near rivers and lakes?
  4. How did that influence the number of birds?
  5. What kind of landscape and fauna do beavers need?
