How Wolves Change Rivers


Watch the video and create a diagram/visual way of showing the chain reaction of events.

Can you think of any examples or imagine any example of what would happen in a New Zealand context. For example-Elephants introduced into inner city Nelson, Lions in Nelson Lakes National Park?

Can you find any more information about what a trophic cascade is? Any other famous examples?
