How wolves change the physical geography of an area by causing a trophic cascade 

This amazing short YouTube on the re-introduction of wolves to the Yellowstone National Park is a fascinating example of the importance of the Interconnection concept in the Australian Curriculum: Geography. 

"The concept of interconnection emphasises that no object of geographical study can be viewed in isolation."

In particular the Australian Curriculum: Geography involves holistic thinking that involves studying the interconnections between phenomena and processes within and between places. The clip outlines how the re-introduction of wolves into the park has not only made massive positive changes to habitats and animal life but also changed the nature of the rivers in the park though a process called trophic cascading. A great positive biogeography story based on interconnection and interdependency. 

Thanks to Jonathon Noble, DECD Education Manager at the Adelaide Zoo for forwarding this example of interconnection.
