A ‘trophic cascade’ occurred in Yellowstone National Park in the US after wolves were introduced after being absent for nearly 70 years.
George Monbiot explains the term and how wolves change rivers.
For those of you who stumble on the word ‘deer’ for what are elk, a note: This is because the narrator is British and the British word for “elk” is “red deer” or “deer” for short. The scientific report this is based on refers to elk so this is for the sake of accuracy.
