Tracking science: Biologist’s findings show forest diversity, health influenced by wolves

The consequences of an elk population without a top predator include a decline of the deciduous trees elk eat and a decline in many animals including songbirds. These consequences indicate that changes in the wolf population have trickle-down effects on other populations, a phenomenon known as a “trophic cascade”.

Scientists are making a strong case for trophic cascades proving that the presence, or absence, of wolves sends dramatic ripples throughout the food web.
