Trophic Cascades: How a Single Change Can Reshape an Entire Ecosystem
Nature is a highly complex system, much like the human body, where even the smallest changes can have far-reaching, unpredictable consequences. One of the most powerful examples of this interconnectedness is a phenomenon known as trophic cascade—a ripple effect that spreads throughout an entire ecosystem when a top predator is introduced or removed.
One of the most famous and well-documented examples of a trophic cascade is the reintroduction of gray wolves to Yellowstone National Park in 1995. This single action transformed the park’s landscape, altered animal populations, and even changed the course of rivers.
Let’s explore how trophic cascades work, why they are critical for ecological balance, and what Yellowstone teaches us about nature’s complexity.
