Yellowstone National Park (wolf reintroduction)

Yellowstone National Park’s wolf reintroduction, beginning in 1995, was a conservation effort to restore the park’s natural ecosystem. Wolves had been absent for decades, causing imbalances among species like elk and deer, which overgrazed vegetation and affected other wildlife. Reintroducing wolves helped control prey populations, leading to more balanced predator-prey dynamics. This, in turn, allowed plant life to regenerate and supported a healthier, more diverse ecosystem. The project demonstrated how restoring predator species can positively influence ecological health, highlighting the importance of keystone species in maintaining natural balance.
