Wolves released in 1995 reshaped Yellowstone’s ecosystem.

In 1995, the reintroduction of fourteen wolves into Yellowstone National Park marked a pivotal moment in ecological history. Initially, scientists had hoped to restore balance to the park’s ecosystem, unaware of the profound ripple effect this decision would set in motion.

The wolves, absent from the park for nearly 70 years due to human intervention, were reintroduced to naturally manage the burgeoning elk population. Little did anyone anticipate the cascade of changes that would follow.

The wolves, acting as apex predators, altered the behavior of the elk. With the resurgence of the wolf population, the elk adjusted their grazing patterns, avoiding areas where they were vulnerable to predation. As a result, vegetation in those areas regenerated and flourished, promoting the growth of willows and aspens that had been previously overgrazed.
