Many scientists say gray wolves still need protection. Yes, wolf numbers have increased. But scientists say the population is still too small. After all, wolves don’t live in most of their former range (see map below).
Plus, wolves are a keystone species. That means they have a big effect on their ecosystems. Wolves prey on large mammals, like elk. Fewer gray wolves would mean more elk. The elk eat shrubs, trees, and other plant life. That would be bad for animals that depend on those plants to survive. This includes birds, beavers, and more.
“Without wolves, forests are less healthy,” says wolf expert Adrian Treves.
Many people fear that removing wolves from the endangered species list would lead to an increase in hunting. Gray wolves were delisted in 2020. Not long after, hunters in Wisconsin killed more than 200 of them in less than three days.
