In 1995, a population of 31 gray wolves was introduced into Yellowstone National Park. The population of the gray wolves fluctuated in the 20-year period after introduction. In 2019 an estimated 80-110 wolves are present in the park. Wolves, elk, and bison are native to Yellowstone, but the wolves disappeared in the 1920s due to excessive hunting. Wolves are primarily carnivores, and elk and bison are primarily herbivores. A team of scientists monitored the population of wolves in Yellowstone for the first 20 years after their release. Number of Individuals 200 180 160 140 120 100 80 60 40 20 0 Number of Individuals Figure 1.
