Endangered Species
The most popular endangered species in Yellowstone National Park is the Grey Wolf.
Between 1914 and 1926, at least 136 wolves were killed in the park; by the 1940s, wolf packs were rarely reported. By the 1970s, scientists found no evidence of a wolf population in Yellowstone. Since then, we have been working hard to preserve and protect this precious species of wolves.
Currently there are estimated to be around 98 Grey Wolves in Yellowstone. We are working very hard, with many foundations and volunteers from all over the country working to protect the Grey Wolf.

Invasive Species
One of the invasive species in Yellowstone National Park is the bark beetle. Outbreaks of invasive bark beetles have savaged Yellowstone pine trees, as they have in many western forests, and other non-native species have brought disease into the park. This is killing many of the natural species in the park, which is not good.
