Where this comes from
NPSpecies is the National Park Service’s database of the species documented in each park. We show its vertebrate lists as published: a species is “present” when the park has confirmed it, “unconfirmed” when reports exist without verification, and “not in park” when the NPS has ruled it out (often tagged “historical” for animals that once lived there). Lists lag reality by months or years and seeing an animal is never guaranteed. Plants, insects and other invertebrates are not included here. Browse the full NPSpecies list for Yellowstone.
