Welcome to Yellowstone National Park
Yellowstone National Park is said to be the first national park in the United States and the world! It was established when president Ulysses S. Grant signed the Yellowstone National Park Protection Act into law in 1872. The park is larger than the state of Delaware and situated in a region that has been volcanically and seismically active for tens of millions of years! Yellowstone National Park is an ecosystem containing many biotic and abiotic factors.
History of Protecting Populations
After becoming president in 1901,Teddy Roosevelt used his authority to protect wildlife and public lands by creating the United States Forest Service (USFS) and establishing 150 national forests, 51 federal bird reserves, 4 national game preserves, 5 national parks, and 18 national monuments by enabling the 1906 American Antiquities Act. During his presidency,Theodore Roosevelt protected approximately 230 million acres of public land.

In the late 1800s, grey wolf populations were hunted close to extinction. How would this affect the other species and abiotic factors?
Species critical to the overall health of an ecosystem
Keystone Species
How can ecologists predict the probability of the affects on the Yellowstone ecosystem if hot springs disappeared?
The chances of an event occurring
PROBABILITY
Photo Gallery
Explore different parts of Yellowstone Park using the VR tour or the photo gallery. What kinds of human impacts was Teddy Roosevelt trying to protect these ecosystems from?
Can natural changes be good?
Take a walk to Dragon's Mouth Spring. Observe the environment around the boardwalk. What natural causes could lead to this kind of destruction?
1. Use the graphs below to identify the keystone species. 2. How does the change in population of the keystone species affect the other 3 populations?
Why don't I see any of the animals I was expecting?
Hmm...this area does not look like the lively, green ecosystem I would expect. What happened to it?
Invasive Species
Food Web
Ecology
Probability
- examine evidence of the relationships between changes in the ecosystem and changes in populations
- explore the significance of keystone species in ecosystems
