There main source of food either dies out as well of decreased in size.
Wolves were common in the entire American West at the time Yellowstone National Park was founded. Government agencies actually paid hunters to kill wolves (and other "bad" animals) until wolves became almost extinct in the Lower 48.
The re-introduction of wild wolves into the Yellowstone Eco-system has been a total success in that humans PARTIALLY undid the destruction they unleashed on creation. The boost to winter tourism in the region, in order to see wolves in the wild, has been a HUGE economic benefit to the region -- FAR exceeding any losses due to predation by wolves.
Originally the wolves in the Yellowstone region were killed to near extinction on government order. The last ones were skilled off in the early 1900s. It hasn't been until recently (1995) that re-introduction acts were placed despite ranchers/farmers objections. The new wolves were brought in from Canada. Hope that answers your question.
when there were no wolves in yellowstone park yellowstone park had to much elks so when the wolves arrived again the wolves killed all the elks
It is important that the wolves be reintroduced to Yellowstone National Park because predators help to maintain the health of the ecosystem in general. Without wolves, there are too many grazing animals, such as deer, and not enough food for them to eat.
All of them... That's what "extinct" means. Although there are no known populations of gray wolves in South Dakota, that does not mean that gray wolves are extinct. There are gray wolves in other states, such as Minnesota which has the largest population of wolves. A successful reintroduction program has been done in Yellowstone National Park in Wyoming.
Wyoming Idaho, Montana, and Wyoming Established in 1872, Yellowstone National Park is America's first national park. Located in Wyoming, Montana, and Idaho, it is home to a large variety of wildlife including grizzly bears, wolves, bison, and elk.
the whole yellowstone evacuates the national park because the supervolcano is very very dangerous and can kill thousands of people at atime with all the magma
By the wolves not being there, the elck got very over populated, and they ate all the prairie dogs. The prairie dogs all died out and the plants that they ate, started to grow everywere.
Yes, it is in the Northeast Corner of the park. It is not a long drive to get out of the park through Cooke City but all that is considered Lamar Valley is within Yellowstone National Park.
No. Most of Yellowstone lies outside of the Yellowstone Caldera, though this caldera still takes up a large portion of the park. A larger portion of the park is in the older Island Park Caldera, which partly overlaps the Yellowstone Caldera. This still takes up a minority of the park.
Yellowstone park had no wolves for a long time and the large elk population kept all young alder and aspin trees grazed to extinction. There were no young (alder & aspin) trees in the park. Wolves were introduced in the 70's and now there are large groves of young trees - this is due to a dramatic decrease in the elk population - due to predations by wolves.
You asked a very interesting question. If the area doesn't have enough wildlife to feed the wolves (they generally go after the older animals such as deer, elk, moose) or will even kill rodents, then the wolves will move the pack to another area. I just saw an interesting program on wolves regarding Yellowstone National Park. A very astute conservationist hired by the park realized that the river was changing at a dramatic pace and also aspen trees and other vegetation were disappearing at an alarming rate. After much studying they realized at one time they blamed the wolves for the low count of deer, elk and moose. What did they do .. they either killed or trapped and relocated wolves out of the park. Without the wolves there to hunt down the game the different species of deer, etc., grew at a rapid rate and it was the very animals they were protecting that unbalanced nature! The deer, elk and moose were basically eating all the aspen and also the willow beds by the rivers, so they had to introduce wolves back into the National Park. There is one problem with this ... there are a few ranchers on the outskirts of Yellowstone and they are complaining that the wolves are eating their stock. So far nothing has changed and the wolves are still free to roam Yellowstone. Sometimes humans just can't leave mother nature alone long enough to do her job!
