It's been only 15 years since gray wolves, after years of near-extinction, were reintroduced into Yellowstone National Park. The initial group of 66 নেকড়ে were transplanted into the park from Canada beginning in 1995. Now, আরো than 1,545 নেকড়ে roam Idaho, Montana, and Wyoming.Biologists say that a minimum of 2,000 to 3,000 নেকড়ে are needed within the area in order to keep them from disappearing again.The নেকড়ে have had tremendous জনপ্রিয় support from the beginning. Their reintroduction has been দ্বারা far the most publicized and celebrated of any wildlife reintroduction in the U.S. The নেকড়ে complete the Yellowstone ecosystem, which, without them, had too many hooved animals. The overabundance of some of the wolves' natural prey was altering the natural plant communities along stream banks, due to excessive trampling. With the নেকড়ে back on the scene, the Yellowstone natural community is much closer to what it was before most of the surrounding states were profoundly altered দ্বারা development and livestock ranching. The success of the growing নেকড়ে population has made a lot of money for the park, in sales of নেকড়ে paraphernalia, such as নেকড়ে T-shirts, sweatshirts, coffee cups, and বই from park gift shops. The নেকড়ে have also drawn thousands of tourists and wildlife supporters to the area,people who pay to sleep and eat in the park. Ranchers and hunters have been opposed to the নেকড়ে reintroduction from the beginning. Hunters say the নেকড়ে compete with them for native game, particularly elk. Ranchers say the নেকড়ে kill their calves. নেকড়ে do occasionally kill calves and sheep. The ranchers and hunters apparently are concerned only with their own livelihoods and recreation, respectively. They don't appear to care about wolves, which were here long before we were. নেকড়ে in the U.S. were decimated দ্বারা an unprecedented extermination campaign in the early 1900s, funded দ্বারা the U.S. which distributed posters encouraging people to shoot নেকড়ে on sight, and even offered a bounty for dead wolves. It worked. There were virtually no নেকড়ে left in the lower 48, although before Europeans settled North America, নেকড়ে were common throughout every region of the continental United States. If US Fish&Wildlife's plan to take নেকড়ে off the endangered species তালিকা goes through, hunters and trappers would be allowed to obtain permits to kill wolves. As long as at least 450 নেকড়ে survived, the animal would remain fair game. If their numbers dropped below 300, they'd be put back on the endangered species list.
