 Amazing Facts

Reason 1: Without wolves and other large predators, ecosystems can go haywire. A 2001 study found that when wolves went extinct in Yellowstone, for example, the moose population ballooned to five times its normal size and demolished woody vegetation where birds nested. As a result, several bird species were eliminated in the park.

Reason 2: Scavengers thrive when wolves are around. The species that help themselves to wolves' leftovers include (PDF) ravens, magpies, wolverines, bald eagles, golden eagles, three weasel species, mink, lynx, cougar, grizzly bear, chickadees, masked shrew, great gray owl, and more than 445 species of beetle.

Reason 3: Wolf kills are also good for the soil. A 2009 study in Michigan's Isle Royale National Park found that wolf-killed elk carcasses dramatically enhanced levels of nitrogen and other nutrients.

Reason 4: Wolf kills feed more animals than hunting by humans, since wolves scatter their carrion over the landscape. Wolf kills benefit (PDF) three times more species than human hunting kills. The carcass above was a bull elk killed by a pack of eight wolves in Agate Creek, Yellowstone. The skeleton was picked clean by wolves and scavengers in less than five days.


Reason 5: When wolves disappeared from Yellowstone, coyotes preyed on pronghorn almost to the point of no return. But since wolves have returned, the pronghorn have come back. In fact, pronghorns tend to give birth near wolf dens, since coyotes steer clear of those areas.

Reason 6: Deer and elk congregate in smaller groups (PDF) when wolves are around. This helps reduce the transmission of illnesses like Chronic Wasting Disease.

Reason 7: Chronic Wasting Disease is a major threat to elk and deer in the West. Wolves can help by reducing sick animals' lifespans, in turn limiting the amount of time they can spread infections.

Reason 8: Yellowstone elk are less likely to overgraze near rivers and streams—damaging fragile ecosystems—when wolves are in the neighborhood.

Reason 9: Wolves help protect against climate change. A 2005 UC Berkeley study in Yellowstone concluded that milder winters, a product of climate change, have led to fewer elk deaths. This left scavengers like coyotes and ravens scrambling for food, but the problem was far less pervasive in areas where wolves were around to hunt elk.

Reason 10: Wolf tourism is an economic boon (PDF). Restoration of wolves in Yellowstone has cost about $30 million, but it's brought in $35.5 million annual net benefit to the area surrounding the park.

    Why can't I see the video??

  6. From the moment I was old enough to understand the difference between wolves and dogs I have felt protective of wolves. Sence a wolf showed himself to me, looked me directly in the eyes I have known his spirit recognized mine. There was no fear in my heart, only kindred knowing. Thank you for this furthering of my understanding.

    i love wolves and appreciate the enthusiasm with which this article was written, but i must point out that some of those reasons are pretty much the same, just worded differently or with different examples, like 2, 4 and 9 which talk about the benefit of other animals being able to feed on wolves leftovers, like 1 and 5 which both show how other species numbers can go haywire if wolves are removed (1 just shows how another species numbers jumped, while 5 shows how another species was almost killed off) like 6 and 7 which both talk about how wolves curb the spreading of disease and 1 and 3 both talk about the environment - it's like you really have 5 really good reasons with more different examples to back them up.

    Elk were introduced back into kentucky a few years back and are thriving , hopefully the state will bring in wolf to keep population down the way nature intended it to
