Reasons Why We Need Wolves
How Wolves fight climate change, and 10 other reasons to protect Wolves
Every few months, my friend Brendan disappears into the wilderness to track wolves. The wolves are tagged with radio collars as part of the Yellowstone Wolf Project, which has been observing the animals in their natural environments in an effort to help protect them since 1995. Brendan's work as a volunteer is to follow the wolf packs (from a safe distance) and record their behavioral, social, and predation habits. Sometimes he'll go a day without spotting a wolf, just sitting in sub-freezing snow fields and staring through a scope. Other times, he and his partners will stumble across the juicy meat of the job—a wolf howling atop a boulder, a pack devouring a weakened elk—and the biting, windy wait will all be worth it.
Wolves entered the national limelight this week when Rep. Mike Simpson (R-Idaho) and Sen. Jon Tester (D-Mont.) slipped a measure into the budget deal to strip gray wolves of their Endangered Species Act protections in most of the Northern Rockies—the first time a species has been removed from the list for political reasons, rather than scientific ones. The lawmakers argue that the bill alleviates stress on big-game herds and helps out ranchers and farmers, whose livestock fall victim to the predators. The bill would lift protections for wolves in five Western states and allow wolf hunting to resume in Montana and Idaho. Environmentalists worry that removing wolves from the ESA list could open the doors to allow other endangered species to be delisted as well.
Whether wolves have a negative impact on the Northern Rockies remains a contentious issue. Here's how Brendan sees it: "Gray wolves and elk have been coexisting for 10,000 years. The problems really stem from people, who are contributing to habitat degradation and forest fire suppression." Studies show that wolves play vital roles in maintaining healthy ecosystems, and could even help stave off some of the effects of climate change. Scroll through the slideshow to find out how.
Reason #1: Without wolves and other large predators, ecosystems can go haywire. A 2001 study (PDF) 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. Photo of elk in the Blue Range Wolf Recovery Area courtesy the US Fish and Wildlife Service
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.

Wolf Hunt Open House In CdA
No quota has been set for the wolf during this year’s season. The
Idaho Department of Fish and Game has proposed a wolf hunting season for
Aug. 30 to March 31. Jim Hayden, IDFG regional wildlife manager, said the
commission has also proposed a trapping season for the wolf, Dec. 1
through Jan. 15. “We’ve added a month to the front of the hunting season
and this will be our first trapping season,” Mr. Hayden said. The
public is invited to an open house at the Panhandle Region office at
2885 W. Kathleen Avenue in Coeur d’Alene.
Regional staff will be on hand to answer questions and to solicit input
on the 2011 wolf season proposals. Mr. Hayden said the
changes should bring an 18 percent harvest increase. Overall, the IDFG
expects to see a 20 percent reduction in the state’s wolf population

India male tiger plays doting dad to orphaned cubs
Forest officials in northern India say a male tiger appears to be caring for two orphaned cubs in an extremely rare display of paternal feeling.

Wildlife officials say a male tiger protecting cubs is very unusual
|
The cubs lost their mother in February in the Ranthambore tiger reserve. Officials there say they believe the male tiger, named T25, is their father.
Wildlife experts say cubs are usually raised by their mothers and male tigers often kill cubs they come across.
Officials believe there is no recorded evidence of males behaving like this.
Photographs taken by hidden cameras in the forest reserve in India's northern Rajasthan state have documented the tiger's behaviour. The most recent images show the male tiger walking just a metre behind one of the cubs,
Ranthambore field director Rajesh Gupta told the BBC.
The cubs, who are believed to be about eight months old now, were first seen on 29 January with their mother T5, a forest official in Ranthambore told the BBC.
He said after the tigress died on 9 February, the cubs were being reared in the wild by forest department staff.
The cubs are too young to make a kill on their own and are being provided with bait by forest staff.
"During my visit to the park on Monday 30 May, I was standing on the top of a cliff and I saw one of the cubs down below eating the kill," Mr Gupta says.
"It is seen in good health," he said. It appears as if the male tiger is allowing the cubs to eat their kill and not taking it for himself."
Cubs as food
"It's very unusual," UM Sahai, Rajasthan's Chief Wildlife Warden, told the BBC from the state capital, Jaipur.
"Normally the tigress keeps an eye on the cubs while the father is a visitor, who is seen off and on, especially when he comes to mate with the tigress," he said.
Wildlife experts say that it is common for male tigers to never even set eyes upon the cubs they father - especially when the mother is not present and many male tigers will simply see cubs as food.
Ranthambore, one of India's best known tiger parks, has about 40 tigers, including about a dozen cubs.
According to the latest tiger census figures released in March, India has 1,706 of the big cats.
The country had 100,000 tigers at the turn of the last century but there has been a serious decline in numbers since then.
Experts say that 97% of tigers have been lost to poaching and shrinking habitats.

Wolves as hunters
(There is no documented account of a healthy wolf ever attacking a human.)
Wolves are very shy around people and try to avoid them in the wild
Wolves kill only to eat - to survive. Because wolves usually hunt for large animals, (although wolves are opportunistic and will eat smaller prey) they work together to catch their prey. Wolves will eat a healthy, strong animal if they can catch it.(Wolves need an average of three to ten pounds
of meat each day).
Hunting is not always successful, so their bodies are designed to feast (eat a lot)or famine (eat nothing).
Wolves can eat as much as 22
pounds of meat at a time and then may not eat again for many days.
Wolves require from one to three quarts of water per day, depending on
the size of the animal, the climate, and the moisture content of the
prey. When hunting in winter the wolf will conserve energy when ever
possible, by following the same trail as the prey animal, staying
upwind, and staying out of sight of the prey as long as possible. When
it is time to strike the wolf will start wagging their tails with
excitement. Some times when young pups are with the hunt they may dash
after the prey in the excitement and spoil the hunt.
Wolf Hunting Tactics
Wolves are primarily nocturnal animals that avoid the heat of day. They generally commence hunting at dusk.
Wolves detect prey by three primary means, sent (most common), tracking, and chance encounters.
After prey is detected, wolves may split up to search through brush,
travel on ridge tops searching for the prey below, or test herds looking
for signs of weakness.
It has long been recognized that wolves often take advantage of wear
members of the herd. In 1804, Captain Clark of the famed Lewis and Clark
expedition wrote that prairie wolves followed buffalo and fed "on those
that are killed by accident or those that are too pore or fat to keep
up with the ganges."
Later researchers reinforced the image of the wolf as a predator of
the very young, the very old, the weak, of the diseased. Aldolph Murie, in the Wolves of Mount McKinley,wrote:
"Many bands seem to be chased, given a trial, and if no advantage is
gained or weak animals discovered, the wolves travel on to chase other
bands until an advantage can be seized."
Lois Crisler notes in Arctic wild, "In all our time in the
arctic, the only healthy caribou we saw or found killed were fawns with
big herds." She observed that adult caribou killed had "hoof disease, or
lung tapeworm, or nostril-cloging ... botflies." In a 1980 study in
northeast Alberta, T. Fuller and L.B. Kieth found that "wolves killed
disproportionately more young, old and probably debilitated moose (Ales
alces), as well as more female calves."
In fact, the only animal that habitually preys upon prime mature animals is man.
Although it does not prey only on the weak and the ill, the wolf is
opportunistic, and it is inevitably the disadvantaged that are the
easiest to catch.
The Selection
Weakened animals may show thier condition to predators through body
stance, uncoordinated movements, the smell of wounds or infection, or
some other tangible signal. The reading and evaluation of these signals
comprises what Barry Lopez has poetically termed "the conversation of
death."
Once a weak individual is selected by a pack, wolves will usually
travel upwind. By traveling upwind, the sent of any prey will be carried
to them. They will follow the air currents directly to the game. Or,
they may follow the sent trail left by a game animal's foot tracks and
body odors.
The Chase
Just before the chase wolves
prefer to make there final approach downwind so there body sent is not
carried to the prey species, alerting it to their presence.
Prey that runs is usually chased. Prey that stands its ground may be
able to bluff off its pursuers. Moose and Elk often take to deep water
or swift rivers and await departure of the pursuing wolves, But more
often than not the wolves wait. While the majority of the pack rests,
one or two members test the prey for signs of fatigue.
Usually the chases are short, but L. David Mech has stated that "One wolf I know of chased a deer for 13 miles."
David Gray described one such encounter in Canada's high Arctic in the musk-oxen of Polar Bear Pass:"the wolves approached to within a hundred meters of the herd ... one wolf lay down as two others circled the milling herd."
Contrary to popular belief, most prey chased by wolves actually gets
away. In one study, only three percent of the moose that were tested
ended up being killed. The percentage of prey that is killed is called
the "predation efficiency," and in spite the wolf's prowess as a hunter,
the majority of his prey escapes.

ended up being killed. The percentage of prey that is killed is called
the "predation efficiency," and in spite the wolf's prowess as a hunter,
the majority of his prey escapes.
When the attack comes, the prey is usually seized by either the nose or the rump. Rarely, if ever, does a wolf hamstring a prey animal. This is one of the oldest and most pervasive false beliefs held about wolves. As late as 1980, the Aubon Society Field Guide to North American Mammals stated that the wolf kills "by slashing tendons in the hind legs.", this is pure myth. The actual death of the prey is usually caused by massive blood loss, shock, or both. Sometimes with smaller prey a neck bite will snap a backbone.
The Alpha wolf will eat first, Wolves usually begin to feed on the
rump, if it was exposed during the chase, or else on the internal
organs. The muscle and flesh is the last portion of the prey that is
eaten, in contras with human habits. Having strong jaws allows the wolf
to crush bones to get to the soft marrow, it also helps the wolf eat
most of its prey leaving very little waste at the killing site.
Another myth is that packs are required to bring down large prey;
several observers have seen single wolves catch and kill elk and moose.
The first wolf to return to Sweden after the extermination of its wolf
population regularly brought down large moose by itself.
There is evidence that wolves have some knowledge of proper prey
management.
L. David Mech found one pack in Minnesota that varied its killing by
hunting in a different part of its territory each year, allowing prey
numbers elsewhere to recover, aiding the long-term survival of the pack.
Wolves hunt out the weak, the sick, the old, and the injured.
They help the population of prey animals like the elk, deer, moose, and
caribou, by taking away the weak and letting the strong survive. This is
important part in
the ecological system. By enhancing the strength into the herds.
Without animals like the wolf to eliminate the weak, old , sick
and injured, the herd of deer would swelter. They would become so
numerous that they would starve to death. The wolf helps keep
them healthy by insuring the breeding of the strong.
Wolves also help feed other animals. When a wolf kills and
eats, he sometimes can't eat it all. This leftover feeds animals such as
the buzzard, the possum,fox, coyotes and eagles. They help keep the
forest clean by removing the sick before it can spread.
Brown Bear Hunting in Russia

Without a doubt, a Russian brown bear hunt is the best in the world.
The population of brown bears in Russia has been stable for years.
According to estimates, its population may approach 140,000, which is
more than any other country. The Russian brown bear habitat runs
uninterrupted from the Finnish border to the Pacific Ocean for 10000 km.
(6000 mi.). The Pacific coast and the European parts of the country
have the largest density of bear population.
We offer bear hunts in three distinct areas: European North-West, Central and Southern Siberia, and the Pacific coast.
Eurasian Brown Bear in St. Petersburg, Novgorod,
Vologda and Karelia regions. Spring season over baits is offered only in
Karelia from April 20-25 until May 20. Majority of Eurasian Brown bear
hunts are conducted from high stands over bait. Early fall hunts are
done from stands along oat and barley fields. Later, bears are hunted by
stalking or baiting. The season usually starts on August 15 and ends
around October 30. The largest European bear ever taken by one of our
clients was 360 kg. (790 lbs.), with a hide 260 cm. long (almost 9 ft.).
The Siberian Brown Bear is a large representative of
the species. Both Spring and Fall hunts are offered. Spring hunts
usually involve stalking and glassing over the hillsides. In the Fall,
bears are hunted by stalking and baiting, and occasionally with dogs.
Far Eastern Brown bear of Kamchatka peninsula and
the Pacific Coast of the Russian Far East produce the largest bears in
Russia, or perhaps in the world. These salmon-eating bears rival in
size, and in density of population the bears of Alaska and the Kodiak
Island. However, the prices of these Russian hunts are usually lower
than those in Alaska. Kamchatka has become the number one destination
for bear hunters in Russia, although many hunters do not realize that
the less-often hunted areas of the Russian Northern Pacific Coast offer
as good, or perhaps an even better chance of getting a very large bear.
Wolf Hunting in Russia
The habitat of the wolf covers huge territories from the western
borders of Russia to the shores of the Pacific Ocean, and from the
Arctic Tundra to the steppes of Kazakhstan and Mongolia. This is the
most wide spread large game animal in Russia. The population of wolf has
been stable for years, and in some areas has increased, causing damage
to game and livestock. In some areas of Russia and several former Soviet
Union republics wolves attacks on humans are common enough not to make
news.
Wolves found in Russia can be much more aggressive towards humans than
those in North America. There have been verifiable reports of wolves
attacking humans in Russia. The largest animals, found in the North
Eastern tundra, may reach 2 meters (just under 7 ft.) from the tip of
the nose to the tip of the tail and weigh up to 100 kg. (220 lb.). Visit
a Zoology museum in Moscow to see one of those specimens.
Hunting this intelligent, wary and highly adaptable animal is very
difficult. Many trophies are taken by chance encounter. Organized wolf
hunts frequently rely on baiting and calling. In the areas, where wolves
numbers become unmanageable, helicopters or snowmobiles can be used.
However, the most exciting wolf hunting is done in the European part of
Russia in an old tradition, which is not well-known in other countries.
When the pack is located, it is encircled with a 3-5 km. (2-3 mi.) long
tether, having small swatches of fabric (the “flags”) stitched to it
every few feet. The fabric is usually of red color to be easier spotted
over the background of snow by the guides Since it retains a human scent
for several days, wolves tend to stay within the encircled area. When
the hunters arrive, the pack of wolves is already “flagged”.
Therefore,
the hunt must begin immediately. Preparation takes a great deal of
footwork, but the success rate is very high. Four to five hunting days
are usually sufficient.
The wolf season is opened year around, but the best time is
January-February. January wolf hunts can be combined with driven wild
boar hunts.
