The Spokesman-Review released the following article:

“Montana has just announced that at least 566 wolves inhabit the state, according to the 2010 annual wolf conservation and management report released today by Montana Fish, Wildlife & Parks. The report  shows Montana’s minimum wolf population increased about 8 percent in 2010, compared to a 4 percent increase last year and an 18 percent increase in 2008. The minimun numbers indicate that wolves have increased to 108 verified packs and 35 breeding pairs.

The U.S. Fish and Wildlife Service followed Montana by posting the complete 2010 Northern Rockies wolf update, which includes the census from Idaho and Wyoming.

The report by Idaho Fish and Game biologists documented a minimum of 705 wolves in 87 packs at the end of 2010. In addition, they documented 22 border packs along boundaries with Montana, Wyoming and Washington. Of the 54 Idaho packs known to have reproduced, 46 qualified as breeding pairs by the end of the year. These reproductive packs produced a minimum of 189 pups in 2010.

For 2009, Idaho reported a minimum population of 843 wolves in 94 packs in the state along wtih 20 documented border packs

Idaho’s decline is at least partly due to the difficulty of monitoring wolves in remote areas of central Idaho, federal officials said.

“I’m certain we could have successfully reduced the wolf population in 2010 if we could have proceeded with our planned, science-based hunting season,” said FWP Director Joe Maurier. “When you look at our management success in 2009, we had a vigorous wolf population at the end of the year and we were still able to control its growth. It’s clear that a management strategy that includes hunting can play an important role in managing wolves in Montana. It is a tool we need and one we’re still trying to get back.”

Last year, FWP joined in a federal lawsuit in defense of the U.S. Fish and Wildlife Service’s 2009 decision to delist wolves in Montana and Idaho, but not in Wyoming. The U.S. District Judge in Missoula, however, reinstated federal protections of wolves in the northern Rocky Mountains on Aug. 5.

The minimum recovery goal for wolves in the northern Rocky Mountains was set at a minimum of 30 breeding pairs—successfully reproducing wolf packs—and a minimum of 300 individual wolves for at least three consecutive years and well distributed throughout the recovery area. The goal was achieved in 2002, and the wolf population has increased every year since.

FWP’s report is part of the annual federal recovery update required by USFWS. The end of 2010 count also estimates that at least 343 wolves inhabited Wyoming, up slightly from 2009. The count in Idaho dropped slightly to 705, likely due to the state’s decision to reel in monitoring efforts in central Idaho’s rugged wilderness areas. Annual reports from Idaho, Wyoming, and information about wolves in Yellowstone National Park and the northern Rockies are available from the USFWS online at http://westerngraywolf.fws.gov.

The northern Rockies’ “metapopulation” is comprised of wolf populations in Montana, Idaho, and Wyoming. Four packs are now verified in Oregon and Washington within the northern Rocky Mountain Distinct Population segment. Today, at least 1,651 wolves in 244 packs, with about 111 breeding pairs, live in the region, where wolves can travel about freely to join existing packs or form new packs. This, combined with wolf populations in Canada and Alaska, assures the genetic diversity of wolves throughout the region.

Each of the three geographic regions of Montana inhabited by wolves showed slight increases in 2010 from 2009:

• northwestern Montana’s population exhibited the greatest increase where the population grew to a minimum of 326 wolves, in 68 verified packs, and 21 breeding pairs. Seven of the packs reside on reservations where they are managed by Tribal authorities.
• western Montana’s population increased slightly to at least 122 wolves in 21 packs, and eight breeding pairs.
• southwestern Montana’s population increased slightly to at least 118 wolves in 19 packs, and six breeding pairs.

About 24 packs occur along Montana’s border with Idaho, 18 of which are included in the Montana estimate. This demonstrates the continued influence of the robust wolf population in Idaho on Montana’s wolf population. Additionally, six packs are shared with Wyoming, four of which are included in Montana’s population. 

Compared to Idaho and Wyoming, at 24 percent Montana had the highest rate of known human-caused mortality of wolves in 2010. Officials say that’s due to Montana’s wolf population, as a whole, living on a combination of public and private lands.

Maurier noted, however, that Montana’s wolf population still increased and remains well above recovery goals. “Nearly all of Montana’s wolves live outside national parks,” he said. “That means an intensive management strategy is needed to strike the right balance between wolves and public acceptance. Unfortunately that’s out of our hands, but it’s crystal clear that this species is fully recovered. Montana has made room for wolves and it is our position that Montana must be given the authority to manage them.”

Many of us think of communication only as talking or writing to each other. Those are two ways humans share information every day. How do wolves “converse?” Even though they cannot talk or write, wolves communicate effectively in several ways.

Wolves use body language to convey the rules of the pack. A wolf pack is very organized. Rule number one says that the pack is made up of leaders and followers. The pack leaders are the male parent and the female parent – usually the father and mother of the other pack members. They are likely to be the oldest, largest, strongest and most intelligent wolves in the pack. They are known as the alpha wolves and are usually the only members of the pack to produce pups.

Any wolf can become an alpha. However, to do so, it must find an unoccupied territory and a member of the opposite sex with which to mate. Or, more rarely, it moves into a pack with a missing alpha and takes its place, or perhaps kills another alpha and usurps its mate.

The alpha male and female are dominant, or in charge of the pack. To communicate dominance, the alphas carry their tails high and stand tall. Less dominant wolves exhibit submissive behavior by holding their tails down and often lower their bodies while pawing at the higher ranking wolves.

There are two levels of submissive behavior: active and passive. Active submission is a contact activity in which signs of inferiority are evident such as crouching, muzzle licking and tail tucking. The behaviors typical of active submission are first used by pups to elicit regurgitation in adults. These behaviors are retained into adulthood by subordinate wolves, where they function as a gesture of intimacy and the acceptance of the differentiation of the roles of the wolves that are involved.

Passive submission is shown when a subordinate wolf lays on its side or back, thus exposing the vulnerable ventral side of its chest and abdomen to the more dominant wolf. The subordinate wolf may also abduct its rear leg to allow for anogenital inspection by the dominant wolf. If two wolves have a disagreement, they may show their teeth and growl at each other. Both wolves try to look as fierce as they can. Usually the less dominant wolf, the subordinate one, gives up before a fight begins. To show that it accepts the other wolf’s authority, it rolls over on its back. Reactions to this behavior may range from tolerance (the dominant wolf standing over the submissive wolf) to mortal attack, particularly in the case of a trespassing alien wolf. Following the dominance rules usually keeps the wolves in a pack from fighting among themselves and hurting each other.

Wolves convey much with their bodies. If they are angry, they may stick their ears straight up and bare their teeth. A wolf who is suspicious pulls its ears back and squints. Fear is often shown by flattening the ears against the head. A wolf who wants to play dances and bows playfully.

Wolves have a very good sense of smell about 100 times greater than humans. They use this sense for communication in a variety of ways. Wolves mark their territories with urine and scats, a behavior called scent-marking. When wolves from outside of the pack smell these scents, they know that an area is already occupied. It is likely that pack members can recognize the identity of a packmate by its urine, which is useful when entering a new territory or when packmembers become separated. Dominant animals may scent mark through urination every two minutes. When they do so they raise a leg, this dominant posture utilizes multiple forms of communication and is called a “Raised Leg Urination” or RLU.

Wolves will also use urine to scent mark food caches that have been exhausted. By marking an empty cache, the animal will not waste time digging for food that isn’t there.

Wolves use their sense of smell to communicate through chemical messages. These chemical messages between members of the same species are known as “pherimones.” Sources of pherimones in wolves include glands on the toes, tail, eyes, anus, genitalia and skin. For example, a male is able to identify a female in estrus by compounds (pherimones) present in her urine and copulation will only be attempted during this time.

Of course, their sense of smell also tells them when food or enemies are near.

Have you ever heard a wolf howl? They’re not howling at the moon they are communicating. They call any time of the day, but they are most easily heard in the evening when the wind dies down and wolves are most active. Wolves’ vocalizations can be separated into four categories: barking, whimpering, growling, and howling. Sounds created by the wolf may actually be a combination of sounds such as a bark-howl or growl-bark.

Barking is used as a warning. A mother may bark to her pups because she senses danger, or a bark or bark-howl may be used to show aggression in defense of the pack or territory.

Whimpering may be used by a mother to indicate her willingness to nurse her young. It is also used to indicate “I give up” if they are in a submissive position and another wolf is dominating them.

Growling is used as a warning. A wolf may growl at intruding wolves or predators, or to indicate dominance.

Howling is the one form of communication used by wolves that is intended for long distance. A defensive howl is used to keep the pack together and strangers away, to stand their ground and protect young pups who cannot yet travel from danger, and protect kill sites. A social howl is used to locate one another, rally together and possibly just for fun.

Can you think of ways that humans communicate without using words?

How Do Wolves Say Hello?

Have you seen dogs jump up to greet their owners, bark at strangers or roll over when another dog approaches? Then you already know something about how wolves communicate. Dogs inherited most of their language from their ancestors, the wolves.

Wolves use three different languages:

1. Sound – Howls, Barks, Whimpers and Growls.
2. Special Scents – Scats, Urine and Pherimones.
3. Body Language – Body Positions and Movements and Facial Expressions.
