WILDLIFE WATCHING — Don't just tell your friends and family next time you see a moose in Washington. Tell somebody who really cares.
Washington Department of Fish and Wildlife researchers want to hear about your moose observations when you’re afield this fall and winter, especially in northeast Washington.
A new smartphone application makes moose reporting easier than the old-fashioned method of logging onto a the agency's website.
WDFW wildlife biologist Jared Oyster, who coordinates moose survey work in eastern Washington, says this citizen science survey is designed to collect long-term data on the population status and trends of moose in Washington.
WDFW has been monitoring moose annually using helicopter surveys, and is developing a population estimate for the northeastern part of the state. But monitoring is expensive and limited by weather conditions and other logistical challenges. A broad geographic coverage of moose observations, collected in a standardized and repeated way by the public, can be very helpful tracking long-term changes.
WDFW adapted the smartphone app system originating in Canada, (originally initiated in 2012 by Dr. Mark Boyce, and coordinated at the Department of Biological Sciences University of Alberta).

Hunters can use their Wild ID numbers as identification on the app while non-hunters can enter any 11-digit number to identify themselves.
The system also asks for observations to be reported within Game Management Units.
WILDLIFE RESEARCH — U.S. and Canadian researchers have found they can get a good idea of a grizzly bear’s diet over several months by looking at a single hair. The technique, which measures residues of trace metals, can be a major tool in determining if the threatened animals are getting enough of the right foods to eat, according to a release from Washington State University.
The technique can also help determine how much mercury bears are ingesting.
“You can use the technology for both applications,” said Marie Noël, lead author of a mercury study on polar bears and a more recent study, published in Science of the Total Environment, on how the technique works. “You can see how much mercury they’re getting but also estimate how much salmon they’re eating.”
Charles Robbins, a Washington State University wildlife biologist and director of the WSU Bear Research, Education and Conservation Center, said the technique helps determine how bears are recovering and if they have enough habitat to meet their food needs.
Grizzly bears are listed as threatened under the Endangered Species Act in the continental United States and endangered in parts of Canada.
“You can see bears chasing down salmon, but other than saying, ‘bears eat salmon,’ that really doesn’t give you much information,” Robbins said in the release. “So we’d like to know where the energy and protein is coming from to create either large bears or small bears or cubs and help them with their reproduction. We’d like something that integrates all that information over a 24-hour period, a week, a month, a year.”
Hair grows throughout a bear’s active season, and because it is almost entirely protein, “it’s a good indicator of the protein sources to the bears,” he said.
The new technique has a laser run down the length of a single hair. As it vaporizes one location, said Noël, the gases are analyzed by a mass spectrometer.
The researchers analyzed the hairs of 20 wild bears from British Columbia and five captive grizzlies at the WSU bear center. The captive bears were fed a diet of commercial bear chow and apples while grazing 12 hours a day on white clover.
For about a month, they were fed Yellowstone Lake cutthroat trout, which have high levels of mercury from nearby thermal features. Almost to the day, the researchers saw mercury levels rise in the captive bears, as well as levels of copper and zinc. The scientists then correlated those levels with levels seen in the wild bears to see what they had been eating.
“Taken together,” the researchers write, “the pattern obtained from these three elements can provide information on salmon consumption… as well as the amount of salmon consumed… by wild grizzly bears.”
WILDLIFE WATCHING — Paul Wik, state Fish and Wildlife Department district biologist in southeastern Washington, checked a golden eagle nest south of Asotin recently to determine the age of the chicks.
Researchers plan to capture one chick pre-fledging to install a solar powered transmitter.
Here's a story about the state's efforts to monitor the big eagles.
BIG GAME — Moose studies launched in the last year or two are beginning to turn out some data, although it's preliminary and conclusions can't be drawn, yet.
Here's an update on a study in British Columbia that will be raising the startling question:
Why are moose starving?
Biologists share what they've learned so far in B.C. moose study
A five-year study of moose in the interior of British Columbia launched in 2013 hopes to figure out why the number of moose is on the decline. Last weekend at the B.C. Wildlife Federation’s convention, Gerry Kuzyk, an ungulate specialist with the Ministry of Forests, Lands and Natural Resource Operations, said that, of the 19 radio-collared moose that have died so far during the study period, nine were killed by wolves, three by unregulated hunting, three due to starvation, one by a vehicle collision and three due to unknown causes.
WILDLIFE — Helicopters soon will be flying over the Coeur d'Alene and St. Joe river drainages to help wildlife biologists get started on a major multi-year elk research project.
Idaho Fish and Game Department researchers will be working with a private helicopter contractor starting around Jan. 19 to capture about 100 cow and calf elk, take blood samples and fit them with GPS tracking collars.
The collars will allow researchers to monitor the elk habitat use and seasonal movements. A morality signal from the transmitters tell researchers when the elk dies, so survival rates can be calculated and causes of death can be investigated.
- A similar project in Western Montana has helped biologists determine, among other things, that mountain lions are taking a far higher toll on elk than wolves.
In this study, cow and calf elk are being captured with either nets or tranquilizer darts depending upon the terrain and density of the forest canopy, said Phil Cooper, department spokesman in Coeur d'Alene.
"Prior to the development of GPS collars, biologists had to use an antenna in hand or on a plane to determine an animal’s location," Cooper said. "Most locations were usually midday, during weather that allowed safe flights and good visibility. Now, locations are taken regardless of weather, giving a much better picture of habitat uses and requirements."
WILDLIFE RESEARCH — Washington Department of Fish and Wildlife biologists recently battled difficult weather to capture 28 moose and put radio collars on 24 moose in northeastern Washington. That brings the total to more than 50 collared moose involved in the state's first major study of the species.
A gunner in a helicopter targeted the moose with tranquilizer darts while ground crews rushed in to take blood samples, measurements and other information before attaching the collars that hold GPS transmitters.
The project began last year with the capture of 28 adult cow moose for a five-year study of their habits, movements and survival rates.
Researchers monitor the moose year-round.

WILDLIFE — I don't have numbers, but I have enough information from hunters, wildlife watchers and wildlife researchers to confidently say that theft of trail cameras has reached epidemic levels.
I've seen posts from a few anonymous thieves rationalizing their behavior by saying they don't want people snooping into land they love or they don't want other hunters figuring out what they already know.
But the greedy creeps are still thieves, any way you look at it.
Here's news of another assault on ethics, research and public safety.
Nine wildlife cameras used to track elk near North Bend have been stolen.
The Transportation Department was using the cameras in a project to prevent elk collisions on Interstate 90.
Workers noticed nine of the project's 18 Reconyx cameras missing on November 10th. The cameras had protective steel boxes, media cards, and shielded padlocks. Some were camouflaged into their surroundings to deter people from stealing them.
Crews removed nine other remaining cameras as a precaution.
One of the cameras took a picture (above) of a possible suspect, a man with a bandanna over his face.
"These cameras were doing important work that were able to help us build something that could really stop these collisions from happening," said Harmony Weinberg, DOT public information officer. "It was really crucial work."
BIG GAME — Wolves likely have played a bigger role in the serious decline of northeast Minnesota’s moose population than originally believed, and there’s no evidence yet that climate change has been a major factor, according to a new analysis by renowned Minnesota wolf researcher Dave Mech.
The story was reported last week by Doug Smith of the (Minneapolis) Star Tribune.
Mech doesn’t dismiss climate change as a possible factor in the declining moose herd, but said evidence presented in earlier research done by the Department of Natural Resources "just doesn’t hold up."
Instead, an increasing wolf population in at least part of the northeast moose range might have contributed to the decline, Mech and John Fieberg, an assistant professor at the University of Minnesota, concluded in a recently published paper. The state’s northeast moose herd has fallen 50 percent since 2006, to an estimated 4,350 animals last winter.
In the earlier studies, DNR researchers considered the statewide wolf population stable between 2000 and 2010, which was correct, Mech said. But they didn’t consider that the wolf population in an area that Mech has been studying - which overlaps part of a moose study area - had increased to the highest levels in 40 years.
"My data tends to indicate the problem was there were more wolves," Mech said in an interview. "But that doesn’t necessarily mean that’s the only answer. Is there some change affecting moose that allows wolves to take more of them, or is it merely that there’s more wolves?"
If wolves are a major factor in the moose decline, Mech said the DNR could allow hunters to kill more wolves in the moose range until the population recovers.
Michelle Carstensen, DNR wildlife health program supervisor, who in 2013 began conducting an adult moose mortality study using radio-collared animals, said the previous DNR studies looked at overall mortality, but researchers weren’t able to determine cause of death in most cases.
"We assumed wolves were accounting for a portion of that mortality, but we didn’t know how much," she said.
But now officials are finding how much impact wolves are having on moose mortality. The study radio collars alert researchers when an animal has died, and provide GPS coordinates so they can be quickly located and a cause of death determined.
So far in the study, the overall mortality rate is 26 percent, which is a concern. Normal stable moose populations have an 8 to 12 percent mortality rate. Wolves have accounted for 55 percent of the mortality (17 of 31 deaths); the rest died from health issues.
"The level of wolf predation on the adults is well in line with what we’d expect," Carstensen said. "It’s the overall mortality 61/87from all causes63/87 that has us concerned."
She noted that the northwest moose herd plummeted from about 4,000 in the ’80s to fewer than 100 today, and wolves had nothing to do with that. Those moose died from health-related issues, possibly driven by climate changes.
And, she said, adult moose in the northeast keep dying in summer, fall and early winter "when they shouldn’t be dying."
Carstensen said the results from current ongoing moose studies, which also include moose calves, habitat and diet, should eventually provide researchers with answers to the mystery. "There still might not be a smoking gun; it might be very complex," she said.
So far, in a different study involving collared moose calves, 67 percent of the mortality was due to wolves.
"Wolf predation is probably a little higher than we expected," DNR researcher Glenn DelGiudice said. "But we knew it would be a main source," he said, and it’s far too early to draw any conclusions.
He is planning on collaring more moose calves next spring, and said several years of data are needed.
Mech’s latest report says the northeast moose population was relatively unaffected by wolves from 1997 to about 2003 and that wolf numbers tended to parallel moose numbers. However, after the wolf population in his study area jumped 81 percent between 2000 and 2006 - from 44 animals to 81 - moose numbers began declining.
"We don’t know how far and wide that increase 61/87in the wolf population63/87 took place, but it did in our study area, and that area was adjacent to the moose study area," Mech said. He said it’s reasonable to surmise the wolf population in the rest of the moose study area also was rising, rather than remaining stable, as it was elsewhere.
Moose are a prime food source for wolves in the northeast, so as the moose population declines, one would expect the wolf population to eventually fall, too. "That seems to be happening in our study area," Mech said. The wolf population there increased until 2012, but he said it appears to have since declined.
The DNR estimated the state’s wolf population last winter at 2,423, stable from 2013.
So if the wolf population in moose country is declining, will moose rebound?
"That depends on what’s going on," Mech said. "If it’s strictly wolves, the moose population will recover. But if there are other factors involved - parasites, disease or warming temperatures, then it’s hard to say."
And if wolves turn out to be a major factor, then the DNR will have to decide whether to try to lower the population of one iconic animal to try to boost the population of another.
WILDLIFE RESEARCH — Washington State University researchers are learning whether grizzly bears make and use tools.
With claws and teeth that can rip open anything from a beer can to beaver dens and moose carcasses, it seems as though tools would be unnecessary.
But while it’s too soon to reach a broad scientific conclusion, researchers say at least one female bear at the WSU lab is demonstrating that use of tools comes naturally.
The study, being conducted at WSU’s Bear Research Education and Conservation Center, is documenting eight grizzlies faced with the challenge of getting their claws into a dangling food snack that’s too high to reach, reports Linda Weiford of WSU News. No training is involved. The researchers are chronicling innate learning behavior.
Information gleaned from the study can be used to help wildlife managers solve grizzly-related challenges and problems, according to researchers, and also assist zookeepers in keeping captive bears mentally and physically stimulated. The study should be completed this fall.
“While it’s generally accepted that grizzly bears are intelligent creatures, until now no scientific research had been conducted on their problem-solving skills,” said WSU veterinary biologist Lynne Nelson, who is overseeing the study.
Here are more details from the WSU report:
In WSU’s controlled setting, eight brown bears—three males and five females—are being tested separately and are at various phases of the experiment, said Nelson. To date, a 9-year-old grizzly named Kio has sailed through each phase, essentially nailing the hypothesis that the species is capable of tool use.
Here’s how the study works: Inside the grizzly bears’ play area, a donut is hung on a string from a wire, too high for the animals to reach. First, each bear is tested to see if it will stand on a sawed-off tree stump to reach up and get the donut down. Once this is mastered, researchers move the stump away from the hanging donut and place it on its side.
Here’s where things get challenging. The bear must move the stump until it is positioned underneath the donut and then flip the stump over into a makeshift footstool.
Kio mastered this early: “She manipulates an inanimate object in several steps to help her achieve a goal, which in this case is to obtain food,” said Nelson. “This fits the definition of tool use.”
The other grizzlies are in the process of figuring out the feat, she explained, which confirms what the center’s scientists have long suspected about the keen brain power of bears. Frequently, Nelson and her colleagues witness grizzlies doing remarkable things, including using a single claw in a key-like manner to try to open locks.
Why should humans scientifically assess tool use among America’s greatest predators?
- “If grizzly bears are capable of using tools to interact with their environment, that’s important for us to know because it provides a fuller picture of how they think,” said WSU veterinary student Alex Waroff, who designed the study and who, with Nelson, tests the bears five mornings a week.
- “By better understanding their cognitive abilities, we can help reduce encounters that can turn deadly for bears and humans alike,” he said.
- Such understanding also could shed light on whether the species is capable of manipulating its environment when faced with changes in the wild, such as shifts in habitat conditions or declining food sources, he explained.
Most of the center’s grizzly bears were deemed “problem bears” in the wild and were brought to WSU as an alternative to being shot and killed.
“Grizzlies are smart foragers and they’ll work hard to get at food – which, as we’re seeing, can include some pretty sophisticated strategies,” Nelson said.
Incidentally, the glazed donuts, donated by a local grocery store, are used to entice the bears for the study and aren’t part of their normal diet, said Nelson.
“Yes, they like sweets – just like humans,” she said. “But we’re careful to restrict their intake.”
WILDLIFE — On Sunday, Aug. 10, the Idaho Department of Fish & Game, with the permission of the United States Fish & Wildlife Service, euthanized an adult male grizzly bear that had been responsible for a series of livestock killings in the Island Park, Idaho. The grizzly bear was trapped by Wildlife Services, a division of the United States Department of Agriculture.
Wildlife Services is contacted whenever a predator is thought to be responsible for the death of domestic livestock.
The depredations had occurred on the portion of Harriman State Park that is located west of Island Park Reservoir. Because of the age and history of the bear involved, the decision was made to remove the bear.
Idaho Fish and Game officials say that once bears have learned to key in on a specific food source it is highly likely they will continue the behavior, even if moved to other locations.
WILDLIFE WATCHING — Monday, June 9, is the deadline to comment on the Idaho Wolverine Conservation Plan proposed by the state Fish and Game Department's. The document was released May 19 for a 21-day public review.
Wolverines are members of the weasel family. In the northern United States, they occupy high-elevation alpine and subalpine habitats with spring snow cover and cool summer temperatures.
The plan lays out the state's course in protecting wolverine populations and their habitats to ensure their long-term viability in Idaho. The plan includes statewide wolverine status and distribution, factors affecting population and habitat, priority areas for conservation, and supporting actions to benefit wolverines in Idaho.
WILDLIFE WATCHING — Remote cameras, GPS monitoring and DNA testing continues to reveal more about one of the most secretive of North American carnivores.
Montana, Alberta researchers report result of wolverine study
A $1.7-million study begun in 2009 by Parks Canada, the Miistakis Institute in Calgary and the Western Transportation Institute at Montana State University to survey the wolverine populations in mountain parks has been completed, with 64 different wolverines identified.
WILDLIFE RESEARCH — The region's wildlife researchers are flying high — and low — with this week's weather.
The big dump of snow followed by clear weather is perfect for using helicopters to locate and capture critters so transmitter collars can be attached for research. Fleeing animals bog down in the snow giving the pilot and gunner the best conditions for capture.
Methods used include shooting tranquilizer darts directly from the helicopter to the animal in a low-flying chase or shooting a net from the helicopter before landing and administering the drug after subduing the animal.
Washington Fish and Wildlife staffers took advantage of the weather Monday to recapture a female wolf near Ione to replace a faulty collar that had been attached after the wolf was trapped in July. On Tuesday they caught another female wolf in the same area and attached a collar. The staffers are working to put collars on other wolves in these prime conditions.
Idaho is scrambling to get more collars on elk in the Coeur d'Alene River drainage this week for a large-scale study.
USFWS again extends comment period on protection of wolverines
A dispute on the reliability of conflicting research on wolverines was cited by the U.S. Fish and Wildlife Service for its decision to extend by six months the public comment period on a proposal to put the elusive species under federal protection.
ENDANGERED SPECIES — An organization of wildlife officials for Western states is asking the federal government to delay a possible listing for wolverines as a threatened species, which could mean an end to trapping outside Alaska for the animal’s fur.
According to the Salt Lake Tribune, the Western Association of Fish and Wildlife objects to any listing based solely on fears climate change could shrink the wolverine’s wintry terrain along the spine of the Rocky Mountains and other Western ranges.
“Climate change models are not a reason to list species under the Endangered Species Act,” Bill Bates, a representative from the Utah Division of Wildlife Resources, told The Tribune.
Bates said the population of wolverines has actually increased since the time of European settlement, even though it’s estimated fewer than 300 of the elusive, snow-loving carnivores roam the mountain ranges of the Lower 48 states.
“We can wait and see what happens with climate change in the next 20 to 30 years,” Bates said.
Federal officials say they aren’t trying to use the wolverine as a means to regulate greenhouse gases, but they say it’s a fact climate change threatens the wolverine as much as it does the polar bear. The Interior Department listed polar bears as threatened five years ago because of loss of their primary habitat, sea ice, due to climate warming.
In January, the U.S. Fish & Wildlife Service proposed protections for the wolverine throughout the continental U.S. It opened a public comment period that’s set to end on Monday.

WILDLIFE WATCHING — A male harlequin duck, known to be at least 17 years old, was recently identified in Glacier National Park by University of Montana researchers and Glacier National Park scientists.
- The banded duck is believed to be the third oldest on record. The oldest known banded harlequin duck has a recorded age of 18 years and 10 months.
“Prior to these findings, harlequin ducks were reported to live up to only 10 years of age, which makes this finding a positive indicator of the health and longevity of harlequin breeding populations in Glacier National Park,” said Lisa Bate, Glacier Park biological science technician. “Research indicates harlequin ducks mate for life unless something happens to one member of the pair. This old male has returned the last three years with the same female.”
Researchers launched the study in 2011, using radio-telemetry and banding to learn more about the location of harlequin nests and factors affecting offspring survival.
Upper McDonald Creek is considered an important breeding stream for harlequin ducks, comprising 25 percent of known broods produced in Montana. The area also has the highest density of breeding harlequins in the lower 48 states.
About 40 pairs of harlequins in the park are known to be in Glacier Park.
- Idaho's St. Joe River also is host to summering harlequin ducks, especially up the Marble Creek tributary.
Read on for more detals about the harlequins.

Idaho issues 2 kill permits on wolves near Carey after 31 sheep killed
Between May 10 and May 12, John Peavey, the owner of the Flat Top Ranch near Carey, Idaho, lost 13 ewes and 18 lambs to wolves. Idaho Wildlife Services has issued a kill permit for up to two wolves.
—Idaho Mountain Express (Sun Valley)
WILDLIFE — Elk numbers in Montana's Bitterroot Valley are up this year mostly because of better calf survival, according to reseachers.
This year’s aerial spring count found 7,373 elk in the five hunting districts that encircle the Bitterroot Valley. That's the fourth highest number of elk spotted by biologists in the 48-year history of the annual spring survey.
Range conditions and more emphasis on controlling wolves, cougars and bears played a roll in the increase, biologists say.
ENDANGERED SPECIES — Some pro-wolf groups say hanging red ribbons on fences around pastures will protect cattle from wolf attacks.
The theory is getting another test this spring in the Wenatchee area, site of the most recently documented new wolf pack in Washington.
Question: Does this mean the end of the open range?
Let's just say there could possibly mean a BIG MARKET for red ribbon in the West.

A new study led by U.S. Geological Survey biologist Steve Knick has confirmed that sage grouse need undisturbed habitat and solitude for successful reproduction.
Researchers found 99 percent of the active 3,000 leks studied in 355,000 square miles of historic sage grouse range in the West found were in areas where no more than 3 percent of the land had been disturbed by human activity. —Idaho Statesman
PREDATORS — A wolf witnessed hunting a deer in a Wenatchee residential area Tuesday is a dose of reality a little too close to home for some people.
It's a reminder that urban deer need to be controlled, and that we need to have measures in place so we can control wolves.
We need to be aware of wolves — all of us. The landscape has changed.
Andy Walgamott of Northwest Sportsman magazine offers this reminder of the well reported developments in the past few years:
It’s a reminder that it’s not just ranchers who will need to adapt to living with the species, but mountain bikers, hikers, mushroom pickers and others who frequent the woods. They will also need to adjust their behavior and become more alert in the outdoors and better understand wolves’ proclivities to avoid the rare negative interactions.
WILDLIFE — Northern Rockies gray wolf packs are highly structured socially. Only the alpha male and alpha female breed.
Generally, according to Washington Fish and Wildlife biologists:
- Mating occurs in January.
- Pups are born in dens in April and the pack supports the nursing mother with food.
- The female and pups begin uniting with the pack at a rendezvous site in May.
- Pups are weaned in June.
- By October, the pups are actively hunting with the pack.
- By December, the pups appear full size and some older wolves may have been dispersed from the pack to take care of themselves and find new mates and territories.
- Wolf packs are known to kill other wolves as they expand or defend territories averaging 350 square miles. Dispersing wolves are especially vulnerable.
A pack is defined as a minimum of two wolves hanging out together.
A breeding pack must have a minimum of one male and one female wolf hanging out together during the winter breeding period.
PREDATORS — Idaho's gray wolf population at the end of 2012 was at least 683, a decrease of 11 percent from 2011, according to the federally required annual state wolf monitoring report (http://fishandgame.idaho.gov/public/wildlife/wolves/) posted online today by the Idaho Fish and Game Department.
Humans killed 418 of the 425 wolves known to have died in the state last year by hunting, trapping and state and federal agency control efforts to protect livestock, the report says.
However, the number of documented packs had increased and wolves were occupying territories throughout the state.
Montana also has reported a decrease in wolves in its 2012 annual report, the first decrease since 2004.
In Washington, where wolves are still under Endangered Species protections, the number of wolves increased signficantly from 2011 to 2012, with the number pegged at around 100.
Idaho biologists documented 117 packs in the state at the end of 2012 — an increase of seven from 2011 — plus 23 border packs that overlap in Montana, Wyoming and Washington. But total numbers of wolves have gradually decreased because of hunting and other efforts since the population peaked at a minimum of 856 in 2009.
Of the 66 Idaho packs known to have reproduced, 35 packs qualified as breeding pairs at the end of the year, the report says. Those reproductive packs produced a minimum of 187 pups.
A new crop of pups will be born in dens across the state this month.
Wolves were confirmed to have killed 73 cattle, 312 sheep and two dogs in Idaho last year, the report says.
The Panhandle Zone was occupied by 15 documented resident packs in 2012 — up three from 2011 — plus five known resident border packs, three suspected packs and one other documented group during 2012, the report says. Three new resident packs were documented in 2012.
Wolf recovery and monitoring reports from Idaho, Montana, Wyoming and more recently from Washington and Oregon are posted on the U.S. Fish and Wildlife Service's Northern Rockies Gray Wolf website.
PREDATORS — With wolves stacking up in northeastern Washington at an alarming rate, perhaps Washington ought to take a cue from Montana, which has announced plans to review the guidelines set in the state's wolf management plan.
Montana is rounding up the state's disbanded 12-member Wolf Management Advisory Council in Helena, April 12, for a meeting to review and discuss the wolf management plan they helped to create.
"A lot has transpired since the council last met in 2007," said Jeff Hagener, Montana Fish, Wildlife and Parks Department director. "Governor Steve Bullock and I have invited the members to gather in Helena for a one-day meeting to review the status of the wolf in Montana today and to discuss the effectiveness of the management plan."
WILDLIFE — Research underway in Washington, Oregon and Idaho seeks to understand more about a wilderness icon, North America's reclusive carnivore — the wolverine.
Last weekend we took a glimpse at how citizen scientists are helping Idaho Fish and Game monitor a range of carnivores including wolverines in the Idaho Panhandle.
KING 5 TV this week has an excellent update (above) on wolverine research in the North Cascades, including footage of a a fiesty critter trapped, collared and released.
WILDLIFE — This male golden eagle has worn a GPS “backpack” for eight years to provide information about home range size and habitat use in Eastern Washington, according to the Washington Department of Fish and Wildlife Facebook page.
Now at least 13 years old, he was recently recaptured by the agency's raptor researcher who removed the equipment to let him spend the rest of his life flying “free.”
ENDANGERED SPECIES — Two of several gray wolf-related bills being considered in the 2013 Washington Legislature have passed out of committee and could be considred by the Senate.
Andy Walgamott of Northwest Sportsman has this update on the status of the bills.
ENDANGERED SPECIES — Although Idaho won't be releasing its 2012 year-end gray wolf surveys report until March, the Washington Fish and Wildlife Department released its federally required report last week, as we reported.
The details are posted on the agency's gray wolf webpage, but Andy Walgamott of Northwest Sportsman Magazine has compiled this easy-to-read rundown of all the known wolf packs in Washington with updated info.
ENDANGERED SPECIES — Although the unofficial estimates have been out for weeks, the Washington Fish and Wildlife today confirmed that the number of confirmed gray wolves and wolf packs in the state nearly doubled during the past year.
Based on field reports and aerial monitoring for the annual report, the 2012 survey confirms the presence of at least 51 wolves in nine wolf packs with a total of five successful breeding pairs. The previous year’s survey documented 27 wolves, five wolf packs and three breeding pairs.
A wolf pack is defined as two or more wolves traveling together. A successful breeding pair is defined as an adult male and female with at least two pups that survive until the end of the calendar year.
“The survey shows that our state’s wolf population is growing quickly,” said Nate Pamplin, WDFW wildlife program director. “That growth appears to be the result of both natural reproduction and the continuing in-migration of wolves from Canada and neighboring states.”
Pamplin said the actual number of wolves in Washington state is likely much higher than the number confirmed by the survey, noting that field biologists currently suspect the existence of two additional packs.
In addition, lone wolves often go uncounted and those that range into Washington but den in other states are not included in WDFW’s survey, he said.
Considering those factors, and applying an estimate of the average pack size in other western states, there could easily be as many as 100 wolves in Washington, Pamplin said.
“The survey is the baseline we use to monitor wolves’ progress toward recovery,” he said. “While we’ve stepped up our monitoring efforts significantly over the past year, we recognize that it does not account for every wolf within our state’s borders.”
One of the nine packs represented in the survey is the Wedge pack, which now has two confirmed members in northeastern Washington. Last summer, WDFW eliminated seven members of the pack to end a series of attacks on an area rancher’s cattle that left six calves dead and 10 other animals injured.
Pamplin said wildlife biologists do not know whether the two wolves living near the U.S.-Canada border in Stevens County are members of the original Wedge pack or whether they are new arrivals from inside or outside the state.
“Either way, we were confident that wolves would repopulate that area,” he said. “We really hope to prevent the kind of situation we faced with the Wedge pack last summer by working with ranchers to use non-lethal methods to protect their livestock.”
The gray wolf is currently listed by the state as an endangered species throughout Washington and is federally listed as endangered in the western two-thirds of the state. Once common, wolves were essentially eliminated in most western states during the past century because they preyed on livestock.
Under the state’s Wolf Conservation and Management Plan, wolves can be removed from the state’s endangered species list once 15 successful breeding pairs are documented for three consecutive years among three designated wolf-recovery regions. Four pairs are required in Eastern Washington, four pairs in the North Cascades, four pairs in South Cascades/Northwest Coast and three pairs in any recovery region.
Reports of possible wolf sightings can be made to WDFW’s wildlife reporting line, (877) 933-9847.
