Wintering Conditions Region 7

[HalfAce]

Was taking a look at some recent news on the state site and came across this. The animals already had a couple of bad winters, and now another one that may be worse?... Hopefully it warms up, if it doesnt, i dont think there will be a positive outcome this spring.

Fish & Wildlife - Region 7

It's been a tough winter so far and the calendar suggests we still have several months ahead of us. Typically late winter and early spring months can continue to produce heavy snow fall.
Especially hard hit are resident wildlife populations, such as, antelope, mule deer, pheasants, turkey?s and Hungarian partridge.
The National Weather Service in Glasgow, MT. has reported Wibaux has accumulated 39.9 inches of snow, Glendive 26.2, Bloomfield 38.0 and Sidney 42 inches. Accumulation in southeastern Montana is above normal and snow is predicted to continue to move into the region.
During the previous several years? winter conditions have been comparably mild resulting in very limited mortality among resident wildlife populations. Populations responded with an increase in numbers that were consistently above the normal long term average. This population expansion provided FWP wildlife biologists an opportunity to increase and liberalize hunting permit and license opportunities. Conversely, FWP biologists must respond to reduced population levels through a reduction, or perhaps elimination of some permit and license?s. FWP biologists must respond to current conditions, winter mortality, herd health and trend survey results.
Impacts to upland game bird populations may be severe in some locations. Snow conditions restrict the bird?s ability to forage and prolonged cold begins to wear the bird?s resistance down. Cold increases the daily nutritional requirements and over time it uses up the fat reserves the birds need to weather such harsh conditions. In most locations birds are concentrated around hay stacks, tree rows and farm yards. These locations can provide a food source for wildlife in harsh winter conditions but prolonged exposure to deep cold and snow may result in winter mortality.
Resident wildlife populations experienced a tough winter last year and so far this year snow and cold temperatures have been worse. FWP personnel are already seeing incidents of winter mortality. Surveys by wildlife biologists found antelope numbers to be 30 ? 40% below the long term average in the fall of 2010. Mule deer surveys found the population to be 12% below the long term average. It can reasonably be expected that future surveys will find reduced population numbers. Wildlife populations can be predicted to suffer winter mortality due to these severe winter conditions. Fish, Wildlife and Parks will complete another sequence of surveys prior to setting 2011 hunting season quotas but it is reasonable to assume, if current conditions persist that harvest quotas for mule deer does and antelope may have to be reduced.
So far white-tail deer and elk populations seem to be weathering the harsh winter conditions. The public needs to know that our sustained winter conditions are having impacts on our local wildlife which may result in reduced hunter opportunity in the future.

In the Forsyth - Colstrip area we have had a bit more snow than we are used to. We have not had the 20 below temps yet though. Today is in the high 40's for the third day in a row and there are plenty of snow free areas for grazing (and the water is running). It's not odd to have 2 or 3 of these melt offs during the coarse of a winter. It looks like we should have another good grass year, so it isn't all gloom and doom.

Region 4 is looking very good,plenty of high snow pack and the lower elevations are now clear.Animals are looking fat and happy.

Region 6 is in the midst of a major winterkill and we have already recorded nearly 80 inches of snow here in Glasgow.

Winter takes toll on northeastern Montana wildlife

A doe antelope lies in a depression dug in a field near Glasgow last week. This winter's near-record snowfall is covering the animal's traditional winter food -- sagebrush. Antelope won't raid haystacks to eat.
.
GLASGOW ? The doe antelope had dug its own grave.

Weakened by months of cold, its usual foods covered in snow, it lay in a 3-foot-deep depression in the snow. Only its head was visible as it warily watched a car stopped along a nearby road. It was too weak to stand and flee.

?It's just a symptom of the severity of the winter,? said Kelvin Johnson, a wildlife biologist for Fish, Wildlife and Parks in Glasgow. He said the doe would be lucky to live one more day.

Train casualties

It has been a grim winter for wildlife. Earlier, Johnson had to help shoot 50 antelope that were injured after a train ran into a portion of a herd gathered on the railroad tracks near Hinsdale. Another 220 antelope were killed in the initial impact, their bodies scattered for more than a mile and left to feed scavengers.The antelope gather on the tracks because they are free of snow. Off the tracks, the snow can vary from 4 to 8 feet deep. To walk through it, the antelope move in single file, trading places breaking trail, much as flying geese trade leaders.

To feed, the antelope and deer have to paw through the snow. Johnson said the landscape would look like a crater-pocked moonscape to anyone flying over ? hundreds of holes scraped into the ground as the wildlife seek food.

?Can you imagine having to paw seven times for a nibble?? Johnson said.

Tough winter

Across northeastern Montana, continuous snow and cold have left antelope weakened and dying. Whitetail deer swarm haystacks like flies on meat. Carcasses of dead antelope and deer litter the hillsides and valleys. Only the golden and bald eagles, magpies and crows are getting fat as they scavenge the animal corpses.

?It's difficult out there, and they've been doing it since November,? Johnson said.

Bad winters are common across the rolling prairie of northeastern Montana, only miles from the Canadian border. But this winter has been harsher than normal, with snow coming earlier and heavier.

?We're well on the way to having a record-breaking winter,? said Mark Sullivan, FWP's Glasgow-region wildlife manager. ?It's tough on wildlife, no doubt.?

It will also be tough on hunters who are likely to see licenses reduced for antelope and mule deer.

?This has really been the land of plenty for mule deer,? Johnson said. ?Everyone's been coming out here. Probably people need to make another plan this year. We are going to lose a lot of deer.?

Fewer licenses

As Johnson explains it, much of the mule deer fawn crop was lost in the winter of 2003-04 that set a record for snowfall ? nearly 6 feet. Does that were weakened by the winter had few fawns.

?We're missing that age class that would be 6- or 7-year-olds now,? he said. ?I'm quite confident we'll see a limited age-class coming out of this.?

The winter also kills bucks that have low fat reserves after the fall breeding season.

?So bucks and fawns are the most susceptible going into winter with low or no fat reserves,? Johnson said. ?So we'll likely lose a lot of mature bucks.?

FWP warden Todd Anderson said he already has found dead mule deer so emaciated that no muscle remained along the backbone.

?I saw one buck that looked like it hurt to walk,? said warden Todd Tryan. ?He couldn't even hold his head up.?

The migration

Antelope migrate south to avoid such winters, moving through the plains in herds as large as 400 to 500. But man-made obstacles, like fences, can halt their progress. Sometimes in winter they can walk over the top of fences buried in the snow.

The Glasgow area's resident antelope push south to the Missouri River, some crossing Fort Peck Reservoir atop the ice.

In the spring, they'll attempt to return, but fences may be a greater obstacle to movement after snow has melted. And after ice has broken up, antelope sometimes try to swim across the reservoir.

The antelope around Glasgow now are those that have migrated south from Canada, taking over grazing lands that the resident herds have already abandoned. Moving 100 to 200 miles in deep snow is no easy task. Fawns are typically the first to die. Counts from a difficult winter in 2008 showed the antelope numbers dipping 20 percent, with most of the dead being fawns, Johnson said.

?It shows that migration works,? he said, keeping alive breeding adults while sacrificing the young.

In Sheridan County, a haven for pheasant hunters, Fish, Wildlife and Parks has begun allowing landowners to feed birds, according to Sullivan, the wildlife manager. The department allows feeding when 90 percent of the natural occurring foods are unavailable. Landowners are reimbursed for mileage and feed costs.

?Quite frankly, birds can spring back really fast if the habitat conditions are good,? Sullivan said. ?And we should see good habitat conditions this spring. They should have good nesting cover.?

With two more months of snow and cold ahead, the danger for wildlife is far from over.

?It's just one of those tough winters that we go through up here,? said Pat Gunderson, Glasgow's FWP supervisor. ?But when you're not in the game of animal husbandry it's a little hard to sit back and watch.?
