Tough Winter For Elk, Deer, Even New Pronghorns In Southeast Washington

Editor’s note: Updated April 11, 2019 with comments from WDFW biologist Michael Atamian

The six-by-seven bull rose with the rest of the herd of 150-plus elk that bitterly cold March morning outside Walla Walla and began trudging south through the snow.

But then as Scott Rasley, a longtime WDFW staffer and wildlife conflict specialist for the Blue Mountains, watched the animals make their way towards the Oregon state line, “like they do every morning,” he witnessed something extraordinary.

The big bull turned to its left, then “laid down, put his head back, and died in 30 seconds.”

Didn’t take any final breaths, didn’t let out any death moans. Just. Died. On the spot.

“I have never seen anything like that in 38 years,” Rasley said.

He said the bull otherwise looked like it was in OK shape and was suffering no apparent external injuries.

“The bull had the normal amount of lack of fat that we would find this time of year. And after a late and very cold snowy winter, basically none,” Rasley said.

It was a hard thing for him to see, given how he much he’s enjoyed working with elk — “a magnificent animal” — for WDFW in some of the state’s best wapiti country over the past 35 years.

“I always hate to see a magnificent bull like this die for no reason,” Rasley said.

But it’s also symbolic of the harsh conditions Eastern Washington deer, elk and antelope suffered through in February as below-zero temperatures and record or near-record snows hit the region and lingered well into March, burying forage and pushing the animals below their normal winter range habitats.

The bull’s death and those of other critters are briefly described in recent biweekly WDFW Wildlife Program reports from February and last month.

“Veterinarian Mansfield and Wildlife Health Technician Cole have been receiving an increase in reports of dead mule deer in eastern Washington,” reads one section of the March 1-15 report. “To date, necropsies and laboratory testing indicate that the deer are in a state of chronic negative energy balance, likely a result of prolonged winter weather and deep snow pack.”

It states that one deer had a “severe” ulcer, probably because it had been suddenly forced to forage on things its stomach couldn’t deal with.

“When eaten, they ferment in the stomach, producing large amounts of acid, which cause ulcers and enter the bloodstream, usually resulting in death,” the report states in reminding us that it’s not as easy as just putting out piles of corn or whatnot for starving critters.

That report and others from February show photos of carcasses of deer found on the Grande Ronde and recently translocated pronghorns near Tri-Cities, as well as a cow elk in the snow on the 4-O Wildlife Area that was still alive but too weak to stand with the end near.

“We lost a lot of deer along the Snake River, as well,” Rasley added. “Most were last year’s fawns. I can’t remember the last time we had 40 mile an hour north winds with below zero temps and heavy snow at the same time. Pretty sad.”

Most impacts occurred east of the Cascades, but hungry trumpeter swans in the Sequim area “decimated” an organic farm’s broccoli and cauliflower crops when everything else was under a heavy blanket of snow, according to one report.

With winter-weary deer and elk expected to struggle through more bad weather, in early March WDFW closed several wildlife area units on the eastern side of the Blue Mountains to public access to reduce disturbance on wintering game. On the south side of the range, ODFW urged shed antler hunters to postpone their searches.

But the Wildlife Program reports also share images or stories of wildlife powering through late winter — a herd of 23 bulls hunkered behind a tree line to get out of a cold wind on a 3-degree day; the snow burrows of sage grouse in the northern Columbia Basin; large numbers of elk gathered at Yakima and Kittitas Counties’ feedlots; turkeys in hay barns; a cougar taking shelter under a barn.

It’s the nature of nature, the strong — and the lucky and the accidents of birth — survive the cold season to reproduce, strengthening the herds and flocks.

I  emailed a number of wildlife biologists across the Eastside’s southern tier to find out how this winter compared to the last harsh one that hit this country, 2016-17, which began a lot earlier.

Paul Wik, the district bio for the Blues, feels that 2018-19 was “likely less severe” of a winter than two years ago because the worst weather occurred during a seven- to eight-week window.

But he also thinks the animals may have gone into it with less fuel in the tank, per se.

“I think that the animals were likely in poorer condition than normal going into this winter due to the lack of fall green-up that normally occurs,” Wik said. “With the fall rains occurring too late in the year for grass to germinate in the fall, the deer and elk were not able to access higher nutritional forage in the fall, predisposing them to the severe late-winter conditions.”

As for the impact hunters might see, he says some parts of his district could see reduced deer harvest, the impact may be larger in 2021 when last year’s fawns would be legal bucks.

“Our deer surveys in December documented normal fawn recruitment, but that was prior to the winter weather which may have impacted them,” Wik said.

In the district to the north of him, Michael Atamian said it was “hard” on deer and elk.

“In general I would say it was not as hard as the 2016-17 winter in Spokane and Lincoln Counties. However, in southwest Whitman County this year was likely a bit harder than 2016-17 on mule deer,” he reported.

“We might see a bit of an impact in harvest success a couple years down the line in the Whitman County area,” Atamian noted, adding, “However, the ability of a hunter to secure private land access will have greater impact on their success overall.”

News From Idaho: Most Fawns, Calves Surviving Winter; Springer Season Opens 4-27

THE FOLLOWING ARE PRESS RELEASES FROM THE IDAHO DEPARTMENT OF FISH AND GAME

Most radio-collared fawns and elk calves survived unusually snowy February

78 percent of fawns and 94 percent of calves were still alive through February, but they’re not safe yet

Despite February storms that battered much of Idaho and pushed snowpack and precipitation above average in most areas, radio-collared young fawns and elk calves were faring relatively well across the state through the end of February.

Idaho Fish and Game biologists have been monitoring 207 mule deer fawns and 201 elk calves captured earlier in the winter and fitted with telemetry collars.

Through the end of February, 78 percent of the collared fawns and 94 percent of the calves were still alive. That compares with 88 percent of the fawns and 97 percent of the calves surviving through February in 2017-18, and 55 and 80 percent in 2016-17.

While snowpacks and precipitation totals are above average for most of the state, the late arrival of winter weather in 2019 has made for an easier winter for big game than in 2016-17, according to Daryl Meints, State Deer and Elk manager for Fish and Game.

In 2016-17, a prolonged, severe winter resulted in some of the lowest survival rates recorded for mule deer fawns and elk calves. Prior to what was a record-setting February for snowfall for many areas in the state, 2018-19 winter had been a mild-to-average snowfall and temperatures for most of Idaho.

While the weather may be trending warmer so far in March this year, the young animals aren’t “out of the woods” yet. In fact, the March and April are often when fawn and calf mortality is the highest because the young animals’ fat reserves are rapidly depleting and their body’s need time to convert digesting fresh forage.

“April is crucial,” Meints said. “That’s the make-or-break month, when their gas tank is hitting empty. What is going to matter now is how soon winter ends, or how soon spring shows up.”

If the warm weather continues through the end of April, Meints expects fawn survival will fall somewhere in the average range, while calf survival will be above average.

“But if for some reason we get a weather system that is cloudy, cold, and wet, and we don’t get that spring green up on south-facing slopes, we could be in for some additional mortality,” Meints said.

People getting outdoors to recreate in the spring also need to be conscious and considerate of wildlife, particularly big game that remains on low-elevation winter ranges. Despite warmer temperatures and spring green up, deer, elk and pronghorn antelope still need to be left undisturbed to give young animals a better chance of surviving their critical first winter.

F&G Commission sets spring Chinook to open April 27

Limited fishing days on Clearwater, Salmon, and Little Salmon rivers, and the Upper Snake closed

The Idaho Fish and Game Commission approved spring Chinook fishing on the Clearwater, Salmon and Little Salmon rivers during their meeting on Wednesday, March 13 in Boise.

Fishing will open on April 27, with a two-day-a-week season on the Clearwater River and a four-day-a-week season on the Salmon and Little Salmon rivers. The season will run until sport anglers’ shares of the harvest are met (which varies by river) or Aug. 11 — whichever comes sooner.

Due to very low projected returns the Upper Snake River in Hells Canyon, fisheries managers did not propose to open a spring Chinook season for the fishery this year.

Chinook have just started entering the Columbia River and a small portion of them are working their way through Columbia/Snake river systems. Here’s current salmon counts at the dams.

Fisheries managers are forecasting a run of about 32,000 spring Chinook through Lower Granite Dam, which is about 25 miles downstream from Lewiston and the last of the eight dams that returning salmon cross on their way back to Idaho. The forecast is similar to last year’s actual return of 39,000, and below the 10-year average return of 75,000.

Included in the forecast are about 26,000 hatchery Chinook and 6,000 wild Chinook. The 2018 returns were 32,000 and 7,000, respectively, and the 10-year averages are 58,000 and 17,000. Forecasts are a starting point for managing Chinook returns, and they will be adjusted as fish migrate through the river systems.

Because the forecasted Chinook return for the Salmon River basin is about 8,700 fish, and the sport anglers’ share would be 1,430 fish this year. Fishing will be open Thursday through Sunday, with a limit of four total fish, only two of which may be adults.

For the Clearwater River basin, the projected return is about 9,400 adult fish, and the sport anglers’ harvest share would be 470. Fishing will be open on Saturday and Sunday, with a limit of four total fish, only one of which may be an adult.

Just 123 adult fish are projected to return the Upper Snake River in Hells Canyon, where fisheries managers do not expect a sport angler harvest share at all.

“Due to extremely high flows at Hells Canyon in 2017, we had high total dissolved gasses, which are potentially lethal to fish,” aid Jim Fredericks, Fish and Game’s Fisheries Bureau Chief. “In 2017, we chose to release the fish allocated for Hells Canyon at Rapid River instead, to ensure that they survived. For that reason, we have hardly any two-year-old fish coming back to Hells Canyon this year.”

Only hatchery Chinook with a clipped adipose fin may be kept by anglers, and all others must be released unharmed. Chinook anglers are restricted to barbless hooks.

Anglers should refer to the 2019 spring Chinook salmon seasons and rules brochure for other rules and special restrictions, which will be available online in early April, and in paper form prior to the spring Chinook season at Fish and Game offices and license vendors.

The Fish and Game Commission is scheduled to decide on summer Chinook salmon fisheries on the Lochsa River, South Fork Salmon River and upper Salmon River at its May meeting. Fish return to those areas later than to the Clearwater River and Rapid River hatcheries, allowing fishery managers more time to develop season proposals.
