This an exceptionally bad winter for local deer herd
This winter could go down as one of the harshest on record for northwoods wildlife.

With weeks to go until spring green-up, Department of Natural Resources Northern Region Area Supervisor Chuck McCullough said the combination of subzero days and deep snows may be historic.

“It’s probably one of our harshest winters,” McCullough, based in Antigo, said. “I have never seen numbers this high for as many stations as I’m seeing now in the north. It is extremely severe for the entire northwoods.”

DNR biologists use a winter severity index to gauge stress levels. Points are assigned for each day with snow deeper than 18 inches and temperatures below zero.

WSI measurements are recorded at 43 stations across the northern third of the state and in several east-central counties. Winter conditions are considered mild if a station accumulates less than 50 points, moderate between 51 and 80 points, severe between 81 and 100, and very severe if more than 100.

In the north, the numbers have shot into the “very severe category,” with the Summit Lake station at 126 by the latest count and Antigo close behind at about 120.

Similar numbers are being reported across much of the northern third of the state.

"We have received some reports of dead deer and turkey, especially in northern Wisconsin where snow is more than 30 inches deep in some areas," Tom Hauge, the DNR’s director of wildlife management, said. “While animals native to Wisconsin are equipped to handle snow and cold, too much for too long can overwhelm an individual animal's resources.”

McCullough said that while widespread deer deaths have not been reported, he expected that will begin soon.

“Between now and green-up is when we are going to see the deer mortality,” he said.

Across the state, DNR biologists are asking the public to report any observations of deaths. Concerned citizens can report their numbers to local wildlife biologists and technicians. Additionally, DNR biologists are working in the field this time of year, monitoring deer and their habitats and talking to loggers, foresters, trappers and others who frequent the winter woods.

Sam Jonas, DNR wildlife biologist for Iron County surveyed a 4-mile stretch near the Wisconsin-Michigan border that runs through a wintering area and observed about 70 deer and 16 turkeys.

"The deer are browsing cedar, hemlock and other brush in area," Jonas said. "I am sure we do have some winter mortality in areas, however, the deer I have seen in this wintering area look like they are faring pretty well so far, including the fawns. Late March and April is historically when we see winter mortality so I will be doing a lot of snowshoeing into deer yards at that time to check on things."

The harsh winter is also generating questions from the public about feeding deer. Mike Zeckmeister, DNR northern wildlife supervisor, said it is a legitimate and compassionate inquiry but one without an easy answer.

"I understand people want to try to help deer through a hard winter, but feeding can do more harm than good," he said.

Feeding unmixed corn or hay can actually be harmful to deer in late winter. A commercialized pellet—or mixes containing small quantities of corn, plus alfalfa, oats and soybeans, as well as various vitamins and minerals—is the best choice. The food should be spread out to reduce fighting, kept away from roads or snowmobile trails to avoid collisions, and placed near areas sheltered from the wind.

Deer feeding is regulated under Wisconsin law and is prohibited in counties affected by chronic wasting disease. In all other counties, feeding is limited to a maximum of 2 gallons per site. Feeding sites must be placed within 50 yards of a dwelling or a business building open to the public and may not be placed within 100 yards of a roadway with a posted speed limit of 45 mph or higher.

Officials said it is too early to determine what the impact will be on the fall deer hunting season.

"There is no question this winter will affect decisions concerning the deer season," Kevin Wallenfang, DNR big game ecologist, said. "We are watching this very closely and will adjust the 2014 antlerless deer quotas in response. Based upon what we've seen to date, northern Wisconsin deer hunters can expect to see a lot of buck-only units this fall. The availability of antlerless permits will be extremely low or at zero across the north, depending on the area."

Turkey flocks have also been hard hit, especially the birds that have not found feeding opportunities at feeders or in barnyards.

“They are in bad shape,” McCullough said. “The flocks are shrinking every day.”

Scott Walter, DNR upland wildlife ecologist, explained that although turkeys are very capable of surviving brief periods of cold and snow, the longer those conditions last the more likely birds will die. Young birds are likely to be the hardest hit, he said, as they don't have the fat reserves that allow adults to survive up to four weeks with minimal food."

The cold forces turkeys to either increase their food intake or burn more of their fat reserves to stay warm while deep or crusted snow makes it difficult to locate food on the ground. Powdery snow more than 12 inches deep makes it difficult for turkeys to travel in search of food.

As a result of poor production last spring and a severe winter, hunters might see fewer turkeys during the spring 2014 season.

"The levels of harvest that typify Wisconsin's spring and fall turkey seasons have little impact on population trends, however," Scott said. "Some hunters understandably have suggested reducing harvest during the upcoming spring and fall to help turkeys recover. Reducing permit levels, however, would greatly reduce hunter opportunity while doing little to help turkey populations."

Landowners interested in habitat enhancements to buffer turkeys against the effects of severe winter weather can receive grain seed for winter plots through the National Wild Turkey Federation Conservation Seed Program, which provides outdated corn as well as sorghum, highbush cranberry and flowering crab seedlings to federation members for reduced costs.

"These programs allow National Wild Turkey Federation members to make a significant contribution to wild turkey winter survival in the Upper Midwest," Rick Horton, National Wild Turkey Federation Midwest Conservation field supervisor, said.


SEVERE WINTER—The map depicts the Winter Severity Index (WSI) across northern Wisconsin. WSI is calculated by adding the number of days with a snow depth of at least 18 inches to the number of days when the minimum temperatures were 0 degree or below. Points accumulate through the winter. WSI of 50 or less is considered mild, 50 to 79 is moderate, 80 to 99 is severe, and over 100 is very severe.
