Dean Beyer, a wildlife research biologist for the DNR, who is serving as the co-principal investigator for the Michigan Predator-Prey Project, said it will consist of three three-year-long phases of field work. Field work for the first phase, in which fawn mortality rates in low-snowfall zones of the U.P. were investigated, began in 2009. The second phase's field work, focusing on fawn mortality rates in mid-snowfall zones in Iron County, is ongoing.
"When we complete that, we'll move up to the high-snowfall zone (in January 2017)," Beyer said.
Once the third phase's field work is done, Beyer said he expects the project to run for a few more years to analyze the collected data.
Even though the project is still years away from completion, research done in the low-snowfall zone has already provided valuable information about fawn survival rates.
"In the low-snowfall zone...we had annual fawn survival range from 35 percent to 59 percent," Beyer said.
"Coyotes were an important predator of fawns in phase one," Beyer added.
According to their website, the Predator-Prey Project uses netted "clover" traps to capture adult does during the winter months. If they are pregnant, researchers outfit them with a radio-tracking collar and an implanted transmitter which will report where they give birth to their fawns.
"It ... increases our chances to find and capture a young fawn," noted Beyer.
The presence of livestock dump sites near the zone being studied in phase one may have been a confounding factor, as Beyer said it could have reduced the odds of wolves attempting to eat fawns in the area.
"They had this readily-available food source," Beyer said.
Still, he noted the Michigan Predator-Prey Project's extreme level of depth and peninsula-wide scope ensures it will be highly useful.
"It's a very comprehensive study - there's not many studies out there that investigate all of these factors simultaneously," Beyer said.

"We wanted to look at the role of predation and winter habitat on fawn survival," said Dean Beyer, a wildlife researcher with Michigan's DNR.
"We jumped into the UP because of the deer population trends," Beyer said.
Belant and Beyer discovered two packs of wolves in the area.
"They (wolves) were hitting carcasses," Beyer said. "That influenced the predation on fawns and might have reduced it. It will be interesting to see what happens in the mid-snow zone where there is no agriculture or cattle dump."
Phase 2 begins next winter in Iron County, Phase 1, in Delta and Menominee counties, collected predator data points for 650,000 locations, Beyer said.

"As temperatures have increased, we're seeing some association with these declining populations," said Dean Beyer Jr., a wildlife research biologist with the Michigan Department of Natural Resources.
Scientists have ruled out attacks from resurgent gray wolves as a significant contributor, Beyer said.
Wolf numbers increasing throughout upper Midwest - The Mining Journal, 5 May 2005 [cached]
Dean Beyer, wildlife biologist for the Michigan Department of Natural Resources in Marquette, said the preliminary estimate for wolves in the Upper Peninsula is 408 animals in 86 packs.That number is up from an estimated 380 wolves in the U.P. last winter.
Researchers also found a wolf in Michigan's Lower Peninsula last year for the first time since 1910.It was fitted with a radio collar and monitored for several months before a coyote trapper mistakenly killed it, Beyer said.

Dean Beyer, MDNR moose biologist, said the pulse rate emitted by the police scanner mimicked that of the collared bull, but the tone was slightly off.It was a close enough match, however, to warrant an investigation, he said.
Although Michigan wildlife managers are in the process of developing new population modeling techniques, the western Upper Peninsula moose herd appears to be growing by around 4 to 6 percent, said Michigan Biologist Dean Beyer.Previous population data was skewed-in part-because it did not account for disbursing animals, Beyer explained.
