Michigan once traded turkeys to Canada to replenish moose population in U.P.

Before Europeans arrived in Michigan, “moose were pretty much all over” the state, said Rachel Clark of the Michigan History Center.
After that arrival, the moose population declined as settlers began over-hunting the animal and damaging its habitat.
In response, 1935 brought the first attempt to bring moose back to the Upper Peninsula. But according to Steve Schmitt, a retired DNR wildlife veterinarian, that didn’t go so well.“As they’re clearing out the woods to create farms and those landscapes, they’re destroying the moose habitat,” she said. “So the moose are either dying or moving.”
“Deer had a biological weapon – basically a parasite called brain worm that doesn’t cause a problem in the deer, but when it gets into the moose, it will kill them,” he said. “As they cleared the forest up north, the deer population was able to increase, and that adversely affected the moose population.”
That didn’t stop wildlife specialists from trying. The second attempt came in the mid-1980s.
“The idea there was that the habitat was changing, becoming more advantageous to moose,” Schmitt said.
Algonquin Park in Ontario had an overabundance of moose at the time, Schmitt said, so the goal was to bring some of them over to Michigan.
In return, Schmitt said Michigan gave Ontario some wild turkeys.
Watch the translocation process below in the Archives of Michigan video. The process involves shooting the moose with a tranquilizer gun (Schmitt’s job), putting the animal in a sling, airlifting it to a processing area, crating the animal, and driving it in a truck to the release site in the U.P.

History of Moose
in Michigan
Moose are native to Michigan and occurred throughout all except the southwestern Lower Peninsula prior to European settlement. Moose disappeared from the Lower Peninsula in the 1890s, and only a few scattered individuals remained in the Upper Peninsula.
The interaction of several factors probably caused the decline of moose in Michigan. Extensive logging during the early 20th century eliminated millions
of acres of moose habitat. Loggers, miners and other
settlers also took these large animals for food. Another
factor thought to have contributed to the decline of the
population was brainworm (Parelaphostrongylus tenuis),
a nematode carried by white-tailed deer. Although the
brainworm has little effect on white-tailed deer, it can
cause a fatal neurological disease in moose. As the
Michigan deer population expanded rapidly in the
more open and brushy habitat created by the logging
and forest fires that followed European settlement,
the incidence of brainworm in the moose population
likely increased.

The state's first attempt to reintroduce moose in the
Upper Peninsula mainland occurred from 1934 to 1937,
when biologists trapped and transported 71 moose from
Isle Royale to the mainland. Most of these moose were
released in Keweenaw, Marquette and Schoolcraft
counties. Of the remaining moose, officials sent two to
the Detroit Zoo and six to the Cusino Wildlife Experimental
Station for study of basic moose biology. These studies
revealed information on the dates of the rutting season,
gestation period, rate of growth from birth to maturity,
types of food eaten and food preferences, and antler
development. At the time of capture, the Isle Royale
moose population was very high and moose had
depleted the forage on the island. As a result, moose
brought to the mainland were in poor physical condition,
and some developed serious infections after release.
Many of the introduced moose died from what was
described at the time as "circling disease," most likely
caused by the brainworm parasite. Although citizens
reported observing moose across the Upper Peninsula
in 1941, poaching continued as a threat to the population.
The poor condition of the translocated moose, combined
with poaching and high deer numbers, contributed to the
failure of this initial attempt to reintroduce moose on the
mainland.
During the 1950s and 1960s, citizens occasionally observed
moose in the Upper Peninsula, primarily in the eastern
counties. In the 1970s, biologists recognized changes in
the Upper Peninsula that were promising for moose. Most
notable was a decline in deer numbers in the northern
portions of the Upper Peninsula.

In the mid-1980s, the DNR translocated 59 moose from
Algonquin Provincial Park in Ontario, Canada and released
them in Marquette County. The goal of the moose reintroduction
was to produce a self-sustaining population of free-ranging
moose in the Upper Peninsula.

All of these moose were fitted with mortality-sensing radio
collars to help monitor the outcome of the reintroduction.
The translocated moose population increased through the
late 1980s and early 1990s in spite of a few losses each
year to brainworm and several other natural causes,
including falls off cliffs, fights during the rut and
complications while giving birth. Calf production and
survival through the first year of life were very good,
confirming that the habitat was suitable. Poaching losses
were virtually nonexistent, perhaps because the citizens
of the Upper Peninsula were involved with the project and
had adopted the new moose population as their own.

Moose are currently found in two areas of the Upper
Peninsula: the reintroduced population in Marquette,
Baraga and Iron counties, and a smaller remnant
population in the eastern UP, found primarily in Alger,
Schoolcraft, Luce and Chippewa counties.

During the most recent moose population survey in
January 2011, the DNR counted an estimated 433
animals in the western Upper Peninsula. No formal
survey of the eastern U.P. moose population is
conducted, but local biologists estimate there are
about 100 animals, based on field observations
and reports from the general public.
