Near Elkhorn DNR INVESTIGATING COUGAR TRACKS IN WALWORTH COUNTY |
FITCHBURG – Department of Natural
Resources biologists continue to look into the possible presence of cougars in
southern Wisconsin based on observations of animal tracks over the past month.
The latest probe involves cougar tracks found March
7 northeast of Elkhorn in Walworth County by state conservation warden Jason
Roberts, Sturtevant. DNR mammal ecologist Adrian Wyedeven, Park Falls, verified
the tracks as that of a cougar from photos taken at the scene. A hair sample
was collected for genetic analysis to determine whether the animal is a North
American cougar.
The location of the possible cougar tracks near
Elkhorn is about 23 miles east-southeast of a cougar sighting two months ago in
Rock County east of Milton.
“It is possible these (tracks) are the same cougar’s,
although tracks measured at the Elkhorn site seemed somewhat larger. Difference
in track sizes can occur with different snow surface conditions or whether the
front or hind feet are being observed,” said Mr. Wydeven.
“Front feet are larger than hind feet on cougars,”
he continued, “and it is hoped that genetic testing will be able to determine
the relationships of these cougars to each other.”
Urine and blood samples from the ‘Milton’ cougar
were submitted for genetic testing at the U.S. Forest Service Rock Mountain
Research Station in Missoula, Montana, soon after they were collected on Jan.
18.
“Genetic testing has so far shown that the Milton
cougar had a mother that was of a North American subspecies, but the father’s
side has not yet been determined nor has its gender,” said the ecologist.
Identifying the paternal or male inheritance will
indicate to biologists whether the cougar is of North American origin and wild
or a domestic escapee if it’s of South American origin. If inheritance on both
the mother’s and father’s side are of North American origins, it makes it more
likely that the cougar is native, but still could have escaped from captivity,
according to Mr. Wydeven.
The last known wild cougars in Wisconsin, also
called mountain lion or puma, disappeared during the early part of the 20th
Century. Although reports of cougars have been received around the state over
the ensuing years, none have been documented as wild cats since the early
1900s. There have been several instances of captive cougars in Wisconsin
escaping into the wild before recapture or disappearance. Cougars have been
documented in Minnesota, Iowa, Missouri and Illinois.
Cougars are listed as “protected wild animals” in
Wisconsin which means a permit would be required from DNR before someone could
kill the animal.
More apparent
cougar tracks
Since Jan. 19, several other observations of cougar
tracks have been investigated in Rock County. An apparent cougar track was
spotted by a hiker along the Ice Age Trail on the east side of Janesville while
possible tracks were seen near Clinton, about two miles north of the Illinois
border.The latter tracks were verified by a DNR technician as being a cougar’s.
Possible cougar tracks were found west of Beloit on
March 5 in the Town of Newark, but these tracks were more than two days old and
could not be verified as that of a cougar.
The public is encouraged to contact their nearest
DNR office if they observe a large cat, but wildlife biologists remind citizens
not to approach the animal, stop, stand tall, do not run and pick-up small
children.
“Take digital photos of the animal and its tracks if
at all possible and use something such as a tape measure to show the size of
the track. Also record the time and exact location of the observation,” said
DNR wildlife supervisor Doug Fendry, Fitchburg.
Genetic
analysis of cougars
Genetic analysis of cougar samples from Wisconsin is
being done by the U.S. Forest Service genetic laboratory at the Rocky Mountain
Research Station in Missoula, Montana under the direction of Michael Schwartz.
The lab will be examining the blood sample from the Milton cougar to attempt to
determine gender, inheritance and possibly the specific population of origin.
The lab will also examine the Elkhorn sample to determine if the two cougars
are related.
