Wolves crossing the Straits of Mackinaw to the Lower Peninsula (LP) seems unlikely, but it was reported three crossed on ice near Mackinac Bridge. A shipping lane is open all winter but it froze long enough. It turned out the canines were dogs and not wolves.
The Northern LP is heavily populated with people so it is likely human/wolf conflicts would require DNR intervention. Coyotes sometimes take livestock and the DNR receives trapping requests for offending animal removal. This occurred near Rogers City. The farmer was issued a permit to trap the coyote. To everyone’s surprise a wolf was trapped. That is the only wolf known from the LP in almost a century. No tracks, sightings, characteristic predation, or road kills have been found since.
Four wolves were reintroduced to the Upper Peninsula (UP) in 1974 but vigilantes illegally shot two, one was trapped and killed, and a vehicle hit the fourth. Later wolves immigrated on their own from north of Lake Superior in Minnesota, expanded into Wisconsin and reestablished a population in Michigan. They arrived in the western UP about 1984. I personally saw one in the eastern UP that year.
I was conducting contract insect research for the MDNR in Schoolcraft County in a forest clear cut when a wolf stood with forelegs on a cut tree to look at me. My 85 lb. German Shepard was 300 feet to the east. The wolf was about 300 feet to the west. The wolf was larger than a coyote. Coyote’s weigh about 35 lbs. Coyotes are skittish and depart quickly. The wolf paused to look at me before dropping to the ground and disappearing in the open clear cut. That is also typical wolf behavior, while coyotes typically run. I was amazed the wolf could sneak away unseen in a relatively open area. Jim Hammill, MDNR wolf biologist, agreed it was probably a wolf based on the behavior description.
Wolves are predators and were eradicated from Michigan. Following forest logging in the 1800’s, the deer population grew. Few hunters venture into the depths of regenerating forest and many prefer bucks with large antlers instead of does. The deer herds grew until the 1950’s, when a series of hard winters decimated the population. Since then deer herds grew with some reduction years.
The MDNR is responsible for managing wildlife population sizes where political and social motivations often have priority over ecological science. One MDNR wildlife biologist told me he knows hunting licenses pay his salary so it makes it right to base his decisions on license fee promotion rather than sound ecological science. He tries to balance both when possible.
Devastation of plant and animal populations caused by deer feeding habitats has concerned people. Most people, however, do not read supporting ecological studies. Some State Parks and nature centers began politically challenging deer hunts to reduce the devastation. Hoffmaster State Park hosted a Trillium Festival where deer eliminated most trilliums and reduced other plant and animal populations. Objections to these hunts are often based on emotional responses and personal desires rather than nature niche ecology.
Four conservation groups visited Ody Brook Nature Sanctuary during September and were pleased with the abundance of native species compared to exotics species. The back 40 acres have been leased for hunting for decades and it helps keep the deer herd in ecological balance. Several years ago, the hunters told me poachers shot several deer and left them to rot in the woods. If the deer meat was processed, it would have been reported and hunters prosecuted. The sanctuary is surrounded by agricultural land so I suspect a local farmer did the poaching. The MDNR will issue harvest permits for deer causing damage to farmers, so poaching is not necessary. The same is true for wolves where they live. If wolves were present here, the deer population would probably not be as large and fewer would be killed annually on the road at Ody Brook. Unfortunately there would be social/political wolf problems in Kent County because of our large human and domestic animal populations. Wolves will kill pet dogs and domestic animals.
Wolves in the UP now exceed the target population of 200. Some conflicts exist between farmers and wolves. The MDNR inspects problems and specific wolves are removed. This helps prevent wolf packs from learning to take domestic animals. I waited to share this until after the recent wolf ballot election to avoid the ire of people voting based on emotion and personal interest and those preferring scientific research study decisions. Details of the role of wolves in ecosystems will be described in Part 2 of this article next week. Suffice it to say for now, I am pleased both issues were defeated. The first ballot issue was to create a hunting season on wolves managed by the MDNR. It was the better of the two but political pressure similar to deer hunting pressure would be significant. The 2nd ballot issue would have placed decision control with a small politically appointed group that could accept or reject scientific findings. I expect there will be a time when managed hunts might be appropriate.
