Michigan's deer harvest draws from two herds with almost no common ground. In the Upper Peninsula, winter drives sharp rises and falls: heavy snow and prolonged cold kill deer outright and leave surviving deer without enough food. Harvest then swings with the harshness of earlier winters. The southern Lower Peninsula has gentler winters and food from farms. Michigan DNR reports that winter deaths rarely damage the deer population there. The 2024 season made the difference clear: a mild winter helped drive a 15 to 21% increase in UP buck harvest, while southern buck harvest remained unchanged.
KEY FINDINGS
- For 2024, bucks taken in the Upper Peninsula increased by 15 to 21%. DNR credited that recovery to the 2023 to 24 winter, which was unusually mild and followed two harsh winters. Meanwhile, Southern Lower Peninsula buck harvest changed little from the preceding year.
- In the UP, winter harshness drives the cycle. Heavy snow and extended cold kill deer outright or leave them starving. DNR identified winter severity as the main reason harvest recovered.
- Farming defines the southern Lower Peninsula. According to Michigan DNR, deer populations stay high across much of that area, with winter deaths seldom reducing them. Diseases including EHD can still lower deer numbers locally.
- A single Michigan harvest figure obscures the regional picture by adding the regions together. For 2024, reported harvest was about 300,000; allowing for deer that went unreported puts the estimate nearer 373,000.
ITwo herds, one license
A bridge crosses a divide in deer biology
Crossing the Mackinac Bridge means crossing between different deer herds. Extensive woods characterize the Upper Peninsula, along with lengthy winters, heavy snow and little farmland. Michigan DNR identifies winter severity as the chief limit on deer numbers there. Farther south, the southern Lower Peninsula lies in Corn Belt country. Gentler winters and farm-grown food sustain large deer populations. Both regions follow the same state's regulations, and their harvests enter a shared statewide total. In biological terms, though, they act much like separate states. Winter creates that divide.
IIThe UP winter machine
Snow and cold determine herd size, with effects that take time
The Michigan DNR says winter is the main factor affecting deer in the Upper Peninsula. Deep snow makes food harder to reach, and moving through it burns fat reserves. Severe winters have been followed by fewer fawns joining the herd and occasional declines in buck harvest. Harvest bounced back in the 2024 season. After two harsh winters and the unusually mild winter of 2023 to 24, UP buck harvest rose 15 to 21%. The DNR names the mild winter as one of the leading contributors to that rebound. Some UP hunters also see wolves as a factor; the DNR identifies winter severity as the main explanation for the swing.
Winter severity is Michigan DNR's main explanation for shifts in UP harvest. The agency estimated a 21% increase in Upper Peninsula deer harvest following the mild winter of 2023 to 24. Harsh winters have preceded harvest declines.
IIIThe stable south
Agriculture cushions the effects of weather
Conditions work the other way in the southern Lower Peninsula. Winters bring less hardship. Michigan DNR explains that generally mild winter conditions and plentiful food during summer leave the area's deer population seldom harmed by winter deaths. The agency considers those deaths a small influence there. Recent reporting instead highlights complaints about damaged crops across several counties, along with EHD outbreaks. During 2024, the UP's buck take rose by 15 to 21%; southern Lower Peninsula buck harvest barely changed, and antlerless harvest increased modestly. Mild winters characterize the south. According to Michigan DNR, deer populations stay high across much of that area.

The state total masks differences among regions

| Upper Peninsula | Southern Lower Peninsula | |
|---|---|---|
| Primary driver | Winter severity | Agriculture / density |
| Herd behavior | Boom-bust, on a winter lag | Stable, high |
| 2024 total harvest | Up 21% (mild winter) | Nearly unchanged |
| Winter-kill risk | High | Low |
Michigan's statewide harvest total combines counts from the Upper Peninsula and the northern and southern Lower Peninsula, obscuring the differences among those regions. Reported harvest for 2024 was near 300,000, while the estimate was closer to 373,000 after accounting for under-reporting. Hunters need to plan around their region. In the UP, the key measure is the severity of the past winter or two. In the southern Lower Peninsula, agriculture and access matter for planning rather than weather. Deer-management problems differ across Michigan's regions.
NOTES AND SOURCES
- During the 2024 season, bucks taken in the Upper Peninsula increased by ~15 to 21%. Michigan DNR credited the mild winter of 2023 to 24, which came after two harsh winters. Buck harvest in the Southern Lower Peninsula changed little, while antlerless harvest rose. The statewide reported take was about 299,517; accounting for unreported deer puts the estimate nearer 373,000.

- Some UP hunters point to wolf predation as a contributing factor. The Michigan DNR identifies winter severity as the main cause of changes from year to year. This analysis is limited to reports of which way regional harvest changed and the percentage of the UP rebound. A complete county-level harvest series for Michigan is still pending.
