At 2.54 wolves per pack, Zone 4 in Wisconsin’s northcentral and northeast is running thin. That is the lowest average pack size in the state, according to the Department of Natural Resources’ 2026 winter wolf survey, released June 25. The figure sits against a high of 4.34 wolves per pack in Zone 1, the far north and northwest, where 511 of the state’s estimated 1,162 wolves live.
The DNR’s Wolf Advisory Committee heard the numbers in a virtual meeting. Lydia Margenau, a DNR wildlife research scientist, called the statewide 5% decline from the previous year a slight fluctuation around a mean.
The population sits 3% below the five-year average. Margenau said the data suggests the state’s wolf population has reached its biological carrying capacity. Pack territories tell a different story in one zone.
In Zones 1 through 4, territories averaged 54 square miles. In Zone 5, the central forest zone, they averaged 32 square miles.
Margenau attributed the smaller range to higher prey density in that area. Zone 5 held 191 wolves. The estimate does not count wolves not associated with packs.
It also excludes animals that have dispersed out of the state’s core wolf range. The statistical confidence range runs from 1,026 to 1,307 wolves, and from 287 to 359 packs. Randy Johnson, DNR large carnivore specialist, led the meeting.
He said the full 2026 wolf monitoring report should be posted to the DNR’s website in the coming days. The agency produces an annual report partly as a requirement to the U.S. Fish and Wildlife Service.
Zone 2, in the northeast, had 273 wolves. Zone 3, in the northwest, had 126. Seven other wolves were not attributed to any zone.
The gray wolf in Wisconsin and most of the Lower 48 remains under federal protection. The DNR survey is a winter count, conducted when packs are easiest to track on snow.
Biologists use radio collars, track surveys, and public reports to build the estimate. Margenau’s characterization of the population as settled into a natural equilibrium is the key takeaway. The number has hovered near 1,200 for several years.
The 2026 estimate of 1,162 is within the range of normal variation. That stability, after decades of recovery from near extirpation in the state, is the story the data tells. Zone 4’s small pack size may reflect poorer habitat or lower prey availability in that management unit.
The DNR does not speculate on causes in the survey release. The numbers are raw.
They are what they are. The DNR’s Wolf Advisory Committee includes representatives from tribal nations, hunting groups, livestock producers, and conservation organizations. The committee does not set policy.
It reviews data and provides input. The June 25 meeting was a data briefing, not a decision session.
Wolf management in Wisconsin has been politically contentious. The 2021 court-ordered delisting led to a three-day hunting season that killed 218 wolves, far exceeding the quota. The population has since recovered to pre-hunt levels.
The current equilibrium suggests the habitat can support roughly this many animals, no more. The 1,162 figure is an estimate. The confidence interval is wide.
The DNR is clear about that. The real number could be 1,026.
It could be 1,307. Either way, the trend is flat. Zone 1, with 511 wolves, holds nearly half the state’s population.
That is the core range. Dense forest, low human density, abundant deer.
The wolves are there because they can be. The full report will include more detail on mortality, reproduction, and depredation. Those numbers will come in the coming days.
For now, the headline is stability. The wolves are not growing. They are not crashing.
They are holding.
