Wisconsin's 87-Season Arc: The Rise and Fall of a Deer Empire

ITHE OLDEST RECORD

One state's harvest across eighty-seven seasons

Harvest histories usually cover relatively recent years, and most county-level records in our database are brief. Wisconsin starts in 1939; Iowa, our next-longest county record, starts in 2001. Wisconsin's reach is unusual. County harvest tables begin with 1939 and continue without a missing season until 2025, spanning a world war and the age of interstate highways, the continent-wide whitetail population surge, and the emergence of chronic wasting disease. Across the twelve states in our collection, no comparable record exceeds these 87 consecutive seasons. Only here can we track yearly deer harvest all the way from the early swings between abundance and scarcity to its high point and later downturn.

IISCARCITY AND OVERCORRECTION

Early management years: 1939 to 1959

Frequent changes to hunting rules give the earliest decades their experimental character. Harvest swung sharply. A wartime season allowing any deer raised the 1943 total to 122,525, roughly 2.8 times the tally for 1942 and 4.4 times what hunters took during 1944. Harvest subsequently dropped below 20,000, bottoming out in 1953 at 19,478. That was under a sixth of the total from 1943. Wisconsin's lessons in managing deer played out in public. Hunts restricted to bucks, short openings allowing any deer, and political arguments about the number of antlerless permits the state would accept created a jagged harvest history. It accurately reflects managers trying different season and permit rules and observing the results. These early totals have the poorest precision anywhere in the record. Use them to judge the direction and size of changes, without expecting accuracy down to each deer.

During the 1940s, a wartime hunt in Wisconsin took 122,500 deer within one season. A decade afterward, yearly harvest sank under 20,000. Learning to manage deer was a public process for the state.

IIITHE MANAGED EXPLOSION

1960 to 2000: 62,102 deer at the start, a peak at the finish

Beginning with the 1960s, the jagged record gives way to an upward trend. Harvest crossed 100,000 for the first time during 1965, retreated under that mark during 1970 to 1973, with totals running from 79,364 up to 90,539, then exceeded 100,000 in each season beginning with 1974. This record by itself does not tell us whether edges along farmland, regrowing forests, mild winters, or an increasingly mature permit system helped drive that growth. Harvest cleared 200,000 during 1982 and 300,000 by the latter part of the 1980s, then reached 494,407 during 1999. The record's largest reported harvest arrived in 2000, when hunters took 615,293 deer. This northern state's steep increase in yearly harvest over forty years captured the broader American whitetail boom on a smaller scale. The data do not establish the reason that particular season produced the peak.

IVTHE DESCENT

A lower harvest plateau amid herd reduction and disease

After 2000, harvest totals dropped in stages instead of falling steadily. They fell sharply from 518,553 in 2007 to 329,103 by 2009, with later peaks reaching lower levels. Efforts to reduce the herd and the arrival of chronic wasting disease overlapped with this decline, but the harvest series does not measure their effects separately. Wisconsin pursued planned herd reduction during the 2000s because deer numbers were above unit population goals across much of the state. The state encouraged heavy antlerless harvest through measures including extended either-sex seasons and earn-a-buck, aiming to lower deer density toward those goals. During the same period, chronic wasting disease changed management in affected zones. It was first detected in Wisconsin in 2002 near Mount Horeb, in Dane and Iowa counties in south-central Wisconsin. The reported harvest for the 2025 season was 345,207, a decline of 43.9% from the 2000 peak of 615,293. Over one generation, the herd's harvest output fell by more than two-fifths.

The final stretch also becomes more level. Beginning with 2014, harvest settles into a range running from 290,000 up to 345,000. No season exceeds 56.1% of the harvest recorded in 2000; 2025 leads this stretch with 345,207. These harvest data, by themselves, do not explain the leveling off. WDNR has a continuous statewide harvest record beginning in 1960. Reporting therefore has no break in 2014. The chart switches its underlying source in 1960.

VTHE SEAM

Two source periods with the junction clearly shown

We build this long harvest history from separate sources and make their junction explicit. For 1960 to 2025, the plotted values come from Wisconsin DNR's continuous published record of statewide harvest. Because that record starts in 1960, values covering 1939 to 1959 add together all county rows from WDNR's historical table. It contains 68 counties; 39 reported during only part of that period. Sources change in 1960. Moving from 1959 to 1960 combines an actual harvest change with a reporting-source change, so avoid interpreting that step as the swing within a single year. You can confidently read the overall pattern: scarcity, rapid growth, then decline. The drop between 2000 and 2025 is 43.9%, with harvest starting at 615,293 and falling to 345,207. That entire comparison uses the statewide record, without spanning the source change.

VIWHAT THE ARC MEANS

A herd's full rise and fall

Wisconsin's data trace the climb and retreat of yearly deer harvest. Across 87 seasons, harvest swung up and down under early management, grew through the managed decades, and peaked at a total of 615,293. A hunter from 1954 would have found that number unbelievable. Harvest later dropped to 56% of the peak, with 345,207 taken during 2025. Looking toward 2026, the useful lesson is to understand today's range rather than long for the high in 2000, a particular peak that was partly artificial. Recent Wisconsin harvest totals occupy a band below the boom years but well above the postwar low. These data alone do not tell us how much management or disease contributed to the decline.
