Looking at the link posted below, it seems like we get into trouble with overharvest when the total kill exceeds 400,000. I'm basing this upon the large variations in harvest that have occurred from the 1990's onward, and lower harvests since 2010. Thoughts on that interpretation:
Annual deer harvest totalsI'm also thinking, based on what others have said on here, and from the harvest over the last decade or so, that Wisconsin hunters either shoot all the deer they want (as a whole, certainly not true for each individual hunter) or are no longer willing to risk overharvest, after learning from the years of high harvest and subsequent low populations.
If that is true, it would suggest that the DNR needs to take hunter willingness more into account when setting harvest goals and regulations. One question I don't hear anyone asking, on a statewide or management unit level, is "how many deer are you willing to shoot?" Natural resource management is always more about managing the people than the resource, and in this case, it would especially be true. They need to get an accurate picture of what the hunters desire to harvest. It looks to me like that number might be about 300,000, but is likely on the low side since most hunters in the northern part of the state are not likely shooting as many deer as they would like to, right?
