The deer population has been declining statewide since around 2008-2009. The sharp decline in harvest numbers despite doubling the number of allowed tags and adding an extra gun season points indisputably to a sharply declining population. Some areas of the state started seeing this decline years ago around 2009. Other areas took longer to begin to show a noticeable decline. The few areas that held on the longest are starting to show a decline also. For instance. I saw a sharp decline in Vinton county around 2008-9. As a result I started hunting champaign county. Just this year I've now started to see the same trend here. Last year ohio had the lowest total harvest in something like 13 years. This is despite adding extra tags, the addition of a bonus gun season that added 20% more days afield with a gun. Sunday hunting was just allowed in 1998. Yet we just had a harvest last season that was the worst in well over a decade.
If you removed the extra tags, the two day early muzzleloader, and the Sunday hunting. I'm willing to bet Ohio would have the worst harvest seen since before all of that was added. So while we've added tons of opportunity, we've still seen a decline. This means that if that "tons of opportunity" was removed the decline would be much much more noticeable.
Now. Where there is desert there is usually an oasis. You will still hear of people who have little issues with the deer population. These are typically spots where the hunter had a lot of control over the property. Like MK11 above, he owns the farm, works hard to make it attractive to deer, has little pressure, and if I remember correctly (correct me if I'm wrong buddy) Doesn't really bow hunt but rather only gun. Can you still create a little slice of heaven for deer? Sure. Are they getting rare to find naturally? Without a doubt.
Hunting in ohio is still without a doubt good, but its gone downhill considerably from where it was just 6 years ago.
